我正在尝试从我的Django后端获取iOS应用中的数据。邮递员如果我对以下网址http://127.0.0.1:8000/api/places/categories 执行GET请求,并且参数为Key:"Authorization" Value: "Bearer access_token".
,我会收到JSON回复。
在我的应用程序中,我在Alamofire的帮助下做了类似的事情:
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)")
}
}
我收到错误消息未提供授权凭据。我理解这一点,它要求我传递参数,但参数只需要一个令牌。所以我做了这样的事情:
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)")
}
}
等待一段时间但无法获取数据并出现以下错误:
Response: nil
