问题描述
我有一个简单的Angular表单,我想将Loan
对象发布到.net核心Web API.
I have a simple Angular form which I want to post a Loan
object to a .net core web API.
提交表单后,我可以在控制台中看到以下数据:
After submitting the form I can see this data in the console:
对象{ID:0,BorrowerName:"asd",RepaymentAmount:11.5,FundingAmount:10}
Object { Id: 0, BorrowerName: "asd", RepaymentAmount: 11.5, FundingAmount: 10 }
但是我的API操作从未被调用.
But my API action never gets called.
我在做什么错了?
Api Action
[HttpGet]
public ActionResult<IEnumerable<Loan>> Get()
{
return _context.Loans;
}
Loan.cs
public class Loan
{
[Key]
[DatabaseGenerated(DatabaseGeneratedOption.Identity)]
public int Id { get; set; }
public string BorrowerName { get; set; }
public decimal RepaymentAmount { get; set; }
public decimal FundingAmount { get; set; }
}
贷款表格.component.ts
import { Component, OnInit } from '@angular/core';
import {HttpClient} from '@angular/common/http';
import { Loan } from '../loan';
@Component({
selector: 'app-loan-form',
templateUrl: './loan-form.component.html',
styleUrls: ['./loan-form.component.css']
})
export class LoanFormComponent implements OnInit {
model = new Loan(0, "", 0, 0);
constructor(private http:HttpClient) { }
ngOnInit() {
}
setRepaymentAmount(event) {
this.model.RepaymentAmount = event * 1.15;
}
onSubmit() {
console.log(this.model);
var config = {
headers : {
'Content-Type': 'application/json;charset=utf-8;'
}
}
this.http.post('http://localhost:1113/api/loans', this.model, config);
}
}
loan-form.component.html
<div class="container">
<h1>New Loan Form</h1>
<form (ngSubmit)="onSubmit()" #loanForm="ngForm">
<div class="form-group">
<label for="BorrowerName">Borrower Name</label>
<input type="text"
class="form-control"
id="BorrowerName"
required
[(ngModel)]="model.BorrowerName" name="BorrowerName"
#spy>
</div>
<div class="form-group">
<label for="FundingAmount">Funding Amount</label>
<input type="number" class="form-control" id="FundingAmount" required
[(ngModel)]="model.FundingAmount" name="FundingAmount"
(ngModelChange)="setRepaymentAmount($event)"
#spy>
</div>
<div class="form-group">
<label for="RepaymentAmount">Repayment Amount</label>
<input type="number" class="form-control" id="RepaymentAmount"
[(ngModel)]="model.RepaymentAmount" name="RepaymentAmount" readonly>
TODO: remove this: {{model.RepaymentAmount}}
</div>
<button type="submit" class="btn btn-success" [disabled]="!loanForm.form.valid">Submit</button>
</form>
</div>
推荐答案
您缺少发帖请求的订阅".
You are missing "subscription" for the post request.
this.http.post('http://localhost:1113/api/loans', this.model, config).subscribe();
