### Load balancing
Load balancing is supported by `group`.
This feature is available only for type `tcp` now.
```ini
# frpc.ini
[test1]
type = tcp
local_port = 8080
remote_port = 80
group = web
group_key = 123
[test2]
type = tcp
local_port = 8081
remote_port = 80
group = web
group_key = 123
```
`group_key` is used for authentication.
Proxies in same group will accept connections from port 80 randomly.
### Rewriting the Host Header
When forwarding to a local port, frp does not modify the tunneled HTTP requests at all, they are copied to your server byte-for-byte as they are received. Some application servers use the Host header for determining which development site to display. For this reason, frp can rewrite your requests with a modified Host header. Use the `host_header_rewrite` switch to rewrite incoming HTTP requests.

custom_domains = test.yourdomain.com
host_header_rewrite = dev.yourdomain.com
```
If `host_header_rewrite` is specified, the host header will be rewritten to match the hostname portion of the forwarding address.

If `host_header_rewrite` is specified, the Host header will be rewritten to match the hostname portion of the forwarding address.

### 负载均衡
可以将多个相同类型的 proxy 加入到同一个 group 中，从而实现负载均衡的功能。
目前只支持 tcp 类型的 proxy。
```ini
# fprc.ini
[test1]
type = tcp
local_port = 8080
remote_port = 80
group = web
group_key = 123
[test2]
type = tcp
local_port = 8081
remote_port = 80
group = web
group_key = 123
```
用户连接 frps 服务器的 80 端口，frps 会将接收到的用户连接随机分发给其中一个存活的 proxy。这样可以在一台 frpc 机器挂掉后仍然有其他节点能够提供服务。
要求 `group_key` 相同，做权限验证，且 `remote_port` 相同。
### 修改 Host Header
通常情况下 frp 不会修改转发的任何数据。但有一些后端服务会根据 http 请求 header 中的 host 字段来展现不同的网站，例如 nginx 的虚拟主机服务，启用 host-header 的修改功能可以动态修改 http 请求中的 host 字段。该功能仅限于 http 类型的代理。
......@@ -525,6 +553,22 @@ host_header_rewrite = dev.yourdomain.com
原来 http 请求中的 host 字段 `test.yourdomain.com` 转发到后端服务时会被替换为 `dev.yourdomain.com`。
### 设置 HTTP 请求的 header
对于 `type = http` 的代理，可以设置在转发中动态添加的 header 参数。
```ini
# frpc.ini
[web]
type = http
local_port = 80
custom_domains = test.yourdomain.com
host_header_rewrite = dev.yourdomain.com
header_X-From-Where = frp
```
对于参数配置中所有以 `header_` 开头的参数(支持同时配置多个)，都会被添加到 http 请求的 header 中，根据如上的配置，会在请求的 header 中加上 `X-From-Where: frp`。
### 获取用户真实 IP
目前只有 **http** 类型的代理支持这一功能，可以通过用户请求的 header 中的 `X-Forwarded-For` 和 `X-Real-IP` 来获取用户真实 IP。

Package context stores values shared during a request lifetime.
Note: gorilla/context, having been born well before `context.Context` existed,
does not play well > with the shallow copying of the request that
[`http.Request.WithContext`](https://golang.org/pkg/net/http/#Request.WithContext)
(added to net/http Go 1.7 onwards) performs. You should either use *just*
gorilla/context, or moving forward, the new `http.Request.Context()`.
For example, a router can set variables extracted from the URL and later
application handlers can access those values, or it can be used to store
sessions values to be saved at the end of a request. There are several
others common uses.
The idea was posted by Brad Fitzpatrick to the go-nuts mailing list:
http://groups.google.com/group/golang-nuts/msg/e2d679d303aa5d53
Here's the basic usage: first define the keys that you will need. The key
type is interface{} so a key can be of any type that supports equality.
Here we define a key using a custom int type to avoid name collisions:
package foo
import (
"github.com/gorilla/context"
)
type key int
const MyKey key = 0
Then set a variable. Variables are bound to an http.Request object, so you
need a request instance to set a value:
context.Set(r, MyKey, "bar")
The application can later access the variable using the same key you provided:
func MyHandler(w http.ResponseWriter, r *http.Request) {
// val is "bar".
val := context.Get(r, foo.MyKey)
// returns ("bar", true)
val, ok := context.GetOk(r, foo.MyKey)
// ...
}
And that's all about the basic usage. We discuss some other ideas below.
Any type can be stored in the context. To enforce a given type, make the key
private and wrap Get() and Set() to accept and return values of a specific
type:
type key int
const mykey key = 0
// GetMyKey returns a value for this package from the request values.
func GetMyKey(r *http.Request) SomeType {
if rv := context.Get(r, mykey); rv != nil {
return rv.(SomeType)
}
return nil
}
// SetMyKey sets a value for this package in the request values.
func SetMyKey(r *http.Request, val SomeType) {
context.Set(r, mykey, val)
}
Variables must be cleared at the end of a request, to remove all values
that were stored. This can be done in an http.Handler, after a request was
served. Just call Clear() passing the request:
context.Clear(r)
...or use ClearHandler(), which conveniently wraps an http.Handler to clear
variables at the end of a request lifetime.
The Routers from the packages gorilla/mux and gorilla/pat call Clear()
so if you are using either of them you don't need to clear the context manually.

Package mux implements a request router and dispatcher.
The name mux stands for "HTTP request multiplexer". Like the standard
http.ServeMux, mux.Router matches incoming requests against a list of
registered routes and calls a handler for the route that matches the URL
or other conditions. The main features are:
* Requests can be matched based on URL host, path, path prefix, schemes,
header and query values, HTTP methods or using custom matchers.
* URL hosts, paths and query values can have variables with an optional
regular expression.
* Registered URLs can be built, or "reversed", which helps maintaining
references to resources.
* Routes can be used as subrouters: nested routes are only tested if the
parent route matches. This is useful to define groups of routes that
share common conditions like a host, a path prefix or other repeated
attributes. As a bonus, this optimizes request matching.
* It implements the http.Handler interface so it is compatible with the
standard http.ServeMux.
Let's start registering a couple of URL paths and handlers:
func main() {
r := mux.NewRouter()
r.HandleFunc("/", HomeHandler)
r.HandleFunc("/products", ProductsHandler)
r.HandleFunc("/articles", ArticlesHandler)
http.Handle("/", r)
}
Here we register three routes mapping URL paths to handlers. This is
equivalent to how http.HandleFunc() works: if an incoming request URL matches
one of the paths, the corresponding handler is called passing
(http.ResponseWriter, *http.Request) as parameters.
Paths can have variables. They are defined using the format {name} or
{name:pattern}. If a regular expression pattern is not defined, the matched
variable will be anything until the next slash. For example:
r := mux.NewRouter()
r.HandleFunc("/products/{key}", ProductHandler)
r.HandleFunc("/articles/{category}/", ArticlesCategoryHandler)
r.HandleFunc("/articles/{category}/{id:[0-9]+}", ArticleHandler)
Groups can be used inside patterns, as long as they are non-capturing (?:re). For example:
r.HandleFunc("/articles/{category}/{sort:(?:asc|desc|new)}", ArticlesCategoryHandler)
The names are used to create a map of route variables which can be retrieved
calling mux.Vars():
vars := mux.Vars(request)
category := vars["category"]
Note that if any capturing groups are present, mux will panic() during parsing. To prevent
this, convert any capturing groups to non-capturing, e.g. change "/{sort:(asc|desc)}" to
"/{sort:(?:asc|desc)}". This is a change from prior versions which behaved unpredictably
when capturing groups were present.
And this is all you need to know about the basic usage. More advanced options
are explained below.
Routes can also be restricted to a domain or subdomain. Just define a host
pattern to be matched. They can also have variables:
r := mux.NewRouter()
// Only matches if domain is "www.example.com".
r.Host("www.example.com")
// Matches a dynamic subdomain.
r.Host("{subdomain:[a-z]+}.domain.com")
There are several other matchers that can be added. To match path prefixes:
r.PathPrefix("/products/")
...or HTTP methods:
r.Methods("GET", "POST")
...or URL schemes:
r.Schemes("https")
...or header values:
r.Headers("X-Requested-With", "XMLHttpRequest")
...or query values:
r.Queries("key", "value")
...or to use a custom matcher function:
r.MatcherFunc(func(r *http.Request, rm *RouteMatch) bool {
return r.ProtoMajor == 0
})
...and finally, it is possible to combine several matchers in a single route:
r.HandleFunc("/products", ProductsHandler).
Host("www.example.com").
Methods("GET").
Schemes("http")
Setting the same matching conditions again and again can be boring, so we have
a way to group several routes that share the same requirements.
We call it "subrouting".
For example, let's say we have several URLs that should only match when the
host is "www.example.com". Create a route for that host and get a "subrouter"
from it:
r := mux.NewRouter()
s := r.Host("www.example.com").Subrouter()
Then register routes in the subrouter:
s.HandleFunc("/products/", ProductsHandler)
s.HandleFunc("/products/{key}", ProductHandler)
s.HandleFunc("/articles/{category}/{id:[0-9]+}"), ArticleHandler)
The three URL paths we registered above will only be tested if the domain is
"www.example.com", because the subrouter is tested first. This is not
only convenient, but also optimizes request matching. You can create
subrouters combining any attribute matchers accepted by a route.
Subrouters can be used to create domain or path "namespaces": you define
subrouters in a central place and then parts of the app can register its
paths relatively to a given subrouter.
There's one more thing about subroutes. When a subrouter has a path prefix,
the inner routes use it as base for their paths:
r := mux.NewRouter()
s := r.PathPrefix("/products").Subrouter()
// "/products/"
s.HandleFunc("/", ProductsHandler)
// "/products/{key}/"
s.HandleFunc("/{key}/", ProductHandler)
// "/products/{key}/details"
s.HandleFunc("/{key}/details", ProductDetailsHandler)
Note that the path provided to PathPrefix() represents a "wildcard": calling
PathPrefix("/static/").Handler(...) means that the handler will be passed any
request that matches "/static/*". This makes it easy to serve static files with mux:
func main() {
var dir string
flag.StringVar(&dir, "dir", ".", "the directory to serve files from. Defaults to the current dir")
flag.Parse()
r := mux.NewRouter()
// This will serve files under http://localhost:8000/static/<filename>
r.PathPrefix("/static/").Handler(http.StripPrefix("/static/", http.FileServer(http.Dir(dir))))
srv := &http.Server{
Handler: r,
Addr: "127.0.0.1:8000",
// Good practice: enforce timeouts for servers you create!
WriteTimeout: 15 * time.Second,
ReadTimeout: 15 * time.Second,
}
log.Fatal(srv.ListenAndServe())
}
Now let's see how to build registered URLs.
Routes can be named. All routes that define a name can have their URLs built,
or "reversed". We define a name calling Name() on a route. For example:
r := mux.NewRouter()
r.HandleFunc("/articles/{category}/{id:[0-9]+}", ArticleHandler).
Name("article")
To build a URL, get the route and call the URL() method, passing a sequence of
key/value pairs for the route variables. For the previous route, we would do:
url, err := r.Get("article").URL("category", "technology", "id", "42")
...and the result will be a url.URL with the following path:
"/articles/technology/42"
This also works for host and query value variables:
r := mux.NewRouter()
r.Host("{subdomain}.domain.com").
Path("/articles/{category}/{id:[0-9]+}").
Queries("filter", "{filter}").
HandlerFunc(ArticleHandler).
Name("article")
// url.String() will be "http://news.domain.com/articles/technology/42?filter=gorilla"
url, err := r.Get("article").URL("subdomain", "news",
"category", "technology",
"id", "42",
"filter", "gorilla")
All variables defined in the route are required, and their values must
conform to the corresponding patterns. These requirements guarantee that a
generated URL will always match a registered route -- the only exception is
for explicitly defined "build-only" routes which never match.
Regex support also exists for matching Headers within a route. For example, we could do:
r.HeadersRegexp("Content-Type", "application/(text|json)")
...and the route will match both requests with a Content-Type of `application/json` as well as
`application/text`
There's also a way to build only the URL host or path for a route:
use the methods URLHost() or URLPath() instead. For the previous route,
we would do:
// "http://news.domain.com/"
host, err := r.Get("article").URLHost("subdomain", "news")
// "/articles/technology/42"
path, err := r.Get("article").URLPath("category", "technology", "id", "42")
And if you use subrouters, host and path defined separately can be built
as well:
r := mux.NewRouter()
s := r.Host("{subdomain}.domain.com").Subrouter()
s.Path("/articles/{category}/{id:[0-9]+}").
HandlerFunc(ArticleHandler).
Name("article")
// "http://news.domain.com/articles/technology/42"
url, err := r.Get("article").URL("subdomain", "news",
"category", "technology",
"id", "42")
Mux supports the addition of middlewares to a Router, which are executed in the order they are added if a match is found, including its subrouters. Middlewares are (typically) small pieces of code which take one request, do something with it, and pass it down to another middleware or the final handler. Some common use cases for middleware are request logging, header manipulation, or ResponseWriter hijacking.
type MiddlewareFunc func(http.Handler) http.Handler
Typically, the returned handler is a closure which does something with the http.ResponseWriter and http.Request passed to it, and then calls the handler passed as parameter to the MiddlewareFunc (closures can access variables from the context where they are created).
A very basic middleware which logs the URI of the request being handled could be written as:
func simpleMw(next http.Handler) http.Handler {
return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
// Do stuff here
log.Println(r.RequestURI)
// Call the next handler, which can be another middleware in the chain, or the final handler.
next.ServeHTTP(w, r)
})
}
Middlewares can be added to a router using `Router.Use()`:
r := mux.NewRouter()
r.HandleFunc("/", handler)
r.Use(simpleMw)
A more complex authentication middleware, which maps session token to users, could be written as:
// Define our struct
type authenticationMiddleware struct {
tokenUsers map[string]string
}
// Initialize it somewhere
func (amw *authenticationMiddleware) Populate() {
amw.tokenUsers["00000000"] = "user0"
amw.tokenUsers["aaaaaaaa"] = "userA"
amw.tokenUsers["05f717e5"] = "randomUser"
amw.tokenUsers["deadbeef"] = "user0"
}
// Middleware function, which will be called for each request
func (amw *authenticationMiddleware) Middleware(next http.Handler) http.Handler {
return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
token := r.Header.Get("X-Session-Token")
if user, found := amw.tokenUsers[token]; found {
// We found the token in our map
log.Printf("Authenticated user %s\n", user)
next.ServeHTTP(w, r)
} else {
http.Error(w, "Forbidden", http.StatusForbidden)
}
})
}
r := mux.NewRouter()
r.HandleFunc("/", handler)
amw := authenticationMiddleware{}
amw.Populate()
r.Use(amw.Middleware)
Note: The handler chain will be stopped if your middleware doesn't call `next.ServeHTTP()` with the corresponding parameters. This can be used to abort a request if the middleware writer wants to.
