查询Alamofire中的参数

Question

在我的iOS应用程序中,我使用Alamofire 4并想要使用查询参数向后端发送请求.但是Alamofire转换了"？" 在url查询中的"%3F"(http:// blahblahblah/mobile-proxy/authorizations%3FphoneNumber = + 555555555&userID = agent),我从后端收到404错误.我读到了有关URLEncoding的内容,但是我找不到任何方法可以将它与URLRequest一起使用,因为我使用带有URLRequest的自定义路由器枚举文件.这是我的路由器文件的一部分:

func asURLRequest() throws -> URLRequest {

        let url = try Router.baseUrl.asURL()

        var urlRequest = URLRequest(url: url.appendingPathComponent(path))
        urlRequest.httpMethod = method.rawValue

        switch self {

        case .authorizations:
            urlRequest.setValue("application/json", forHTTPHeaderField: "Content-Type")
            urlRequest.setValue(getHeaderCredentials().operationID, forHTTPHeaderField: Constants.operationID)
            urlRequest.setValue(getHeaderCredentials().appCode, forHTTPHeaderField: Constants.appCode)
        case .startAuthentication, .startContractOperation:
            urlRequest.setValue("application/json", forHTTPHeaderField: "Content-Type")
            urlRequest.setValue(getHeaderCredentials().appCode, forHTTPHeaderField: Constants.appCode)
        case .operationAllowance:
            urlRequest.setValue("application/json", forHTTPHeaderField: "Content-Type")
        default:
            break
        }

        switch self {

        case .authorizations:
            urlRequest = try Alamofire.URLEncoding.queryString.encode(urlRequest, with: nil)
        default:
            break
        }

        return urlRequest
    }

我尝试Alamofire.URLEncoding.queryString.encode,但它不起作用.

你需要创建你的网址字符串并设置URLEncoding之类的

let urlwithPercent = yourURlString.addingPercentEncoding( withAllowedCharacters: NSCharacterSet.urlQueryAllowed())
var urlRequest = URLRequest(url: URL(string: urlwithPercent))

这里yourURlString是一个完整的URL作为字符串(http:// blahblahblah/mobile-proxy/authorizations%3FphoneNumber = + 555555555&userID = agent)
