Error data.forEach不是函数（如何提取对象的Json对象）

我正在处理一个angular项目，我必须从一个JSON对象获取数据，在正常情况下，我将创建一个类，例如'fake.ts'来获取和访问正确的值，但这里我有一个JSON，它包含4个其他对象，如：

{
  "GetUIDriverManagementParamResult": {
    "AccessRightsOfCurrentAccount": [{
      "Key": "3",
      "Value": "Gestion des comptes"
    }, {

好吧，我试着做一个这样的类：

export interface Drivermanager{
AccessRightsOfCurrentAccount: any;
ConnectionInfo: any[];
CurrentAccount: any[];
ListDepartment: any[];
ListDriverElement: any[];
}

并通过以下方式获取数据：

  this._documentmanagmentService.getDriverMAnnager().subscribe((data: Drivermanager[])=>{
    console.log(data);
    data.forEach(element => {
      console.log(element.CurrentAccount); 
   });
});

但我得到了：

错误类型错误：data.forEach不是函数

那个么伙计们，例如，我如何将代码更改为从ListDriveRelation访问地址呢

---

请大家帮忙

据我所知，您希望得到这样的答复。因此，您可以使用

Object.entries

并在此基础上使用

foreach

。这将为您提供所需的结果

  this._documentmanagmentService.getDriverMAnnager().subscribe((data)=>{
    Object.entries(data.ListDriverElement).forEach(([key,value]) => {
     console.log(value);
   });
});

假设你有这样的数据

    let data = {
      AccessRightsOfCurrentAccount: null,
      ConnectionInfo: [],
      CurrentAccount: [],
     ListDepartment: [],
     ListDriverElement: [{Address: "", BirthDateLocal: null, BirthPlace: ""}, 
    {Address: "", BirthDateLocal: null, BirthPlace: ""}]
 }

---

从API获取值时，不必提供类型。要获取嵌套对象

CurrentAccount

，可以尝试以下操作

this.\u documentmanagementservice.getDriverManager（）.subscribe(
（数据）=>{//{
console.log（accessRight）；
});

您无法获得多个

CurrentAccount

s，因为在您提供的对象中只有一个

CurrentAccount

，其中包含的

AccessRights

是一个数组

---

另外，如果您没有在订阅中分配类型，请不要在

getDriverManager（）中分配类型

服务中的函数。

不是一个有效的JSON结构。只是一个示例而已。我需要知道如何访问对象的对象。您是从本地文件还是从api获取JSON？并且将JSON更改为clean JSON，以便从api清楚地理解，我将显示结果图像我们在屏幕截图中看不到驱动程序在哪里您提供了。请向我们提供正确的数据，以便我们能够理解和解决我需要提取数据以避免在其上插入空对象的问题it@omarbouhajja，是的，我知道试试这个，它会起作用的。请阅读有关

对象的详细信息。条目

但它不起作用。值有{地址：“”，BirthDateLocal:null，出生地：“”，{地址：，出生日期本地：null，出生地：}作为result@SRana你能帮我吗！@omarbouhajja，你到底想要什么？根据你之前的问题，你想要访问DriverListent。
