将 manager.request 与 POST 一起使用

Question

我想向 Alamofire 发送POST请求 SessionManager .

我阅读了以下文档https://github.com/Alamofire/Alamofire/blob/master/Documentation/Alamofire%204.0%20Migration%20Guide.md#parameter-encoding-protocol

但我没有看到使用请求和POST的示例，只能上传。

它给出的示例：

let parameters: Parameters = ["foo": "bar"]
Alamofire.request(urlString, parameters: parameters) // Encoding => URLEncoding(destination: .methodDependent)
Alamofire.request(urlString, parameters: parameters, encoding: URLEncoding(destination: .queryString))
Alamofire.request(urlString, parameters: parameters, encoding: URLEncoding(destination: .httpBody))
// Static convenience properties (we'd like to encourage everyone to use this more concise form)
Alamofire.request(urlString, parameters: parameters, encoding: URLEncoding.default)
Alamofire.request(urlString, parameters: parameters, encoding: URLEncoding.queryString)
Alamofire.request(urlString, parameters: parameters, encoding: URLEncoding.httpBody)

我的代码是：

manager.request(url, method: .post, parameters: parameters, encoding: .url) .responseJSON { response in fulfill(response) }

它符合方法签名(据我所知(，但我收到错误"调用中method:了额外的参数。

您需要将

URLRequest与正文中的参数保持一致，Data

此代码可以帮助您

    var request = URLRequest(url: urlString!)
    request.httpMethod = "POST"
    request.setValue("application/json", forHTTPHeaderField: "Content-Type")
    request.httpBody = try! JSONSerialization.data(withJSONObject: parameters)
    manager.request(request)
           .responseJSON { response in
                fulfill(response)
        }

希望这有帮助
