CertificateException with async-http-client for https

问题 I started having problems accessing a https://ws.plimus.com/ with async-http-client a few days ago. I get a "General SSLEngine problem" messages, and in the stack trace I can see it is caused by java.security.cert.CertificateException: Certificates does not conform to algorithm constraints This SO question describes basically the same thing. Commenting out the line in java.security makes the error go away, but I assume there is good reason for MD2 to be disabled. Using Raman's answer for

问题 I have a bolt that is making an API call (HTTP Get) for every tuple. to avoid the need to wait for the response, I was looking to use the apache HttpAsyncClient. after instantiating the client in the bolt's prepare method, the execute method constructs the URL from the tuple and calls sendAsyncGetRequest(url): private void sendAsyncGetRequest(String url){ httpclient.execute(new HttpGet(url), new FutureCallback<HttpResponse>() { @Override public void completed(HttpResponse response) { LOG.info

前端 andoid activity用到的函数 AsyncHttpClient 是一个框架提供的库 可以异步传输，使用时需下载android-async-http-1.4.4.jar包导入到项目中 [java] view plain copy public static void reg(final Context cont,Bitmap photodata,String regData) { try { ByteArrayOutputStream baos = new ByteArrayOutputStream(); //将bitmap一字节流输出 Bitmap.CompressFormat.PNG 压缩格式，100：压缩率，baos：字节流 photodata.compress(Bitmap.CompressFormat.PNG, 100, baos); baos.close(); byte[] buffer = baos.toByteArray(); System.out.println("图片的大小："+buffer.length); //将图片的字节流数据加密成base64字符输出 String photo = Base64.encodeToString(buffer, 0, buffer.length,Base64.DEFAULT); //photo

1. AsyncHttpClient, RequestParams ,AsyncHttpResponseHandler三个类使用方法 (1)AsyncHttpClient public class AsyncHttpClient extends java.lang.Object 该类通常用在android应用程序中创建异步GET, POST, PUT和DELETE HTTP请求，请求参数通过RequestParams实例创建，响应通过重写匿名内部类 ResponseHandlerInterface的方法处理。 例子： AsyncHttpClient client = new AsyncHttpClient(); client.get("http://www.baidu.com", new ResponseHandlerInterface() { @Override public void onSuccess(String response) { System.out.println(response); } }); (2)RequestParams public class RequestParams extends java.lang.Object 用于创建AsyncHttpClient实例中的请求参数(包括字符串或者文件)的集合 例子： RequestParams params

0. 文前闲话 作为一个Android开发的大龄初学者，面对扑面而来的各种姿势的Android的开源组件，让人倍感窒息，难以应对。无奈为了养家糊口，虽然已近不惑，人老珠黄，也只能废寝忘食，逐个体位细细揣摩研究，不断以身实践，争取早日小成。 话说那是一个阳光明媚的下午，我坐在街口转角处优雅的网络会所里，品着一杯上好的Coca-Cola，研读着oschina客户端源码，身旁不时传来：“一起上搞死他，他没蓝了...!”。 从火蚁（oschina客户端的开发者之一，向他们致敬）那里知道了async-http-client开源库，为了千千万万个没过英语四级的程序猿GG，就在这里翻译个作者写的"用户说明书"先... 1. async-http-client开源库简介 async-http-client库是一个基于回调函数的Http异步通信客户端Android组件，是在Apache的HttpClient库的基础上开发构建而成的。这里的异步，是指它所有的网络请求都是在app的UI线程之外的独立工作线程中执行。而开发者通过利用Android的消息处理机制，把我们所需要编写的回调函数放在这个回调函数的创建线程中执行（一般就是UI线程），所以使用起来非常方便，有了它，妈妈再也不用担心我被多线程同步搞死了。除了能应用在开发普通App上，还可以用来开发Service或后台线程， async-http
