Alamofire 4 Swift 3 ParameterEncoding Custom [英] Alamofire 4 Swift 3 ParameterEncoding Custom

问题描述

我将我的项目更新为Swift 3和Alamofire 4.我使用的是自定义编码，但它已改为其他编码方法。我无法找到替代/等同于此：

I updated my project to Swift 3 and Alamofire 4. I was using custom Encoding, but it's changed to other encoding methods. I am not able to find the alternative/equivalent to this:

alamoFire.request(urlString, method: HTTPMethod.post, parameters: [:], encoding: .Custom({
        (convertible, params) in

        let mutableRequest = convertible.URLRequest.copy() as! NSMutableURLRequest
        let data = (body as NSString).data(using: String.Encoding.utf8)
        mutableRequest.httpBody = data
        return (mutableRequest, nil)

    }), headers: headers()).responseJSON { (responseObject) -> Void in

        switch responseObject.result {
        case .success(let JSON):
            success(responseObject: JSON)

        case .failure(let error):
            failure(error: responseObject)
        }
    }

<我也尝试过制作URLRequest对象和简单请求它也给我错误

I also tried by making URLRequest object and simple request its also giving me errors

var request = URLRequest(url: URL(string: urlString)!)
    let data = (body as NSString).data(using: String.Encoding.utf8.rawValue)
    request.httpBody = data
    request.httpMethod = "POST"
    request.allHTTPHeaderFields = headers()

    alamoFire.request(request).responseJSON { (responseObject) -> Void in

        switch responseObject.result {
        case .success(let JSON):
            success(JSON)

        case .failure(let error):
            failure(responseObject, error)
        }
    }

请指点我的方向，如何将httpbody与Alamofire 4连接

Do point me in some direction, how to attach httpbody with the Alamofire 4

推荐答案

在Alamofire 4.0中你应该使用 ParameterEncoding 协议。这是一个例子，它使任何字符串 UTF8 可编码。

In Alamofire 4.0 you should use ParameterEncoding protocol. Here is an example, which makes any String UTF8 encodable.

extension String: ParameterEncoding {

    public func encode(_ urlRequest: URLRequestConvertible, with parameters: Parameters?) throws -> URLRequest {
        var request = try urlRequest.asURLRequest()
        request.httpBody = data(using: .utf8, allowLossyConversion: false)
        return request
    }

}

Alamofire.request("http://mywebsite.com/post-request", method: .post, parameters: [:], encoding: "myBody", headers: [:])
