意外的响应code 500的POST方法 [英] Unexpected response code 500 for POST method

问题描述

我做的老项目和放大器的最新情况;我没有安卓的多的知识，现在。在项目中，我们对产品的注释部分。

I am doing an update on the old project & I don't have much knowledge of Android as of now. In project we have Comments section on product.

有关早期发送后评论我们已经恢复为0（某些错误）及1（成功）。

For comment after sending earlier we had return as 0 (some error) & 1 (success).

下面是我们使用了code。

Below is the code we were using.

final JsonObjectRequest jsonObjectRequest = new JsonObjectRequest(
    Method.POST,
    act.getString(R.string.CommentForUserURL),
    null, new Response.Listener<JSONObject>() {

    @Override
    public void onResponse(
            JSONObject response) {

        Log.d("response done", "done===" + response);

        mloading.setVisibility(View.GONE);
        if (response != null) {
            Comment obj = new Comment();
            JSONObject jsonObject = response;
            try {
                obj.setComment(jsonObject
                        .getString("Comment"));

现在，我们已经改变了返回的对象从0/1到用户对象。

Now we have changed the return object from 0/1 to user object.

这是否需要需要更新JsonObjectRequest到GJSON要求？或者，对象也将被解析与JsonObjectRequest？

Does this need need to update JsonObjectRequest to GJSON request? Or object will also get parsed with JsonObjectRequest?

我问，因为当我执行上面的，我得到如下错误。

I am asking because when I execute above, I get error as below.

01-25 12:30:21.754: E/Volley(16487): [10114] BasicNetwork.performRequest: 
Unexpected response code 500 for 
http://new.souqalharim.com/add/CommentForMerchant

任何想法，为什么我收到此错误？

Any idea why I am getting this error?

注：这个URL工作正常的iPhone应用程序的

这是POST方法，所以完整的URL是不存在的。很少有多个参数添加赞评论= MyComment和放大器;用户id = 123＆安培; productId参数= 234。由于这是后我没有在实际的URL添加参数。

This is post method, so full url is not there. There are few more parameters to add like ?comment=MyComment&userId=123&productId=234. As it is post I am not adding parameters in actual url.

我有那些在另外一个方法

I have those in another methods

@Override
protected Map<String, String> getParams()
        throws AuthFailureError {
    Map<String, String> params = new HashMap<String, String>();
    params.put("productId", productId.toString());
    params.put("userId",
            mSessionManager.getUserCode().toString());
    params.put("comment", GlobalFunctions
            .EncodeParameter(med_comments
                    .getText().toString()));



    return params;
}

完整的URL是如下。

Full url is as below.

的http://new.souqalharim.com/add/CommentForUser?productId=325&userId=5&comment=abcd

我在Mozilla RESTClient测试这一点，它工作正常。

I tested this in Mozilla RESTClient and it works fine.

进一步检查后，我发现保护地图＆LT;字符串，字符串＆GT; getParams（）方法抛出AuthFailureError {是没有得到调用。任何想法，为什么会这样？

After checking further I found protected Map<String, String> getParams() throws AuthFailureError { is not getting called. Any idea why this is happening?

推荐答案

现在的问题是如下：

final JsonObjectRequest jsonObjectRequest = new JsonObjectRequest(
    Method.POST,
    act.getString(R.string.CommentForUserURL),
    null, new Response.Listener<JSONObject>() {
    ^^^^

这应该是

final JsonObjectRequest jsonObjectRequest = new JsonObjectRequest(
    Method.POST,
    act.getString(R.string.CommentForUserURL),
    new JSONObject(params), new Response.Listener<JSONObject>() {
    ^^^^^^^^^^^^^^^^^^^^^^

从

复制code保护地图＆LT;字符串，字符串＆GT; getParams（）方法在最后JsonObjectRequest 。

这就是它！

原因如下。

在 JsonObjectRequest 延长<一个href="https://android.googlesource.com/platform/frameworks/volley/+/master/src/com/android/volley/toolbox/JsonRequest.java"相对=nofollow> JsonRequest 其覆盖 getBody（）方法直接，让您的 getParam（）永远不会调用，我建议您延长 StringRequest 而不是JsonObjectRequest。

The JsonObjectRequest is extended JsonRequest which override getBody() method directly, so your getParam() would never invoke, I recommend you extend StringRequest instead of JsonObjectRequest.
