我在 Angular 4 中集成 paytm。paytm 插件已成功添加到项目中，但我不知道如何在 ts 文件中导入 paytm 插件。并调用java文件文件函数。

请帮助我...这是我的代码

import { Nav, Platform } from 'ionic-angular';
import { Component, OnInit } from '@angular/core';
import { NavController } from 'ionic-angular';
import {} from 'jasmine';
import {LoginPage} from "../login/login";
import {SignUpPage} from "../signup/signup";
import {HomePage} from "../home/home";
import { Paytm } from '@ionic-paytm/paytm';

@Component({
    selector: 'page-apphome',
    templateUrl: 'apphome.html'
})
export class AppHomePage implements OnInit {

    constructor(public navCtrl: NavController ,public paytm:Paytm) {}

    ngOnInit(){
        window.plugins.paytm.startPayment("526", "25862", "abc@gmail.com", 
           "777777777", "25", successCallback, failureCallback);
        var userids=window.localStorage.getItem('userid');
        //alert(userids);
        if(userids!= null)
        {
            this.navCtrl.push(HomePage);
        }
    }
}

您可以简单地归档它。

Create CHECKSUMHASH using backend (.net, php, etc..)在 API 的帮助下，只需在表单中替换 checksumhash。或者您可以在从 APIform获取时在组件本身中创建。checksumhash

在paytm 文档的帮助下创建 CHECKSUMHASH 。第 2 步，然后返回 CHECKSUMHASH。Take all parameters from frontend.

例如：我只使用了一个按钮进行交易，现在不需要任何形式。在 checksumhash 之后，我将创建表单。

app.component.html ：

<button type="button" (click)="submitForm()">PAY NOW</button>

app.component.ts ：

constructor(private http: HttpClient) { }

// I have all below fields values
paytm = {
    MID: "xxxxx", // paytm provide
    WEBSITE: "WEBSTAGING", // paytm provide
    INDUSTRY_TYPE_ID: "Retail", // paytm provide
    CHANNEL_ID: "WEB", // paytm provide
    ORDER_ID: "xxxxx", // unique id
    CUST_ID: "xxxxx", // customer id
    MOBILE_NO: "xxxx", // customer mobile number
    EMAIL: "xxxx", // customer email
    TXN_AMOUNT: "10.00", // transaction amount
    CALLBACK_URL: "http://localhost:4200/paymentverity", // Call back URL that i want to redirect after payment fail or success
  };

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();
        };       
};

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();
// after click will fire you will redirect to paytm payment page.
// after complete or fail transaction you will redirect to your CALLBACK URL
};

PayTM 和 PayU 都还在旧的网络服务上，它们仍然不支持 REST，所以，您需要准备好网络 api 中的所有参数，然后将其作为名称值数组发送，然后将其绑定到角度页面，然后要么做自动发布或手动发布

<form ngNoForm  #myFormPost name="myFormPost" id="payForm" [action]="postURL" method="POST">
    <ng-container *ngFor="let input of apiResponse">
        <input *ngIf="!input.multiline" type="hidden" [name]="input.name" [value]="input.value" />
        <textarea *ngIf="input.multiline" [name]="input.name" class="textarea--hidden">{{input.value}}</textarea>
      </ng-container>
      <button (click)="onPost()">Post</button> 
</form>

{{input.value}} 发布 {{input.value}} 发布 
 Dictionary<string, string> dicPam = new Dictionary<string, string>
            {
                { "MID", parameters.MID },
                { "CHANNEL_ID", parameters.CHANNEL_ID },
                { "INDUSTRY_TYPE_ID", parameters.INDUSTRY_TYPE_ID},
                { "WEBSITE", parameters.WEBSITE},
                { "EMAIL", parameters.EMAIL},
                { "MOBILE_NO", "9999999999" },
                { "CUST_ID", parameters.CUST_ID },
                { "ORDER_ID", parameters.ORDER_ID },
                { "TXN_AMOUNT", parameters.TXN_AMOUNT},
                { "CALLBACK_URL", parameters.CALLBACK_URL} //This parameter is not mandatory. Use this to pass the callback url dynamically.
            };

        var payTMParams = _mapper.Map<PayTMParams>(parameters);
        payTMParams.CHECKSUMHASH= CheckSum.generateCheckSum(merchantKey, dicPam);

        var PayParams = new PaymentParams();
        PayParams.PostURL= _configuration.GetSection("PaymentConfig:PayTM:POSTURL").Value;
        foreach (var item in dicPam)
        {
            PayParams.PayParams.Add(new ValPair { Name = item.Key, Value = item.Value });
        }

        PayParams.PayParams.Add(new ValPair { Name = "CHECKSUMHASH", Value = payTMParams.CHECKSUMHASH });
        return PayParams;

关于paytm，他们不支持REST。所以最好遵循普通的表单提交机制。所以根据他们的文档，我们可以将所需的参数与CHECKSUMHASH一起作为普通的POST请求传递。对于表单中的那个

<form ngNoForm method="post"action="https://securegwstage.paytm.in/theia/processTransactio">

ngNoForm 将直接将所有数据发布到他们的网关。

当我从http://paywithpaytm.com/developer/discussion/topic/how-to-integrate-paytm-in-angularjs-web-app/获得一些信息时，很明显，paytm 不支持 angular js ，它们仅在集成和checksum generation逻辑方面为您提供帮助，而无需下载我们的SDK它是不可能的。

检查https://github.com/Paytm-Payments/Paytm_App_Checksum_Kit_PHP
