+# Want
+
+Want is a carrier for information transfer between objects (application components). Want can be used as a parameter of **startAbility** to specify a startup target and information that needs to be carried during startup, for example, **bundleName** and **abilityName**, which respectively indicate the bundle name of the target ability and the ability name in the bundle. When ability A needs to start ability B and transfer some data to ability B, it can use Want a carrier to transfer the data.
+
+> **NOTE**
+>
+> The initial APIs of this module are supported since API version 9. Newly added APIs will be marked with a superscript to indicate their earliest API version.
+
+## Modules to Import
+
+```ts
+import Want from '@ohos.app.ability.Want';
+```
+
+## Attributes
+
+**System capability**: SystemCapability.Ability.AbilityBase
+
+| Name | Type | Mandatory| Description |
+| ----------- | -------------------- | ---- | ------------------------------------------------------------ |
+| deviceId | string | No | ID of the device running the ability. |
+| bundleName | string | No | Bundle name of the ability. If both **bundleName** and **abilityName** are specified in a **Want** object, the **Want** object can match a specific ability.|
+| abilityName | string | No | Name of the ability. If both **bundleName** and **abilityName** are specified in a **Want** object, the **Want** object can match a specific ability. The value of **abilityName** must be unique in an application.|
+| uri | string | No | URI information to match. If **uri** is specified in a **Want** object, the **Want** object will match the specified URI information, including **scheme**, **schemeSpecificPart**, **authority**, and **path**.|
+| type | string | No | MIME type, that is, the type of the file to open, for example, **text/xml** and **image/***. For details about the MIME type definition, see https://www.iana.org/assignments/media-types/media-types.xhtml?utm_source=ld246.com. |
+| flags | number | No | How the **Want** object will be handled. By default, numbers are passed in. For details, see [flags](js-apis-ability-wantConstant.md#wantConstant.Flags).|
+| action | string | No | Action to take, such as viewing and sharing application details. In implicit Want, you can define this field and use it together with **uri** or **parameters** to specify the operation to be performed on the data. |
+| parameters | {[key: string]: any} | No | Want parameters in the form of custom key-value (KV) pairs. By default, the following keys are carried:
**ohos.aafwk.callerPid**: PID of the caller.
**ohos.aafwk.param.callerToken**: token of the caller.
**ohos.aafwk.param.callerUid**: UID in [bundleInfo](js-apis-bundle-BundleInfo.md#bundleinfo-1), that is, the application UID in the bundle information. |
+| entities | Array\ | No | Additional category information (such as browser and video player) of the target ability. It is a supplement to **action** in implicit Want and is used to filter ability types. |
+| moduleName | string | No | Module to which the ability belongs.|
+
+**Example**
+
+- Basic usage
+
+ ```ts
+ var want = {
+ "deviceId": "", // An empty deviceId indicates the local device.
+ "bundleName": "com.extreme.test",
+ "abilityName": "MainAbility",
+ "moduleName": "entry" // moduleName is optional.
+ };
+ this.context.startAbility(want, (error) => {
+ // Start an ability explicitly. The bundleName, abilityName, and moduleName parameters work together to uniquely identify an ability.
+ console.log("error.code = " + error.code)
+ })
+ ```
+
+- Data is transferred through user-defined fields. The following data types are supported:
+
+ * String
+ ```ts
+ let want = {
+ bundleName: "com.example.demo",
+ abilityName: "com.example.demo.MainAbility",
+ parameters: {
+ keyForString: "str",
+ },
+ }
+ ```
+ * Number
+ ```ts
+ let want = {
+ bundleName: "com.example.demo",
+ abilityName: "com.example.demo.MainAbility",
+ parameters: {
+ keyForInt: 100,
+ keyForDouble: 99.99,
+ },
+ }
+ ```
+ * Boolean
+ ```ts
+ let want = {
+ bundleName: "com.example.demo",
+ abilityName: "com.example.demo.MainAbility",
+ parameters: {
+ keyForBool: true,
+ },
+ }
+ ```
+ * Object
+ ```ts
+ let want = {
+ bundleName: "com.example.demo",
+ abilityName: "com.example.demo.MainAbility",
+ parameters: {
+ keyForObject: {
+ keyForObjectString: "str",
+ keyForObjectInt: -200,
+ keyForObjectDouble: 35.5,
+ keyForObjectBool: false,
+ },
+ },
+ }
+ ```
+ * Array
+ ```ts
+ let want = {
+ bundleName: "com.example.demo",
+ abilityName: "com.example.demo.MainAbility",
+ parameters: {
+ keyForArrayString: ["str1", "str2", "str3"],
+ keyForArrayInt: [100, 200, 300, 400],
+ keyForArrayDouble: [0.1, 0.2],
+ keyForArrayObject: [{obj1: "aaa"}, {obj2: 100}],
+ },
+ }
+ ```
+ * File descriptor (FD)
+ ```ts
+ import fileio from '@ohos.fileio';
+ var fd;
+ try {
+ fd = fileio.openSync("/data/storage/el2/base/haps/pic.png");
+ } catch(e) {
+ console.log("openSync fail:" + JSON.stringify(e));
+ }
+ var want = {
+ "deviceId": "", // An empty deviceId indicates the local device.
+ "bundleName": "com.extreme.test",
+ "abilityName": "MainAbility",
+ "moduleName": "entry", // moduleName is optional.
+ "parameters": {
+ "keyFd":{"type":"FD", "value":fd}
+ }
+ };
+ this.context.startAbility(want, (error) => {
+ // Start an ability explicitly. The bundleName, abilityName, and moduleName parameters work together to uniquely identify an ability.
+ console.log("error.code = " + error.code)
+ })
+ ```
