【问题描述】：

当我想使用 Alamofire 从服务器获取数据时，它显示了一些错误

@IBAction func profile(_ sender: Any) 

    print(AuthService.instance.authToken)
    print(AuthService.instance.userEmail)
    let BEARER_HEADER2 = [
        "id":AuthService.instance.userEmail,
        "Authorization":AuthService.instance.authToken

        //"Content-Type": "application/json; charset=utf-8"
    ]
    print(BEARER_HEADER2)

    Alamofire.request("http://fiveorzero.ml/api/v1/user/user/profile",method: .get, parameters: nil,encoding:URLEncoding.default, headers: BEARER_HEADER2).responseJSON  response in
        switch response.result 
        case .success(let value):
            let swiftyJson = JSON(value)
            print(swiftyJson)
            print("Khabbab")

        case .failure(let error):
            debugPrint(response.result.error as Any)
            print ("error: \(error)")
        
    

$2y$10$CUWgHVpbt6oPUdBo7weofucUniXw9JZoIeWZ1hZiwAfymZASoNWyS 128 [“id”：“128”，“授权”：“$2y$10$CUWgHVpbt6oPUdBo7weofucUniXw9JZoIeWZ1hZiwAfymZASoNWyS”] 可选（Alamofire.AFError.responseSerializationFailed（Alamofire.AFError.ResponseSerializationFailureReason.jsonSerializationFailed（错误域 = NSCocoaErrorDomain 代码 = 3840 “字符 0 周围的值无效。” UserInfo = NSDebugDescription = 字符 0 周围的值无效。））） 错误：responseSerializationFailed(Alamofire.AFError.ResponseSerializationFailureReason.jsonSerializationFailed(Error Domain=NSCocoaErrorDomain Code=3840 "字符 0 周围的值无效。" UserInfo=NSDebugDescription=字符 0 周围的值无效))

【问题讨论】：

尝试用responseString替换responseJSON

您是否以与服务器所需格式相同的格式传递标头？

是的服务器想要token和id

还是不行

["id": "128", "Authorization": "$2y$10$CUWgHVpbt6oPUdBo7weofucUniXw9JZoIeWZ1hZiwAfymZASoNWyS"] 找不到页面

【参考方案1】：

您可以像这样使用创建标题

let id = "your id"
let Authorization = "your ascess token"
let credentialData = "\(id):\(Authorization)".data(using: String.Encoding.utf8)!
let base64Credentials = credentialData.base64EncodedString(options: [])
    let headers = ["Authorization": "Basic \(base64Credentials)"]

Alamofire.request("your url" , method : .post, parameters: parameters,
                      headers: headers)
        .responseJSON  response in
        // do whatever you want here
        switch response.result 
        case .failure(let error): break
        // self.popupp(elrtdata : "Please try again latter.")
        case .success(let responseObject):  

【讨论】：

不起作用，它说身份验证令牌不匹配！但在邮递员中，我可以使用授权令牌和 id 访问我的用户个人资料

【参考方案2】：

 Alamofire.request(URL, method: .get, encoding: JSONEncoding.default, headers: headers).responseJSON
                
                    response in
                    switch response.result
                    
                    case .success(let value):
                        completionHandler(value as? Array, nil)//completionHandler(value as? NSDictionary, nil)
                    print(value)
                    case .failure(let error):
                        completionHandler(nil,(error as NSError?)!)
