Question

我正在尝试使用Google Cloud Function中的SendGrid发送电子邮件。我在Firebase环境变量中有密钥，因此存在。

const sgMail = require('@sendgrid/mail');
sgMail.setApiKey(SENDGRID_API_KEY);

这是我的GCF .ts代码：

代码

const msg = {
    to: to,
    from: from,
    subject: 'Email Subject',
    content: [{
        type: "text/html",
        value: body
    }]
};

await sgMail.send(msg)
    .then(r => {
        console.log(r);
    });

当我触发该功能并检查我的日志时，这是我得到的错误：

错误

        'x-no-cors-reason': 'https://sendgrid.com/docs/Classroom/Basics/API/cors.html' },
    body: { errors: [Object] } } }

有人对此错误有任何了解吗？它提到了CORS，但这没有任何意义，因为它是云功能，而不是浏览器。 SendGrid API并不是很好，它主要遍历字段名称并且没有提供示例。感谢您提供的任何帮助！

EDIT

只是为了更新问题，我在前端响应中向自己发送了一个错误，发现与GCF日志中的console.log(error)不同：

"Email failed: Bad Request (400)
The from object must be provided for every email send. 
It is an object that requires the email parameter, 
but may also contain a name 
parameter.  e.g. {"email" : "example@example.com"}  or 
{"email" : "example@example.com", "name" : "Example Recipient"}.
    from.email
    http://sendgrid.com/docs/API_Reference/Web_API_v3/Mail/errors.html#message.from"

编辑2：解决方案

我的电子邮件来源来自Firestore中的一个文档，并且我试图获取一个不存在的字段，因为我查询的文档错误，因此from是undefined。更正了该错误，并按照下面的建议/答案删除了msg对象中的“内容”，并且一切正常。

根据documentation ... msg具有错误的元素：

const sgMail = require('@sendgrid/mail');
sgMail.setApiKey(process.env.SENDGRID_API_KEY);

const msg = {
    to: 'test@example.com',
    from: 'test@example.com',
    subject: 'Sending with SendGrid is Fun',
    text: 'and easy to do anywhere, even with Node.js',
    html: '<strong>and easy to do anywhere, even with Node.js</strong>',
};

sgMail.send(msg)
.then(() => {
    /* assume success */
})
.catch(error => {

    /* log friendly error */
    console.error(error.toString());

    /* extract error message */
    const {message, code, response} = error;

    /* extract response message */
    const {headers, body} = response;
});
