ios - 如何在 swift 上发出带有身份验证的 http 请求？

Question

IOS ucs

我需要发出带有身份验证的 http 请求。首先，我需要对以下 URL 进行 GET 操作: http://209.97.133.56/api/ucs但我需要通过身份验证来做到这一点。为此，我需要将以下标记放入某个 header 中

我来这里是为了寻求帮助，因为我做不到。

在这里，您只需添加授权 header

使用Codable对于 JSON 解析，不要使用 JSONSerialization 并使用此 tool用于将 Json 转换为 struct

let url = URL(string: "http://209.97.133.56/api/ucs")!
let token = "your token"
var request = URLRequest(url: url)
request.addValue("Bearer \(token)", forHTTPHeaderField: "Authorization")
request.addValue("application/json", forHTTPHeaderField: "Content-Type")
request.addValue("application/json", forHTTPHeaderField: "Accept")
request.httpMethod = "GET"


URLSession.shared.dataTask(with: request) { (data, response , error) in
    guard let data = data else { return }
    print(String(data: data, encoding: .utf8) ?? "Invalid JSON")
}.resume()

编辑

使用我给的工具将你的json转换为struct，工具转换后的JSON

struct UPS: Codable {
    let data: [UPSData]

    enum CodingKeys: String, CodingKey {
        case data = "data"
    }
}

struct UPSData: Codable {
    let id: String
    let unidadeCurricularID: Int
    let unidadeCurricularNome: String
    let unidadeCurricularAbreviatura: String
    let unidadeCurricularAtivo: Int
    let unidadeCurricularIDMapSiges: Int
    let anoCurricularID: Int
    let anoCurricularNome: String
    let anoCurricularAbreviatura: String?
    let anoCurricularAtivo: Int
    let anoCurricularIDMapSiges: Int
    let periodoTempoID: Int
    let periodoTempoNome: String
    let periodoTempoAvreviatura: String
    let periodoTempoOrdem: Int
    let periodoTempoAtivo: Int
    let periodoTempoIDMapSiges: String
    let numeroEstudante: Int
    let idAnoLetivo: Int
    let idUnidadeCurricular: Int
    let idEstadoInscricao: Int
    let idAnoCurricular: Int
    let numeroCreditos: Int

    enum CodingKeys: String, CodingKey {
        case id = "id"
        case unidadeCurricularID = "unidadeCurricularId"
        case unidadeCurricularNome = "unidadeCurricularNome"
        case unidadeCurricularAbreviatura = "unidadeCurricularAbreviatura"
        case unidadeCurricularAtivo = "unidadeCurricularAtivo"
        case unidadeCurricularIDMapSiges = "unidadeCurricularIdMapSiges"
        case anoCurricularID = "anoCurricularId"
        case anoCurricularNome = "anoCurricularNome"
        case anoCurricularAbreviatura = "anoCurricularAbreviatura"
        case anoCurricularAtivo = "anoCurricularAtivo"
        case anoCurricularIDMapSiges = "anoCurricularIdMapSiges"
        case periodoTempoID = "periodoTempoId"
        case periodoTempoNome = "periodoTempoNome"
        case periodoTempoAvreviatura = "periodoTempoAvreviatura"
        case periodoTempoOrdem = "periodoTempoOrdem"
        case periodoTempoAtivo = "periodoTempoAtivo"
        case periodoTempoIDMapSiges = "periodoTempoIdMapSiges"
        case numeroEstudante = "numeroEstudante"
        case idAnoLetivo = "idAnoLetivo"
        case idUnidadeCurricular = "idUnidadeCurricular"
        case idEstadoInscricao = "idEstadoInscricao"
        case idAnoCurricular = "idAnoCurricular"
        case numeroCreditos = "numero_creditos"
    }
}

在此类中添加所有网络请求代码

class NetworkRequest {


    func auth<T: Decodable>(with url: URL, token: String, completion: @escaping (T) -> Void) {

        var request = URLRequest(url: url)
        request.addValue("Bearer \(token)", forHTTPHeaderField: "Authorization")
        request.addValue("application/json", forHTTPHeaderField: "Content-Type")
        request.addValue("application/json", forHTTPHeaderField: "Accept")
        request.httpMethod = "GET"

        URLSession.shared.dataTask(with: request) { (data, response , error) in
            guard let data = data else { return }
            do {
                completion(try JSONDecoder().decode(T.self, from: data))
            } catch let error {
                print(error)
            }
        }.resume()

    }


}

在类里面的任何地方使用此代码

NetworkRequest().auth(with: url, token: token) { (ups: UPS) in
    print("do what do want to you")
}
