I have the following problem
[ts] The 'json' property does not exist in the 'Object' type. any
This is the code:
postData(credentials,type){
return new Promise((resolve, reject) =>{
let headers = new HttpHeaders();
this.http.post(apiUrl+type, JSON.stringify(credentials), {headers: headers}).
subscribe(res =>{
resolve(res.json());
}, (err) =>{
reject(err);
});
});
}
If you are using dependency HttpClient it is not necessary to convert to JSON, because the response of the observable is already a JSON.
HttpClient Angular official documentation
For this reason the code should look like this:
public postData(credentials: Object, type: string): Promise<any> {
return new Promise((resolve, reject) => {
this.http.post(apiUrl + type, credentials).subscribe(
response => {
resolve(response);
},
exception => {
reject(exception);
}
);
});
}
