使用nodejs實現OData的batch操作在Marketing Cloud裡讀取contact資訊

我們先來看看Marketing Cloud系統裡的contact資訊：
一共1218374條資料。

我們用如下的nodejs程式碼透過OData來獲取這些資料：

var request = require('request');var config = require("./mcConfig");var url = config.getContactBatchURL;var sBody = "--batch_c914-a60c-1877" + "\n" + 
"Content-Type: application/http" + "\n" + 
"Content-Transfer-Encoding: binary" + "\n" + 
"\n" + 
"GET InteractionContacts?sap-client=100&$skip=0&$top=2&$select=ImageURL%2cName%2cContactLevelName%2cCountryName%2cCity%2cEMailAddress%2cPhoneNumber%2cMobilePhoneNumber%2cCorporateAccountName%2cInteractionContactUUID%2cRelationship%2cType&$inlinecount=allpages HTTP/1.1" + 
"sap-cancel-on-close: true" + "\n" + 
"Cache-Control: max-age=360" + "\n" + 
"sap-contextid-accept: header" + "\n" + 
"Accept: application/json" + "\n" + 
"Accept-Language: en" + "\n" + 
"DataServiceVersion: 2.0" + "\n" + 
"MaxDataServiceVersion: 2.0" + "\n" + 
"\n" + "\n" + 
"--batch_c914-a60c-1877--";var getContactOptions = {        url: url,        method: "POST",        json:false,        headers: {            "content-type": "multipart/mixed;boundary=batch_c914-a60c-1877",            'Authorization': 'Basic ' + new Buffer(config.user + ":" + config.password).toString('base64')
        },        body: sBody
};function getContact() {  return new Promise(function(resolve,reject){      var requestC = request.defaults({jar: true});      console.log("Step1: get contact via url: " + url );
      requestC(getContactOptions,function(error,response,body){        if( error){          console.log("error occurred: " + error);
          reject(error);
        }        console.log("response:" + body);        var nStartIndex = body.indexOf("{");        var nLastIndex = body.lastIndexOf("}");        if( nStartIndex < 0 || nLastIndex < 0)            return;        var sPayload = body.substring(nStartIndex, ++nLastIndex);
        resolve(JSON.parse(sPayload));
      }); 
     });
}function displayResult(oResult){  console.log(oResult);
}
getContact().then(displayResult);
