如何修复err:nodemailer附件发送后无法加载PDF文档? [英] how to fix err:Failed to load PDF document once sent by nodemailer attachments?
问题描述
我有一个应用程序,可以使用Nodemailer发送带有附件的电子邮件.首先,我使用multer将附件保存在服务器上(运行良好),因此我可以将文件的路径传递给nodemailer路由中的附件.电子邮件和附件已成功发送,但附件无法打开/阅读!
I got an app which sending emails with attachments using Nodemailer. First I'm using multer to save the attachment on the server (working well) so I can pass the path of the file to attachments in the nodemailer route. The email and attachment is successfully sent but the attachment failed to be opened/read!
这是nodemailer路由:
Here is the nodemailer route:
app.post("/send", function(req,res){
var transporter = nodemailer.createTransport({
service: 'gmail',
auth: {
user: 'my gmail',
pass: 'my pass'
}
});
var quotename = req.params.id;
console.log(quotename);
var storage = multer.diskStorage({
destination: function (req,file, callback){
callback(null, './uploads');
},
filename: function (req, file, callback){
callback(null, "Q" + quotename + ".pdf");
}
});
var upload = multer ({storage : storage}).single("myFile");
upload(req, res, function(err){
if(err){
console.log(err);
} else {
const mailOptions = {
from: req.body.fr, // sender address
to: req.body.to, // list of receivers
bcc: req.body.fr,
subject: req.body.subject, // Subject line
html: '<h4>Dear ' + req.body.contname+ '</h4>' + '<p>'+
req.body.message + '</p>' + '<p>Kind Regards</p>' +
req.body.user,// html body
attachments: [
{ // filename and content type is derived from path
filePath: '/constimator/uploads/Q' + quotename + '.pdf',
},
],
};
transporter.sendMail(mailOptions, function (err, info) {
if(err){
return console.log(err);
}else{
console.log(req.body.myFile)
res.redirect("/submitted"); }
});
});
});
我不知道这是由于文件路径/路径问题还是其他原因.我也尝试过path(而不是filePath),但是有同样的问题
I don't know if it's because of filepath/path issue or something else. I tried path(instead of filePath) as well but the same problem
推荐答案
经过大量的反复试验,谷歌搜索和思考,我自己解决了问题.为了将来的参考以及遇到同样问题的人们,我将我的回答发布如下:
I solve the problem myself after lots of trial and error, googling, thinking. For the future refrence and for the people with the same problem, I post my answer as follows:
我已对此附件进行了更改,并且效果很好:
I have changed the attachments to this and it worked perfectly:
{ // filename and content type is derived from path
filename: "Q" + quotename + ".pdf",
contentType: 'application/pdf',
path: '/constimator/uploads/Q' + quotename + '.pdf',
},
],
这很简单,只需添加文件名,内容类型并将文件路径更改为路径,即可解决问题
It was very simple, by adding filename, content type and change filepath to path, probelm solved
