Ionic 2 Json解析

Question

我如何解析json数据

数据=“ {\\” msg_ok \\“：\\” Uye olusturuldu \\“，\\” user_id \\“：181，\\” token \\“：\\” 8650bfe987a3d619445f3d4905e1ae863e4be85f \\“}”

我想使用令牌数据

我试过像这样的代码，但无法正常工作。

感谢现在

var headers = new Headers();
headers.append('Accept', 'application/json');
headers.append('Content-Type', 'application/json' );  
//headers.append('Authorization' , 'Basic '+ btoa(tok));
let options = new RequestOptions({ headers: headers });

let postParams = {
  username: this.uyelik['username'],
  email:this.uyelik['email'],
  password:this.uyelik['password']
}

this.http.post("https://deneme.com/api/v1.0/users/", postParams, options)
  .subscribe(data => {
     console.log(data['_body']);
     this.veri = data['_body'];
    this.veri = JSON.parse(this.veri);
     console.log(this.veri['token']);
   }, error => {
    console.log(error);// Error getting the data
  });

我解决了问题;

var headers = new Headers();
    headers.append('Accept', 'application/json');
    headers.append('Content-Type', 'application/json' );  
    //headers.append('Authorization' , 'Basic '+ btoa(tok));
    let options = new RequestOptions({ headers: headers });

    let postParams = {
      username: this.uyelik['username'],
      email:this.uyelik['email'],
      password:this.uyelik['password']
    }

    this.http.post("https://iothook.com/api/v1.0/users/", postParams, options)
      .subscribe(data => {
         //console.log(data['_body']);
        veri = data['_body'];

        veri= veri.slice(1, -1);
        veri = veri.replace(/\\/g, "");
        veri = JSON.parse(veri);
        console.log(veri.token);


       }, error => {
        console.log(error);// Error getting the data
      });

尝试这个。

this.http.post("https://deneme.com/api/v1.0/users/", postParams, options)
        .map((res: Response) => res.json())
          .subscribe(data => {
             console.log(data['_body']);
             this.veri = data['_body'];
            this.veri = JSON.parse(this.veri);
             console.log(this.veri['token']);
           }, error => {
            console.log(error);// Error getting the data
          });

像这样解析-

 var a = '{\\"msg_ok\\": \\"Uye olusturuldu\\", \\"user_id\\": 181, \\"token\\": \\"8650bfe987a3d619445f3d4905e1ae863e4be85f\\"}'; a.replace(/\\//g, ""); var token = JSON.parse(a).token; console.log(token)
