使用Node.js的SendGrid模板中的变量替换不起作用
[英]Variable substitution in SendGrid templates with Nodejs does not work
问题描述
Following the USE CASE on SendGrids github does manage to send me the e-mail with the correct template, but the substitutions does apparently not work, and is left blank in the resulting e-mail. 
在SendGrids上使用USE案例之后，github确实设法向我发送了具有正确模板的电子邮件，但是替换显然不起作用，并且在生成的电子邮件中留为空白。 Server side: 服务器端：
const sgmailer = require("@sendgrid/mail");
sgmailer.setApiKey(process.env.SENDGRID_API_KEY);
sgmailer.setSubstitutionWrappers('{{', '}}');
const msg = {
to: '...',
from: 'sender@example.org',
subject: 'Hello world',
text: 'Hello plain world!',
html: '<p>Hello HTML world!</p>',
templateId: '...',
substitutions: {
name: 'Some One',
city: 'Denver',
},
};
sgmailer.send(msg)
HTML in template: 模板中的HTML：
<html> <head> <title></title> </head> <body> Hello {{name}}, <br /><br/> I'm glad you are trying out the template feature! <br /><br/> <%body%> <br /><br/> I hope you are having a great day in {{city}} :) <br /><br/> </body> </html>
Resulting email in my inbox: 结果在我的收件箱中的电子邮件：
Hello ,
I'm glad you are trying out the template feature!
I hope you are having a great day in :)
Here the variables are clearly missing. 这里显然没有变量。 How do I substitute variables correctly? 如何正确替换变量？

Since what I was using was dynamic templates from SendGrid, I cannot use the "substitutions" tag, but must instead use the "dynamic_template_data" tag, see this issue . 由于我使用的是来自SendGrid的动态模板，因此无法使用“ substitutions”标签，而必须使用“ dynamic_template_data”标签，请参见此问题 。 When changing the msg-object to 将msg-object更改为
const msg = {
to: '...',
from: 'sender@example.org',
subject: 'Hello world',
text: 'Hello plain world!',
html: '<p>Hello HTML world!</p>',
templateId: '...',
dynamic_template_data: {
name: 'Some One',
city: 'Denver',
},
};
it works. 有用。 This is not documented in the SendGrid-documentation as far as I can see. 据我所知，这未在SendGrid文档中进行记录。
