Alamofire请求使用以下命令进行调用：参数，标题和正文不起作用 [英] Alamofire Request call with: Parameters, Headers and Body not working

问题描述

关于以下Alamofire代码，我有两个问题。

即使我在参数中有action = heartbeat，但我删除了URL末尾的？action = heartbeat，我的JSON也失败了，为什么？

如何在下面的AF.request代码中添加我的JSON数据/正文？

  let urlString = https://intelipos.dynalias.net/ioc/rest.asp?action=heartbeat 
 let参数= [ action： heartbeat] 
 let标头：HTTPHeaders = [ Content-Type： application / json] 
 
 AF.request（urlString，方法：.post，参数：参数，编码：URLEncoding.httpBody，标头：标头）.responseJSON {response在
转换response.result {
 case .success：
 print（ Validation Success）
 case let .failure（error）：
 print（error）
} 
} 
  

解决方案

问题一

您需要编码为查询字符串

< pre class = lang-swift prettyprint-override> let urlString = https://intelipos.dynalias.net/ioc/rest.asp
let参数= [ action：心跳]
let标头：HTTPHeaders = [ Content-Type ： application / json]

AF.request（urlString，方法：.post，参数：参数，编码：URLEncoding.queryString，标头：标头）.responseJSON {在
中响应切换response.result {
case .success：
print（ Validation Success）
case let .failure（error）：
print（error）
}
}


第二个问题

您必须准备一个可编码模型并将其传递给 parameters 参数并将编码设置为 JSONEncoding.default

I have two questions with regards to the Alamofire code below.

My JSON fails if I remove the ?action=heartbeat at the end of the URL even though I have action = heartbeat in the parameters, why?

How do I add my JSON data/body in the AF.request code below?

let urlString   = "https://intelipos.dynalias.net/ioc/rest.asp?action=heartbeat"
let parameters  = ["action":"heartbeat"]
let headers: HTTPHeaders = ["Content-Type":"application/json"]

AF.request(urlString, method: .post, parameters: parameters, encoding:  URLEncoding.httpBody, headers: headers).responseJSON { response in
  switch response.result {
  case .success:
    print("Validation Successful")
  case let .failure(error):
    print(error)
  }
}

解决方案

Question One

You need to encode as a querystring

let urlString   = "https://intelipos.dynalias.net/ioc/rest.asp"
let parameters  = ["action":"heartbeat"]
let headers: HTTPHeaders = ["Content-Type":"application/json"]

AF.request(urlString, method: .post, parameters: parameters, encoding:  URLEncoding.queryString, headers: headers).responseJSON { response in
  switch response.result {
  case .success:
    print("Validation Successful")
  case let .failure(error):
    print(error)
  }
}

Question Two

You have to prepare an encodable model and pass it in parameters argument and set encoding to JSONEncoding.default
