Question

这是我的JSON文件的样子：

   {
    "responseCode": 200,
    "responseMessage": "" , 
    "details": "{\"id\":1,\"name\":\"sss\",\"status\":\"status 1\",\"active\":true,\"createdAt\":\"Dec 4, 2019, 4:21:46 PM\",\"modifiedAt\":\"Dec 5, 2019, 10:21:09 AM\",\"description\":\"daddddddddddddd\",\"imagePath\":\"imagepath 1\",\"viewCount\":133,\"important\":1}",
    "timestamp": 0
}

TS文件：

ngOnInit() {
this.blog.getBlog(this.id).subscribe((data: {}) => {
  this.blogData = JSON.parse(data['details']);
})
  } 
   updateBlog() {
if(window.confirm('Are you sure, you want to update?')){
  this.blog.UpdateBlog(this.id, this.blogData).subscribe(data => {
    this.router.navigate(['/home/blogger'])
  })
}
}

服务文件：

UpdateBlog(id,blog): Observable<Blog> {
  let body = JSON.stringify(blog);
  console.log(blog)
  return this.http.put<Blog>('blog/' + id, body, this.httpOptions)
  .pipe(
    retry(1),
    catchError(this.handleError)
  )
}

我可以执行诸如获取，删除和创建之类的操作，但无法将值更新为以下JSON格式。

下面是send选项下的邮递员代码：

 {

        "name": "sss",
        "description": "Thsh",
        "imagePath": "imagepath 1",
        "status": "status 1",
        "active": true
 }

如何将数据更新到angular中的嵌套数组？
