如何以这种JSON格式发送Angular 8表单数据？如何构建嵌套JSON以通过HTTP post请求发送？

我的JSON就是这种格式。如何设计一个角度表单组来轻松获取和更新这些数据。我面临的问题是如何为表单组编写一个良好的结构

如果JSON结构复杂，请建议更改

{
usertypes_id: "1",
name: "Admin",
permissions: "{"dashboard":{"name":"Dashboard","value":"Full"},"studioInformation":{"name":"Studio Information","value":"Full"},"studioLocation":{"name":"Studio Location","value":"Full"},"users":{"name":"Users","value":"Full"},"roles":{"name":"Roles","value":"Full"},"dancers":{"name":"Dancers","value":"Full"},
},
{
usertypes_id: "2",
name: "Staff",
permissions: "{"dashboard":{"name":"Dashboard","value":"Full"},"studioInformation":{"name":"Studio Information","value":"Full"},"studioLocation":{"name":"Studio Location","value":"Full"},"users":{"name":"Users","value":"Full"},"roles":{"name":"Roles","value":"Full"},"dancers":{"name":"Dancers","value":"Full"},
}

这是我已经尝试过的

constructor(
    private rolesService: RolesService,
    private menuItems: MenuItems,
    private fb: FormBuilder
  ) {

  }

ngOnInit() {
 const name = this.fb.control("", [Validators.required]);
    const permissions = this.fb.group({
      dashboard: this.fb.group({
        name: ["", Validators.required],
        value: ["", Validators.required]
      }),
      studioInformation: this.fb.group({
        name: ["", Validators.required],
        value: ["", Validators.required]
      }),
      studioLocation: this.fb.group({
        name: ["", Validators.required],
        value: ["", Validators.required]
      }),
      users: this.fb.group({
        name: ["", Validators.required],
        value: ["", Validators.required]
      }),
      roles: this.fb.group({
        name: ["", Validators.required],
        value: ["", Validators.required]
      }),
      dancers: this.fb.group({
        name: ["", Validators.required],
        value: ["", Validators.required]
      }),
      staff: this.fb.group({
        name: ["", Validators.required],
        value: ["", Validators.required]
      }),
      courses: this.fb.group({
        name: ["", Validators.required],
        value: ["", Validators.required]
      }),
      classes: this.fb.group({
        name: ["", Validators.required],
        value: ["", Validators.required]
      }),
    });

    this.roleForm = this.fb.group({
      name: name,
      permissions: permissions
    })
}

你能补充一下你已经试过的吗？@Nicolas这是我试过的。。。不确定though@Nicolas请调查一下，我不知道该怎么回答。我不是角度方面的专家，我觉得我们遗漏了一些信息。您希望根据文件更新json。文件保存在浏览器还是服务器上？如果它在服务器上，您需要一个API来更新它。这不仅仅是您提供的。
