[英]Send Sendgrid Email Without Subject
是否可以通过Sendgrid发送没有主题的电子邮件? 我尝试将主题字段留空,但收到一条错误消息,内容为
TypeError: Cannot read property 'map' of undefined
这是我的代码...
var helper = require('sendgrid').mail;
var fromEmail = new helper.Email("myemail@email.com");
var toEmail = new helper.Email("sendEmail@email.com");
//I set the subject to null
var subject = null;
var content = new helper.Content('text/html', "my message");
var mail = new helper.Mail(fromEmail, subject, toEmail, content);
var sg = require('sendgrid')('-----------------');
var request = sg.emptyRequest({
method: 'POST',
path: '/v3/mail/send',
body: mail.toJSON()
});
sg.API(request, function (error, response) {
});
我尝试将主题设置为null
和"";
但均返回错误消息。
有任何想法吗?
您不能通过API发送带有空白subject
的电子邮件。 在此处查看文档: https : //sendgrid.com/docs/API_Reference/api_v3.html
如果向下滚动到subject参数,您会看到它说:
电子邮件的全局或“邮件级别”主题。 这可能会被个性化设置[x] .subject覆盖。 minLength 1
它还说这是必需的。 如果您查看可以覆盖电子邮件主要subject
的personalization
subject
参数,它将指向关于主题限制的SO答案: 什么是电子邮件主题长度限制?
因此,基本上,该库的编写方式是假定该地图上存在一个主题,并且会出错。
为了测试它,我做了如下的快速卷曲:
curl -X POST \
https://api.sendgrid.com/v3/mail/send \
-H 'authorization: Bearer MYAPIKEY' \
-H 'cache-control: no-cache' \
-H 'content-type: application/json' \
-d '{
"personalizations": [
{
"to": [
{
"email": "testemail@test.com"
}
],
}
],
"from": {
"email": "testemail@test.com"
},
"content": [
{
"type": "text/plain",
"value": "Hello, World!"
}
]
}
并得到此响应:
{
"errors": [
{
"message": "The subject is required. You can get around this requirement if you use a template with a subject defined or if every personalization has a subject defined.",
"field": "subject",
"help": "http://sendgrid.com/docs/API_Reference/Web_API_v3/Mail/errors.html#message.subject"
}
]
}
