从HANA XSJS调用出站服务-读取响应时连接丢失

Question

我正在关注以下博客，以从XSJS调用示例服务。

OData CRUD from XSJS

我的样本服务

Sample Service URL

这是我的代码

var destination_package = "destPkg";
var destination_name = "dummydest";
var destination;
var client;
var request;
var employeeID;

try{
    //Reading the destination properties
    destination = $.net.http.readDestination(destination_package,destination_name);
    //Creating HTTP Client
    client = new $.net.http.Client();
    //Creating Request
    request = new $.web.WebRequest($.net.http.GET,"");
    client.request(request,destination);
    //Getting the response body and setting as output data
    $.response.setBody(client.getResponse().body.asString());
}
catch(errorObj){
  $.response.setBody(JSON.stringify({
  ERROR : errorObj.message
  }));
}

我的目的地

host = "postman-echo.com";
port = 443;
pathPrefix = "/get?foo1=bar1&foo2=bar2";
proxyType = none;
proxyHost = "";
proxyPort = 0;
authType = none;
useSSL = false;
timeout = 0;

一旦我测试了XSJS，它会给出以下错误

  

{“ ERROR”：“ HttpClient.getResponse：无法从   服务器：IPCon错误：\“到postman-echo.com的连接丢失，同时   阅读响应。\“”}
