我正在使用 alamofire 和 swift 3。我想返回从 Http 请求中获得的数据。目前我正在使用完成处理程序获取它。
func SendHttpRequest(params: AnyObject, header_obj: [String: String], url:String, http_method:HTTPMethod, completion: @escaping (_ response_value: JSON, _ error_type: String)->()) {
Alamofire.request(BASE_URL + url, method: http_method, parameters: (params as! [String : Any]) , encoding: URLEncoding.default, headers: header_obj).responseJSON { (response:DataResponse<Any>) in
switch(response.result) {
case .success( _ ):
if let jsonValue = response.result.value {
let json = JSON(jsonValue)
completion(json, "")
}
break
case .failure(_):
print(response.result.error!)
completion(JSON(response.result.value!), "NO_INT")
//"The Internet connection appears to be offline."
break
}
}//Alamofire
}//SendHttpRequest
但我想要的是返回我通过 Http 请求获得的任何结果。 例如:-
func GetUsers() -> [Users]{
//HERE IT SHOULD EXCUTE THE HTTP REQUEST AND RETURN THE USERS LIST
}
我怎样才能实现它？我可以像传递参数理论那样实现它吗？
最佳答案
我不太确定您的 json 是如何构建的，或者您的用户结构/类的外观如何，但是您应该做类似这样的事情。如果我理解正确你想做什么。
class NetworkingStuff {
func SendHttpRequest(params: AnyObject, header_obj: [String: String], url:String, http_method:HTTPMethod, success: @escaping (Any) -> (), failure: @escaping (error?) -> ()) {
Alamofire.request(BASE_URL + url, method: http_method, parameters: (params as! [String : Any]) , encoding: URLEncoding.default, headers: header_obj).responseJSON { (response:DataResponse<Any>) in
switch(response.result) {
case .success( _ ):
if let jsonValue = response.result.value {
let json = JSON(jsonValue)
success(json, "")
}
break
case .failure(_):
print(response.result.error!)
failure(JSON(response.result.value!), "NO_INT")
//"The Internet connection appears to be offline."
break
}
}
}
}
处理数据:
func GetUsers() -> [Users]? {
networkingStuff.sendHttpRequest(params: something, header_obj: dict, url: URL, http_method: Alamofire.post, success: { (responseData: Any) -> () in
if let data = responseData as? [String: Any], let users = data["users"] as? [String: Any] {
if let userArray = Users(dict: users) {
return userArray
} else {
return nil
}
}
}, failure: { (error: Any?) -> () in
return nil
})
}
