找了半天也没找到靠谱的地方，最后没办法去阿帕奇的官网找了找，找到个demo，已测试成功，希望能帮助后面的人。[/quote]忘了把地址挂上了 https://hc.apache.org/httpcomponents-client-ga/httpclient/examples/org/apache/http/examples/client/ClientProxyAuthentication.java

楼主能讲解一下么，我试了很多次，还是行不通。
例如：我的代理是proxy.future.com,端口8080
用户：xiaoli，密码：000000
调用的请求：
HttpGet httpGet = new HttpGet("http://www.ip138.com:8080/search.asp?mobile=13000467124&action=mobile");
理论上设置这四个数就行了，为什么有多个认证范围，我怎么调用都报错：java.net.UnknownHostException: localhost.localdomain
如果楼主方便的话，请帮我写一下代码，先谢谢了。

对我帮助挺大的 谢谢！！
/**
* 设置代理
* @return
*/
public static CloseableHttpClient getHttpClient(String hostOrIP,int port,String userName,String password){
//设置代理地址、代理端口号、协议类型
HttpHost proxy = new HttpHost(hostOrIP,port,"http");
DefaultProxyRoutePlanner routePlanner = new DefaultProxyRoutePlanner(proxy);
//创建认证，并设置认证范围
CredentialsProvider credsProvider = new BasicCredentialsProvider();
credsProvider.setCredentials(new AuthScope(hostOrIP,port),new UsernamePasswordCredentials(userName, password));
HttpClientBuilder builder = HttpClients.custom();
builder.setRoutePlanner(routePlanner);
builder.setDefaultCredentialsProvider(credsProvider);
CloseableHttpClient httpclient = builder.build();
// CloseableHttpClient httpclient = builder.create().build();
return httpclient;
}

上下 我最后使用的代码，希望可以帮到有需要的人
//创建认证，并设置认证范围
CredentialsProvider credsProvider = new BasicCredentialsProvider();
credsProvider.setCredentials(new AuthScope(HsbcSmsUtilConfiguration.getPROXY_ADDRESS(), HsbcSmsUtilConfiguration.getPROXY_PORT()),//可以访问的范围
new UsernamePasswordCredentials(HsbcSmsUtilConfiguration.getPROXY_USERNAME(), HsbcSmsUtilConfiguration.getPROXY_PASSWORD()));//用户名和密码
CloseableHttpClient client = HttpClients.custom().setDefaultCredentialsProvider(credsProvider).build();
String responseText = "";
CloseableHttpResponse response = null;
// 访问的目标站点，端口和协议
HttpHost targetHost = new HttpHost(HsbcSmsUtilConfiguration.getURI(), 443, "https");
System.out.println(targetHost);
// 代理的设置
HttpHost proxy = new HttpHost(HsbcSmsUtilConfiguration.getPROXY_ADDRESS(), HsbcSmsUtilConfiguration.getPROXY_PORT());
RequestConfig config = RequestConfig.custom().setProxy(proxy).build();

你去网上找 4.3啊。
CloseableHttpClient httpclient = <...>
HttpHost targetHost = new HttpHost("localhost", 80, "http");
CredentialsProvider credsProvider = new BasicCredentialsProvider();
credsProvider.setCredentials(
new AuthScope(targetHost.getHostName(), targetHost.getPort()),
new UsernamePasswordCredentials("username", "password"));
// Create AuthCache instance
AuthCache authCache = new BasicAuthCache();
// Generate BASIC scheme object and add it to the local auth cache
BasicScheme basicAuth = new BasicScheme();
authCache.put(targetHost, basicAuth);
// Add AuthCache to the execution context
HttpClientContext context = HttpClientContext.create();
context.setCredentialsProvider(credsProvider);
context.setAuthCache(authCache);
HttpGet httpget = new HttpGet("/");
for (int i = 0; i < 3; i++) {
CloseableHttpResponse response = httpclient.execute(
targetHost, httpget, context);
try {
HttpEntity entity = response.getEntity();
} finally {
response.close();
}

你帮我看下这个，public static String post(String url, Map<String, String> paramsMap) {
{
/* // yupian网地址
private static String URI = "yunpian.com";
//代理地址
private static String proxyAddress="10.0.0.122";
//代理地址的端口号
private static Integer proxyPort=1993;*/
// 创建HttpClientBuilder
HttpClientBuilder httpClientBuilder = HttpClientBuilder.create();
CloseableHttpClient client =httpClientBuilder.build();
String responseText = "";
CloseableHttpResponse response = null;
// 访问的目标站点，端口和协议
HttpHost targetHost = new HttpHost(URI, 443, "https");
System.out.println(targetHost);
// 代理的设置
HttpHost proxy = new HttpHost(proxyAddress, proxyPort);
RequestConfig config = RequestConfig.custom().setProxy(proxy).build();
try {
HttpPost method = new HttpPost(url);
method.setConfig(config);
if (paramsMap != null) {
List<NameValuePair> paramList = new ArrayList<NameValuePair>();
for (Map.Entry<String, String> param : paramsMap.entrySet()) {
NameValuePair pair = new BasicNameValuePair(param.getKey(), param.getValue());
paramList.add(pair);
}
method.setEntity(new UrlEncodedFormEntity(paramList, ENCODING));
}
response = client.execute(targetHost, method);
HttpEntity entity = response.getEntity();
if (entity != null) {
responseText = EntityUtils.toString(entity);
}
} catch (Exception e) {
e.printStackTrace();
} finally {
try {
response.close();
} catch (Exception e) {
e.printStackTrace();
}
}
// System.out.println(responseText);
return responseText;
}
}
上面的这段代码用了代理，但是现在想让代理有用户名和密码，不知道在那里设置，找了好久了，不知道怎么去做

System.getProperties().setProperty("proxySet", "true");
System.getProperties().setProperty("http.proxyHost", "xxxxxx");
System.getProperties().setProperty("http.proxyPort", "8080");
这种不行吗
