【中文标题】401 alamofire 获取带有标头的请求【英文标题】:401 alamofire get request with headers 【发布时间】:2018-04-05 04:54:22 【问题描述】:我在尝试使用自定义标头发出请求时遇到错误 401,当我打印标头时,它就在那里,就像我使用邮递员拨打电话一样,不同之处在于在邮递员中请求有效,但在app 我得到那个错误,我不认为它是标题,因为正如我所说的那样,它们在那里,我在这里缺少什么?
func getUserByID(completion: @escaping CompletionHandler)
let url_id = URL_USER_ID + String(self.userID)
let header:HTTPHeaders = [
"Content-Type": "application/json",
"Authorization": "Token " + AuthService.instance.authToken
]
Alamofire.request(url_id, method: .get, parameters: nil, encoding: JSONEncoding.default, headers: header).responseJSON
(response) in
guard let data = response.data else return
let json = try? JSON(data: data)
if response.response?.statusCode == 200
let user = json!["user"]
let id = user["id"].stringValue
let email = user["email"].stringValue
let img = user["img"].stringValue
let tipo_usuario = user["tipo_usuario"].intValue
let nome_comp = user["nome_comp"].stringValue

self.userEmail = email
self.userID = Int(id)!
completion(true)
else if response.response?.statusCode == 400
completion(false)
else
debugPrint(response.result.error as Any)
enter code here
以及错误信息:

【问题讨论】:
您正在使用form-data
或form-urlencoded
在邮递员中调用Web 服务?
error 401 表示授权问题,授权时也要传递用户名和密码
HTTP 401 表示请求未经授权。您还可以在detail
中看到the user credentials was not provided
。我假设授权方法是令牌,所以请查看 API 文档。应该是Token
吗?更常见的方案是Basic
或Bearer
端点使用什么形式的授权?检查iana schemes
它是“令牌”,该 api 是使用 django-rest 制作的,它可以与邮递员请求一起正常工作
【参考方案1】:
我遇到了类似的问题:
邮递员成功执行请求,但 alamofire
与401
JWT Token not found
。所以响应是失败的,但是服务器对请求执行了操作,就像它成功一样。
在我的例子中,结果是重定向。
您应该检查它是否不是由于重定向,因为默认情况下 Alamofire 不会将标头中的授权字段传递给重定向的请求(在这种情况下这似乎是合理的行为)。
因此,要使授权可传输,您可以这样做:
Alamofire.SessionManager.default.delegate.taskWillPerformHTTPRedirection = session, task, response, request in
var redirectedRequest = request
if let originalRequest = task.originalRequest,
let headers = originalRequest.allHTTPHeaderFields,
let authorizationHeaderValue = headers["Authorization"]
var mutableRequest = request
mutableRequest.setValue(authorizationHeaderValue, forHTTPHeaderField: "Authorization")
redirectedRequest = mutableRequest
return redirectedRequest
//now use your requests i.e:
Alamofire.request(url, method: .post, parameters: params, encoding: JSONEncoding.default, headers: header)
.validate()
.responseJSON(completionHandler: (response) in
switch response.result
case .success:
//success
break
case .failure(let error):
//fail
break
)
如果您只想简单地返回默认行为:
Alamofire.SessionManager.default.delegate.taskWillPerformHTTPRedirection = nil
