Question

我正尝试使用Alamofire发送带有正文的POST HTTP请求，希望能有所帮助。

我的身体：

{"data":{"gym":{"country":"USA","city":"San Diego","id":1}}}

我应该做这样的事情吗？

let parameters: [String: Any] = [ "data": [
  "gym": [
  "country":"USA",
  "city":"San Diego",
  "id":1
]]]

Alamofire.request(URL, method: .post, parameters: parameters, headers: headers())
  .responseJSON { response in
    print(response)
}

Answer 1

如果您希望以json格式发送参数，请使用encoding作为JSONEncoding。因此，在请求中添加用于编码的参数，如下所示：

Alamofire.request(URL, method: .post, parameters: parameters, encoding: JSONEncoding.default, headers: headers())
   .responseJSON { response in
    print(response)
}

希望有帮助...

尝试使用此方法将json字符串转换为字典

func convertToDictionary(text: String) -> [String: Any]? {
    if let data = text.data(using: .utf8) {
        do {
            return try JSONSerialization.jsonObject(with: data, options: []) as? [String: Any]
        } catch {
            print(error.localizedDescription)
        }
    }
    return nil
}

let str = "{\"data\":{\"gym\":{\"country\":\"USA\",\"city\":\"San Diego\",\"id\":1}}}"

let dict = convertToDictionary(text: str)

并在您的请求中将字典作为参数发送。

Alamofire.request(URL, method: .post, parameters: dict, headers: headers())
  .responseJSON { response in
    print(response)
}

我认为您应该尝试使用以下格式准备字典：

var gym = [String:Any]()
gym["country"] = "USA"
gym["city"] = "San"

var data = [[String:Any]]()
data.append(gym)
var metaData = [String:Any]()
metaData["data"] = data

Answer 4

您的parameters是错误的...

let parameters: [String: Any] = { "data": 
  {
    "gym": {
      "country":"USA",
      "city":"San Diego",
      "id":1
    }
  }
}

Alamofire.request(<YOUR-URL>,
                      method: .post,
                      parameters: parameters,
                      encoding: URLEncoding(destination: .queryString),
                      headers: <YOUR-HEADER>
      ).validate().responseString { response in
      switch response.result {
      case .success:

        debugPrint("Good to go.")
        debugPrint(response)

      case .failure:

        let errMsg = String(data: response.data!, encoding: String.Encoding.utf8)!
        debugPrint(errMsg)
        debugPrint(response)

      }
    }

希望此帮助。顺便说一句，在Alamofire 5中，debugPrint(response)可以打印出response.data directly。
