IIS节点下的节点http请求对Azure CORS Web服务失败 - getaddrinfo ENOTFOUND

Question

当纯粹在节点下运行时，一切都运行正常，一旦我尝试在IIS节点下运行，每次使用getaddrinfo上的ENOTFOUND时，Node http请求都会失败。这是中型网站的一部分，其他所有内容都在Node和IIS Node下工作，只是对Azure CORS Web服务的请求失败。我也有类似的网络服务请求谷歌地图，在两种环境下都能很好地工作。 Google地图和Azure网络服务调用都使用相同的共享代码来处理请求。

// Simplified
//==================================
var http = require("http")

var options = {
  host: "xxx.azurewebsites.net",
  path: "/address?postcode=SL6+1PB",
  headers: {
    "SerialNo": "xxx",
    "RegKey": "xxx",
    "Company": "xxx"
  }
};

req = https.request(options, callback);
req.end();


// The Whole thing
//===========================
function getData(host, port, path, headers, data, secure) {
    return new promise(function(resolve, reject) {
            var options = {}, req;

        try {
            options.host = host;
            if(!!port) {options.port = port;}
            if(!!data) {options.method = "POST";}
            if(!!path) {options.path = path.replace(/\s+/g, "+");}
            if(!!headers) {options.headers = headers;}

            if(!!secure) {req = https.request(options, callback);}
            else {req = http.request(options, callback);}

            req.on("error", function(error) {
                rejectPromise(reject, error, "datahttp.getData");
            });

            if(!!data) {req.write((typeof(data) === "object" ? JSON.stringify(data) : data));}
            req.end();
        }
        catch(error) {
            // This error object drops the message property on stringify
            error = {method: "datahttp.getData", success: false, message: error.message};
            rejectPromise(reject, error, "datahttp.getData");
        }

        function callback(response) {
            var str = "";

            //another chunk of data has been received, so append it to `str`
            response.on("data", function(chunk) {
                str += String(chunk);
            });

            // the whole response has been received
            response.on("end", function () {
                if(response.statusCode == 200) {
                    try {
                        switch(response.headers["content-type"].split(";")[0]) {
                            case "application/xml":
                                xmlToJSN(str)
                                    .then(function(result) {
                                        resolve({method: "datahttp.getData", success: true, data: result});
                                    })
                                    .catch(function(error) {
                                        rejectPromise(reject, error, "datahttp.getData");
                                    });

                                break;

                            case "application/json":
                                resolve({method: "datahttp.getData", success: true, data: JSON.parse(str)});
                                break;

                            default:
                                resolve({method: "datahttp.getData", success: true, data: str});
                        }
                    }
                    catch(error) {
                        rejectPromise(reject, error, "datahttp.getData");
                    }
                }
                else {
                    rejectPromise(reject, {message: response.statusMessage + " (" + response.statusCode + ")"}, "datahttp.getData");
                }
            });

            response.on("error", function(error) {
                rejectPromise(reject, error, "datahttp.getData");
            });
        }

    });
}

我一直在为此奋斗几天，显然只是没有看到一些非常明显的东西，一些帮助和一个上升的头部将受到欢迎
