在Facebook SDK 4（Android）中创建请求 [英] Create a Request in Facebook SDK 4 (Android)

问题描述

据我所知，Facebook SDK v4不再使用会话，但是我读了他们的Graph API文档，会话仍然用于创建请求

https://developers.facebook.com/docs/ graph-api / using-graph-api / v2.3

  / *使API调用* / 
 new Request（
 session，
/ me，
 null，
 HttpMethod.GET，
 new Request.Callback（）{
 public void onCompleted（响应响应）{
 / *处理结果* / 
} 
} 
）.executeAsync（）; 
  

令我困惑的是，如何获取请求的会话？使用Facebook Graph API获取用户个人资料数据的最新示例？

任何建议都不胜感激。

解决方案

在Facebook开发人员页面上发布了一个更新日志和升级文章。在你的情况下，这将是一个选项：

  GraphRequest request = GraphRequest.newMeRequest（accessToken，new GraphRequest.GraphJSONObjectCallback（）{
 @Override 
 public void onCompleted（JSONObject user，GraphResponse response）{
 / *处理结果* / 
} 
}）executeAsync（）; 
  

顺便说一句，他们指定：

< blockquote>

默认情况下，newMeRequest方法从用户对象获取默认字段。如果您需要任何其他字段，或者由于性能原因希望减少响应有效负载，则可以添加字段参数并请求特定字段。

例如：

  GraphRequest request = GraphRequest.newMeRequest（
 accessToken，
 new GraphRequest.GraphJSONObjectCallback （）{
 @Override 
 public void onCompleted（
 JSONObject对象，
 GraphResponse响应）{
 //应用程序代码
} 
} ）; 
 Bundle parameters = new Bundle（）; 
 parameters.putString（fields，id，name，link）; 
 request.setParameters（parameters）; 
 request.executeAsync（）; 
  

我希望我的答案可以帮助你，这是我在stackoverflow中的第一个答案。问候。

参考： Facebook Android SDK升级

As I understand, Facebook SDK v4 doesn't use the Session anymore, but I read in their Graph API document, the session is still used to create the Request

https://developers.facebook.com/docs/graph-api/using-graph-api/v2.3

/* make the API call */
new Request(
    session,
    "/me",
    null,
    HttpMethod.GET,
    new Request.Callback() {
        public void onCompleted(Response response) {
            /* handle the result */
        }
    }
).executeAsync();

It's confusing me, and how can I get the session for Request? Any latest example to get the user profile data by using Facebook Graph API?

Any advice is appreciated.

解决方案

On facebook developers' page is published a changelog and upgrade post. In your case this would be an option:

GraphRequest request = GraphRequest.newMeRequest(accessToken, new GraphRequest.GraphJSONObjectCallback() {
            @Override
            public void onCompleted(JSONObject user, GraphResponse response) {
                /* handle the result */
            }
    }).executeAsync();

By the way, they specify this:

By default a newMeRequest method fetches default fields from a user object. If you need any additional fields, or want to reduce the response payload for performance reasons, you can add a fields parameter and request specific fields.

For example:

GraphRequest request = GraphRequest.newMeRequest(
    accessToken,
    new GraphRequest.GraphJSONObjectCallback() {
        @Override
        public void onCompleted(
               JSONObject object,
               GraphResponse response) {
            // Application code
        }
    });
Bundle parameters = new Bundle();
parameters.putString("fields", "id,name,link");
request.setParameters(parameters);
request.executeAsync();

I hope my answer helps you, being this one my first answer in stackoverflow. Greetings.
