如何在谷歌应用程序脚本上调用Web服务

Question

我在SAP中创建了一个Web服务，并尝试从谷歌应用程序脚本调用此SOAP Web服务。

这个WS处于BASIC认证中，在变量响应中，我收到了与传入输入相同的wsdl。 我在后端系统调用中遇到问题“收到不支持的内容类型：”“ 有人可以帮帮我吗？

var user = 'user';
var pwd = 'pwd';
var webservice = 'http://xx.xxx.xx.xx:xxxx/sap/bc/srt/wsdl/flv_10002A111AD1/bndg_url/sap/bc/srt/rfc/sap/zdemo_google_ws/100/zdemo_google_ws/zdemo_google_ws?sap-client=100.wsdl';
function readData() {  

//Clean up anything currently on the spreadsheet  
SpreadsheetApp.getActiveSheet().clear();  

try {  

//Various XML parsing.  
var xml = "<soapenv:Envelope xmlns:soapenv=\"http://schemas.xmlsoap.org/soap/envelope/\" xmlns:urn=\"urn:sap-com:document:sap:soap:functions:mc-style\">"

var options = {  
  headers: {  
    "Authorization": "Basic " + Utilities.base64Encode(user + ':' + pwd),
    "method" : "post",
    "contentType" : "text/xml",
    "payload" : xml,
    "muteHttpExceptions":true
  },  
};  

//UrlFetchApp is a powerful built-in library from Google  

var serviceaddress =  webservice ;
var response = UrlFetchApp.fetch(serviceaddress, options);

要使用UrlFetchApp.fetch()，需要修改脚本的option。那么这个修改怎么样？

来自：

var options = {  
  headers: {  
    "Authorization": "Basic " + Utilities.base64Encode(user + ':' + pwd),
    "method" : "post",
    "contentType" : "text/xml",
    "payload" : xml,
    "muteHttpExceptions":true
  },  
};

致：

var options = {  
  headers: {"Authorization": "Basic " + Utilities.base64Encode(user + ':' + pwd)},
  method: "post",
  contentType: "text/xml",
  payload: xml,
  muteHttpExceptions: true,
};

如果这不是您问题的直接解决方案，我很抱歉。
