【问题描述】:
我正在尝试使用 Angular 4、nodejs、mailgun-js 和 mailgun 对注册流程实施简单的电子邮件确认。问题是mailgun发送:
mailgun.messages().send(data, function(error, body) {
console.log(body);
});
正在超时,前端出现以下错误:
POST http://localhost:3000/users/sendMail net::ERR_EMPTY_RESPONSE
core.js:1448 ERROR
HttpErrorResponse {headers: HttpHeaders, status: 0, statusText: "Unknown Error", url: null, ok: false, …}
error
:
ProgressEvent {isTrusted: true, lengthComputable: false, loaded: 0, total: 0, type: "error", …}
headers
:
HttpHeaders {normalizedNames: Map(0), lazyUpdate: null, headers: Map(0)}
message
:
"Http failure response for (unknown url): 0 Unknown Error"
name
:
"HttpErrorResponse"
ok
:
false
status
:
0
statusText
:
"Unknown Error"
url
:
null
__proto__
:
HttpResponseBase
后端显示现在出错,但返回值(正文)未定义且未发送电子邮件。这是我完整的后端 sendMail 模块:
const api_key = '<key-f40360259dea7c667ca06d4aee956421>';
const DOMAIN = '<sandbox836cdf3cfe9c467b916fe5bb0d73e7e7.mailgun.org>';
const mailgun = require('mailgun-js')({ apiKey: api_key, domain: DOMAIN });
// ---------------- sendMail variables -----
router.post('/sendMail', (req, res, next) => {
console.log("Email message data: " + JSON.stringify(req.body));
const data = {
from: 'xxxxdev@gmail.com',
to: [req.body.email, 'xxxxxxx@gmail.com'],
name: req.body.firstName,
code: req.body.workshopCode,
subject: req.body.workshopTitle,
text: req.body.messageBody
};
mailgun.messages().send(data, function(error, body) {
console.log(body);
});
});
From 和 To 电子邮件都是有效的电子邮件地址,console.log 中显示的 req.body 是从前端传递的正确数据。
这是前端发送邮件模块:
sendEmailConfirmation(message) {
const headers = new HttpHeaders();
headers.append('Content-Type', 'application/x-www-form-urlencoded');
this.http.post('http://localhost:3000/users/sendMail', message).subscribe((data) => {
console.log('Mail return data: ' + data); >>>THIS LINE IS NEVER EXECUTED<<<<<<
},
);
}
我在这里错过了什么??.....
我注意到没有 res.send,所以我添加了以下内容:
if (error) throw error;
else {
res.send('Email sent');
}
现在我在后端收到一个禁止错误:
(node:10780) UnhandledPromiseRejectionWarning: Error: Forbidden
at IncomingMessage.res.on (C:\connect2Server\node_modules\mailgun-js\lib\request.js:301:17)

【问题讨论】:
-
您是否尝试在 mailgun API 调用的回调中记录错误?您收到
ERR_EMPTY_RESPONSE的原因是因为您在发送邮件后从未结束请求,例如res.sendStatus(200)表示成功或res.sendStatus(500)表示错误。 -
@Svenskunganka 我确实注意到了这一点并以(参见编辑)res.send('......')结束。我得到以下信息:...(节点:10780)UnhandledPromiseRejectionWarning:错误:禁止
