Ios 如何提取在Moya中失败的请求的url

mapObject来自哪里。我将响应映射到一个结构中（如果需要，可以使该结构可编码）

moya的响应是

结果

在

failure

中，您有

MoyaError

对象，它是

Enum

，您可以使用

switch-case

获得所有错误选项

    provider.request(.getRoot) { result in
        switch result {
        case .success(let response):
            print ("root \(response)")
            //            let response = try? response.mapObject(FolderResponse.self)
        //            print ("root \(response) \(response)")
        case .failure(let error):
            let r = result.0.request how do I get the request url from this context???
           ^^^^^^^^^^^^^^^^^^
            print("BaseURL: \(r)" + (error.errorDescription ?? "Unknown error"))
        }
    }

所以你可以像那样处理moya的错误

// A type representing possible errors Moya can throw.

public enum MoyaError: Swift.Error {

    /// Indicates a response failed to map to an image.
    case imageMapping(Response)

    /// Indicates a response failed to map to a JSON structure.
    case jsonMapping(Response)

    /// Indicates a response failed to map to a String.
    case stringMapping(Response)

    /// Indicates a response failed to map to a Decodable object.
    case objectMapping(Swift.Error, Response)

    /// Indicates that Encodable couldn't be encoded into Data
    case encodableMapping(Swift.Error)

    /// Indicates a response failed with an invalid HTTP status code.
    case statusCode(Response)

    /// Indicates a response failed due to an underlying `Error`.
    case underlying(Swift.Error, Response?)

    /// Indicates that an `Endpoint` failed to map to a `URLRequest`.
    case requestMapping(String)

    /// Indicates that an `Endpoint` failed to encode the parameters for the `URLRequest`.
    case parameterEncoding(Swift.Error)
}

不知怎的，我在404服务器上获得了成功。Moya bug？不是Moya bug只是在

TargetType

有

validationType

默认值是

none

只要使它成功即可CodeVar validationType:validationType{get}

provider.request(.getRoot) { result in
    switch result {
    case .success(let response):
        print ("root \(response)")
        //            let response = try? response.mapObject(FolderResponse.self)
    //            print ("root \(response) \(response)")
    case .failure(let error):
       self.handleMoyaError(error)
    }
}



//  here you canc heck all of this error
private func handleMoyaError(_ moyaError : MoyaError){

    switch moyaError {
    case let .statusCode(response):
        print(response.request?.url)
    case  .underlying(let nsError as NSError, let response): break
        // nsError  have URL  timeOut , no connection and cancel request
        //  just use response to map  of there is error
    default: break

    }
}
