GoogleCloudMessaging未经授权错误401（Android作为服务器）

Question

I am trying to send message to device using GCM .As a special case I am using android device as my third party server. 我正在尝试使用GCM向设备发送消息。在特殊情况下，我将android设备用作第三方服务器。 I have added following code but I am getting "Unauthorized Error 401" . 我添加了以下代码，但出现“未经授权的错误401”。 Here I am simply trying to replicate php server code in android . 在这里，我只是想在android中复制php服务器代码。

JAVA CODE WHICH IS NOT WORKING - RETURNING ERROR 401 . 无法工作的JAVA代码-返回错误401。

    // HTTP POST request
private void sendPost() throws JSONException, ClientProtocolException, IOException{
    final String SERVICE_URL = "https://android.googleapis.com/gcm/send";
    InputStream inputStream = null;
    String result = "";
    final String REGISTRATION_ID ="APA91bHH4iNCFdWUIXSHRXV3hsBeF8IU0ZElts9AXaHItDfRdRld-kwkVx69EFYZePPuLOW1hTkUCmAwyTeGdoirr25KJ3RG1AikGbBzsvqaPCLLz9YYCwPDuB6xUupVKmllNoTn2v0BRTTkC6OS_i8zerATtBP3gg" ;
    final String API_KEY = "AIzaSyARQTvQ5pRYEbW-9V98uDHNnn10Rwffx18";
    HttpClient httpclient = new DefaultHttpClient();

    HttpPost httpPost = new HttpPost(SERVICE_URL);
    int iresponse; 
    sds  
            String base64EncodedCredentials = Base64.encodeToString(API_KEY.getBytes("UTF-8"), Base64.NO_WRAP);
    // inform the server about the type of the content
    httpPost.addHeader("Authorization", "key=" + base64EncodedCredentials);

    String json = "";

    JSONObject jsonObject = new JSONObject();
    jsonObject.accumulate("registration_ids", REGISTRATION_ID);

    // convert JSONObject to JSON to String
    json = jsonObject.toString();

    // set json to StringEntity
    StringEntity se = new StringEntity(json);

    // set httpPost Entity
    httpPost.setEntity(se);
    httpPost.setHeader("Accept", "application/json");
    httpPost.setHeader("Content-type", "application/json");

    // Execute POST request to the given URL
    HttpResponse httpResponse = httpclient.execute(httpPost);
    iresponse = httpResponse.getStatusLine().getStatusCode();
    System.out.println(iresponse);
    // receive response as inputStream
    inputStream = httpResponse.getEntity().getContent();

    // convert inputstream to string
    if(inputStream != null)
    result = convertInputStreamToString(inputStream);

    System.out.println(result);

}

    private static String convertInputStreamToString(InputStream inputStream) throws IOException{
    BufferedReader bufferedReader = new BufferedReader( new InputStreamReader(inputStream));
    String line = "";
    String result = "";
    while((line = bufferedReader.readLine()) != null)
        result += line;

    inputStream.close();
    return result;

WORKING PHP CODE 工作PHP代码

<?php
$api_key = "AIzaSyARQTvQ5pRYEbW-9V98uDHNnn10Rwffx18";

$headers = array(
'Authorization: key=' . $api_key,
'Content-Type: application/json');
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt( $ch, CURLOPT_POST, true );
curl_setopt( $ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt( $ch, CURLOPT_RETURNTRANSFER, true );

curl_setopt( $ch, CURLOPT_SSL_VERIFYPEER , false );
curl_setopt( $ch, CURLOPT_SSL_VERIFYHOST , false );

curl_setopt( $ch, CURLOPT_POSTFIELDS, json_encode( $fields ) );
$result = curl_exec($ch);
curl_close($ch);

echo $result;
?>
</body>
</html>

In the above Java code API_KEY is browser key and REGISTRATION_IDis the id returned by Google Cloud Server . 在上面的Java代码中，API_KEY是浏览器密钥，REGISTRATION_ID是Google Cloud Server返回的ID。 Same thing is tested using server key . 使用服务器密钥测试相同的事物。

Two problems which i found in your code is 我在您的代码中发现的两个问题是
1. you are sending an encoded API key 1.您正在发送编码的API密钥
2. you are posting a form data in key value pair , need to post json data 2.您要在键值对中发布表单数据，需要发布json数据

Below is the modified code which is working fine 下面是修改好的代码，可以正常工作

private void sendPost() throws Exception {

    //Below is a good tutorial , how to post json data
    //http://hmkcode.com/android-send-json-data-to-server/

    final String REGISTRATION_ID ="APA91bHH4iNCFdWUIXSHRXV3hsBeF8IU0ZElts9AXaHItDfRdRld-kwkVx69EFYZePPuLOW1hTkUCmAwyTeGdoirr25KJ3RG1AikGbBzsvqaPCLLz9YYCwPDuB6xUupVKmllNoTn2v0BRTTkC6OS_i8zerATtBP3gg" ;
    final String API_KEY = "AIzaSyARQTvQ5pRYEbW-9V98uDHNnn10Rwffx18";



    String url = "https://android.googleapis.com/gcm/send";
    HttpClient client = new DefaultHttpClient();
    HttpPost post = new HttpPost(url);
    JSONObject mainData = new JSONObject();
    try {
        JSONObject data = new JSONObject();
        data.putOpt("message1", "test msg");
        data.putOpt("message2", "testing..................");
        JSONArray regIds = new JSONArray();
        regIds.put(REGISTRATION_ID);
        mainData.put("registration_ids", regIds);
        mainData.put("data", data);
        Log.e("test","Json data="+mainData.toString());
    } catch (JSONException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

    StringEntity se = new StringEntity(mainData.toString());
    post.setEntity(se);
    post.addHeader("Authorization", "key="+API_KEY);
    post.addHeader("Content-Type", "application/json");
    HttpResponse response = client.execute(post);
    Log.e("test" ,
            "response code ="+Integer.toString(response.getStatusLine().getStatusCode()));
    BufferedReader rd = new BufferedReader(
            new InputStreamReader(response.getEntity().getContent()));
    StringBuffer result = new StringBuffer();
    String line = "";
    while ((line = rd.readLine()) != null)
    {
        result.append(line);
    }
    Log.e("test","response is"+result.toString());
}

I have resolved this problem using following code : 我已经使用以下代码解决了这个问题：
