HttpClient 模拟登陆，保持会话并进行后续操作 java

package cc.unmi.httpclient; import org.apache.commons.httpclient.Cookie; import org.apache.commons.httpclient.HttpClient; import org.apache.commons.httpclient.NameValuePair; import org.apache.commons.httpclient.cookie.CookiePolicy; import org.apache.commons.httpclient.methods.GetMethod; import org.apache.commons.httpclient.methods.PostMethod; import org.junit.Test; public class HttpClientLogin { public static void main(String[] args){ //登陆 Url String loginUrl = "http://localhost/unmi/login.html"; //需登陆后访问的 Url String dataUrl = "http://localhost/unmi/user_info.html?userid=123456"; HttpClient httpClient = new HttpClient(); //模拟登陆，按实际服务器端要求选用 Post 或 Get 请求方式 PostMethod postMethod = new PostMethod(loginUrl); //设置登陆时要求的信息，一般就用户名和密码，验证码自己处理了 NameValuePair[] data = https://www.it610.com/article/{ new NameValuePair("username", "Unmi"), new NameValuePair("password", "123456"), new NameValuePair("code", "anyany") }; postMethod.setRequestBody(data); try { //设置 HttpClient 接收 Cookie,用与浏览器一样的策略 httpClient.getParams().setCookiePolicy(CookiePolicy.BROWSER_COMPATIBILITY); httpClient.executeMethod(postMethod); //获得登陆后的 Cookie Cookie[] cookies=httpClient.getState().getCookies(); String tmpcookies= ""; for(Cookie c:cookies){ tmpcookies += c.toString()+"; "; } //进行登陆后的操作 GetMethod getMethod = new GetMethod(dataUrl); //每次访问需授权的网址时需带上前面的 cookie 作为通行证 getMethod.setRequestHeader("cookie",tmpcookies); //你还可以通过 PostMethod/GetMethod 设置更多的请求后数据 //例如，referer 从哪里来的，UA 像搜索引擎都会表名自己是谁，无良搜索引擎除外 postMethod.setRequestHeader("Referer", "http://unmi.cc"); postMethod.setRequestHeader("User-Agent","Unmi Spot"); httpClient.executeMethod(getMethod); //打印出返回数据，检验一下是否成功 String text = getMethod.getResponseBodyAsString(); System.out.println(text); } catch (Exception e) { e.printStackTrace(); } } }

Basic 验证的简单代码导引，还未亲试：

HttpClient client = new HttpClient(); // 1 client.getState().setCredentials( new AuthScope("unmi.cc", 80, AuthScope.ANY_REALM), new UsernamePasswordCredentials("username", "password") ); // 2 client.getParams().setAuthenticationPreemptive(true); // 3 GetMethod getMothod = new GetMethod("http://unmi.cc/twitter"); // 4 getMothod.setDoAuthentication( true ); // 5 int status = client.executeMethod( getMothod );
