Use Array instead of Dictionary as JSON root container（使用Array而不是Dictionary作為Json根容器）

Moya使用Dictionary作為JSON數(shù)據(jù)的根容器.但是有時(shí)候你將需要發(fā)送JSON數(shù)組作為根元素。Moya中使用.custom 編碼參數(shù)

定義一個(gè)JsonArrayEncoding閉包:

var req = request.URLRequest
let JsonArrayEncodingClosure: (URLRequestConvertible, [String: Any]?) -> (URLRequest, Error?) = { request, data in
    do {
        let json = try JSONSerialization.data(withJSONObject: data!["jsonArray"]!, options: .prettyPrinted)
        req.setValue("application/json; charset=utf-8", forHTTPHeaderField: "Content-Type")
        req.httpBody = json
    } catch {
        return (req, nil)
    }
    return (req, nil)
}

配置target對(duì)象

var parameters: [String: Any]? {
    switch self {
    case .someAPI:
        return ["jsonArray": ["Yes", "What", "Abc"]]
    default:
    return nil
    }
}

var parameterEncoding: Moya.ParameterEncoding {
    switch self {
    case .someAPI:
        return ParameterEncoding.custom(JsonArrayEncodingClosure)
    default:
        return ParameterEncoding.json
    }
}

對(duì)于.someAPI端點(diǎn)，將會(huì)把數(shù)據(jù)作為Json 數(shù)組["Yes", "What", "Abc"]發(fā)送

總結(jié) 這小節(jié)的核心:

1. 在request中傳遞json數(shù)組數(shù)據(jù)
