如何使用swift在ios设备上发送自动电子邮件？

Question

当用户在我的IOS应用程序上创建帐户时,我想要发送给他的自动"谢谢"电子邮件,我该怎么做？我看到一家名为mailgun.com的公司,但他们不支持swift.Parse支持这个吗？我该怎么办？

如果parse支持此功能,请提供有关如何进行此设置的链接.这是我将使用的代码.

self.loginComplete("example@example.com")
func loginComplete(Email:String) {

\\send automatic email to the user.



}

就像Duncan C已经提到的那样,你无法从你的iOS应用程序发送电子邮件.唯一可行的解​​决方案是使用提供API来发送电子邮件的服务器.

如果您想使用mailgun.com,我已经制作了示例代码:

let request: NSMutableURLRequest = NSMutableURLRequest(URL: NSURL(string: "https://api.mailgun.net/v3/{YOUR SANDBOX DOMAIN}/messages")!)
request.HTTPMethod = "POST"

// Basic Authentication
let username = "api"
let password = "{YOUR API-KEY}"
let loginString = NSString(format: "%@:%@", username, password)
let loginData: NSData = loginString.dataUsingEncoding(NSUTF8StringEncoding)!
let base64LoginString = loginData.base64EncodedStringWithOptions([])
request.setValue("Basic \(base64LoginString)", forHTTPHeaderField: "Authorization")

let bodyStr = "from=Mailgun Sandbox <{YOUR SANDBOX DOMAIN}>&to=Receiver name <{YOUR RECEIVER EMAIL}>&subject=Test&text=thank you!"

// appending the data       
request.HTTPBody = bodyStr.dataUsingEncoding(NSUTF8StringEncoding);

let task = NSURLSession.sharedSession().dataTaskWithRequest(request, completionHandler: { (data, response, error) -> Void in
    // ... do other stuff here
})

task.resume()

目标C.

NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:[NSURL URLWithString:@"https://api.mailgun.net/v3/{YOUR SANDBOX DOMAIN}/messages"]];
request.HTTPMethod = @"POST";

NSString *username = @"api";
NSString *password = @"{YOUR API-KEY}";
NSString *loginString = [NSString stringWithFormat:@"%@:%@", username, password];
NSData *loginData = [loginString dataUsingEncoding:NSUTF8StringEncoding];
NSString *base64LoginString = [loginData base64EncodedStringWithOptions:0];
NSString *requestValue = [NSString stringWithFormat:@"Basic %@", base64LoginString];
[request setValue:requestValue forKey:@"Authorization"];

NSString *bodyStr = @"from=Mailgun Sandbox <{YOUR SANDBOX DOMAIN}>&to=Receiver name <{YOUR RECEIVER EMAIL}>&subject=Test&text=thank you!";

// appending the data
request.HTTPBody = [bodyStr dataUsingEncoding:NSUTF8StringEncoding];

NSURLSessionDataTask *task = [[NSURLSession sharedSession] dataTaskWithRequest:request completionHandler:^(NSData * _Nullable data, NSURLResponse * _Nullable response, NSError * _Nullable error) {
    // ... do other stuff here
}];

[task resume];

注意

由于新的App Transport Security,您必须向Info.plist文件添加一个声明,该声明指定Mailgun API,因为它们在撰写本文时不支持最新的SSL技术.这是一个链接和一个示例配置:

• Apple Developer App Transport Security
