Question

我试图在我的项目中使用带有RxSwift的Moya

我正面临问题，网址包含＆＃34;？＆＃34;

此TargetType我已创建

private extension String {
    var URLEscapedString: String {
        return self.addingPercentEncoding(withAllowedCharacters: CharacterSet.urlHostAllowed)!
    }
}

enum TMDb {
    case discoverMovieList(page: Int)
    case discoverMovieDetail(moive: Movie)
}

extension TMDb: TargetType {
    var baseURL: URL { return URL(string: BASE_URL)! }

    var path: String {
        switch self {
        case .discoverMovieList(page: let page):
            return "discover/movie?api_key=\(API_KEY)&sort_by=release_date.desc&page=\(page)"
        }
    }
    var method: Moya.Method {
        return .get
    }
    var parameters: [String: Any]? {
        return nil
    }
    var sampleData: Data {
        switch self {
            case .discoverMovieList(page: _):
                return "test".data(using: .utf8)!
            case .discoverMovieDetail(moive: _):
                return "test1".data(using: .utf8)!
        }
    }
    var task: Task {
        return .request
    }
    var parameterEncoding: ParameterEncoding {
        return URLEncoding.default
    }

}

问题出在我提出请求时。 url路径返回以某种方式不正确

这是我从控制台获得的网址

Optional("https://api.themoviedb.org/3/discover/movie%3Fapi_key=58da429caf2e25e8ff9436665e2f0e36&sort_by=release_date.desc&page=1")

但正确的应该是

https://api.themoviedb.org/3/discover/movie?api_key=58da429caf2e25e8ff9436665e2f0e36&sort_by=release_date.desc&page=1

在处理＆＃34;？＆＃34;时出现了问题。（它成为％3F＆＃34;网址中的字符。我们怎样才能使它正常工作？

更新

这就是我称之为Moya的方式

let provider: RxMoyaProvider<TMDb>
    let persistentContainer: PersistentContainer

    func discoverMoiveList(for page: Int) {
        self.provider.request(TMDb.discoverMovieList(page: 1)) { (result) in
            print(result.value?.request?.url?.absoluteString ?? "no url")

        }
    }
}

Answer 1

问题不在于“？”。之所以发生这种情况是因为您在路径URL中使用了可选值。控制BASE_URL和API_KEY，它们不能是可选值。

Moya没有问题。这里是您的提供商的Moya-Logger结果：

Moya_Logger: [29/04/2017 15:48:22] Request: https://api.themoviedb.org/3/discover/movie%3Fapi_key=58da429caf2e25e8ff9436665e2f0e36&sort_by=release_date.desc&page=1

Server = openresty;
"X-RateLimit-Limit" = 40;
"X-RateLimit-Remaining" = 39;
"X-RateLimit-Reset" = 1493470113;
} }

Answer 2

Here您已经了解了如何在没有Opt()的情况下获取可选变量的主题。我更喜欢that创建extension的方式：

extension Optional {
    func asStringOrNilText() -> String {
        switch self {
        case .some(let value):
            return String(describing: value)
        case _:
            return "(nil)"
        }
    }

}

print(result.value?.request?.url?.absoluteString.asStringOrNilText())

Answer 3

你之后应该通过什么？作为参数，Moya知道如何正确构建URL。

  var path: String {
    switch self {
    case .discoverMovieList(page: let page):
        return "discover/movie"
    }
}
var method: Moya.Method {
    return .get
}
var parameters: [String: Any]? {
     switch self {
     case .discoverMovieList(page: let page):
       return "["api_key":"\(API_KEY)",
                "sort_by":"release_date.desc",
                "page":page]"
}
}
