我正在构建 React/Node/Stripe 应用程序,基本设置工作正常,但是当我想扩展我的应用程序以从输入表单中收集电子邮件地址并将其以正文发送到节点后端以使用它来创建客户或发送电子邮件时。我在 console.log 中看到 req.body 中存在电子邮件,但我可以获取该字段。

收集电子邮件

 import React, { Component } from "react";
import { CardElement, injectStripe } from "react-stripe-elements";
import styled from "styled-components";






    class CheckoutForm extends Component {
      constructor(props) {
        super(props);
        this.state = {
          complete: false,
          name: "",
          email: ""
        };
      }
      handleChange = input => e => {
        this.setState({
          [input]: e.target.value
        });
        console.log(this.state.email);
      };
   submit = async () => {
    let { token } = await this.props.stripe.createToken({
      name: this.state.name,
      email: this.state.email
    });
    console.log(token);
    const email = this.state.email;
    const data = {
      token: token.id,
      email
    };
    let response = await fetch("/charge", {
      method: "POST",
      headers: {
        "Content-Type": "text/plain"
      },
      body: JSON.stringify(data)
    });
    console.log(response);
    if (response.ok)
      this.setState({
        complete: true
      });
  };;

      render() {
        if (this.state.complete) return <h1> Purchase Complete </h1>;
        return (
          <CheckOut>
            <CheckOutForm>
              <CheckOutFieldSet>
                <InputRow>
                  <Label htmlFor=""> Name </Label>
                  <Input
                    type="text"
                    placeholder="Jane Doe"
                    onChange={this.handleChange("name")}
                  />
                </InputRow>
                <InputRow>
                  <Label htmlFor=""> Email </Label>
                  <Input
                    type="email"
                    placeholder="jane@doe.com"
                    onChange={this.handleChange("email")}
                  />
                </InputRow>
                <InputRow last>
                  <Label htmlFor=""> Phone </Label>
                  <Input type="phone" placeholder="+48 999 000 999" />
                </InputRow>
              </CheckOutFieldSet>
              <CheckOutFieldSet>
                <CardElement />
              </CheckOutFieldSet>
            </CheckOutForm>
            <ButtonCheckOut onClick={this.submit}> Send </ButtonCheckOut>
          </CheckOut>
        );
      }
    }

    export default injectStripe(CheckoutForm);

存在响应电子邮件,但名称card对象中

card: {id: "card_1", object: "card", 
address_city: null, 
address_country: null, 
address_line1: null, …}
created: 1546375333
email: "emial"
id: "tok_1Dnu4wj"
livemode: false
object: "token"
type: "card"
used: false
__proto__: Objec

姓名

card:{
    last4: "4242"
    metadata: {}
    name: "Name"
}

后端

app.post("/charge", (req, res) => {
console.log(req.body)
//{"token":"tok_1DnuwhFw7kwjoel1NsD2Qd1r","email":"lll"}
stripe.charges.create({
    amount: 4000,
    currency: "usd",
    description: req.body.email,
    source: req.body.token
}).then(
    status => {
        res.json({
            status
        })
        // isValid = status.ok

    }
).catch(err => res.send(err))

let mail = req.body.email
console.log(mail)
//undefined

我知道这console.log(req.body)会给我令牌 ID,但是如何发送更多的东西,比如电子邮件地址?多一个?我刚刚收集的那个名字怎么可能createToken?我包含在令牌中吗?

您可以在正文中发送一个对象,只需使用body: JSON.stringify(data). 数据可以包含任何可序列化的内容。

另外,请确保您'Content-Type': 'application/json'的请求标头中有

正如@Dez 所指出的,确保您的服务器能够解析带有 JSON 有效负载的传入请求。express您可以使用body -parser中间件。
