问题描述

编辑:Anwser在文章最后

我想获得一个Facebook用户的资料图片得益于内置的Facebook SDK的功能 请求()

我使用的是 / ME /图片 调用来获取个人资料图片,并将其转换成 位图

呼叫工作正常,但我不知道该如何跨preT和解析从Facebook返回的结果

下面是 JSON ,我得到的:

{FACEBOOK_NON_JSON_RESULT: " \u0000\u0010JFIF\u0000\u0001\u0002\u0000\u0000\u0001\u0000\u0001\u0000\u0000 \u0000\u0004*\u0000 \u0000C\u0000\u0006\u0004\u0005\u0006\u0005\u0004\u0006\u0006\u0005\u0006\u0007\u0007\u0006\b"}

我想这应该是重新presenting资料图片,但我不知道现在该怎么办这个问题。

如果有人能告诉我,无论怎样去code,它转换为位图或什么样的数据是,我将不胜感激。

注:我不希望使用任何其他功能比要求(),像德codeStream()或AsyncTask的


下面就是答案:

在做一个新的请求()则需要将重定向参数添加到

 捆绑PARAMS =新包();
params.putBoolean(重定向,假);
 

这将返回正确的图片网址:

  {
数据:{
      is_silhouette:假的,
      "url":"https:\/\/fbcdn-profile-a.akamaihd.net\/hprofile-ak-xpa1\/v\/t1.0-1\/p100x100\/10312434_10152395442477210_2933994167675146084_n.jpg?oh=f3c8cb920c97fcfa4dc5e17462445cbf&oe=54404A3A&__gda__=1412730795_5f288e34e5f6e63cb1c3791dcb142880"
   }
}
 

解决方案

  GraphRequest picGraphRequest = GraphRequest.newGraphPathRequest(loginResult.getAccessToken(),/我/图片,​​新GraphRequest.Callback (){
        @覆盖
        公共无效onCompleted(GraphResponse graphResponse){
            Log.d(TAG,graphResponse.getJSONObject()的toString());
        }
    });
    捆绑picParameters =新包();
    picParameters.putString(宽度,9999);
    picParameters.putString(重定向,假);
    picGraphRequest.setParameters(picParameters);
    picGraphRequest.executeAsync();
 

背后保持宽度为9999的想法是让全分辨率图像。

EDIT: Anwser at the end of this post.

I am trying to get a Facebook user's profile picture thanks to the inbuilt Facebook SDK's function Request().

I am using a /me/picture call to get the profile picture and convert it into a Bitmap.

The call is working fine but I don't know how to interpret and parse the result returned from Facebook

Here is the JSON that I get:

{"FACEBOOK_NON_JSON_RESULT" : "����\u0000\u0010JFIF\u0000\u0001\u0002\u0000\u0000\u0001\u0000\u0001\u0000\u0000��\u0000\u0004*\u0000��\u0000C\u0000\u0006\u0004\u0005\u0006\u0005\u0004\u0006\u0006\u0005\u0006\u0007\u0007\u0006\b"}

I think this should be representing the profile picture but I don't know what to do with this now.

If somebody could tell me either how to decode it, convert it to a Bitmap or what kind of data it is, I would be grateful.

NOTES: I don't want to use any other function than Request(), like DecodeStream() or an AsyncTask


Here is the answer:

When making a new Request() you need to add the "redirect" parameter to false:

Bundle params = new Bundle();
params.putBoolean("redirect", false);

This will return the correct picture URL:

{
"data":{
      "is_silhouette":false,
      "url":"https:\/\/fbcdn-profile-a.akamaihd.net\/hprofile-ak-xpa1\/v\/t1.0-1\/p100x100\/10312434_10152395442477210_2933994167675146084_n.jpg?oh=f3c8cb920c97fcfa4dc5e17462445cbf&oe=54404A3A&__gda__=1412730795_5f288e34e5f6e63cb1c3791dcb142880"
   }
}
解决方案
GraphRequest picGraphRequest = GraphRequest.newGraphPathRequest(loginResult.getAccessToken(), "/me/picture", new GraphRequest.Callback() {
        @Override
        public void onCompleted(GraphResponse graphResponse) {
            Log.d(TAG, graphResponse.getJSONObject().toString());
        }
    });
    Bundle picParameters = new Bundle();
    picParameters.putString("width", "9999");
    picParameters.putString("redirect", "false");
    picGraphRequest.setParameters(picParameters);
    picGraphRequest.executeAsync();

The idea behind keeping width as 9999 is to get the full resolution image.
