从Facebook Graph-API获取头像

Question

检索照片facebook个人资料的方法不再工作

ImageView user_picture;
 userpicture=(ImageView)findViewById(R.id.userpicture);
 URL img_value = null;
 img_value = new URL("http://graph.facebook.com/"+id+"/picture?type=large");
 Bitmap mIcon1 = BitmapFactory.decodeStream(img_value.openConnection().getInputStream());
userpicture.setImageBitmap(mIcon1);

mIcon1是null

它正常运行，但现在不是，我认为facebook已经改变了一些东西当我检查重定向到另一个URL的URL

http://graph.facebook.com/"id example(2154847)"/picture?Type =large -> https://fbcdn-profile-a.akamaihd.net/hprofile-ak-prn2/t1.0- 1/s200x200/1480603_10201506903424508_71775 13962104534241_n.jpg

编辑解决方案:

 public Bitmap getPhotoFacebook(final String id) {
    Bitmap bitmap=null;
    final String nomimg = "https://graph.facebook.com/"+id+"/picture?type=large";
    URL imageURL = null;
    try {
        imageURL = new URL(nomimg);
    } catch (MalformedURLException e) {
        e.printStackTrace();
    }
    try {
        HttpURLConnection connection = (HttpURLConnection) imageURL.openConnection();
        connection.setDoInput(true);
        connection.setInstanceFollowRedirects( true );
        connection.connect();
        InputStream inputStream = connection.getInputStream();
        //img_value.openConnection().setInstanceFollowRedirects(true).getInputStream()
        bitmap = BitmapFactory.decodeStream(inputStream);
    } catch (IOException e) {
        e.printStackTrace();
    }
    return bitmap;
}

Answer 1

试试这个:

public static Bitmap getFacebookProfilePicture(String userID){
    URL imageURL = new URL("https://graph.facebook.com/" + userID + "/picture?type=large");
    Bitmap bitmap = BitmapFactory.decodeStream(imageUrl.openConnection().getInputStream());
    return bitmap;
}
Bitmap bitmap = getFacebookProfilePicture(userId);

确保您使用的是https而不是http。

试试这个:

img_value.openConnection().setInstanceFollowRedirects(true).getInputStream()
