Moya/Alamofire - 具有相同键的URL编码参数

Question

我正在使用Moya Swift框架构建在Alamofire之上的网络层.

目前,我正在尝试使用具有相同键的URL编码参数发送请求.

即 http://some-site/request?param=v1&param=v2&param=v3

我已经尝试将这些参数分组到Set或NSSet或Array这样但没有任何东西有助于实现所需的结果.

["param": ["v1", "v2", "v3"]];

["param": Set(arrayLiteral: "v1", "v2", "v3")]

任何帮助都可以通过Moya或Alamofire本身来体现.

编辑:这是一些示例代码,提供基本的想法:

Api路由器设置

import Moya

// MARK:- Enum Declaration

enum ApiRouter {
    case XAuth(login: String, password: String)
    case SomeRequest(params: [String])
}

// MARK:- Moya Path

extension ApiRouter: MoyaPath {
    var path: String {
        switch self {
        case .XAuth:
            return "/authorization"
        case .SomeRequest:
            return "/some-request"
        }
    }
}

// MARK:- Moya Target

extension ApiRouter: MoyaTarget {
    private var base: String {
        return "http://some-site"
    }
    var baseURL: NSURL {
        return NSURL(string: base)!
    }

    var parameters: [String: AnyObject] {
        switch self {
        case .XAuth(let login, let password):
            return [
                "email": login,
                "password": password
            ]
        case .SomeRequest(let params):
            return [
                "params": params
            ]
    }

    var method: Moya.Method {
        switch self {
        case .XAuth:
            return .POST
        case .SomeRequest,
            return .GET
        }
    }

    var sampleData: NSData {
        switch self {
        case .XAuth:
            return "{}".dataUsingEncoding(NSUTF8StringEncoding)
        case .ServiceRequests:
            return "{}".dataUsingEncoding(NSUTF8StringEncoding)
        }
    }
}

Api提供商设置

    let endpointsClosure = { (target: ApiRouter) -> Endpoint<ApiRouter> in
    let endpoint = Endpoint<ApiRouter>(
        URL: target.baseURL.URLByAppendingPathComponent(target.path).absoluteString!,
        sampleResponse: EndpointSampleResponse.Success(200, { target.sampleData }),
        method: target.method,
        parameters: target.parameters,
        parameterEncoding: parameterEncoding(target)
    )
    switch target {
    case .XAuth:
        return endpoint
    default:
        let token = "some-token"
        return endpoint.endpointByAddingHTTPHeaderFields(["Authorization": "Bearer: \(token)"])
    }
}

func parameterEncoding(target: ApiRouter) -> Moya.ParameterEncoding {
    switch target {
    case .XAuth:
        return .JSON
    case .SomeRequest:
        return .URL
    }
}

let apiProvider = MoyaProvider(endpointsClosure: endpointsClosure)

apiProvider.request(ApiRouter.SomeRequest(params: ["v1", "v2", "v3"], completion: { (data, statusCode, response, error) in
    /* ... */
})

谢谢.

Answer 1

所以我找到了一个实际上非常简单明了的解决方案.阅读Alamofire的文档我发现了这个:

由于没有关于如何编码集合类型的已发布规范,Alamofire遵循将[]附加到数组值的键(foo [] = 1&foo [] = 2)的约定,并附加方括号包围的键用于嵌套字典值(foo [bar] = baz).

因此,对于这种情况,有自定义 ParameterEncoding选项,它接受闭包,您可以实际指定自己希望如何形成参数的实现.

这是同一个问题和相同的答案.
