Swift使用MailGun发送电子邮件

Problem

我想使用MailGun服务从纯粹的Swift应用程序发送电子邮件 .

Research So Far

据我了解，there are two methods to send an email通过MailGun . 一种是通过电子邮件向MailGun发送电子邮件，MailGun将重定向它（请参阅通过SMTP发送） . 据我所知，这将无法正常工作，因为iOS无法以编程方式自动发送邮件，并且必须使用methods that require user intervention . 因此，我应该直接使用API . 据我了解，我需要打开一个URL来执行此操作，因此我应该使用某种形式的 NSURLSession ，根据this SO answer

Code

MailGun提供了Python的文档，如下所示：

def send_simple_message():
return requests.post(
    "https://api.mailgun.net/v3/sandbox(Personal info).mailgun.org/messages",
    auth=("api", "key-(Personal info)"),
    data={"from": "Excited User <(Personal info)>",
          "to": ["bar@example.com", "(Personal info)"],
          "subject": "Hello",
          "text": "Testing some Mailgun awesomness!"})

用（个人信息）代替密钥/信息/电子邮件 .

Question

我如何在Swift中做到这一点？

谢谢！

    在python中， auth 正在 Headers 中传递 .

    你必须做一个http post请求，传递 Headers 和正文 .

    这是一个有效的代码：

    func test() {
        let session = NSURLSession.sharedSession()
        let request = NSMutableURLRequest(URL: NSURL(string: "https://api.mailgun.net/v3/sandbox(Personal info).mailgun.org/messages")!)
        request.HTTPMethod = "POST"
        let data = "from: Excited User <(Personal info)>&to: [bar@example.com,(Personal info)]&subject:Hello&text:Testinggsome Mailgun awesomness!"
        request.HTTPBody = data.dataUsingEncoding(NSASCIIStringEncoding)
        request.setValue("key-(Personal info)", forHTTPHeaderField: "api")
        let task = session.dataTaskWithRequest(request, completionHandler: {(data, response, error) in

            if let error = error {
                print(error)
            }
            if let response = response {
                print("url = \(response.URL!)")
                print("response = \(response)")
                let httpResponse = response as! NSHTTPURLResponse
                print("response code = \(httpResponse.statusCode)")
            }


        })
        task.resume()
    }

    requests.post发送HTTP POST请求，将键/值对编码为 application/x-www-form-urlencoded . 你需要做同样的事情 .

    我花了好几个小时试图让选定的答案工作，但无济于事 .

    虽然我终于能够通过大型HTTP响应使其正常工作 . 我把完整的路径放到Keys.plist中，这样我就可以将我的代码上传到github，并将一些参数分解为变量，这样我就可以在以后的程序中设置它们 .

    // Email the FBO with desired information
// Parse our Keys.plist so we can use our path
var keys: NSDictionary?

if let path = NSBundle.mainBundle().pathForResource("Keys", ofType: "plist") {
    keys = NSDictionary(contentsOfFile: path)
}

if let dict = keys {
    // variablize our https path with API key, recipient and message text
    let mailgunAPIPath = dict["mailgunAPIPath"] as? String
    let emailRecipient = "bar@foo.com"
    let emailMessage = "Testing%20email%20sender%20variables"

    // Create a session and fill it with our request
    let session = NSURLSession.sharedSession()
    let request = NSMutableURLRequest(URL: NSURL(string: mailgunAPIPath! + "from=FBOGo%20Reservation%20%3Cscheduler@<my domain>.com%3E&to=reservations@<my domain>.com&to=\(emailRecipient)&subject=A%20New%20Reservation%21&text=\(emailMessage)")!)

    // POST and report back with any errors and response codes
    request.HTTPMethod = "POST"
    let task = session.dataTaskWithRequest(request, completionHandler: {(data, response, error) in
        if let error = error {
            print(error)
        }

        if let response = response {
            print("url = \(response.URL!)")
            print("response = \(response)")
            let httpResponse = response as! NSHTTPURLResponse
            print("response code = \(httpResponse.statusCode)")
        }
    })
    task.resume()
}

    Mailgun Path在Keys.plist中作为名为mailgunAPIPath的字符串，其值为：

    https://API:key-<my key>@api.mailgun.net/v3/<my domain>.com/messages?

    希望这为其他任何遇到MailGun问题并希望避免第三方解决方案的人提供解决方案！
