POST方法的意外响应代码500

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.

我正在更新旧的项目&到目前为止我还不太了解Android。在项目中，我们有关于产品的评论部分。

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

在发送之前，我们返回的是0(一些错误)和1(成功)。

Below is the code we were using.

下面是我们正在使用的代码。

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"));

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

现在我们已经将返回对象从0/1更改为user对象。

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

是否需要更新JsonObjectRequest到GJSON请求?或者对象也会被JsonObjectRequest解析?

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

我这样问是因为当我执行上面的操作时，会得到下面的错误。

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

Any idea why I am getting this error?

知道我为什么会犯这个错误吗?

Note: This URL is working fine for iPhone application.

注意:这个URL在iPhone应用程序中运行良好。

Edit 1

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.

这是post方法，所以没有完整的url。还有一些参数需要添加，比如?comment= commentmy&userid =123&productId=234。因为它是发布的，所以我没有在实际的url中添加参数。

I have those in another methods

我用另一种方法

@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;
}

Full url is as below.

完整url如下所示。

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

I tested this in Mozilla RESTClient and it works fine.

我在Mozilla RESTClient中测试过，它工作得很好。

Edit 2

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

在进一步检查之后，我发现保护映射 getParams()抛出AuthFailureError{没有被调用。你知道为什么会这样吗? ,>

3 个解决方案

The problem is below.

下面的问题是。

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

It should be

它应该是

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

Copy code from protected Map<String, String> getParams() before final JsonObjectRequest.

从受保护的映射 getParams()中复制代码，直到最终的JsonObjectRequest。 ,>

That's it!!!

就是这样! ! !

Reason is as below.

原因是如下。

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

JsonObjectRequest是一个扩展的JsonRequest，它直接覆盖getBody()方法，因此您的getParam()不会调用，我建议您将StringRequest扩展而不是JsonObjectRequest。

your can check this answer for more details.

你可以查看这个答案以获得更多的细节。

Try to change php file permission to 755.

尝试将php文件权限更改为755。

#3

Actually 500 means Internal server error and this is caused by the Rest-api you are calling and not due to Volley,so check the back-end code.

实际上500表示内部服务器错误，这是由您正在调用的Rest-api引起的，而不是由于截击，所以请检查后端代码。
