我遇到了一个问题，我的服务器期望来自应用程序端的字典数组。请建议我在这里出错的地方，下面的代码

    {
 let param : [String : AnyObject]  =
            ["trf_id"  :  Constant.constantVariables.trfID,
             "mode"              : Constant.modeValues.createMode,
             "to_city"           : Constant.constantVariables.to_city,
             "from_city"         : Constant.constantVariables.from_city,
             "description"       : Constant.constantVariables.descrption,
             "request_type"      : Constant.constantVariables.request_type,
             "to_date"           : Constant.constantVariables.to_date!,
             "from_date"         : Constant.constantVariables.from_date!,
             "travel_configs"    :  ["Config_id" : "9","values" : "train",
                                      "Config_id" : "10","values" : "bus"]]
        print(param)
}
  • travel_configs 是字典数组

由于服务器异常，我必须这样发送

trf_id:37
mode:1
request_type:0
from_city:sdfsd
to_city:qws
from_date:2016-08-17
to_date:2016-08-26
description:sdfsdf
travel_configs:[
{"config_id":"11","values":"1"}
,{"config_id":"2","values":"Flight"}]

经过3天的挣扎，我终于得到了答案

只需将您的字典数组发送到此类 func JSONStringify(value: AnyObject,prettyPrinted:Bool = false) -> String{

    let options = prettyPrinted ? NSJSONWritingOptions.PrettyPrinted : NSJSONWritingOptions(rawValue: 0)


    if NSJSONSerialization.isValidJSONObject(value) {

        do{
            let data = try NSJSONSerialization.dataWithJSONObject(value, options: options)
            if let string = NSString(data: data, encoding: NSUTF8StringEncoding) {
                return string as String
            }
        }catch {

            print("error")
            //Access error here
        }

    }
    return ""

}

希望这对其他人有帮助谢谢..

首先，它可能来自“config_id”中的大写“C”而不是“c”？

其次，您实际上缺少 []，您的代码应如下所示：

let param : [String : AnyObject]  =
            ["trf_id"  :  Constant.constantVariables.trfID,
             "mode"              : Constant.modeValues.createMode,
             "to_city"           : Constant.constantVariables.to_city,
             "from_city"         : Constant.constantVariables.from_city,
             "description"       : Constant.constantVariables.descrption,
             "request_type"      : Constant.constantVariables.request_type,
             "to_date"           : Constant.constantVariables.to_date!,
             "from_date"         : Constant.constantVariables.from_date!,
             "travel_configs"    :  [["Config_id" : "9","values" : "train",
                                      "Config_id" : "10","values" : "bus"]]]

为什么？因为您的服务器需要一个字典数组，而您只发送一个字典；）
