GraphRequest
Đã có phiên bản mới hơn của lớp này. Hãy kiểm tra phiên bản mới nhất.

A single request to be sent to the Facebook Platform through the Graph API. The Request class provides functionality relating to serializing and deserializing requests and responses, making calls in batches (with a single round-trip to the service) and making calls asynchronously.

The particular service endpoint that a request targets is determined by a graph path (see the setGraphPath.setGraphPath(String) method).

A Request can be executed either anonymously or representing an authenticated user. In the former case, no AccessToken needs to be specified, while in the latter, an AccessToken must be provided. If requests are executed in a batch, a Facebook application ID must be associated with the batch, either by setting the application ID in the AndroidManifest.xml or via FacebookSdk or by calling the setDefaultBatchApplicationId.setDefaultBatchApplicationId(String) method.

After completion of a request, the AccessToken, if not null and taken from AccessTokenManager, will be checked to determine if its Facebook access token needs to be extended; if so, a request to extend it will be issued in the background.

GraphRequest()

Constructs a request without an access token, graph path, or any other parameters.

public GraphRequest()
GraphRequest(AccessToken, String)

Constructs a request with an access token to retrieve a particular graph path. An access token need not be provided, in which case the request is sent without an access token and thus is not executed in the context of any particular user. Only certain graph requests can be expected to succeed in this case.

public GraphRequest(AccessToken accessToken, String graphPath)
Thông sốMô tả
accessTokenThe access token to use, or null
graphPathThe graph path to retrieve
GraphRequest(AccessToken, String, Bundle, HttpMethod)

Constructs a request with a specific AccessToken, graph path, parameters, and HTTP method. An access token need not be provided, in which case the request is sent without an access token and thus is not executed in the context of any particular user. Only certain graph requests can be expected to succeed in this case.

Depending on the httpMethod parameter, the object at the graph path may be retrieved, created, or deleted.

newCustomAudienceThirdPartyIdRequest(AccessToken, Context, String, Callback)

Creates a new Request configured to retrieve an App User ID for the app's Facebook user. Callers will send this ID back to their own servers, collect up a set to create a Facebook Custom Audience with, and then use the resultant Custom Audience to target ads.

The GraphObject in the response will include a "custom_audience_third_party_id" property, with the value being the ID retrieved. This ID is an encrypted encoding of the Facebook user's ID and the invoking Facebook app ID. Multiple calls with the same user will return different IDs, thus these IDs cannot be used to correlate behavior across devices or applications, and are only meaningful when sent back to Facebook for creating Custom Audiences.

The ID retrieved represents the Facebook user identified in the following way: if the specified access token (or active access token if null) is valid, the ID will represent the user associated with the active access token; otherwise the ID will represent the user logged into the native Facebook app on the device. A null ID will be provided into the callback if a) there is no native Facebook app, b) no one is logged into it, or c) the app has previously called FacebookSdk.setLimitEventAndDataUsage(android.content.Context, boolean) ;} with true for this user. You must call this method from a background thread for it to work properly.

Thông sốMô tả
accessTokenThe access token to issue the Request on, or null If there is no logged-in Facebook user, null is the expected choice.
contextThe Application context from which the app ID will be pulled, and from which the 'attribution ID' for the Facebook user is determined. If there has been no app ID set, an exception will be thrown.
applicationIdExplicitly specified Facebook App ID. If null, the application ID from the access token will be used, if any; if not, the application ID from metadata will be used.
callbackA callback that will be called when the request is completed to handle success or error conditions. The GraphObject in the Response will contain a "custom_audience_third_party_id" property that represents the user as described above.
Returns
A Request that is ready to execute
