所以,我有这个Volley PUT请求：
private boolean syncCall(JSONObject jsonObject,final VolleyCallback
callback) {
final ProgressDialog progDailog = new ProgressDialog(context);
final Boolean[] success = {false};
progDailog.setMessage("...");
progDailog.setIndeterminate(false);
progDailog.setProgressStyle(ProgressDialog.STYLE_SPINNER);
progDailog.setCancelable(false);
progDailog.show();
final SharedPreferences prefs = PreferenceManager
.getDefaultSharedPreferences(context);
RequestQueue queue = Volley.newRequestQueue(context,new HurlStack());
final String token = prefs.getString("token",null);
String URL = Constants.getUrlSync();
String param1 = String.valueOf(prefs.getInt("pmp",1));
String param2 = String.valueOf(prefs.getInt("ei",1));
URL = URL.replace("[x]",param1);
URL = URL.replace("[y]",param2);
//pegar id pmp e IE corretas
JsonObjectRequest jsObjRequest = new JsonObjectRequest(Request
.Method.PUT,URL,jsonObject,new Response.Listener<JSONObject>() {
@Override
public void onResponse(JSONObject response) {
callback.onSuccess(response + "");
success[0] = true;
progDailog.dismiss();
}
},new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
callback.onFailure(error);
tokenFailure(error);
success[0] = false;
progDailog.dismiss();
}
}) {
@Override
public Map<String,String> getHeaders() throws
AuthFailureError {
HashMap<String,String> headers = new HashMap<>();
headers.put("Token",token);
return headers;
}
};
int socketTimeout = 30000;
RetryPolicy policy = new DefaultRetryPolicy(socketTimeout,DefaultRetryPolicy.DEFAULT_MAX_RETRIES,DefaultRetryPolicy.DEFAULT_BACKOFF_MULT);
jsObjRequest.setRetryPolicy(policy);
queue.add(jsObjRequest);
return success[0];
}
我的问题是我发送了一个非常大的JSON,所以5秒的默认超时是不够的.因此,我尝试将超时增加到30秒,并且使用DefaultRetryPolicy来增加重试次数.
问题是,它在5s内保持计时,甚至不会重试一次！
我是否必须有一个监听器或回调重试？我在使用DefaultRetryPolicy做错了什么？请帮忙,这个问题让我疯狂……
解决方法
您需要使用DefaultRetryPolicy吗？
因为你可以定义自己的.
而不是这个：
RetryPolicy policy = new DefaultRetryPolicy(socketTimeout,DefaultRetryPolicy.DEFAULT_BACKOFF_MULT);
试试这个：
jsObjRequest.setRetryPolicy(new RetryPolicy() {
@Override
public int getCurrentTimeout() {
// Here goes the new timeout
return mySeconds;
}
@Override
public int getCurrentRetryCount() {
// The max number of attempts
return myAttempts;
}
@Override
public void retry(VolleyError error) throws VolleyError {
// Here you could check if the retry count has gotten
// To the max number,and if so,send a VolleyError msg
// or something
}
});
