Paytm 集成在 angular C# .net core api 项目中不起作用

问题描述

我无法在我的 C# .net 核心项目中集成 Paytm 网关。我正在接受一些处理并得到这个

Cannot POST /payment
@H_404_4@

我做了以下编码

在Paymnt-gateway.component.html我有一个简单的按钮

<button type="button" (click)="submitForm()">PAY Now</button>
@H_404_4@

在 Paymnt-gateway.component.ts 文件中我有这个代码

export class PaymentGatewayComponent implements OnInit {
     paytm: any;
     ngOnInit(): void {
     
  }

  submitForm() {

      submitForm() {
  // I will do API call and will get CHECKSUMHASH.
  //this.http.post('https://myAPI.com/createchecksum',this.paytm)
  //  .subscribe((res: any) => {
  //    // As per my backend i will get checksumhash under res.data
  //    this.paytm['CHECKSUMHASH'] = res.data;
  //    // than i will create form
  //    this.createPaytmForm();
  //  });

debugger;

let userId = localStorage.getItem('u-id');
let method = "payment/" + userId;
let data = "";

this.dataservice.postFeed(method,JSON.stringify(data)).subscribe(result => {
  debugger;

  if (result.body.success == false) {

  }
  else {

    let userId = localStorage.getItem('u-id');

    this.paytm = {
      MID: "my MID here",// paytm provide
      WEBSITE: "WEBSTAGING",// paytm provide
      INDUSTRY_TYPE_ID: "Retail",// paytm provide
      CHANNEL_ID: "WEB",// paytm provide
      ORDER_ID: "AWS10007",// Math.floor(10000000000 + Math.random() * 90000000000),CUST_ID: userId,// customer id
      MOBILE_NO: "9809234011",// customer mobile number
      EMAIL: userId,// customer email
      TXN_AMOUNT: "1.00",// transaction amount
      CHECKSUMHASH: result.body.data,CALLBACK_URL: "http://localhost:4200/paymentstatus",// Call back URL that i want to redirect after payment fail or success
    };

    //this.paytm['CHECKSUMHASH'] = result.body.data;
    //this.paytm = result.body.data;
    this.createPaytmForm();
  }
});
 }
  }

  createPaytmForm() {
const my_form: any = document.createElement('form');
my_form.name = 'paytm_form';
my_form.method = 'post';
my_form.action = 'https://securegw-stage.paytm.in/order/process';

const myParams = Object.keys(this.paytm);
for (let i = 0; i < myParams.length; i++) {
  const key = myParams[i];
  let my_tb: any = document.createElement('input');
  my_tb.type = 'hidden';
  my_tb.name = key;
  my_tb.value = this.paytm[key];
  my_form.appendChild(my_tb);
};

  document.body.appendChild(my_form);
  my_form.submit();
}
@H_404_4@

在后端服务 api 中，我有代码来生成 checksumhash 像这样

    [HttpPost("{uid}")]
    [ProducesResponseType(typeof(int),200)]
    [ProducesResponseType(typeof(int),400)]
    [ProducesResponseType(typeof(string),500)]
    public async Task<IActionResult> Post(string uid)
   {
   string body = @"{'\mid\':'\MID here\','\orderId\':'\AWS10007\'}";

   string paytmChecksum = Paytm.Checksum.generateSignature(body,"%my key here");

   response.Data = paytmChecksum;
@H_404_4@

使用这里的响应假设像 checksumhash

我在这里做错了什么？

解决方法

您似乎正在集成已弃用的 Paytm 重定向流，我们建议集成 js 结帐解决方案。文档可在 paytm 开发者门户上找到。
