在POST中使用manager.request [英] Using manager.request with POST

问题描述

我想使用Alamofire SessionManager 发送 POST 请求。

I want to send a POST request with Alamofire SessionManager.

我阅读了关于
的文件 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。

but I don't see an example for using request and POST, only upload.

它给出的例子：

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，方法：.post，参数：参数，编码：.url）
.responseJSON {
中的回复履行（回复）
}


符合方法签名（据我所知）但我在调用中收到错误额外参数方法：。

which conforms to the method signature (from what I can tell) but I get an error "Extra parameter method: in call.

推荐答案

你需要符合 URLRequest ，并将您的参数放在正文中数据

You need conform URLRequest with your parameters in body as 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)
        }

希望这会有所帮助
