asynchttpclient

问题 I'm evaluating AsyncHttpClient for big loads (~1M HTTP requests). For each request I would like to invoke a callback using the AsyncCompletionHandler which will just insert the result into a blocking queue My question is: if I'm sending asynchronous requests in a tight loop, how many threads will the AsyncHttpClient use? (I know you can set the max but apparently you take a risk of losing requests, I've seen it here) I'm currently using the Netty implementation with these versions: async-http

问题 On Async Http Client documentation I see how to get a Future<Response> as the result of an asynchronous HTTP Get request simply doing, for example: AsyncHttpClient asyncHttpClient = new DefaultAsyncHttpClient(); Future<Response> f = asyncHttpClient .prepareGet("http://api.football-data.org/v1/soccerseasons/398") .execute(); Response r = f.get(); However, for convenience I would like to get a CompletableFuture<T> instead, for which I could apply a continuation that converts the result in

问题 I am using AsyncHttpClient for uploading image and data to server.But data and image are not uploaded. I dont know what mistake i have done. Can anyone help me? My Code: package com.example.asynchttpclientex; import java.io.File; import java.io.FileNotFoundException; import org.apache.http.Header; import android.os.Bundle; import android.support.v7.app.ActionBarActivity; import android.util.Log; import android.view.View; import android.view.View.OnClickListener; import android.widget.Button;

问题 I am using ning AsyncHttpClient from a command line program. I need to wait for all requests to end so I can safely call close() on the client. The challenge is that I make many requests from many different parts of the program. Stripped own code below that shows one scenario where I do a nested HTTP request from the onCompleted of another request: final AsyncHttpClient asyncHttpClient = new AsyncHttpClient(); Future<Response> f1 = asyncHttpClient.prepareGet(url).execute( new

问题 I'm new to C# and I'm very likely misunderstanding the the proper usage of await,async and Tasks :) I want to develop a class ( OWConnector ) that serves as API client for my app, for this purpose I develop a generic PostRequest method to perform POST request. Unfortunately the app looks like is going into a deadlock when I user the auth method (that uses the generic method PostRequest ). Can you help me to understand where is the problem ? I marked in the code where the debugger await

问题 Here is an updated version of the code posted under httpclient.GetStringAsync blocking The question is when cancel is done, though the tasks are cancelled, I am expecting Await Task.WhenAll(tasks) to return and print whats in finally , but its not. I can see task cancellations when pressing cancel and I also see the connections reduce to 0, but the finally guessing WhenAll still thinks some tasks are being executed. Here is the code: Private concurrencySemaphore As New SemaphoreSlim(10)

问题 I use AsyncHttpClient with Netty provider to get response body. It works ok with most responses, the problem is with multipart ContentType. For example, this response: HTTP/1.1 200 OK Server: Apache-Coyote/1.1 Content-Type: multipart/related; type="application/xop+xml"; boundary="uuid:2dfd79bd-bdd5-4e15-bf4a-d08b63918c37"; start="<root.message@cxf.apache.org>"; start-info="text/xml";charset=UTF-8 Transfer-Encoding: chunked Date: Fri, 20 Mar 2015 13:09:50 GMT --uuid:2dfd79bd-bdd5-4e15-bf4a

问题 I must be doing something wrong since this code is blocking and runs synchronously, inspite of calling the async method of GetStringAsync . Any help would really help me understand the reasons: Private Async Sub btnTest_Click(sender As Object, e As EventArgs) Handles btnTest.Click Dim urls As List(Of String) = SetUpURLList() Dim baseAddress = New Uri("http://www.amazon.com") ServicePointManager.DefaultConnectionLimit = 10 Dim requestNumber As Integer = 0 For Each url In urls requestNumber +=

问题 I am trying to combine AsyncHttpClient and Scalaz Task together. Normally, if I am using AsyncHttpClient, I can invoke client.close to stop the client. val asyncHttpClient = new AsyncHttpClient() println(asyncHttpClient.prepareGet("http://www.google.com")) asyncHttpClient.close() So current will be stopped. However, if I wrap the api call into the Task. I dont know how to stop it. def get(s: String) = Task.async[Int](k => { asyncHttpClient.prepareGet(s).execute(toHandler) Thread.sleep(5000)

问题 I am facing some difficulty in my code. I am initializing my drawer from json response, but my 'OnSuccess' method gives response when my activity gets over. also if I initialized arraylist in OnSuccess It still gives empty in OnCreate method because OnSuccess method gives response when activity is finished. Please can anybody help me. Here is a sample code. @Override public void onActivityCreated(Bundle savedInstanceState) { super.onActivityCreated(savedInstanceState); // Indicate that this
