Ionic 2 Json parse

Question

如何解析 json 数据

data = "{\"msg_ok\"： \">

Uye olusturuldu\"， \"user_id\"： 181， \"token\"： \"8650bfe987a3d619445f3d4905e1ae863e4be85f\"}">

我想使用令牌数据

我尝试过像这段代码，但不起作用。.

感谢到现在

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
});

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
});

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)
