【问题描述】:
我正在尝试连接 API url="api adress",它接受两种标头类型 application/json 以响应 json 和 application/xml 以响应 xml。我需要用 json 参数打 JSON,响应也将是 json 格式。使用带有 JsonObjectRequest 设置标头的 android volley Post 请求使用 getHeaders 连接到服务器,但 getParams 设置参数不起作用。
RequestQueue queue = Volley.newRequestQueue(this);
JsonObjectRequest jsonObjReq = new JsonObjectRequest(Method.POST,
Constants.BASE_URL + Constants.LOGIN, null, response,
response_error) {
/**
* Passing some request headers
* */
@Override
public Map<String, String> getHeaders() throws AuthFailureError {
HashMap<String, String> headers = new HashMap<String, String>();
headers.put("Content-Type", "application/json");
return headers;
}
@Override
protected Map<String, String> getPostParams()
throws AuthFailureError {
// TODO Auto-generated method stub
Map<String, String> params = new HashMap<String, String>();
params.put("key", "value");
return params;
}
};
// implementation of listeners
Response.Listener<JSONObject> response = new Response.Listener<JSONObject>() {
@Override
public void onResponse(JSONObject response) {
Log.d(TAG, response.toString());
Log.e("responce", response.toString());
// msgResponse.setText(response.toString());
hideProgressDialog();
}
};
Response.ErrorListener response_error = new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
Log.e("error responce", error.getMessage());
VolleyLog.d(TAG, "Error: " + error.getMessage());
hideProgressDialog();
}
};
//get params never get called
//i also tried alternative to send params but does not works.
Map<String, String> params = new HashMap<String, String>();
params.put("key", "value");
JsonObjectRequest jsonObjReq = new JsonObjectRequest(Method.POST,
Constants.BASE_URL + Constants.LOGIN, new JSONObject(params), response,
response_error) {
/**
* Passing some request headers
* */
@Override
public Map<String, String> getHeaders() throws AuthFailureError {
HashMap<String, String> headers = new HashMap<String, String>();
headers.put("Content-Type", "application/json");
return headers;
}
};
any type of help will be appretiated, Thanks in advance.
