如何使用 Alamofire 4 在 Swift 3 中发送带有参数和正文的 JSON 数据的 POST 请求? [英] How to send POST request with both parameter and body for JSON data in Swift 3 using Alamofire 4?

问题描述

Postman api url 添加到下面.

Postman api url added below.

当前代码:

let baseUrl = "abc.com/search/"
let param  =  [
        "page":"1",
        "size":"5",
        "sortBy":"profile_locality"
    ]

    let headers = [
        "Content-Type": "application/json"
    ]


    Alamofire.SessionManager.default.request("(baseUrl)field", method: .post,parameters: param, encoding: JSONEncoding.default, headers: headers).responseJSON { response in
        print(response.request ?? "no request")  // original URL request
        if(response.response?.statusCode != nil){
            print("done")
            if self.checkResponse(response.response!.statusCode){
                let json = JSON(data: response.data!)
                //print("at_LeadStop json (json)")
                return completionHandler(json, false)

            } else {
                return completionHandler(JSON.null, true)
            }
        } else {
            print("gone")
            return completionHandler(JSON.null, true)
        }}

我不知道如何通过此代码添加正文请求.请帮我解决这个问题.

I don't know how to add body request through this code. Please help me to slove this problem.

推荐答案

你在这里混合了两件事，page、size 和 sortBy您是否需要将 url 字符串作为查询字符串传递.现在您的主体请求是 JSON 数组，并且您可以仅使用 URLRequest 使用 Alamofire 发布数组.所以试试这样.

You are mixing two things here, page,size and sortBy is you need to pass with the url string as query string. Now your body is request is JSON Array and you can post array with Alamofire only using URLRequest. So try like this.

let baseUrl = "abc.com/search/"
let queryStringParam  =  [
    "page":"1",
    "size":"5",
    "sortBy":"profile_locality"
]
//Make first url from this queryStringParam using URLComponents
var urlComponent = URLComponents(string: baseUrl)!
let queryItems = queryStringParam.map  { URLQueryItem(name: $0.key, value: $0.value) }
urlComponent.queryItems = queryItems

//Now make `URLRequest` and set body and headers with it
let param = [
    [
        "fieldName" : "abc",
        "fieldValue":"xyz"
    ],
    [
        "fieldName" : "123",
        "fieldValue":"789"
    ]
]
let headers = [ "Content-Type": "application/json" ]
var request = URLRequest(url: urlComponent.url!)
request.httpMethod = "POST"
request.httpBody = try? JSONSerialization.data(withJSONObject: param)
request.allHTTPHeaderFields = headers

//Now use this URLRequest with Alamofire to make request
Alamofire.request(request).responseJSON { response in
    //Your code
}
