angular - 使用 Angular 在 HTTP 调用中获取表单数据

问题描述

This is how the authentication is supposed to be.

POST https://DomainName/api/v1/authentication?username= {username}&password={password}.. 这是打字稿认证调用代码

authenticate(url, payload){
let username: string = 'admin';
let password: string = 'password';
let headers: Headers = new Headers();
  headers.append("Authorization", "Basic " + btoa(username + ":" + password)); 
  headers.append("Content-Type", "application/json");
  headers.append("Access-Control-Allow-Origin", "*");
return this.http.post(server + url + addon, payload, { headers:headers });

这是表单数据的代码

    // Getting data info from signing form
loginForm = new FormGroup({
username: new FormControl(null, ([Validators.required, Validators.minLength(5)])),
password: new FormControl(null, ([Validators.required, Validators.minLength(5)])),
})

用户数据

// user data 
loginData={
username:'',
    password:'',
}

buildLoginData(){
    this.loginData.password = this.loginForm.controls['password'].value;
this.loginData.username = this.loginForm.controls['username'].value;
}

登录功能

    signin(){
    this.loading =this.loadingCtrl.create({
  content:"Verifying Credentials ..."
});
this.loading.present();
    this.buildLoginData();
    console.log(this.loginData);
  this.http.store('authentication', this.loginData).subscribe((response)=>{
            // console.log(response);
            // console.log("*******************************************");
            // console.log(response['username']);
            localStorage.setItem('office_ID',response['officeId']);
            localStorage.setItem('user_ID', response['userId']);
            localStorage.setItem('username', response['username']);
            this.loading.dismissAll();
            this.navCtrl.push(HomePage);
  },error=>{
            this.loading.dismissAll();
                if(error.status === 401){
                    this.toastr.messenger('Wrong Username or Password');
                }else
    this.toastr.messenger('Login Failed!');
            console.log(JSON.stringify(error));
            alert("Error : " + error );
});    
}

响应日志数据

{"_body":"{\"developerMessage\":\"Invalid authentication details were 
passed in api request.\",\"httpStatusCode\":\"401\",\"defaultUserMessage 
\":\"Unauthenticated. Please login.\",\"userMessageGlobalisationCode
\":\"error.msg.not.authenticated\",\"errors
\":[]}","status":401,"ok":false,"statusText":"Unauthorized","headers":
{"Content-Type":["application/json"]},"type":2,"url":"https//x.x.x.x:xxxx            
/xxxxxxxxx/api/v1/authentication?tenantIdentifier=default"}

错误

 "Unauthorized" and this is because the form values are not being sent to                                                                                     
  the api as headers.

任何帮助深表感谢。谢谢。
