离子2的Json解析

数据= “{\” MSG_OK \ “：\” 初级会员olusturuldu \ “\ ”USER_ID \“：181，\ ”令牌\“：\” 8650bfe987a3d619445f3d4905e1ae863e4be85f \ “}”

我想用令牌数据

我想这样的代码，但没有工作..

感谢名单到现在

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 
     });

做映射。像这样的东西返回this.http.post（this.baseUrl + endUrl，param，options） .map（（res：Response）=> res.json（））; –

嗯，我的代码是在旁边工作？ –

试试这个。

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 
      });

解析像这个 -

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