我试图在Android代码中做一个简单的GET请求,我只是从Volley的官方网站复制了代码,但我得到一个错误说:"无法解析符号"方法"".
我的代码是这样的:
public void onReceive(final Context context, Intent intent) {
// Instantiate the RequestQueue.
RequestQueue queue = Volley.newRequestQueue(context);
String url = ***** ; // my URL
// Request a string response from the provided URL.
StringRequest stringRequest = new StringRequest(DownloadManager.Request.Method.GET, url,
new Response.Listener<String>() { //the error is in THIS line
@Override
public void onResponse(String response) {
// Display the first 500 characters of the response string.
Toast.makeText(context, "Response is: " + response.substring(0,500), Toast.LENGTH_LONG).show();
}
}, new Response.ErrorListener() {
@Override
public …我想在Android中发送一个简单的POST请求,其中一个正文等于:
[
{
"value": 1
}
]
我尝试在Android中使用Volley库,这是我的代码:
// the jsonArray that I want to POST
String json = "[{\"value\": 1}]";
JSONArray jsonBody = null;
try {
jsonBody = new JSONArray(json);
} catch (JSONException e) {
e.printStackTrace();
}
final JSONArray finalJsonBody = jsonBody;
// starting the request
final RequestQueue queue = Volley.newRequestQueue(getApplicationContext());
JsonObjectRequest request =
new JsonObjectRequest(com.android.volley.Request.Method.POST,"https://...",null,
new Response.Listener<JSONObject>() {
@Override
public void onResponse(JSONObject response) {
Log.d("mytag", "Response is: " + response);}},
new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) …
