Back4app 解析服务器检索到 ObjectId

Question

嗨，我想知道为什么我无法从此 json 对象检索 objectId，即使我可以在控制台上打印出 stringify。

我可以毫无问题地检索所有其他列，但不能检索 objectId。它发生在我的 back4app Parse 服务器中的所有 table。

我需要 objectId 来更新我程序中的特定列

下面是我的代码

1)

   const parseQuery = new Parse.Query("User");
    parseQuery.equalTo("username", "Azha");
    let queryResult = await parseQuery
      .find()
      .then((results) => {
        results.forEach((prod) => {
//if i change below to prod.get("objectId") error undefined appear
          console.log("Product ID Available : " + prod.get("username"));
     
        });
      })
      .catch((error) => {
        console.log(error);
      });

    const parseQuery = new Parse.Query("User");
    parseQuery.equalTo("username", "Azha");
    try {
      let todos = await parseQuery.find();
      if (todos.length > 0) {
//if i change below to todos[0].get("objectId") error undefined appear
        console.log("yes Approval : " + todos[0].get("companyname"));
      } else {
        console.log("No Approval");
      }
      console.log("- value is : " + JSON.stringify(todos));
      console.log("----------------------");  
    } catch (error) {
  
      Alert.alert("Error!", error.message);
     
    }

下面是 json 打印输出

[{"sessionToken":"r:d9166aa9d7143463c46725d095b53946","username":"Azha","createdAt":"2021-09-21T15:27:01.088Z","updatedAt":"2021-10 -10T13:01:27.126Z","公司名称":"XXX","全名":"XXX","电子邮件":"azha@abc.com.my","emailVerified":true,"访问级别":" Maintenence","companydivision":"Maintenence","position":"Technician","phonenumber":"999","userteam":"B","useremail":"azha@abc.com.my"," ACL":{"*":{"read":true},"IuBGmCtxyu":{"read":true,"write":true}},"objectId":"IuBGmCtxyu"}]

Answer 1

是的，我刚刚找到了我的解决方案。使用下面的对象 1：

   const parseQuery = new Parse.Query("User");
    parseQuery.equalTo("username", "Azha");

    try {
      let todos = await parseQuery.find();
      var object1 = JSON.parse(JSON.stringify(todos));
  
      console.log("2- value is : " + object1[0].objectId);

    
    } catch (error) {

      Alert.alert("Error!", error.message);
 
    }
