Question

每次尝试发送电子邮件时，都会收到与跨域相关的BadRequest。我试图搜索问题，但似乎是因为我是从浏览器（本地主机）调用，因此无法正常工作。基本上，我正在对我的Aspnet mvc进行Ajax调用，他们调用了WebApi项目

public async Task<Response> SendEmail(string email, string link, string companyName)
    {
        var apiKey = Environment.GetEnvironmentVariable("SMTP");
        var client = new SendGridClient(apiKey);

        var from = new EmailAddress("d.com", "d");
        var subject = "Sending with SendGrid is Fun";
        var to = new EmailAddress(email, "Caro");
        var plainTextContent = "and easy to do anywhere, even with C#";
        var htmlContent = "<strong>Aqui está seu contrato </strong>";
        var msg = MailHelper.CreateSingleEmail(from, to, subject, plainTextContent, htmlContent);
        return await client.SendEmailAsync(msg);

    }

这是响应：

{服务器：nginx 日期：2019年12月10日，星期二14:17:40 GMT 连接：保持活动状态访问控制允许来源：https://sendgrid.api-docs.io 访问控制允许方法：POST 访问控制允许标头：授权，内容类型，代表，x-sg-elas-acl 存取控制的最大年龄：600 X-否-CORS原因：https://sendgrid.com/docs/Classroom/Basics/API/cors.html }

不知道该怎么办。我应该在HttpClient类的标题中添加一些内容吗？

 private async Task<string> SendMail(string to, string text)
        {
            try
            {
                var msg = new SendGridMessage();
                msg.SetFrom(new EmailAddress("youremail@email.com", "Your Name"));
                msg.AddTo(to);
                msg.SetSubject("Your subject here");
                msg.AddContent(MimeType.Text, text);
                var client = new SendGridClient("???"); // Your sendgrid client private id here
                var response = await client.SendEmailAsync(msg);
                if (response.StatusCode == System.Net.HttpStatusCode.Accepted)
                    return "ok";
                else return "failed"; // not happening ))
            }
            catch (Exception e)
            {
                return e.Message;
            }
        }

无法使用SendGrid WebApi lib发送电子邮件
