Angular Ngx Stripe 错误：“对象”类型上不存在属性“id”

Question

我将Ngx Stripe示例剪切并粘贴到我的 Angular 项目中。 我正在使用 Angular 13。我收到此错误：

Error: src/app/checkout/checkout.component.ts:22:77 - error TS2339: Property 'id' does not exist on type 'Object'.

22           return this.stripeService.redirectToCheckout({ sessionId: session.id })

这是strict模式错误吗？ 我是否需要在 function 上输入返回类型:any ？ 我试过session: any但没有编译。 .pipe让我感到困惑，返回类型是 go。

还是有其他原因导致错误？

这是我的checkout.component.ts ：

import { Component } from '@angular/core';
import { HttpClient } from '@angular/common/http';
import { switchMap } from 'rxjs/operators';

import { StripeService } from 'ngx-stripe';

@Component({
  selector: 'app-checkout',
  templateUrl: './checkout.component.html'
})
export class CheckoutComponent {
  constructor(
    private http: HttpClient,
    private stripeService: StripeService
  ) {}

  checkout() {
    // Check the server.js tab to see an example implementation
    this.http.post('/create-checkout-session', {})
      .pipe(
        switchMap(session => {
          return this.stripeService.redirectToCheckout({ sessionId: session.id })
        })
      )
      .subscribe(result => {
        // If `redirectToCheckout` fails due to a browser or network
        // error, you should display the localized error message to your
        // customer using `error.message`.
        if (result.error) {
          alert(result.error.message);
        }
      });
  }
}

这是我的app.module.ts ：

// Angular
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { FormsModule } from '@angular/forms';
import { BrowserAnimationsModule } from '@angular/platform-browser/animations';
import { AppRoutingModule } from './app-routing.module';
import { AppComponent } from './app.component';

// Material
import { MatToolbarModule } from '@angular/material/toolbar';
import { MatInputModule } from '@angular/material/input';
import { MatFormFieldModule } from '@angular/material/form-field';
import { MatButtonModule } from '@angular/material/button';
import { MatCardModule } from '@angular/material/card';
import { MatTabsModule } from '@angular/material/tabs';

// Made by me
import { HomeComponent } from './home/home.component';
import { FunctionsService } from './home/functions.service';
import { AboutMaggieComponent } from './about-maggie/about-maggie.component';
import { AboutKabbalahComponent } from './about-kabbalah/about-kabbalah.component';
import { DonateComponent } from './donate/donate.component';
import { ContactComponent } from './contact/contact.component';
import { CheckoutComponent } from './checkout/checkout.component';

// 3rd party
import { NgxStripeModule } from 'ngx-stripe';

@NgModule({
  declarations: [
    AppComponent,
    AboutMaggieComponent,
    HomeComponent,
    AboutKabbalahComponent,
    DonateComponent,
    ContactComponent,
    CheckoutComponent,
  ],
  imports: [
    BrowserModule,
    FormsModule,
    AppRoutingModule,
    BrowserAnimationsModule,
    MatToolbarModule,
    MatInputModule,
    MatFormFieldModule,
    MatButtonModule,
    MatCardModule,
    MatTabsModule,
    NgxStripeModule.forRoot('pk_test_51HUwT...'),
  ],
  providers: [FunctionsService],
  bootstrap: [AppComponent]
})
export class AppModule { }

我用npm安装了ngx-stripe ，我在项目的节点模块中看到了它。 我还没有设置后端服务器代码。

发生该错误是因为 TypeScript 严格检查 Object 类型（假设session将是）并且找不到“id”属性。

但是，我们可以假设session在发送响应时将具有id属性，因为我们遵循官方 ngx-stripe 文档。

要消除此错误，您可以将any类型分配给session ：

// Check the server.js tab to see an example implementation
this.http.post('/create-checkout-session', {})
  .pipe(
    switchMap((session: any) => {
      return this.stripeService.redirectToCheckout({ sessionId: session.id })
    })
  )
  .subscribe(result => {
    // If `redirectToCheckout` fails due to a browser or network
    // error, you should display the localized error message to your
    // customer using `error.message`.
    if (result.error) {
      alert(result.error.message);
    }
  });
