无法通过公司代理进行HTTPS SOAP调用-getaddrinfo ENOTFOUND

Question

我正在尝试通过HTTPS进行SOAP调用。通常，我是通过Azure来执行此操作的，但工作正常，但是我正在开发一个新模块，需要通过我们的公司代理在本地调用它。如果我只是正常拨打电话，则会收到SELF_SIGNED_CERTIFICATE_IN_CHAIN错误消息。在某些情况下，我可以使用https-proxy-agent模块来解决此问题，但是当我按如下所示进行设置时，我收到了错误消息getaddrinfo ENOTFOUND undefined undefined:80。我确定代理URL有效。在调试该调用时，我可以看到代理信息正在传递给该调用（通过easy-soap-request启动SOAP调用，这又通过axios进行了HTTP调用）。以下是一些相关的代码片段：

const soapRequest = require('easy-soap-request');
let httpsProxyAgent = require('https-proxy-agent');
var agent = new httpsProxyAgent({hostname:'proxy.address.com', port:8080, rejectUnauthorized:false});

// Next lines are within the class of my helper function

await (async () => {
            var response = {};
            try {
                console.log('Converting catalog number...');
                console.log(url);
                response = await soapRequest(url, headers, requestXML, 10000, {httpsAgent:agent});

            } catch (err) {
                console.log(`Error converting catalog number: ${err}`);
                processObj.message = 'SERVICE_DOWN';
                processObj.error = err.message;
                return;
            }

// Then do some more stuff with the response, but I don't get this far

easy-soap-request模块本身似乎并没有做很多事情。让我想知道为什么我不只是发表request-promise-native（我用于所有其他API调用）的帖子，但我想这是重点。这是easy-soap-request模块供参考。我唯一注意到的是它实际上是在使用axios-https-proxy-fix而不是axios。

const axios = require('axios-https-proxy-fix');

module.exports = function soapRequest(url, headers, xml, timeout = 10000, proxy = false) {
  return new Promise((resolve, reject) => {
    axios({
      method: 'post',
      url,
      headers,
      data: xml,
      timeout,
      proxy,
    }).then((response) => {
      resolve({
        response: {
          headers: response.headers,
          body: response.data,
          statusCode: response.status,
        },
      });
    }).catch((error) => {
      if (error.response) {
        console.error(`SOAP FAIL: ${error}`);
        reject(error.response.data);
      } else {
        console.error(`SOAP FAIL: ${error}`);
        reject(error);
      }
    });
  });
};

似乎我对easy-soap-request并未真正增加太多价值的评论被证明是正确的。我很容易使用request-promise-native作为替代产品。并且由于后者尊重我的.env代理变量，因此我也不需要使用httpsAgent。我仍然必须在选项中添加rejectUnauthorized:false。这是更新后的代码，其中原始行已被注释掉：

//const soapRequest = require('easy-soap-request');
//let httpsProxyAgent = require('https-proxy-agent');
//var agent = new httpsProxyAgent({hostname:'proxy.address.com', port:8080, rejectUnauthorized:false});
const request = require('request-promise-native');

// Next lines are within the class of my helper function

await (async () => {
            var response = {};
            try {
                console.log('Converting catalog number...');
                console.log(url);
                //response = await soapRequest(url, headers, requestXML, 10000, {httpsAgent:agent});
                response = await request({
                    url: url,
                    method: 'POST',
                    headers: headers,
                    body: requestXML,
                    rejectUnauthorized: false
                })

            } catch (err) {
                console.log(`Error converting catalog number: ${err}`);
                processObj.message = 'SERVICE_DOWN';
                processObj.error = err.message;
                return;
            }

像魅力一样运作！实际上，我将返回并更新其他集成模块以使用此方法，而不是在整个应用程序中使用easy-soap-request。
