Question

下面是我正在使用的Google应用程序脚本SOAP API信封调用。它可以正常连接，并且您可以在下面看到它返回响应，但是我的响应已编码。如何/在何处添加一点以进行Base64解码以查看返回的XML而不是字符串？我对SOAP API完全陌生，对应用程序脚本还是新手。谢谢！

function getData() { 
var webservice = ‘https://someplace.com/services/stuff/’;

var xml = '<soapenv:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ser="http://someurlhere.com">'
+   '<soapenv:Header/>'
+   '<soapenv:Body>'
+ '<ser:getReportXML soapenv:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"> '
+    '<in0 xsi:type="soapenc:string" xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/">' +  userid + '</in0> '
+    '<in1 xsi:type="soapenc:string" xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/">' + password + '</in1> '
+    '<in2 xsi:type="soapenc:string" xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/">' + startDate + '</in2> '
+    '<in3 xsi:type="soapenc:string" xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/">' + endDate + '</in3> '
+ '</ser:getReportXML> '
+   '</soapenv:Body>'
+' </soapenv:Envelope>'

var options = {  
  headers: {"SOAPAction" :"https://someplace.com/services/stuff/"},
  method: "post",
  contentType: "text/xml",
  payload: xml,
  muteHttpExceptions: true,
};

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

};

它在响应中返回一个编码字符串，但是我想查看实际的XML结果：



[19-01-31 11:46:02:122 PST] <?xml version="1.0" encoding="UTF-8"?><soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"><soapenv:Body><ns1:getReportXMLResponse soapenv:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" xmlns:ns1=" http://someurlhere.com "><getReportXMLReturn xsi:type="soapenc:base64Binary" xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/">WMui8xyxcPQXmZgSerdPd94bwWxGsAMgdmVyc2lvbj0iFRxlTSerdgiPz4NCg0KPQFET0NUW

我正在尝试使响应输出看起来像xml而不是一串字符

<?xml version="1.0" encoding="utf-8"?>

<!DOCTYPE ETRANS PUBLIC "-//Something//ethings DTD//EN" "https://www.url.com/dtd/ethings_1_0.dtd">

<ETRANS>
<USER ID="AABB1122" USER_NAME="Smith, John" DATE="2019-02-01 09:41:45" DEPT_ID=""/>
</ETRANS>

所以我发现我的响应确实具有XML的编码主体，但是在实际编码的数据之前，响应中还具有所有这些额外的位，因此解码器失败了，因为它不知道如何处理响应开头显示在此处

[19-01-31 11:46:02:122 PST] <?xml version="1.0" encoding="UTF-8"?><soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"><soapenv:Body><ns1:getReportXMLResponse soapenv:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" xmlns:ns1=" http://someurlhere.com "><getReportXMLReturn xsi:type="soapenc:base64Binary" xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/">

，以及底部的一些其他位，类似于上述位的结尾。我是否需要传递某些请求，以使SOAP请求仅返回字符串，而不是这些多余的位（看起来像是在将“信封”放在要发送回的编码数据周围）？

我终于想通了。我不知道是否有一种“更好”的方式来做到这一点，但是如果您看到我所做的，也许您可能会分享这种“更好”的方式。所以我在下面添加了“ NEW BIT”行。为了解码base64位，我不得不放弃SOAP Envelop。我可以在Google Apps脚本中弄清楚的唯一方法是将响应另存为文件，因为这似乎在“神奇地”消除了SOAP。因此，我必须获取我创建的MyTestFile文件中剩下的base64位，并将其解码为文本字符串，然后解码/转换它，然后创建了我要查找的xml。我希望这可以帮助其他人。

function getData() { 
    var webservice = ‘https://someplace.com/services/stuff/’;
    var newDocName = 'MyTestFile'

    var xml = '<soapenv:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ser="http://someurlhere.com">'
    +   '<soapenv:Header/>'
    +   '<soapenv:Body>'
    + '<ser:getReportXML soapenv:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"> '
    +    '<in0 xsi:type="soapenc:string" xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/">' +  userid + '</in0> '
    +    '<in1 xsi:type="soapenc:string" xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/">' + password + '</in1> '
    +    '<in2 xsi:type="soapenc:string" xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/">' + startDate + '</in2> '
    +    '<in3 xsi:type="soapenc:string" xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/">' + endDate + '</in3> '
    + '</ser:getReportXML> '
    +   '</soapenv:Body>'
    +' </soapenv:Envelope>'

    var options = {  
      headers: {"SOAPAction" :""},
      method: "post",
      contentType: "text/xml",
      payload: xml,
      muteHttpExceptions: true,
    };

    var serviceaddress = webservice;
    var response = UrlFetchApp.fetch(serviceaddress, options).getContentText();
    //Logger.log(response);

    //NEW BIT BEGINS HERE THAT DECODED THE RESPONSE

    var blob = DriveApp.createFile('dummy',response, 'text/html').getBlob();
    var resource = {
      title: newDocName,
      convert: true,
      mimeType: 'application/vnd.google-apps.file'
    };

    var file = Drive.Files.insert(resource,blob);
    var doc = DocumentApp.openById(file.id);
    var text = doc.getBody().getText();

    var decoded = Utilities.base64Decode(text,Utilities.Charset.UTF_8);  // This was a byte array
    var decodedstr = Utilities.newBlob(decoded).getDataAsString()  // This was the xml I was looking for
    Logger.log(decodedstr);
    //NEW BIT ENDS HERE 
};

Google Apps Script SOAP响应已编码。如何/在何处添加base64decode以将响应视为xml
