如何使用Gmail api发送电子邮件

问题描述

没有明确的文档，如何做到这一点，我已经尝试使用，但有很多事情在空中。

The Gmail Api has no clear documentation on how to do this, I have been trying with this but there are many things that are in the air.

我已经寻求外部来源。 和源2 。第一个似乎使用api的潜力，使用函数 queryForUsersMessagesSendWithUploadParameters 。

I have sought external sources such. Source 1 and Source 2. The first seems to use the potential of the api, using the function queryForUsersMessagesSendWithUploadParameters.

虽然第二个是关于再多一点。虽然Objective-C中的这个问题不是一个问题，但GTMMIMEDocument对象不知道在哪里或者是获取或者是一个库。

While the second is about a little more. Although this in Objective-C is not a problem, except for the GTMMIMEDocument object, which do not know where or if it is obtained or a library.

我的问题是有人有点清洁和/或代码更容易理解，或更好的指导发送电子邮件

My question is if someone has a somewhat cleaner and / or code easier to understand, or a better guide in which to send an email

我发现解决方案

class func sendEmail() {

        var gtlMessage = GTLGmailMessage()
        gtlMessage.raw = self.generateRawString()

        let appd = UIApplication.sharedApplication().delegate as! AppDelegate
        let query = GTLQueryGmail.queryForUsersMessagesSendWithUploadParameters(nil)
        query.message = gtlMessage

        appd.service.executeQuery(query, completionHandler: { (ticket, response, error) -> Void in
            println("ticket \(ticket)")
            println("response \(response)")
            println("error \(error)")
        })
    }

    class func generateRawString() -> String {

        var dateFormatter:NSDateFormatter = NSDateFormatter()
        dateFormatter.dateFormat = "EEE, dd MMM yyyy HH:mm:ss Z"; //RFC2822-Format
        var todayString:String = dateFormatter.stringFromDate(NSDate())

        var rawMessage = "" +
            "Date: \(todayString)\r\n" +
            "From: <mail>\r\n" +
            "To: username <mail>\r\n" +
            "Subject: Test send email\r\n\r\n" +
            "Test body"

        println("message \(rawMessage)")

        return GTLEncodeWebSafeBase64(rawMessage.dataUsingEncoding(NSUTF8StringEncoding))
    }
