带有JSON Payload的Google Apps脚本UrlFetchApp

Question

我正在尝试POST一个期望使用Google Apps脚本获取JSON作为有效负载的Web服务.我正在使用以下代码:

var options =
{
  "method" : "post",
  "contentType" : "application/json",
  "headers" : {
    "Authorization" : "Basic <Base64 of user:password>"  
  },
  "payload" : { "endDate": "2012-06-03" }
};

var response = UrlFetchApp.fetch("http://www.example.com/service/expecting/json", options);

在服务器端,我收到以下错误:

WARN [facade.SettingsServlet] 04 Jun 2012 15:30:26 - Unable to parse request body: endDate=2012-06-03
net.liftweb.json.JsonParser$ParseException: unknown token e

我假设服务器期待得到

{ "endDate": "2012-06-03" }

代替

endDate=2012-06-03

但我不知道如何让UrlFetchApp做到这一点.

Answer 1

我不理解服务器端错误,但'payload'参数必须是此处指定的字符串:https://developers.google.com/apps-script/class_urlfetchapp？hl = fr-FR #fetch.

尝试:

var options =
{
  "method" : "post",
  "contentType" : "application/json",
  "headers" : {
    "Authorization" : "Basic <Base64 of user:password>"  
  },
  "payload" : '{ "endDate": "2012-06-03" }'
};
