SyntaxError：ionic 2中位置3处的JSON中的意外令牌

Question

我在Ionic 2“syntaxerror：uncurrent token

下面是我的Spring Boot代码。

@RequestMapping(value="/myview", method=RequestMethod.GET, produces = "application/json")
    @ResponseBody
    List<Client> myView( @ModelAttribute("client") Client client){


        List<Client> data=(List<Client>) clientService.getAll();


        return data;
    }

import { Injectable } from '@angular/core';
import { Http } from '@angular/http';
import 'rxjs/add/operator/map';


@Injectable()
export class PeopleService {
  people: any;

  constructor(public http: Http) {}

load(){

    if (this.people) {

  return Promise.resolve(this.people);

  }

 return new Promise(resolve => {
    this.http.get('http://localhost:8080/myview')
    .map((res)=>res.json()).subscribe((data)=>{
       console.log(data);
       this.people=data;
       resolve(this.people);
     }, err=>{console.log(err)});
  });
}// end load function

}

[{“ID”：1,“用户名”：“[e-mail]”,“策略”：“v121293031”,“名称”：“唐纳德”,“移动”：“0504735260”,“电子邮件”：“[e-mail]”,“地址”：“Dafza dubai”,“金额”：800.98,“datetimestamp”：1472861297000},{“ID”：3,“用户名”：“[e-mail]”,“策略号”：“v38998933”,“fname”：“唐纳德”,“移动”：“0501234567”,“电子邮件”：“[e-mail]”地址：“MetDubai”,“金额”：334.34,“DateTimeStamp”：1472862939000},{“ID”：4,“用户名”：“[e-mail]”,“政策号”：“v34342323”,“fname”：“史努比”,“移动”：“0501234567”,“电子邮件”：“[e-mail]”,“地址”：“MetLife Dafza Dubai”,“金额”：883.43,“DateTimeStamp”：1472916463000}]

我的http://localhost:8080/MyView不起作用，因为当我使用数组值尝试下面的代码时，它起作用了。如何调用http而不是将静态值放在数组中？

import { Injectable } from '@angular/core';
import { Http } from '@angular/http';
import 'rxjs/add/operator/map';


@Injectable()
export class PeopleService {

  people: Array<any> = [{"id":1,"username":"[e-mail]","policyno":"V121293031","fname":"Donald","mobile":"0504735250","email":"[e-mail]","address":"Dafza Dubai","amount":800.98,"datetimestamp":1472861297000},{"id":3,"username":"[e-mail]","policyno":"V38998933","fname":"Donald","mobile":"0501234567","email":"[e-mail]","address":"MetLife Dubai","amount":334.34,"datetimestamp":1472862939000}];


  constructor(private http: Http) {}

load(){

    if (this.people) {

  return Promise.resolve(this.people);

  }

 return new Promise(resolve => {

    this.http.get('http://localhost:8080/myview')
    .map((res)=>res.json())
    .subscribe((data)=>{
       this.setPeople(data);
       resolve(this.people);
     });
  });
}// end load function

setPeople(data) {
      if (data) {
        for (let id of Object.keys(data)) {
          let item = data[id];

          item.id = id;

          this.people.push(item);
        }
      }
    }

}

对/myview的调用将返回不正确的JSON。它必须有HTML元素。执行res.json（）从响应的_body中提取数据（如果有效的话）。但在您的情况下，它引发了一个错误。
