我需要针对SOCKS代理设置代理身份验证.我发现这篇文章提供的说明似乎与常见的HTTP代理一起使用.

        httpclient.getHostConfiguration().setProxy("proxyserver.example.com", 8080);

        HttpState state = new HttpState();
        state.setProxyCredentials(new AuthScope("proxyserver.example.com", 8080), 
           new UsernamePasswordCredentials("username", "password"));
        httpclient.setState(state);

这也适用于SOCKS代理,还是我必须做一些不同的事情？

我正在使用 Apache HTTPClient API 发送 HTTPRequest，到目前为止它可以处理标准请求。现在我想发送 GWT-RPC 请求并显示响应，但我总是从 GWT-RPC 服务器收到以下错误：

 //EX[2,1,"com.google.gwt.user.client.rpc.IncompatibleRemoteServiceException/3936916533","This application is out of date, please click the refresh button on your browser. ( Malformed or old RPC message received - expecting version 5 )"],0,5]

实际上，我必须随请求发送以下数据：

5|0|5|http://172.16.103.244:38081/kunagi/scrum.ScrumGwtApplication/|6E611C647A0C98D5A31A2506E16D81D6|scrum.client.ScrumService|startConversation|I|1|2|3|4|1|5|-1|

但我不知道怎么做。

当我从 FireBug 检索请求代码时，我在帖子区域中找到了上述数据作为来源。

我设置了一个 HTTPS 代理，以便 HTTP 客户端可以安全地向代理发送纯 HTTP 请求。例如，客户端可以向代理发送加密的 HTTP GET 请求，代理将删除加密并将纯 HTTP GET 请求发送到终端站点。

我了解到这不是一个常见的设置，只有谷歌浏览器具有支持这种情况的内置功能。（此处的信息 - http://wiki.squid-cache.org/Features/HTTPS#Encrypted_browser-Squid_connection）。我已经让谷歌浏览器与我的 HTTPS 代理一起工作，因此代理端没有问题。

我希望编写一个 HTTP 客户端来加密对我的 HTTPS 代理的所有请求。我尝试通过这种方式将 HTTPS 代理设置为 DefaultHttpClient -

DefaultHttpClient dhc = new DefaultHttpClient();
HttpHost proxy = new HttpHost("192.168.2.3", 8181, "https"); //NOTE : https
dhc.getParams().setParameter(ConnRoutePNames.DEFAULT_PROXY, proxy);

然后尝试执行任何请求都会给我一个 SSLPeerUnverifiedException。我不明白为什么。

在探索 DefaultHttpClient API 的过程中，我遇到了 HttpRoutePlanner 和 HttpRoute，我们可以使用它们来指定是否应该加密与代理的连接。但是，我无法完成这项工作。

这是一个图表，通过将它与 HTTP 代理设置区分开来解释我的设置 -

HTTP代理：

HTTP Client <------- Plain Text GET, POST Requests -------> HTTP Proxy <------- Plain Text GET, POST Requests -------> HTTP End-Site

我目前正在做一个小项目。该项目的目的是登录网站并获取/处理网站上的信息。此外，我想打开一些链接并搜索它们。

服务器端看起来像这样：

您需要登录到一个 php 站点。成功登录后，您将获得一个会话并将被重定向到 foo.username.bar.php（已更改）。

使用此代码：

BufferedReader in = null;
    String data = null;
    try {
        List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
        nameValuePairs.add(new BasicNameValuePair("username",  user));
        nameValuePairs.add(new BasicNameValuePair("passwort", pass));

        HttpClient client = new DefaultHttpClient();
        HttpPost request = new HttpPost(website);
        request.setEntity(new UrlEncodedFormEntity(nameValuePairs));
        HttpResponse response = client.execute(request);
        in = new BufferedReader(new InputStreamReader(response.getEntity()
                .getContent()));
        StringBuffer sb = new StringBuffer("");
        String l = "";
        String nl = System.getProperty("line.separator");
        while ((l = in.readLine()) != null) {
            sb.append(l + nl);
        }
        in.close();
        data = sb.toString();
        return data; …

我正在寻找此链接,我正在尝试向服务器发送请求

public class Test {
    public static void main(String[] args) throws ClientProtocolException, IOException {

        DefaultHttpClient httpClient;
        URL url = new URL("https://9.5.127.34:443");
        httpClient = getSSLHttpClient(url);
        CredentialsProvider credsProvider = new BasicCredentialsProvider();
        credsProvider.setCredentials(
                new AuthScope("https://9.5.127.34", AuthScope.ANY_PORT),
                new UsernamePasswordCredentials("root", "passw0rd"));


         httpClient.setCredentialsProvider(credsProvider);


        HttpGet httpget = new HttpGet("https://9.5.127.34/powervc/openstack/volume/v1/115e4ad38aef463e8f99991baad1f809//volumes/3627400b-cd98-46c7-a7e2-ebce587a0b05/restricted_metadata");
        HttpResponse response = httpClient.execute(httpget);
        BufferedReader rd = new BufferedReader(new InputStreamReader(response.getEntity().getContent()));
        String line = "";
        while ((line = rd.readLine()) != null) {

            System.out.println(line);

            }   
        }

但它给了我错误

Authentication required

请告诉我我做错了什么.Thanx提前

我使用Spring作为技术。用于调用Web 服务的 Apache HttpClient。基本目的是上传分段文件（文件不是任何图像文件或视频文件）。但在这里我的要求略有不同。请检查下图。

在这里你可以看到第一个块。它是一个简单的 GUI，只有 2 个输入标签和正确的表单标签。

在第二个块中，有 RESTFul Webservice，它以 Multipart File 作为参数并对其进行处理。（到此为止已经完成了）。
现在我被困在这里。我想将此多部分文件发送到其他仅使用多部分文件的 RESTFul Web 服务。

RESTFUL Webservice 的代码片段：（评论了一些问题，需要您的建议）

@RequestMapping(value="/project/add")
public @ResponseBody String addURLListToQueue(
        @RequestParam(value = "file") MultipartFile file,
        @RequestParam(value = "id1", defaultValue = "notoken") String projectName,
        @RequestParam(value = "id2", defaultValue = "notoken") String id2,
        @RequestParam(value = "id3", defaultValue = "notoken") String id3){

HttpClient httpclient = new DefaultHttpClient();
httpclient.getParams().setParameter(CoreProtocolPNames.PROTOCOL_VERSION, HttpVersion.HTTP_1_1);

HttpPost httppost = new HttpPost("http://localhost:8080/fs/project/add");

// 1) Do I need to convert …

由于一些漏洞，我们需要从 commons-httpclient-3.1.jar 移动到 httpclient-4.5.2.jar

现在有一个之前在 3.1 上工作的代码库，但这些方法在 4.5.2 中已弃用。您对如何克服这些错误有任何想法或遇到过

我得到的错误是 1) 无法解析导入 org.apache.commons.httpclient.HostConfiguration 2) 方法 getState() 对于 HttpClient 类型未定义

这是源代码。如果您有任何信息，请告诉我。

我已经了解了HttpClient如何LocalTestServer用于自动化测试,但我似乎无法找到它被移动的位置.我尝试httpclient使用tests分类器定义依赖:

'org.apache.httpcomponents:httpclient:4.5.2:tests'

但似乎没有LocalTestServer定义一个类.这已经停止了吗？

我有一个 REST 服务，每天处理大约 2000 万个请求。我收到以下异常。此问题是间歇性的，我无法将此问题与请求量联系起来。我在周末也遇到了这个例外，当时成交量非常低。我确实通过检查确保没有石碑连接setStaleConnectionCheckEnabled。我在用着httpclient 4.3.4

更新：进一步分析后的一些更多细节 -

从日志中，我可以看到服务在 300 毫秒内响应了大部分请求，但是客户端需要时间连接到服务本身，并且在收到响应时，它已经超过了 6 秒的阈值并进入了读取时间出异常。

升级到Spring Boot 2.0.1后,我的应用程序遇到了无法解释的问题.

涉及两个应用程序.对App 1的请求向App 2进行后端调用以获取某些数据.对App 2的调用通过AWS弹性负载均衡器(ELB)进行.用于进行调用的客户端是由我的实用程序包装的Apache Commons HttpClient .

在App 1升级到Boot 2.0.1之后,我看到从App 1到App 2的一小部分呼叫都挂了很长时间(15分钟).当我使用JConsole获取挂起线程的线程转储时,我看到了这个堆栈跟踪:
