我需要为我的应用程序提供付款方式，并且必须发布带有JSON数据的请求才能与API进行通信。一切对我来说似乎都是正确的。我在代码中找不到任何错误，但是我认为JSON没有按顺序发布。这重要吗？因为响应表示失败，但我找不到其他东西。如果JSON顺序很重要，我该怎么做？我是新手，请帮助我。这是我的代码：
func mainRequestForPayment() {
)
let headers: HTTPHeaders = [
"accept": "application/json",
"content-type": "application/json",
"authorization": "\(self.authValue)",
"x-iyzi-rnd": "\(self.randomString)",
"cache-control": "no-cache"
]
let url = "MY_URL"
let parameters: [String: Any] = [
"locale": "tr",

],
"buyer": [

Alamofire.request(url, method: .post, parameters: parameters , encoding: JSONEncoding.default, headers: headers)
.responseJSON { (response) in
print(parameters)
switch response.result {
case .success(let value):
let swiftyJson = JSON(value)
print ("return as JSON using swiftyJson is: \(swiftyJson)")
case .failure(let error):
print ("error: \(error)")
}
}
}
我看不到我的错在哪里？再有什么办法可以在发布请求中下订单？谢谢大家
我得到那个回应：
return as JSON using swiftyJson is: {
"conversationId" : "123456789",
"locale" : "tr",
"errorCode" : "1000",
"status" : "failure",
"systemTime" : 1579858355103,
"errorMessage" : "Invalid signature"
}
JSON顺序通常并不重要，因为JSON规范并未将其定义为JSON对象的要求，但是某些设计欠佳的后端确实需要它。您确实需要检查与之通信的后端的要求。
此外，Swift的Dictionary类型是任意排序的，并且该顺序可能在应用程序运行之间以及用于编译代码的Swift版本之间改变。
最后，Swift的JSONEncoder和Apple的JSONSerialization类型都无法提供要求严格订购的方法。最多JSONSerialization提供.sortedKeys选项，这将为您提供有保证的（字母顺序）顺序，但可能不是您在其中声明参数的顺序。Encoder如果您有Codable类型（我建议使用它而不是SwiftyJSON），则使用Alternative可以给出您可以更好地保证订单秩序，但是只有在后端需要时，才应该真正在乎。
顺便说一句，我建议您使用静态HTTPHeader属性作为HTTPHeaders值，而不是使用原始字符串，这样会更加方便。例如：
let headers: HTTPHeaders = [.accept("application/json"),
.contentType("application/json")]
