ios - (有效负载不是有效的 JSON)尝试快速打印到空闲空间

Question

let str = "payload={'channel': '#bottest', 'username': 'garrettogrady', 'text': 'This post is coming from swift.'}"
    let strData = (str as NSString).dataUsingEncoding(NSUTF8StringEncoding)
    let cachePolicy = NSURLRequestCachePolicy.ReloadIgnoringLocalCacheData

    let url = NSURL(string: "web hook url (leaving it out for privacy reasons")

    var request = NSMutableURLRequest(URL: url!, cachePolicy: cachePolicy, timeoutInterval: 2.0)

    request.HTTPMethod = "POST"
    request.HTTPBody = strData
    println("printing to slack")
    var error : NSError? = nil
    if let data = NSURLConnection.sendSynchronousRequest(request, returningResponse: nil, error: &error) {
        let results = NSString(data:data, encoding:NSUTF8StringEncoding)
        println(results)
    }
    else
    {
        println("data invalid")
        println(error)
    }

所以当我运行这段代码时，我不会出错。但是当我打印结果时，它说“有效负载不是有效的 JSON”

Slack 期望在 JSON 上使用双引号。您得到的结果是 Slack 拒绝了您当前形成的 JSON。

这是我自己的代码，它可以让您合并各个字段的变量值，我认为这是您的下一步。

let channel = "#bottest"
let username = "garrettogrady"
let text = "This post is coming from swift."
let payload = "payload={\"channel\": \"\(channel)\", \"username\": \"\(username!)\", \"text\": \"\(text)\""}"

编辑:这个问题启发了我创建一个对象来实现 Slack webhook API。这是给任何感兴趣的人的:https://github.com/pfj3/SwiftSlackbots
