I am trying to fetch details. So, here is my code.
data.service.ts
import { Injectable } from '@angular/core';
import { Http, Headers } from '@angular/http';
import 'rxjs/add/operator/map';
import { HttpClient,HttpErrorResponse } from
'@angular/common/http';
import { ActivatedRoute, Router } from '@angular/router';
export class DataService {
constructor(private http: HttpClient) {}
userdetails() {
return this.http.get(`http://jsonplaceholder.typicode.com/users`);
}
}
home.component.ts
import { Component, OnInit } from '@angular/core';
import { DataService } from '../data.service';
import { ActivatedRoute, Router } from '@angular/router';
import { HttpClient } from '@angular/common/http';
import { userInfo } from 'os';
@Component({
selector: 'app-home',
templateUrl: './home.component.html',
styleUrls: ['./home.component.css']
})
export class HomeComponent implements OnInit {
user:any
constructor(private data: DataService) { }
ngOnInit()
{
this.data.userdetails().subscribe(
allData => {
this.user = allData;
return this.user;
});
}
}
home.component.html
<div *ngFor="let x of allData">
{{{x.name}}
</div>
<router-outlet></router-outlet>
I am getting some syntax error in home.component.ts and other error like "Can't resolve all parameters for DataService: (?)." . Please help me guys.
You can try code below or seen: API IN ANGULAR 7
File servive when request API, you need add
const httpOptions = {
headers:new HttpHeaders({'Content-Type':'application/json'})
};
/*
* METHOD POST
*/
sendpost(value: any) {
return this.http.post<any>('http://jsonplaceholder.typicode.com/posts', value,httpOptions)
.pipe(map(user => {
return user;
}));
}
/**
* METHOD GET
*/
getdetails(){
return this.http.get<any>('http://jsonplaceholder.typicode.com/users')
.pipe(map(item => {
return item;
}));
}
------------------------------------------------------------------------------------------------
File HomeComponent.ts: you import file serivice
import {UserService} from '../_services/user.services'
dataItem:any = {}
constructor(private _userService:UserService){
this._userService.getdetails().subscribe(item=>{
console.log(item);
this.dataItem=item;
})
}
------------------------------------------
show HomeComponent.html
<ul *ngIf="dataItem?.length>0">
<li *ngFor='let item of dataItem'>
{{item.name}} - {{item.username}}
</li>
</ul>
