我试图从我的Django后端获取iOS应用程序中的数据。在邮递员中，如果我对以下 URL执行GET请求，请
解决方案你在这里有一个错字：
let params = [Authorization：Bearer+ access_token]
您在持票人后缺少空格。
I am trying to fetch data in my iOS app from my Django backend. In postman if I perform a GET request on the following URL 127.0.0.1:8000/api/places/categories with the params being Key:"Authorization" Value: "Bearer access_token".I get a JSON response.
Inside my app I am doing something like this with the help of Alamofire:
let access_token = "123" let headers = ["Authorization": "Bearer" + access_token] Alamofire.request(self.categoriesUrl, method: .get, parameters:nil,encoding: JSONEncoding.default,headers: headers).response { response in print("Request: \(response.request)") print("Response: \(response.response)") print("Error: \(response.error)") if let data = response.data, let utf8Text = String(data: data, encoding: .utf8) { print("Data: \(utf8Text)") } }I get an error saying Authorization Credentials were not provided. I understand this and it asks me to pass in the parameters but the parameters just need a token. So I do something like this:
let access_token = "123" let params = ["Authorization": "Bearer" + access_token] Alamofire.request(self.categoriesUrl, method: .get, parameters:params,encoding: JSONEncoding.default,headers: nil).response { response in print("Request: \(response.request)") print("Response: \(response.response)") print("Error: \(response.error)") if let data = response.data, let utf8Text = String(data: data, encoding: .utf8) { print("Data: \(utf8Text)") } }It waits for a while but fails to fetch the data with the following error:
Response: nil Error: Optional(Error Domain=NSURLErrorDomain Code=-1001 "The request timed out." UserInfo={NSUnderlyingError=0x61800004b0d0 {Error Domain=kCFErrorDomainCFNetwork Code=-1001 "(null)" UserInfo={_kCFStreamErrorCodeKey=-2102, _kCFStreamErrorDomainKey=4}}, NSErrorFailingURLStringKey=127.0.0.1:8000/api/places/categories/, NSErrorFailingURLKey=127.0.0.1:8000/api/places/categories/, _kCFStreamErrorDomainKey=4, _kCFStreamErrorCodeKey=-2102, NSLocalizedDescription=The request timed out.}) Data:EDIT1:
解决方案You have a typo here :
let params = ["Authorization": "Bearer" + access_token]
You're missing a space after Bearer.
