使用图形 API ，如何检索评论和评论回复的图像?

Question

>我正在创建一个Android应用程序，该应用程序具有使用Graph API检索Facebook帖子的功能。

我的问题
我的问题是，收到的JSON缺少以下字段：

• 附有注释
  的图像的网址
• 对评论的回复
• 只有没有。 的喜欢可用。无反应列表
• 对于包含多张图片的帖子，full_picture字段只包含一张图片的链接。其他图像的链接在哪里？

我用/me/posts来获取帖子。

为什么我无法获得上述详细信息？

采取的步骤我
搜索了 Stackoverflow，但答案只提到了如何获取个人通信的图像和回复(通过使用评论 ID)，但没有参考如何与从"/me/posts"收到的 JSON 一起获取它。(所以，这不是重复的!!!)

我的查询

• 为什么我无法获得上述详细信息？
获取
• 评论的图像，回复，捆绑包中父帖子和帖子反应的所有图像的url的方法是什么。(这与"/me/posts"的 JSON 一起没有为每个评论运行/comment请求？

我的代码

编写执行图形查询的代码

login_button.setReadPermissions(Arrays.asList(
"public_profile", "email", "user_birthday", "user_friends","user_posts", "user_status")); // Setting permissions
Bundle params = new Bundle();
params.putString("fields", "message,created_time,id,full_picture,status_type,source,comments.summary(true),likes.summary(true)");
params.putString("limit", "100");
new GraphRequest( loginResult.getAccessToken(), "/me/posts", params, HttpMethod.GET,
new GraphRequest.Callback() {
public void onCompleted(GraphResponse response)  {
/* handle the result */
try {
EditText postsText = (EditText) findViewById(R.id.postText);
String res = response.toString();
res = res.replaceAll("\{Response:\s*\w*\W*\s*[0-9]*\W*\w*:", "");
res = res.replaceAll("\,\s*error:\s*null\W*\s*","");
postsText.setText(res);
writeToFile(res,"response");
}
catch (Exception e) {
e.printStackTrace();
}
}
}
).executeAsync();

}
@Override
public void onCancel() {
txtstatus.setText("Login canceled");
}
@Override
public void onError(FacebookException error) {
txtstatus.setText("Login failed"+error.getMessage());
}
});

好吧，关于"反应列表"，这仅适用于页面所有者(从 2018 年 2 月开始)。
