# Using Implicit Want to Open a Website

This section uses the operation of using a browser to open a website as an example. It is assumed that one or more browser applications are installed on the device. To ensure that the browser application can work properly, configure the [module.json5 file](../quick-start/module-configuration-file.md) as follows:

```json
{
  "module": {
    // ...
    "abilities": [
      {
        // ...
        "skills": [
          {
            "entities": [
              "entity.system.home",
              "entity.system.browsable"
              // ...
            ],
            "actions": [
              "action.system.home",
              "ohos.want.action.viewData"
              // ...
            ],
            "uris": [
              {
                "scheme": "https",
                "host": "www.test.com",
                "port": "8080",
                // Prefix matching is used.
                "pathStartWith": "query",
                "type": "text/*"
              },
              {
                "scheme": "http",
                // ...
              }
              // ...
            ]
          }
        ]
      }
    ]
  }
}
```

In the initiator UIAbility, use implicit Want to start the browser application.

```ts
import common from '@ohos.app.ability.common';

function implicitStartAbility() {
  let context = getContext(this) as common.UIAbilityContext;
  let wantInfo = {
    // Uncomment the line below if you want to implicitly query data only in the specific bundle.
    // bundleName: "com.example.myapplication",
    "action": "ohos.want.action.viewData",
    // entities can be omitted.
    "entities": ["entity.system.browsable"],
    "uri": "https://www.test.com:8080/query/student",
    "type": "text/plain"
  }
  context.startAbility(wantInfo).then(() => {
    // ...
  }).catch((err) => {
    // ...
  })
}
```

The matching process is as follows:

1. If **action** in the passed **want** parameter is specified and is included in **actions** under **skills** of the ability to match, the matching is successful.
2. If **entities** in the passed **want** parameter is specified and is included in **entities** under **skills** of the ability to match, the matching is successful.
3. If **uri** in the passed **want** parameter is included in **uris** under **skills** of the ability to match, which is concatenated into https://www.test.com:8080/query* (where * is a wildcard), the matching is successful.
4. If **type** in the passed **want** parameter is specified and is included in **type** under **skills** of the ability to match, the matching is successful.

When there are multiple matching applications, a dialog box is displayed for you to select one of them. The following figure shows an example.
