android中httppost发送的参数在服务器上被作为null插入

android中httppost发送的参数在服务器上被作为null插入,android,android-volley,google-cloud-endpoints,Android,Android Volley,Google Cloud Endpoints,我试图使用截取功能将参数发送到服务器,即将数据发送到google云端点,但在服务器上,插入了null值。我在邮递员身上也试过了 如果我使用x-www-form-urlencoded,我在postman和android中都会遇到错误: { "error": { "errors": [ { "domain": "global", "reason": "parseError", "message": "Th

我试图使用截取功能将参数发送到服务器,即将数据发送到google云端点,但在服务器上,插入了null值。我在邮递员身上也试过了

如果我使用x-www-form-urlencoded,我在postman和android中都会遇到错误:

{
"error": {
    "errors": [
        {
            "domain": "global",
            "reason": "parseError",
            "message": "This API does not support parsing form-encoded input."
        }
    ],
    "code": 400,
    "message": "This API does not support parsing form-encoded input."
}
}

如果我使用表单数据,我会在邮递员中得到我需要的响应。同样,我使用内容类型作为表单数据。但在服务器的数据库中插入了空值

我的方法是:

 RequestQueue queue = Volley.newRequestQueue(MainActivity.this);
    // "TAG" used to cancel the request
    String url = "My URL";

    final ProgressDialog pDialog = new ProgressDialog(MainActivity.this);
    pDialog.setMessage("Registering...");
    pDialog.show();

    StringRequest mstringrequest = new StringRequest(Request.Method.DEPRECATED_GET_OR_POST, url, new Response.Listener<String>() {
        @Override
        public void onResponse(String response) {
            // mPostCommentResponse.requestCompleted();
            Log.e("TAG", "Service--o/p-" + response);
            pDialog.dismiss();
        }
    }, new Response.ErrorListener() {
        @Override
        public void onErrorResponse(VolleyError error) {
            // mPostCommentResponse.requestEndedWithError(error);
            Log.e("TAG", "Service--i/p-" + error);
            pDialog.dismiss();
        }
    }) {
        @Override
        protected Map<String, String> getParams() {
            Map<String, String> params = new HashMap<String, String>();
            params.put("displayEmail", "prachi@gmail.com");
            params.put("displayName", "prachi");
            return params;
        }

        @Override
        public Map<String, String> getHeaders() throws AuthFailureError {
            Map<String, String> params = new HashMap<String, String>();


            params.put("Content-Type", "form-data");
            params.put("Content-Disposition", "form-data");


            return params;
        }
    };

    mstringrequest.setRetryPolicy(new DefaultRetryPolicy(
            60000,
            DefaultRetryPolicy.DEFAULT_MAX_RETRIES,
            DefaultRetryPolicy.DEFAULT_BACKOFF_MULT));


    queue.add(mstringrequest);
RequestQueue=Volley.newRequestQueue(MainActivity.this);
//“标签”用于取消请求
String url=“我的url”;
final ProgressDialog pDialog=新建ProgressDialog(MainActivity.this);
pDialog.setMessage(“注册…”);
pDialog.show();
StringRequest mstringrequest=新建StringRequest(Request.Method.DEPRECATED_GET_或_POST、url、new Response.Listener(){
@凌驾
公共void onResponse(字符串响应){
//mPostCommentResponse.requestCompleted();
Log.e(“标签”,“服务--o/p-”+响应);
pDialog.disclose();
}
},new Response.ErrorListener(){
@凌驾
公共无效onErrorResponse(截击错误){
//mPostCommentResponse.requestEndedWithError(错误);
Log.e(“标签”,“服务--i/p-”+错误);
pDialog.disclose();
}
}) {
@凌驾
受保护的映射getParams(){
Map params=新的HashMap();
参数put(“显示电子邮件”prachi@gmail.com");
参数put(“显示名称”、“普拉奇”);
返回参数;
}
@凌驾
公共映射getHeaders()引发AuthFailureError{
Map params=新的HashMap();
参数put(“内容类型”、“表单数据”);
参数put(“内容处理”、“表单数据”);
返回参数;
}
};
mstringrequest.setRetryPolicy(新的DefaultRetryPolicy(
60000,
DefaultRetryPolicy.DEFAULT\u最大重试次数,
DefaultRetryPolicy.DEFAULT_BACKOFF_MULT));
添加(mstringrequest);
请帮忙。。我错在哪里

我找到了解决办法

 RequestQueue queue = Volley.newRequestQueue(LoginActivity.this);
    final ProgressDialog pDialog = new ProgressDialog(LoginActivity.this);
pDialog.setMessage("Logging In...");
    pDialog.show();

    JsonObjectRequest jsonObjReq = new JsonObjectRequest(Request.Method.POST, Constants.URL_Login, Jsonobj,
            new Response.Listener<JSONObject>() {
                @Override
                public void onResponse(JSONObject response) {
                    // mPostCommentResponse.requestCompleted();
                    Log.e(TAG, "Service--o/p-" + response);
                    pDialog.dismiss();
                }
            }, new Response.ErrorListener() {
        @Override
        public void onErrorResponse(VolleyError error) {
            // mPostCommentResponse.requestEndedWithError(error);
            Log.e("TAG", "Service--i/p-" + error);
            pDialog.dismiss();

        }
    });
    jsonObjReq.setRetryPolicy(new DefaultRetryPolicy(
            60000,
            DefaultRetryPolicy.DEFAULT_MAX_RETRIES,
            DefaultRetryPolicy.DEFAULT_BACKOFF_MULT));


    queue.add(jsonObjReq);
RequestQueue queue=Volley.newRequestQueue(LoginActivity.this);

设置消息(“登录…”);
pDialog.show();

新的Response.Listener(){

尝试使用
“内容类型”、“应用程序/json”
并发送
json
编码数据。我也尝试过。但仍然不起作用:(我们使用的是带有数据存储的Google端点,我们想发送post数据,而不是json encodedOk,我是一个猜测。一个可怕的猜测。
