Ios 如何使用Alamofire在swift中发布请求json正文？

我需要在json正文中为我的应用程序后端发出POST请求，但响应返回失败。我假设我的json格式或编码是错误的，但我不知道问题出在哪里。我尝试了很多不同的解决方案，但都没有找到一个有效的。有人能看到我的代码的哪一部分是导致失败的原因吗

let headers: HTTPHeaders = [
    "accept": "application/json",
    "content-type": "application/json",
    "authorization": self.authValue,
    "x-iyzi-rnd": self.randomString,
    "cache-control": "no-cache"
]


let parameters: [String: Any] = [

        ],
        "currency": "try"


]


Alamofire.request("https://api.iyzipay.com/payment/auth", method: .post, parameters: parameters, encoding: JSONEncoding.default, headers: headers).responseJSON(completionHandler: {
    response in response

    let jsonResponse = response.result.value as! NSDictionary
    print(jsonResponse)



})

发布请求json正文有什么不同的方法吗

尽量不要修改

接受

、

内容类型

和

缓存控制

标题，让Alamofire决定这些标题。只需发送

授权

和您需要的一切。当然，授权的标题也总是大写的。请先试用POSTMAN，然后检查。@Aditya我已经试过了，它给出了相同的错误。您试用过POSTMAN和相同的标题吗？如果它给你同样的错误，这是后端问题，而不是前端问题。你的代码似乎是正确的。让你的后端先和邮递员一起工作，当这种情况发生时，回到你的前端代码。
