Question

我已经在图表api中的Facebook页面成功发布了一个Feed。

     try {
                   resObj.put("message","feed from android");
//resObj.put("object_attachment",bitmap);

                } catch (JSONException e) {
                    e.printStackTrace();
                }

                GraphRequest request = GraphRequest.newPostRequest(
                        AccessToken.getCurrentAccessToken(),"363453267193844/photos",resObj,
                        new GraphRequest.Callback() {
                            @Override
                            public void onCompleted(GraphResponse graphResponse) {
                                Log.i(TAG,"post page response::"+graphResponse);

                            }
                        }
                    );

                request.executeAsync();

但是，我无法将图片发布到脸谱页面。问题是我无法在Graph Api中发布的Json数据中找到图像附件的密钥。

来自facebook的失败回复是

{Response:  responseCode: 400, graphObject: null, error: {HttpStatus: 400, errorCode: 324, errorType: OAuthException, errorMessage: (#324) Requires upload file}}

Answer 1

最后，最后，我能够将图像发布到Facebook页面。这就是我发布照片的方式。

  Bundle bundle=new Bundle();
        bundle.putByteArray("object_attachment",byteArray);// object attachment must be either byteArray or bitmap image
        bundle.putString("message","some message here");

        GraphRequest graphRequest=new GraphRequest(AccessToken.getCurrentAccessToken(),
                "{page_id}/photos",
                bundle,
                HttpMethod.POST,
                new GraphRequest.Callback() {

                    @Override
                    public void onCompleted(GraphResponse graphResponse) {

                      Log.i("post page response::" + graphResponse);

                }
        );
        graphRequest.executeAsync();

1。）确保您拥有publish_pages权限的页面访问令牌，可用于发布新照片。

2。）来自docs。请注意，您在通话中的pageid之前没有“/”。

将照片发布到Facebook有两种不同的方式：

1：将照片作为multipart / form-data附加。对象的名称   没关系，但从历史上看，人们已经将源作为   照片的参数名称。这是如何工作取决于您的SDK   碰巧用来做帖子。

2：使用以下内容发布，使用互联网上已有的照片   url参数：
Bundle params = new Bundle();
params.putString("url", "{image-url}");
/* make the API call */
new Request(
    session,
    "/{page-id}/photos",
    params,
    HttpMethod.POST,
    new Request.Callback() {
        public void onCompleted(Response response) {
            /* handle the result */
        }
    }
).executeAsync();
无法在同一图表API中发布多张照片调用

3。）示例==＆gt;

尝试这样，即发布照片的byteArrayStream

postParams = new Bundle();

            postParams.putString("message", "feed from android");
            postParams.putBoolean("published",true);
            String pageID = "363453267193844";

            //Post to the page as the page user
            ByteArrayOutputStream stream = new ByteArrayOutputStream();
            <YOURBITMAPPHOTOHANDLE>.compress(Bitmap.CompressFormat.PNG, 100, stream);
            byte[] byteArray = stream.toByteArray();
            postParams.putByteArray("source", byteArray);

            postParams.putString("access_token", "your_page_access_token");

         /* make the API call */
            new Request(
                    sessionInstance,
                    "/" + pageID + "/photos",
                    postParams,
                    HttpMethod.POST,
                    new Request.Callback() {
                        public void onCompleted(Response response) {
                            //An error occurred during posting to facebook
                            FacebookRequestError error = response.getError();
                            if (error != null) {
                                isPostingError = true;
                                postingErrorMessage = error.getErrorUserMessage();

                            } else {
                                isPostingError = false;
                            }

                        }


                    }
            ). executeAsync();
