【问题描述】:
我正在做一个项目,我需要在 Angular 中将条带键作为 JSON 传递。
我在 Config vars 中添加了 Heroku 的密钥,并尝试使用 Heroku 教程中所述的 process.env.STRIPE_KEY 方法通过 Node.js 后端将该值传递给 Angular。我完全迷失了,不确定我是否以正确的方式进行。
这是我的节点服务器文件。
//server.js
const express = require('express');
const app = express();
const bodyParser = require("body-parser");
const router = express.Router();
app.use(express.static(__dirname + '/dist'));
router.use(bodyParser.json());
router.use(bodyParser.urlencoded({extended: true}));
app.listen(3000, function(){});
router.all('*',function(req,res,next) {
res.header("Access-Control-Allow-Origin", "*");
res.header("Access-Control-Allow-Headers", "Cache-Control, Pragma, Origin, Authorization, Content-Type, X-Requested-With");
res.header("Access-Control-Allow-Methods", "GET, PUT, POST, OPTIONS");
next();
});
router.post('/stripetestkey', function(req, res) {
res.json({
'STRIPE_TEST_API_KEY': process.env.STRIPE_KEY
});
});
module.exports = router;
这是服务提供者(在应用程序模块中并正确注入)从服务器获取密钥
//service.ts
import {Injectable} from "@angular/core";
import {Http, Headers} from "@angular/http";
import 'rxjs/add/operator/map';
import {Observable} from "rxjs";
@Injectable()
export class KeyService {
constructor(private http: Http) {}
private getError(error: Response): Observable<any>{
console.log(error);
return Observable.throw(error.json() || 'Server Issue');
}
getKey(): Observable<any> {
let headers = new Headers();
headers.append('Content-type', 'application/json');
return this.http.get('http://localhost:3000/stripetestkey',{ headers: headers })
.map(res => res.json())
.catch(this.getError);
}
}
这是我用正确的密钥打开 Stripe 结帐的代码
openCheckout() {
this.keyService.getKey().subscribe(data => this.stripeTestKey = data.STRIPE_TEST_API_KEY);
let handler = (<any>window).StripeCheckout.configure({
key: this.stripeTestKey,
locale: 'auto',
token: function (token: any) {
}
});
handler.open({
name: 'XXXXXX',
description: 'Donation',
amount: (this.donation * 100)
});
}
我一直在返回 HTML 而不是 JSON,我只是不确定我是否正确地处理了这个问题。我也尝试过传递 JSON 而不是 process.env.STRIPE_KEY。谁能让我知道我需要做什么才能通过 node.js 将 heroku config var 传递给我的 Angular 应用程序?
谢谢!
附:这是我收到的错误..
Failed to load resource: the server responded with a status of 404 (Not Found)
main.bundle.js:32 Response
vendor.bundle.js:1443 ERROR SyntaxError: Unexpected token < in JSON at position 0
at JSON.parse (<anonymous>)
at Response.Body.json
更新** 我在 server.js 中将 res.send 更改为 res.json,这是我得到的更新错误。
keys.service.ts:11 Response {_body: "<!DOCTYPE html>↵<html lang="en">↵<head>↵<meta char…body>↵<pre>Cannot GET /stripetestkey</pre>↵</body>↵</html>↵", status: 404, ok: false, statusText: "Not Found", headers: Headers…}
core.es5.js:1084 ERROR SyntaxError: Unexpected token < in JSON at position 0

更新 #2 ******* 我在 server.js 中将 router.post 更改为 router.get。我仍然收到上述相同的错误。我尝试将密钥直接作为对象传递
router.get('/stripetestkey', function(req, res) {
res.json({
'STRIPE_TEST_API_KEY': 'pk_test_XXXXXXXXXXXXXXXXXX'
});
});
Stripe 为我返回了这个错误。
StripeCheckout.configure: Type mismatch for option 'key':
Looking for type 'string', but instead we found 'object'.
You can learn about the available configuration options in the Checkout docs:
现在查看文档。
**** 仍然在这里挣扎
****更新(这么多) 将 http://localhost:3000/stripetestkey 更改为 https://localhost:3000/keys(还将服务器端更改为 /keys 以进行正确的路由(更易于遵循)。
