Question

我收到的错误如ERROR SyntaxError: Unexpected token in JSON at position 508。我对此感到困惑，请帮助我，我在哪里出错。

这是getpack函数：

getpacks(): Packs[] {
this.dataSource.getpacks().subscribe(packList => this.packList = packList);
  console.log('"repository"');
  console.log(this.packList);
  console.log(JSON.parse(JSON.stringify(this.packList))) ;
return this.packList;

这是http调用函数：

 getpacks(): Observable<Packs[]> {
    console.log('rest');
       return this.http.request(new Request({
         method: RequestMethod.Post,
         url: '/Dev/getPack',
         body: {
          'ownerID': 1001,
          'outputMsgFlag' : '',
          'outputMSg' : ''
        },
         headers: this.headers,
       })).map(response => response.json());
     }

这是获取值并分配给packList的函数：

   get packList(): Packs[] {

        return this.repository.getpacks();

      }

这是我的JSON：

{
    "packList": [
        {
            "pack_id": 1,
            "pack_name": "Bangalore Janapriyaa",

            "comments": "My name is Scott Chow\r"
        },
        {
            "pack_id": 2,
            "pack_name": "Vijaynagar Janapriya",
            "pack_type": "base pack",
            "base_price": 128,
            "cgst_amount": 11.52,
            "sgst_amount": 11.52,
            "total_tax": 23.04,
            "total_amount": 151.04,
            "active": "Y",
            "created_on": "2017-01-05 04:18:00.0",
            "created_by": "Abhishek",
            "owner_id": 1001,
            "modified_on": "2017-06-14 11:51:00.0",
            "modified_by": "Zoombox",
            "disabled_on": "",
            "comments": "and I am going to be your guide on this journey to building a successful blog. I have been building blogs and websites since 2002.\r"
        }
    ]
}

我收到这样的错误。请检查并告诉我任何解决方案：

不确定位置508在哪里，但我猜你的回答是无效的。您应该返回JSON.stringify(this.packList)。不只是this.packlist

您可以在浏览器中点击F12 ，在网络标签中查看您的回复。
