javascript - Parse.com 日志不断返回字符串为 [object Object]

Question

在我下面的云代码中，我试图将变量 leanBody 设置为等于某个字符串，但它一直返回一个奇怪的数组 [object Object]。我不知道它为什么这样做。在我努力调试并找到该数组的设置位置时，我尝试过（单独）：

• 在全局声明中设置leanBody等于任意字符串
• 然后我尝试将其设置为 varReset 函数中的任意字符串
• 然后我什至注释掉了leanBody = (results.get("messageBody")); 在 afterSave 函数中

我仍然不断收到一条日志，说它等于 [object Object]。

  var leanBody = "";
  var leanSenderName = "";
  var leanSenderId = "";
  var randUsers = [];

function varReset(leanBody, leanSenderName, leanSenderId, randUsers){
   leanBody = "";
   leanSenderName = "";
   leanSenderId = "";
   randUsers = [];
   console.log("The variables were set");
}


Parse.Cloud.afterSave("Lean", function(leanBody, leanSenderName, leanSenderId, randUsers, request) {
  varReset(leanBody, leanSenderName, leanSenderId, randUsers);

  var leanQuery = new Parse.Query("Lean");
  leanQuery.first({
    success: function(leanBody, results){
      console.log("The first object was retrieved");
      console.log("leanBody = " + leanBody);
      leanBody = (results.get("messageBody"));
    }, error: function(error){
    }

  });
});
