未找到404 404

Question

如果我使用POST请求，它可以运行，如下所示：

http://localhost:5001/orders/1

但是，试图使用axios在React中访问端点会导致以下错误，如控制台所示：

xhr.js:155 POST http://localhost/orders/1 404 (Not Found)

这是我用来请求的表单：

<form onSubmit={ (event) => this.handleSubmitOrder(event) }>
          <div className="field">
             <input
                name="client"
                className="input is-dark is-large"
                type="text"
                placeholder="Client name"
                required
                //value={this.state.formClient.client}
                onChange={this.handleOrderFormChange}
              /> 
          </div>
            <div className="field">
              <input
                name="email"
                className="input is-dark is-large"
                type="text"
                placeholder="Client email"
                required
                //value={this.state.formClient.email}
                onChange={this.handleOrderFormChange}
              />
            </div>
          <div className="field">
            <input
              name="phone"
              className="input is-dark is-large"
              type="text"
              placeholder="Client phone"
              required
              //value={this.state.formClient.phone}
              onChange={this.handleOrderFormChange}
            />
          </div>
          <div className="field">
            <input
              name="select"
              className="input is-dark is-large"
              type="text"
              placeholder="Coffee ordered by client"
              required
              //value={this.state.formClient.select}
              onChange={this.handleOrderFormChange}
            />
          </div>
          <input
            type="submit"
            className="button is-dark is-large is-fullwidth"
            value="Submit"
            //disabled={!this.state.valid}  
          />
          </form>

这是函数onSubmit()

handleSubmitOrder(event) {
    const {userId} = this.props
    const data = {
      client: this.state.formClient.client,
      phone: this.state.formClient.phone,
      email: this.state.formClient.email,
      select: this.state.formClient.select,
    };
    var headers = {
        'Content-Type': 'application/json',
        //'Access-Control-Allow-Origin': true,
        Authorization: `Bearer ${window.localStorage.authToken}`
      }
    const url = `${process.env.REACT_APP_WEB_SERVICE_URL}/orders/${userId}`;
    axios.post(url, data, {headers: headers})
      .then((res) => {
        console.log(data);
      })
      .catch((err) => {
      });
  };

后退

@orders_bp.route('/orders/<user_id>', methods=['GET','POST'])
def orders(user_id):

Nginx/Docker我的应用程序配置了nginx，在dev.conf中有：

location /orders {
    proxy_pass        http://web:5000;
    proxy_redirect    default;
    proxy_set_header  Upgrade $http_upgrade;
    proxy_set_header  Connection "upgrade";
    proxy_set_header  Host $host;
    proxy_set_header  X-Real-IP $remote_addr;
    proxy_set_header  X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header  X-Forwarded-Host $server_name;
  }

在docker-compose配置中：

web:
    build:
      context: ./services/web
      dockerfile: Dockerfile-dev
    volumes:
      - './services/web:/usr/src/app'

    ports:
      - 5001:5000

在上述配置中，对所有其他端点的所有其他请求都能顺利工作，但这次除外。我遗漏了什么？

Answer 1

如果我没有弄错你是错误消息显示的第一行

xhr.js:155 POST http://localhost/orders/1 404 (未找到)

URL缺少端口5001，所以我猜.env文件中的process.env.REACT_APP_WEB_SERVICE_URL值也缺少端口吗？

Answer 2

问题是nginx配置。

Location /orders已经添加到nginx.dev文件中，但是更改应该再次传播构建，而不仅仅是保存它。

在我做完之后：

docker-compose -f docker-compose-dev.yml up -d --build

请求开始正常工作。
