【问题描述】：

我想在 mailchimp API 的帮助下创建一个时事通讯。在下面你可以找到我为注册而编写的必要代码。当我填写表格并按提交时出现错误。
signup.html 文件包含一个简单的表单，其中包含 3 个输入（名字、姓氏和电子邮件）和一个提交按钮。这是我的 app.js 代码：

  

    const express = require(\"express\");
    const request = require(\"request\");
    const bodyParser = require(\"body-parser\");
    const app = express();
    const https = require(\"https\");

    app.use(bodyParser.urlencoded({ extended: true }));
    app.use(express.static(\"public\"));

    app.get(\"/\", function (req, res) {
      res.sendFile(__dirname + \"/signup.html\");
    });

    app.post(\"/\", function (req, res) {
      const fname = req.body.firstName;
      const sname = req.body.lastName;
      const e_mail = req.body.Email;
      const data = {
        members: [
          {
            email_address: e_mail,
            status: \"subscribed\",
            merge_fields: [
              {
                FNAME: fname,
                LNAME: sname,
              },
            ],
          },
        ],
      };

      var jsonData = JSON.stringify(data);
      const url = \"https://us10.api.mailchimp.com/3.0/lists/{list_id}\";
      const options = {
        method: \"POST\",

        auth: \"hamza:{API_id}\",
      };
      https.request(url, options, function (response) {
        const request = response.on(\"data\", function (data) {
          console.log(JSON.parse(data));
        });
        request.write(jsonData);
        request.end();
      });
    });

    app.listen(3000, function () {
      console.log(\"working successfully\");
    });

这是我得到的错误

          throw er; // Unhandled \'error\' event
          ^

【解决方案1】：

既然你写了这一行

app.use(express.static("public"));

你应该把你的res.sendFile写成

res.sendFile(signup.html);

你的const data 应该写成

const data = {
        members: [
            {
                email_address: email,
                status: "subscribed",
                merge_fields: {
                    FNAME: firstName,
                    LNAME: lastName
                }
            }
            
        ]
    }

const option 中不需要额外的逗号，就在 auth 之后：

你的https request 应该写成

 const request = https.request(url, options, function(response){
        response.on('data', function(data){
            console.log(JSON.parse(data))
        })
    })

我希望这有帮助

PS：还要确保你的input标签中的name来自signup.html中的form是正确编写的。
