关于httpclient peer not authenticated的问题

出现此问题主要原因是因为在请求过程中证书的问题；有些客户端并未安装服务器要求的证书，所以会产生此问题，以下是部分报错代码：

javax.net.ssl.SSLPeerUnverifiedException: peer not authenticated

解决办法就是：

//以下是部分需要引用的jar 包

import org.apache.http.HttpResponse;
import org.apache.http.client.ClientProtocolException;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.mime.MultipartEntity;
import org.apache.http.impl.client.DefaultHttpClient;
import java.security.cert.X509Certificate;

import javax.net.ssl.SSLContext;
import javax.net.ssl.TrustManager;
import javax.net.ssl.X509TrustManager;
import org.apache.http.conn.ssl.SSLSocketFactory;
import org.apache.http.conn.ClientConnectionManager;
import org.apache.http.conn.scheme.Scheme;
import org.apache.http.conn.scheme.SchemeRegistry;

//以下代码是定义HttpClient
HttpClient client = new DefaultHttpClient();

//将client 转换

client = wrapClient(client);

 

 

//以下是wrapClient方法

/**
* 获取可信任https链接，以避免不受信任证书出现peer not authenticated异常
*
* @param base
* @return
*/
public static HttpClient wrapClient(HttpClient base) {
try {
SSLContext ctx = SSLContext.getInstance(“TLS”);
X509TrustManager tm = new X509TrustManager() {
public void checkClientTrusted(X509Certificate[] xcs,
String string) {
}

public void checkServerTrusted(X509Certificate[] xcs,
String string) {
}

public X509Certificate[] getAcceptedIssuers() {
return null;
}
};
ctx.init(null, new TrustManager[] { tm }, null);
SSLSocketFactory ssf = new SSLSocketFactory(ctx);
ssf.setHostnameVerifier(SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);
ClientConnectionManager ccm = base.getConnectionManager();
SchemeRegistry sr = ccm.getSchemeRegistry();
sr.register(new Scheme(“https”, ssf, 443));

return new DefaultHttpClient(ccm, base.getParams());
} catch (Exception ex) {
ex.printStackTrace();
return null;
}
}

 

 

 

//以下是client 的使用，可以和正常的client 使用一样了，，get方法使用

// 定义HttpClient
HttpClient client = new DefaultHttpClient();
client = wrapClient(client);
// 实例化HTTP方法
HttpGet request = new HttpGet();
request.setURI(new URI(url));
HttpResponse response = client.execute(request);
InputStream is = response.getEntity().getContent();

 

//以下是client 的使用，可以和正常的client 使用一样了，，post方法使用

HttpPost postrequest = new HttpPost(url);
try {
if (parameters != null) {
postrequest.setEntity(parameters);
}
HttpResponse postresponse = client.execute(postrequest);
InputStream is = postresponse.getEntity().getContent();
return is;
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
throw e;
} catch (ClientProtocolException e) {
e.printStackTrace();
throw e;
} catch (IOException e) {
e.printStackTrace();
throw e;
} catch (Exception e) {
e.printStackTrace();
throw e;
}
