Mailgun HTTP错误代码400错误请求

Question

Mailgun给了我一个HTTP代码400，根据他们的文档，这意味着

错误的请求-通常缺少必需的参数https://documentation.mailgun.com/en/latest/api-intro.html#errors

我在firebase云功能中具有邮件发送功能，这是云功能

 app.post('/sendMail', (req, res) => { const data = { from: 'Excited User <me@samples.mailgun.org>', to: 'email, apikey', subject: 'Hello', text: 'Testing some Mailgun awesomness!' }; mailgun.messages().send(data, function (error, body) { if(error){ console.log(error); res.send(error) } console.log(body); res.send('sent email!') }); }); exports.app = functions.https.onRequest(app); 

我在我的应用程序内部将此函数称为应用程序内部的代码：

 sendEmail(){ let url = `URL to my cloud function`; let params: URLSearchParams = new URLSearchParams(); let data = { from: 'Excited User <me@samples.mailgun.org>', to: 'myEmail , apiKey', subject: 'Hello', text: 'Testing some Mailgun awesomness!' }; return this.http.post(url,data) .toPromise() .then(res=>{ console.log(`Res:`,res); }) .catch(err => { console.log('Error',err); }) } 

我遵循了firebase API https://documentation.mailgun.com/en/latest/quickstart-sending.html#send-via-api，我不知道缺少什么参数，因为我只是复制并粘贴了示例代码

我改变了这个

 const data = { from: 'Excited User <me@samples.mailgun.org>', to: 'email, apikey', subject: 'Hello', text: 'Testing some Mailgun awesomness!' }; 

至：

 const data = { from: 'me@samples.mailgun.org', to: 'email', subject: 'Hello', text: 'Testing some Mailgun awesomness!' };
