我试图使用Alamofire将Dictionairy发布到我的后端:
这是我的代码:
func postCheckUserPhonenumbers(phonenumbers:[String], completionHandler: (([AnyObject?], AnyObject?) -> Void)) {
let urlString = Constant.apiUrl().stringByAppendingFormat(Constant.apiPostCheckUserPhonenumbers)
let phoneNumbersDictionary = phonenumbers.map({ ["number": $0] })
let json = JSON(phoneNumbersDictionary)
print(json)
Alamofire.request(.POST, urlString, parameters: phoneNumbersDictionary, encoding: .JSON).validate().responseJSON(completionHandler: {response in
if response.result.isSuccess{
if let json = response.result.value {
let json = JSON(json)
}
}
if response.result.isFailure{
}
})
}
它不会编译,因为phoneNumbersDictionairy不符合预期的参数:
然而,印刷品(json)印刷的正是我邮差中的印记。这是我要张贴的身体。 印刷声明:[
{
"number" : "85555512"
},
{
"number" : "85551212"
},
{
"number" : "55648583"
}
]
我的邮差:
我怎样才能实现这一目标?
答案 0 :(得分:0)
正如错误消息所述,phonenumbers.map({["number": $0]})
返回类型为[[String:String]]
的数组,正如您在附加的图像上看到的那样。
Alamorfire期望[String: AnyObejct]?
类型的数组作为参数。
但也许How to send a post request with body或Sending json array via alamofire可以帮到你。

我最终使用了这个:
func postCheckUserPhonenumbers(phonenumbers:[String], completionHandler: (([AnyObject?], AnyObject?) -> Void)) {
let urlString = Constant.apiUrl().stringByAppendingFormat(Constant.apiPostCheckUserPhonenumbers)
let phoneNumbersDictionary = phonenumbers.map({ ["number": $0] })
let inputJSON = try? NSJSONSerialization.dataWithJSONObject(phoneNumbersDictionary, options: [])
let request = NSMutableURLRequest(URL: NSURL(string: urlString)!)
request.setValue("application/json", forHTTPHeaderField: "Content-Type")
request.HTTPMethod = "POST"
request.HTTPBody = inputJSON
Alamofire.request(request).validate().responseJSON(completionHandler: {response in
if response.result.isSuccess{
if let value = response.result.value {
let json = JSON(value)
let jsonString = json.rawString()
if let users:Array<User> = Mapper<User>().mapArray(jsonString) {
completionHandler(users, nil)
} else {
completionHandler([nil], nil)
}
}
}
if response.result.isFailure{
let message = ApiMessage()
message.message = "No users found"
completionHandler([nil],message)
}
})
}
