【问题描述】：

我有实现 Authenticator 接口的 ProxyAuthenticator 类。

public class ProxyAuthenticator implements Authenticator {

private String  proxyUser;
private String  proxyPassword;

public ProxyTessiAuthenticator(String proxyUser, String proxyPassword) {
    this.proxyUser = proxyUser;
    this.proxyPassword = proxyPassword;
}

@Override
public Request authenticateProxy(Proxy proxy, Response response) throws IOException {
    return authenticate(proxy, response);
}

@Override
public Request authenticate(Proxy proxy, Response response) throws IOException {
    String credential = Credentials.basic(proxyUser, proxyPassword);
    return response.request().newBuilder()
            .header("Proxy-Authorization", credential)
            .build();
}

}

我通过 com.squareup.okhttp 得到了这个异常：

java.net.ProtocolException: 后续请求太多：21

【解决方案1】：

如果您已经尝试过，则需要将其他身份验证请求短路。

        public Request authenticate(Route route, Response response) throws IOException {
            String credential = ...
            if (responseCount(response) >= 3) {
                return null;
            }
            return response.request().newBuilder().header("Authorization", credential).build();
        }
