你好，我正在写一个nodejs方法，我想把一个ejs文件转换成一个pdf文件
router.get("/uknow", (req, res) => {
ejs.renderFile(path.join(__dirname, "../../views/resultat.ejs"), (err, data) => {
if (err) {
res.send(err);
} else {
pdf.create(data).toFile("report.pdf", function (err, data) {
if (err) {
res.send(err);
} else {
res.send("File created successfully");
}
});
}
});
})
这是我写的方法，我在post man中得到了这个回应
{
"path": "C:\\Users\\HP\\Desktop\\exemple CRUD\\blog_api\\views\\resultat.ejs"
}
我打印错误，这就是我得到的referenceerror:
C:\Users\HP\Desktop\exemple CRUD\blog_api\views\resultat.ejs:41

控制台里什么都没有，我需要一些帮助，谢谢你
首先呈现文件（与您的数据），然后将呈现的HTML传递给PDF'er
未经测试，请尝试以下操作:
router.get("/uknow", (req, res) => {
// your missing data, wheres it coming from?
// it should also look like:
// let data = { data: [{ imei: { name: '', ...}}, ...], ...}
// render the ejs file
ejs.renderFile(path.join(__dirname, '..', '..', 'views', 'resultat.ejs'), data, {}, function(err, str) {
if (err) return res.send(err);
// str now contains your rendered html
pdf.create(str).toFile("report.pdf", function(err, data) {
if (err) return res.send(err);
res.send("File created successfully");
});
});
});
