okhttp客户端在TMG代理服务器下抛出异常 [英] okhttp client throwing exception under TMG proxy server
问题描述
我正在为我的java应用程序使用github的方形OKHTTP客户端库，如下所示：
I'm using github's square OKHTTP client library for my java application as follows :
import java.io.IOException;
import java.net.InetSocketAddress;
import java.net.Proxy;
import java.security.cert.CertificateException;
import java.security.cert.X509Certificate;
import javax.net.ssl.HostnameVerifier;
import javax.net.ssl.SSLContext;
import javax.net.ssl.SSLSession;
import javax.net.ssl.TrustManager;
import javax.net.ssl.X509TrustManager;
import com.squareup.okhttp.Authenticator;
import com.squareup.okhttp.Credentials;
import com.squareup.okhttp.OkHttpClient;
import com.squareup.okhttp.Request;
import com.squareup.okhttp.Response;
public class TestOkHttp {
static public void main(String argcp[]){
try {
OkHttpClient okHttpClient = new OkHttpClient();
TrustManager[] trustAllCerts = new TrustManager[] {
new X509TrustManager() {
@Override
public X509Certificate[] getAcceptedIssuers() {
// TODO Auto-generated method stub
return null;
}
@Override
public void checkServerTrusted(X509Certificate[] arg0, String arg1)
throws CertificateException {
// TODO Auto-generated method stub
}
@Override
public void checkClientTrusted(X509Certificate[] arg0, String arg1)
throws CertificateException {
// TODO Auto-generated method stub
}
}};
SSLContext sc = SSLContext.getInstance("TLS");
sc.init(null, trustAllCerts, new java.security.SecureRandom());
okHttpClient.setSslSocketFactory(sc.getSocketFactory());
Proxy p=new Proxy(Proxy.Type.HTTP,new InetSocketAddress("10.1.1.0", 8080));
okHttpClient.setProxy(p);
HostnameVerifier hostNameVerifier = new HostnameVerifier() {
@Override
public boolean verify(String sourceHost, SSLSession arg1) {
// TODO Auto-generated method stub
return sourceHost.equals("serverwithtls.com");
}
};
okHttpClient.setHostnameVerifier(hostNameVerifier);
okHttpClient.setAuthenticator(new Authenticator() {
@Override
public Request authenticateProxy(Proxy proxy, Response response)
throws IOException {
String credential = Credentials.basic("username","password");
return response.request().newBuilder()
.header("Authorization", credential)
.build();
}
@Override
public Request authenticate(Proxy arg0, Response arg1)
throws IOException {
// TODO Auto-generated method stub
return null;
}
});
Request request = new Request.Builder()
.url("https://serverwithtls.com")
.build();
Response response = okHttpClient.newCall(request).execute();
System.out.println(response.body().string());
} catch (Exception e) {
e.printStackTrace();
}
}
}
我的网络连接是Microsoft TMG代理服务器后面需要代理用户身份验证，执行上述代码时出现以下异常：
My network connection is behind a Microsoft TMG proxy server which requires proxy user authentication, I get the following exception upon execution of the above code :

我尝试在不同的代理服务器下工作，工作得很好。
I tried working under different proxy servers, worked perfectly.
任何帮助？
推荐答案
看起来好像是OkHttp中的一个错误，我们在那里没有扔掉407上的完整响应体。打开一个我们的GitHub问题跟踪器问题&我会看一看。如果公共互联网可以访问感兴趣的代理，请私下发送给我， jesse@swank.ca 我会确认这一点。
Looks like a bug in OkHttp, where were we're not throwing away the full response body on a 407. Open an issue on our GitHub issue tracker & I'll take a look. If the proxy of interest is reachable by the public Internet, send it to me privately, jesse@swank.ca and I'll confirm this.
