ios - Alamofire httpBody 在 swift 5 中显示 500 statusCode

Question

我用的是Alamofire 5，我把参数放到了httpbody。我已经在 Postman 中运行它，并且运行良好。我的 body 参数如下。

{
"user_id": "user_id",
"username": "user_name",
"password": "pass",
"token": "",
"type_id": 100,
"country_id": 1,
"language_id": 1,
"customer_id": 1,
"parent_user_id": "",
"profile": {}
 }

我使用下面的代码使用 Alamofire 5 发出请求。这是代码:

func change_password() {

let headers: HTTPHeaders = [
    "Content-Type": "application/json",
    "YumaSession": Global_Variable.globalValue.session_id
]
let parameters:Parameters = [
    "user_id": "user_id",
    "username":  "username",
    "password": txtPassword.text!,
    "token": "",
    "type_id": 100,
    "country_id": 1,
    "language_id": 1,
    "customer_id": 1,
    "parent_user_id": "",
    "profile": []
]

AF.request( url,method: .put,parameters: parameters,encoding: URLEncoding.httpBody,headers: headers).responseJSON{ response in

    switch response.result {
    case .success(let responseData):
        print("responseData-->",response.response!.statusCode)
    case .failure(let error):
        print("error--->",error)
    }
    }
   }

以上代码返回 500 状态码。代码上面有什么问题？

parameters.profile 是用数组文字而不是字典文字定义的。固定代码如下。

let parameters:Parameters = [
    "user_id": "user_id",
    "username":  "username",
    "password": txtPassword.text!,
    "token": "",
    "type_id": 100,
    "country_id": 1,
    "language_id": 1,
    "customer_id": 1,
    "parent_user_id": "",
    "profile": [:]
]
