Question

我在使用Alamofire发送POST请求时遇到问题。我需要将usser和密码字段作为application / x-www-form-urlencode发送，并在URL中发送一些查询数据。

我正在创建一个URLRequest来处理该过程，但是我总是从服务器收到400响应，所以我想问题一定出在我创建请求的方式上。

这是邮递员中的示例：我需要在url中发送一个参数，并在application / x-www-form-urlencode中发送另外两个参数

Postman 1 - Parameters Postman 2 - ContentType

我需要执行此操作（在Android中是这样）

@FormUrlEncoded
    @POST(Constants.AUTH_LDAP)
    Call<ResponseBody> authLdap(
            @Query(value = Constants.PARAM_REQ, encoded = true) String req,
            @Field(Constants.PARAM_LOGIN) String login,
            @Field(Constants.PARAM_PASSWORD) String password
    );

这就是我很快拥有的

let queryParamters  =  [Constants.Params.PARAM_REQ:req]
let headers = ["Content-Type": "application/x-www-form-urlencoded"]
let fieldParameters = [
    Constants.Params.PARAM_LOGIN : user,
    Constants.Params.PARAM_PASSWORD : pass]

let url = URL(string: Constants.EndPoints.AUTH_LDAP)
let request = URLRequest(url: url!)
let encoding = try URLEncoding.default.encode(request, with: queryParamters as Parameters)
let encodingpa = try URLEncoding.httpBody.encode(request, with: fieldParameters as Parameters)
var urlRequest = encodingpa
urlRequest.url = encoding.url
urlRequest.allHTTPHeaderFields = headers
Alamofire.request(urlRequest).responseData(completionHandler: { response in
        switch response.result {
            case .success:
            print("sucess")
            print(response.response)
            case .failure(let error):
            print(error)
        }
    })

感谢您的帮助。

尝试使用类似URLComponents的查询参数创建url

var urlComponents = URLComponents(string: Constants.EndPoints.AUTH_LDAP)!
urlComponents.queryItems = [
  URLQueryItem(name: Constants.Params.PARAM_REQ, value: req)
]

let headers = ["Content-Type": "application/x-www-form-urlencoded"]
var request = URLRequest(url: urlComponents.url!)
request.httpMethod = "POST"
request.httpBody = try? JSONSerialization.data(withJSONObject: fieldParameters)
request.allHTTPHeaderFields = headers

Alamofire.request(request).responseJSON { response in

}

Alamofire多个参数（查询和表单）Swift 4
