解析服务器中没有这样的文件或目录 - 云代码

Question

我正在使用 Parse 服务器，并且正在尝试发送带有 Html 文件的电子邮件。 问题我不太确定如何从云代码访问公共文件夹。

这是错误：

ENOENT：没有那个文件或目录，打开'./public/invoice.html'

目录：

 │ ├── cloud │ │ ├── functions.js │ │ ├── main.js │ ├── public │ │ ├── invoice.html

fs.readFileSync("../public/invoice.html", "utf8"

这是我的代码：

  var fs = require('fs');

  Parse.Cloud.define("mailSend", function(request, response) {
    const apiKey = '4441*****************a47f';
    const mailgun = require("mailgun-js");
    const DOMAIN = 'user.mailgun.org';
    const mg = mailgun({apiKey: apiKey, domain: DOMAIN});
    const data = {
      from: 'email <email@example.com>',
      to: 'email@example.com',
      subject: 'Invoice',
      html:  fs.readFileSync("../public/invoice.html", "utf8") ||  null
    };
    mg.messages().send(data, function (error, body) {
      console.log(body);
    });
});

Answer 1

尝试这个：

var path = require('path');
var fs = require('fs');

  Parse.Cloud.define("mailSend", function(request, response) {
    const apiKey = '4441*****************a47f';
    const mailgun = require("mailgun-js");
    const DOMAIN = 'user.mailgun.org';
    const mg = mailgun({apiKey: apiKey, domain: DOMAIN});
    const data = {
      from: 'email <email@example.com>',
      to: 'email@example.com',
      subject: 'Invoice',
      html:  fs.readFileSync(path.join(__dirname, "../public/invoice.html"), "utf8") ||  null
    };
    mg.messages().send(data, function (error, body) {
      console.log(body);
    });
});

看起来很像。 检查并尝试，错误：ENOENT：没有这样的文件或目录，取消链接

Answer 3

谢谢大家的回答，这段代码对我来说很好用。 我使用 ejs 而不是 HTML。 你可以使用 HTML 但你必须添加

var fs = require('fs'); 代替 const ejs = require('ejs');

var path = require('path');
const ejs = require('ejs');
const mailgun = require("mailgun-js");
const apiKey = '444**********00a47f';
const DOMAIN = 'user.mailgun.org';
const mg = mailgun({apiKey: apiKey, domain: DOMAIN});

Parse.Cloud.define("SendEmail", function(request, response) {
        var orderId = request.params.orderId;
        var items = request.params.items;
        var details = request.params.details;
        var user = request.params.user;
        var subject = "Thank You for Your Order #" + orderId;
        var orderData = {
          user: user,
          items: items,
          details: details
        }

        ejs.renderFile(path.join(__dirname, './public/invoice.ejs'), orderData, (err, htmlString) => {
          if (err) console.error(err);

          let data = {
            from: 'app neme <email@gmail.com >',
            to: 'email@gmail.com',
            subject: subject,
            html: htmlString
          };

          mg.messages().send(data, function (error, body) {
            console.log(body);
            console.log(prods);
            response.success("success send");
          });
        });

    });
