how to call api in angular

                           Api Call in service file

Making API calls is a common task in Angular applications, and it can be achieved using Angular's built-in HttpClient service. Here are the steps to make API calls in Angular:

1. Import the HttpClient module: You need to import the HttpClientModule in your app.module.ts file.

import { HttpClient, HttpHeaders } from '@angular/common/http';


2. Create a service: Create a new service to handle the HTTP requests. In this service, you can create methods to handle different types of requests (GET, POST, PUT, DELETE, etc.). Here's an example of a service:

export class ApiService {

    apiUrl = 'https://jsonplaceholder.typicode.com';
 
    constructor(private http: HttpClient) { }
 
    getPosts(): Observable<any[]> {
      return this.http.get<any[]>(`${this.apiUrl}/posts`);
    }
 
    getPostById(id: number): Observable<any> {
      return this.http.get<any>(`${this.apiUrl}/posts/${id}`);
    }
 
    addPost(post: any): Observable<any> {
      return this.http.post<any>(`${this.apiUrl}/posts`, post);
    }
 
    updatePost(id: number, post: any): Observable<any> {
      return this.http.put<any>(`${this.apiUrl}/posts/${id}`, post);
    }
 
    deletePost(id: number): Observable<any> {
      return this.http.delete<any>(`${this.apiUrl}/posts/${id}`);
    }
  }

import { HttpClient, HttpHeaders } from '@angular/common/http';

import { Observable } from 'rxjs';



const API_URL = 'https://dev-eastus2-alphat-win-app.azurewebsites.net/api/';



const httpOptions = {

  headers: new HttpHeaders({ 'Content-Type': 'application/json' })

};



constructor(private http: HttpClient) { }



  register(data:any): Observable<any> {

    return this.http.post(API_URL + 'CreateClinic', data, httpOptions);

  }

  vet_register(data:any): Observable<any> {

    return this.http.post(API_URL + 'RegisterClinicUser', data, httpOptions);

  }

  getClinicCodeCheck(clinicCode:any): Observable<any> {

    return this.http.get(API_URL + 'GetClinicUserInfoByInvitationCode?InvitationCode='+clinicCode, { responseType: 'text' });

  }

  getMasterData(uids:any): Observable<any> {

    return this.http.get(API_URL + 'GetAllMasterData/'+uids, { responseType: 'text' });

  }


  

 forgotPassword(data:any) {

        return this.http.post(API_URL + 'UpdateUserPassword', data, httpOptions);

 }

Component.ts file


import{TestService}from './services/test.service'


constructor(private testservice:TestService){}

resultdata:any;


 ngOnInit() {

   this.testservice.sendGetRequest().subscribe((data)=>{

   this.resultdata=data;

    console.log(this.resultdata)

  })

}




   constructor(
        public http: HttpClient, private config: ConfigService
    ) {

        this.config.Data.subscribe((data) => {
            if (data != '') {
                this.envInfo = data;
                this.baseUrl = this.envInfo.apiURL;
            }
        })

        this.options = {
            headers: new HttpHeaders({
                Accept: 'application/json',
                Authorization: 'Bearer ' + localStorage.getItem('access_token'),
            })
        };
    }



    postData(url: any, formData: any) {
        let apiUrl = this.baseUrl + url;
        this.dataCaching();
        return this.http.post(apiUrl, formData, this.options).pipe(map(res => res))
    }

    getData(url: any) {

        let apiUrl = this.baseUrl + url;
        this.dataCaching();
        return this.http.get(apiUrl, this.options).pipe(map(res => res));
    }

    putData(url: any, formData: any) {
        let apiUrl = this.baseUrl + url;
        this.dataCaching();
        return this.http.put(apiUrl, formData, this.options).pipe(map(res => res));
    }


    downloadData(url: string) {
        const apiUrl = this.baseUrl + url;
        this.dataCaching();
        return this.http.get(apiUrl, this.options1).pipe(map(res => res));
    }

    downloadPost(url: string, formData: any) {

        const apiUrl = this.baseUrl + url;
        this.dataCaching();
        return this.http.post(apiUrl, formData, this.options1).pipe(map(res => res));

    }

    authVerification(url:any, formData:any,options:any) {
        let apiUrl = this.baseUrl + url;
        this.dataCaching();
        return this.http.post(apiUrl, formData, options).pipe(map(res => res));
      }
