【问题描述】：
我浏览了来自 salesforce SOAP API quick start 的示例代码，但我得到的只是第一次登录阶段的超时错误。我创建了一个开发人员登录并生成了 wsdl，然后是 .jar。程序编译。我目前正在尝试使用我在其他地方找到的以下示例：
import com.sforce.soap.enterprise.Connector;
import com.sforce.soap.enterprise.EnterpriseConnection;
import com.sforce.ws.ConnectionException;
import com.sforce.ws.ConnectorConfig;
public class Main {
static final String USERNAME = "username redacted";
static final String PASSWORD = "password redacted";
static final String AUTH = "https://login.salesforce.com/services/Soap/c/37.0/0DF58000000L2Vm";
static EnterpriseConnection connection;
public static void main(String[] args) {
ConnectorConfig config = new ConnectorConfig();
config.setUsername(USERNAME);
config.setPassword(PASSWORD);
config.setAuthEndpoint(AUTH);
try {
connection = Connector.newConnection(config);
// display some current settings
System.out.println("Auth EndPoint:"+config.getAuthEndpoint());
System.out.println("Service EndPoint:"+config.getServiceEndpoint());
System.out.println("Username: "+config.getUsername());
System.out.println("SessionId: "+config.getSessionId());
} catch (ConnectionException e1) {
e1.printStackTrace();
}
}
}
但是当我运行它时，它会挂起很长时间，然后给出一个 ConnectException: Connection timed out

我已经使用 wireshark 和我的系统管理员检查过它不是防火墙：DNS 查找正确解析了“login.salesforce.com”，并且肯定有包出去了。我还能做错什么？
【问题讨论】：
-
您确定这是有效的网址吗？尝试ping ip。 （使用nslook up）获取ip
-
@Optimuskck 通过正确解析我的意思是，如果我在网络浏览器中输入 DNS 返回的 ip（我可以在 wireshark 中看到），它会正确地将我带到“login.salesforce.com”
-
通常这是因为您的网络配置为必须使用代理服务器进行出站连接
