使用Android Volley发送带有正文的JSON帖子 [英] Sending JSON Post with Body using Android Volley

问题描述

我正在尝试使用Android Volley库发送JSON Post请求，但是我似乎没有正确获取JSON的主体，并且在Web服务器上得到了未定义的主体参数.我需要json的参数主体为单个对象"name = someVal& comment = someOtherVal".名称和注释是键，someVal和someOtherVal是值.

I am trying to send a JSON Post request using Android Volley library but I dont seem to get the body of the json right and I get undefined body parameters on my web server. I need the json's parameters body to be a single object "name=someVal&comment=someOtherVal". name and comment are the keys and someVal and someOtherVal are the values.

String spreadsheetID = "1111111-11111N92RT9h-11111111111111111111111111111";
String url = "https://script.google.com/macros/s/" + spreadsheetID + "/exec";
// Instantiate the RequestQueue.
RequestQueue queue = Volley.newRequestQueue(this);

// Request a string response from the provided URL.
JsonObjectRequest jsonObjReq = new JsonObjectRequest(Request.Method.POST,
        url, null,
        new Response.Listener<JSONObject>() {

@Override
public void onResponse(JSONObject response) {
    Log.d("JSONPost", response.toString());
    //pDialog.hide();
}
        }, new Response.ErrorListener() {

    @Override
    public void onErrorResponse(VolleyError error) {
        VolleyLog.d("JSONPost", "Error: " + error.getMessage());
        //pDialog.hide();
    }
}) {

    @Override
    protected Map<String, String> getParams() {
        Map<String, String> params = new HashMap<String, String>();
        params.put("name=someVal&comment=someOtherVal");
        //params.put("comment", "someOtherVal");
        return params;
    }
};
// Add the request to the RequestQueue.
queue.add(jsonObjReq);

}

我也在上面的代码中尝试过，但是没有运气:

I also tried this in the above code but no luck:

params.put("comment", "someOtherVal");
params.put("name", "someVal");

推荐答案

尝试放置

Map<String, String> params = new HashMap<String, String>();
params.put("comment", "someOtherVal");
params.put("name", "someVal");

在JsonObjectRequest jsonObjReq ...之前，并将null值更改为

before JsonObjectRequest jsonObjReq ... and change the null value by

new JsonObject(params)

因此您的代码将是

Map<String, String> params = new HashMap<String, String>();
    params.put("comment", "someOtherVal");
    params.put("name", "someVal");

JsonObjectRequest jsonObjReq = new JsonObjectRequest(Request.Method.POST,
        url, new JsonObject(params),
        new Response.Listener<JSONObject>() {

@Override
public void onResponse(JSONObject response) {
    Log.d("JSONPost", response.toString());
    //pDialog.hide();
}
        }, new Response.ErrorListener() {

    @Override
    public void onErrorResponse(VolleyError error) {
        VolleyLog.d("JSONPost", "Error: " + error.getMessage());
        //pDialog.hide();
    }
})
