Android volley 库不接受来自 getParam() 的 url 中的参数
Android volley library is not accepting parameters in url from getParam()
Android volley 库不接受来自 getParam() 的参数 method.If 它在查询字符串中给出然后它 works.I 尝试了 GET 和 POST 它没有'行得通。但我想给参数 POST Method.please 检查我在下面发布的代码。
RequestQueue queue = Volley.newRequestQueue(getApplicationContext());
String url = AppConstants.WEBSERVICE_URL
+ AppConstants.WEBSERVICE_URL_POST_COMMENT;
StringRequest getRequest = new StringRequest(Request.Method.GET, url,
new Response.Listener<String>() {
@Override
public void onResponse(String response) {
// response
Log.d("Response_postComment", response);
Intent intent = new Intent(getApplicationContext(),
ReviewActivity.class);
intent.putExtra("serviceId", servicePosition);
startActivity(intent);
}
}, new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
// error
Log.d("Error.Response", error.toString());
}
}) {
@Override
public Map<String, String> getHeaders() throws AuthFailureError {
Map<String, String> pars = new HashMap<String, String>();
pars.put("Content-Type", "application/x-www-form-urlencoded");
return pars;
}
@Override
protected Map<String, String> getParams() throws AuthFailureError{
Map<String, String> params = new HashMap<String, String>();
params.put("rating", ratingBar.getRating() + "");
params.put("com_content", comments.getText() + "");
params.put("user_id", AppConstants.APP_LOGIN_USER_ID);
params.put("comm_post_ID", AppConstants.arrListServiceDetail
.get(servicePosition).getId() + "");
return params;
}
};
getRequest.setRetryPolicy(new DefaultRetryPolicy(500000,
DefaultRetryPolicy.DEFAULT_MAX_RETRIES,
DefaultRetryPolicy.DEFAULT_BACKOFF_MULT));
queue.add(getRequest);
getParam() 方法不适用于 volley.its 上的 GET 请求,可与 POST 一起正常工作 methods.you 必须使用参数设置完整的 URL。
我遇到了与您现在面临的问题相同的问题,但提出了通过将核心 class 请求作为此请求的超级 class 来发出自定义请求的解决方案。在这里,我在构造函数中传递参数,然后将其返回给 getParams() 重写方法,如下所示:
public class RequestJson extends Request<JSONObject> {
private Listener<JSONObject> listener;
private Map<String, String> params;
public RequestJson(String url, Map<String, String> params,
Listener<JSONObject> reponseListener, ErrorListener errorListener) {
super(Method.GET, url, errorListener);
this.listener = reponseListener;
this.params = params;
}
public RequestJson(int method, String url, Map<String, String> params,
Listener<JSONObject> reponseListener, ErrorListener errorListener) {
super(method, url, errorListener);
this.listener = reponseListener;
this.params = params;
}
protected Map<String, String> getParams()
throws com.android.volley.AuthFailureError {
return params;
};
@Override
protected Response<JSONObject> parseNetworkResponse(NetworkResponse response) {
AppController.getInstance().checkSessionCookie(response.headers);
try {
String jsonString = new String(response.data,
HttpHeaderParser.parseCharset(response.headers));
return Response.success(new JSONObject(jsonString),
HttpHeaderParser.parseCacheHeaders(response));
} catch (UnsupportedEncodingException e) {
return Response.error(new ParseError(e));
} catch (JSONException je) {
return Response.error(new ParseError(je));
}
}
@Override
protected void deliverResponse(JSONObject response) {
// TODO Auto-generated method stub
listener.onResponse(response);
}
@Override
public Map<String, String> getHeaders() throws AuthFailureError {
Map<String, String> headers = super.getHeaders();
if (headers == null
|| headers.equals(Collections.emptyMap())) {
headers = new HashMap<String, String>();
}
AppController.getInstance().addSessionCookie(headers);
return headers;
}
}
希望这能解决您的问题。
