android - 在android中将视频上传到facebook

Question

问题:

我的视频没有上传到 Facebook。

问题:

如何将视频上传到 Facebook？

注意:

我可以从我的图库上传图片。

没有 Exceptions被抛出。我觉得线路有问题

params.putString("filename", <selectedviedoPath> )

AsyncFacebookRunner mAsyncFbRunner = new AsyncFacebookRunner(mFacebook);
        Bundle params = new Bundle();
        //convert to byte stream
   **FileInputStream is = new FileInputStream(new File(selectedviedoPath));**
   ByteArrayOutputStream bs = new ByteArrayOutputStream();
        int data = 0;
        while((data = is.read()) != -1)
        bs.write(data);

        is.close();
        byte[] raw = bs.toByteArray();
        bs.close();

        params.putByteArray("video", raw);
        params.putString("filename", <selectedviedoPath> );
        mAsyncFbRunner.request("me/videos", params, "POST", new WallPostListener());

以下是我所做的，现在非常适合在 Facebook 上发布视频。

FacebookVideoPostActivity.java

public class FacebookVideoPostActivity extends Activity {
/** Called when the activity is first created. */

private static Facebook facebook = new Facebook("YOUR_APP_ID"); // App ID For the App
private String permissions[] = {""};  
private String statusString = ""; 
private Button btn1;
private String PATH = "/sdcard/test1.3gp"; // Put Your Video Link Here
private ProgressDialog mDialog ;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    btn1 = (Button) findViewById(R.id.button1);
    mDialog = new ProgressDialog(FacebookVideoPostActivity.this);
    mDialog.setMessage("Posting video...");

    btn1.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            facebook.authorize(FacebookVideoPostActivity.this, new String[]{ "user_photos,publish_checkins,publish_actions,publish_stream"},new DialogListener() {                     
                @Override                     
                public void onComplete(Bundle values) {   
                    postVideoonWall(); 

                }                      
                @Override                     
                public void onFacebookError(FacebookError error) {}                      
                @Override                     
                public void onError(DialogError e) {}                      
                @Override                     
                public void onCancel() {}                 
            });

        }
    });
}

public void postVideoonWall() { 
    mDialog.setMessage("Posting ...");
    mDialog.show();
    new Thread(new Runnable() {
        @Override
        public void run() {

            byte[] data = null;
            InputStream is = null;
            String dataMsg = "This video is posted from bla bla bla App";
            Bundle param;

            try {
                is = new FileInputStream(PATH);
                data = readBytes(is);
                param = new Bundle();
                param.putString("message", dataMsg);
                param.putString("filename", "test1.mp4");
                //param.putString("method", "video.upload"); 
                param.putByteArray("video", data);
                AsyncFacebookRunner mAsyncRunner = new AsyncFacebookRunner(facebook);
                mAsyncRunner.request("me/videos", param, "POST", new SampleUploadListener(), null);
            }
            catch (FileNotFoundException e) {
               e.printStackTrace();
            }
            catch (IOException e) {
               e.printStackTrace();
            }
        }
    }).start();

}


private Handler mPostHandler = new Handler() {
    @Override
    public void handleMessage(Message msg) {
        mDialog.dismiss();
        if(msg.what==0){
            Toast.makeText(getApplicationContext(), "Image Posted on Facebook.", Toast.LENGTH_SHORT).show();
        }
        else if(msg.what==1) {
            Toast.makeText(getApplicationContext(), "Responce error.", Toast.LENGTH_SHORT).show();
        }else if(msg.what==2){
            Toast.makeText(getApplicationContext(), "Facebook error.", Toast.LENGTH_SHORT).show();
        }
    }
};



public byte[] readBytes(InputStream inputStream) throws IOException {
    // This dynamically extends to take the bytes you read.
    ByteArrayOutputStream byteBuffer = new ByteArrayOutputStream();

    // This is storage overwritten on each iteration with bytes.
    int bufferSize = 1024;
    byte[] buffer = new byte[bufferSize];

    // We need to know how may bytes were read to write them to the byteBuffer.
    int len = 0;
    while ((len = inputStream.read(buffer)) != -1) {
        byteBuffer.write(buffer, 0, len);
    }

    // And then we can return your byte array.
    return byteBuffer.toByteArray();
}

public class SampleUploadListener extends BaseRequestListener {
    public void onComplete(final String response, final Object state) {
        try {             
            Log.d("Facebook-Example", "Response: " + response.toString());             
            JSONObject json = Util.parseJson(response);             
            mPostHandler.sendEmptyMessage(0);
            // then post the processed result back to the UI thread             
            // if we do not do this, an runtime exception will be generated             
            // e.g. "CalledFromWrongThreadException: Only the original             
            // thread that created a view hierarchy can touch its views."          
        } catch (JSONException e) {            
            mPostHandler.sendEmptyMessage(1);
            Log.w("Facebook-Example", "JSON Error in response");         
        } catch (FacebookError e) { 
            mPostHandler.sendEmptyMessage(2);
            Log.w("Facebook-Example", "Facebook Error: " + e.getMessage());         
        }     
    }      
    @Override     
    public void onFacebookError(FacebookError e, Object state) {         
        // TODO Auto-generated method stub      
    } 
} 

现在，将 Facebook SDK 集成到您的项目中并进行如下更改:

如下所示从 facebook sdk 更改 Util.java

public static String openUrl(String url, String method, Bundle params)
          throws MalformedURLException, IOException {
        // random string as boundary for multi-part http post
        String strBoundary = "3i2ndDfv2rTHiSisAbouNdArYfORhtTPEefj3q2f";
        String endLine = "\r\n";

        OutputStream os;

// Mo. 919825056129
        // Try to get filename key
          String filename = params.getString("filename");
          // If found
           if (filename != null) {
              // Remove from params
                params.remove("filename");
           }
//===================================================


        if (method.equals("GET")) {
            url = url + "?" + encodeUrl(params);
        }
        Util.logd("Facebook-Util", method + " URL: " + url);
        HttpURLConnection conn =
            (HttpURLConnection) new URL(url).openConnection();
        conn.setRequestProperty("User-Agent", System.getProperties().
                getProperty("http.agent") + " FacebookAndroidSDK");
        if (!method.equals("GET")) {
            Bundle dataparams = new Bundle();
            for (String key : params.keySet()) {
                Object parameter = params.get(key);
                if (parameter instanceof byte[]) {
                    dataparams.putByteArray(key, (byte[])parameter);
                }
            }

            // use method override
            if (!params.containsKey("method")) {
                params.putString("method", method);
            }

            if (params.containsKey("access_token")) {
                String decoded_token =
                    URLDecoder.decode(params.getString("access_token"));
                params.putString("access_token", decoded_token);
            }

            conn.setRequestMethod("POST");
            conn.setRequestProperty(
                    "Content-Type",
                    "multipart/form-data;boundary="+strBoundary);
            conn.setDoOutput(true);
            conn.setDoInput(true);
            conn.setRequestProperty("Connection", "Keep-Alive");
            conn.connect();
            os = new BufferedOutputStream(conn.getOutputStream());

            os.write(("--" + strBoundary +endLine).getBytes());
            os.write((encodePostBody(params, strBoundary)).getBytes());
            os.write((endLine + "--" + strBoundary + endLine).getBytes());

            if (!dataparams.isEmpty()) {

                for (String key: dataparams.keySet()){
    // ADDED By Shreyash For Publish Video 
// sbmmahajan@gmail.com
// Mo. 919825056129
// os.write(("Content-Disposition: form-data; filename=\"" + key + "\"" + endLine).getBytes());
                    os.write(("Content-Disposition: form-data; filename=\"" + ((filename) != null ? filename : key) + "\"" + endLine).getBytes());
                    os.write(("Content-Type: content/unknown" + endLine + endLine).getBytes());
                    os.write(dataparams.getByteArray(key));
                    os.write((endLine + "--" + strBoundary + endLine).getBytes());

                }
            }
            os.flush();
        }

        String response = "";
        try {
            response = read(conn.getInputStream());
        } catch (FileNotFoundException e) {
            // Error Stream contains JSON that we can parse to a FB error
            response = read(conn.getErrorStream());
        }
        return response;
    }

将上面的函数放在那个 Util.Java 中，并注释掉其中可用的相同函数。

现在运行项目。 如果有任何疑问，请告诉我。

享受 :)
