在我的应用程序中,我必须使用JSON req param发送POST请求,我尝试使用Postman Rest Client创建请求,它工作正常,但不能使用下面的代码。
在Postman req参数中作为原始数据发送,但我不知道如何使用Volley请求发送它。
public Request getHTTPPostReqResponse(String URL, Class mClass, final Map<String, String> params, final String contentType, final String body) {
mResponseListener.requestStarted();
Request mRequest = new GsonRequest(Request.Method.POST, URL, mClass, new Response.Listener<Object>() {
@Override
public void onResponse(Object response) {
mResponseListener.requestCompleted(response);
}
}, new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
mResponseListener.requestEndedWithError(error);
}
}) {
@Override
protected Map<String, String> getParams() {
return params;
}
@Override
public byte[] getBody() throws AuthFailureError {
if (TextUtils.isEmpty(body)){
return super.getBody();
}else {
return body.getBytes();
}
}
@Override
public String getBodyContentType() {
return contentType;
}
@Override
public Map<String, String> getHeaders() throws AuthFailureError {
Map<String, String> params = new HashMap<>();
params.put("Content-Type", contentType);
return params;
}
};
mRequest.setRetryPolicy(new DefaultRetryPolicy(
MY_SOCKET_TIMEOUT_MS,
DefaultRetryPolicy.DEFAULT_MAX_RETRIES,
DefaultRetryPolicy.DEFAULT_BACKOFF_MULT));
return mRequest;
}
请求参数:
{
"nodeId": null,
"userId": null,
"mobileNumber": "993000008",
"emailId": "sharma@gmail.com",
"userProfile": null,
"region": null,
"countryCode": "91",
"password": "pass@123",
"places": [],
"trustedNetwork": [],
"profilePic": null,
"fullName": null,
"longitude": 0.0,
"latitude": 0.0
}

您是否尝试过不同类型的请求,例如String或JsonObject? 并且params的语法不同?
e.g。
Map<String, Object> jsonParams = new ArrayMap<>();
jsonParams.put("nodeId", null);
jsonParams.put("userId", null);
jsonParams.put("mobileNumber", "sharma@gmail.com");
jsonParams.put("userProfile", null);
jsonParams.put("region", null);
jsonParams.put("countryCode", 91);
jsonParams.put("password", pass@123);
jsonParams.put("places", new ArrayList());
jsonParams.put("trustedNetwork", new ArrayList());
jsonParams.put("profilePic", null);
jsonParams.put("fullName", null);
jsonParams.put("longitude", 0.0);
jsonParams.put("latitude", 0.0);
JsonObjectRequest request = new JsonObjectRequest(Request.Method.POST, url, new JSONObject(jsonParams),
new Response.Listener<JSONObject>()
{
@Override
public void onResponse(JSONObject response)
{
mResponseListener.requestCompleted(response);
}
},
new Response.ErrorListener()
{
@Override
public void onErrorResponse(VolleyError error)
{
if (null != error.networkResponse)
{
mResponseListener.requestEndedWithError(error);
}
}
});
另外,请查看this SO question。 希望这有任何帮助。

这是工作代码,你可以试试。我们可以使用JsonObjectRequest来获取原始数据。这里我只展示如何创建在队列中添加的requestObject
WHERE ANY(property in keys(node)
在服务器端PHP我们可以使用
获取数据
String url = MConstant.API_END+"/userLogin";
Map<String, String> params = new HashMap<String, String>();
params.put("email",mEmailView.getText().toString());
params.put("password",mPasswordView.getText().toString());
params.put("api",MConstant.API);
JSONObject objRegData = new JSONObject(params);
JsonObjectRequest jsObjRequest = new JsonObjectRequest
(Request.Method.POST, url, objRegData, new Response.Listener<JSONObject>() {
@Override
public void onResponse(JSONObject response) {
try {
// handle response data
} catch (JSONException e) {
e.printStackTrace();
//pDialog.show();
}
}
}, new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
pDialog.hide();
}
})
{
@Override
public Map<String, String> getHeaders() throws AuthFailureError {
Map<String, String> params = new HashMap<String, String>();
params.put("Content-Type", "application/json");
return params;
}
};
