Alamofire 4 Swift 3 GET request with parameters
提问by DungeonDev
I'm building a network stack using Alamofire 4 and Swift 3. Following the Alamofire guidelines I've created a router for the endpoints of the services. I'm currently using the free API of OpenWeatherMap but I'm finding problems in order to create a get request. That's the url needed: http://api.openweathermap.org/data/2.5/weather?q=Rome&APPID=MY_API_KEY. Pasted on a browser, and using a real API Key it works and gives me back my nice json full of info about the weather in the given location. On my App I can insert the parameters as Dictionary but I cannot find a way to append the api key at the end of the url.
我正在使用 Alamofire 4 和 Swift 3 构建网络堆栈。按照 Alamofire 指南，我为服务的端点创建了一个路由器。我目前正在使用 OpenWeatherMap 的免费 API，但为了创建获取请求，我发现了一些问题。这是所需的网址：http: //api.openweathermap.org/data/2.5/weather?q=Rome&APPID= MY_API_KEY。粘贴在浏览器上，并使用真正的 API 密钥，它可以工作并返回我的漂亮 json，其中包含有关给定位置的天气信息。在我的应用程序上，我可以将参数作为字典插入，但我找不到在 url 末尾附加 api 键的方法。
That's my enum router:
那是我的枚举路由器：
enum OWARouter: URLRequestConvertible {
case byCityName(parameters: Parameters)
// MARK: Url
static let baseURLString = "http://api.openweathermap.org"
static let apiKey = "MY_APY_KEY"
static let pathApiKey = "&APPID=\(apiKey)"
var method: HTTPMethod {
switch self {
case .byCityName:
return .get
}
}
var path: String {
switch self {
case .byCityName:
return "/data/2.5/weather"
}
}
// MARK: URLRequestConvertible
func asURLRequest() throws -> URLRequest {
let url = try OWARouter.baseURLString.asURL()
var urlRequest = URLRequest(url: url.appendingPathComponent(path))
switch self {
case .byCityName(let parameters):
urlRequest = try URLEncoding.default.encode(urlRequest, with: parameters)
print((urlRequest.url)!)
}
urlRequest.httpMethod = method.rawValue
return urlRequest
}
}
When I log my (urlRequest.url)! I have this: http://api.openweathermap.org/data/2.5/weather?q=Romebut I cannot find a way to add the apiKey. What am I doing wrong?
当我登录我的 (urlRequest.url) 时！我有这个：http: //api.openweathermap.org/data/2.5/weather?q=Rome 但我找不到添加 apiKey 的方法。我究竟做错了什么？
I've also made an ugly test adding this code after the print:
我还做了一个丑陋的测试，在打印后添加此代码：
var urlRequest2 = URLRequest(url: (urlRequest.url)!.appendingPathComponent(OWARouter.pathApiKey))
print("URL2: \(urlRequest2)")
And the log is URL2: http://api.openweathermap.org/data/2.5/weather/&APPID=My_API_KEY?q=RomeHow come the api key is in the middle?
并且日志是 URL2：http://api.openweathermap.org/data/2.5/weather/&APPID=My_API_KEY ?q=Rome api key 怎么在中间？
If you need this is the simple request code:
如果您需要这是简单的请求代码：
Alamofire.request(OWARouter.byCityName(parameters: ["q":"Rome"])).responseJSON { response in
print(response.request)
print(response.response)
print(response.data)
print(response.result)
debugPrint(response)
if let JSON = response.result.value {
print("json: \(JSON)")
}
}
Another question... If I use as parameters ["q":"Rome, IT"], my output url is: http://api.openweathermap.org/data/2.5/weather?q=Rome%2CIT
另一个问题...如果我用作参数 ["q":"Rome, IT"]，我的输出 url 是：http: //api.openweathermap.org/data/2.5/weather?q=Rome% 2CIT
How to keep the comma?
如何保留逗号？
Thank you!
谢谢！

Used below lines of code:
使用以下代码行：
func getRequestAPICall(parameters_name: String) {
let todosEndpoint: String = "your_server_url" + "parameterName=\(parameters_name)"
Alamofire.request(todosEndpoint, method: .get, encoding: JSONEncoding.default)
.responseJSON { response in
debugPrint(response)
if let data = response.result.value{
// Response type-1
if (data as? [[String : AnyObject]]) != nil{
print("data_1: \(data)")
}
// Response type-2
if (data as? [String : AnyObject]) != nil{
print("data_2: \(data)")
}
}
}
}

Swift - 5 Alamofire 5.0 Updated Code(just Change AF.request Method according to your requirement you can add Parameters headers and intercepter as well )
Swift - 5 Alamofire 5.0 更新代码（只需根据您的要求更改 AF.request 方法，您也可以添加参数标头和拦截器）
Alamofire.request(url, method: .get, encoding: JSONEncoding.default)
.responseJSON { response in
switch response.result {
case .success(let json):
print(json)
DispatchQueue.main.async {
// handle your code
}
case .failure(let error):
print(error)
}
}

func AlamofireGetCode()
{
var url:String!
url = "https://jsonplaceholder.typicode.com/comments"
Alamofire.request(url, method: .get, encoding: JSONEncoding.default)
.responseJSON { response in
switch response.result{
case .success(let json):
print(json)
DispatchQueue.main.async {
print(json)
self.mainarray = json as? NSArray
print(self.mainarray as Any)
self.mytableviewreload.reloadData()
}
case .failure(let error):
print(error)
}
}
}

I've found a solution... the Api Key is simply a parameter to send to the request. So the code to change is not in the router but in the request function:
我找到了一个解决方案...... Api Key 只是一个发送到请求的参数。所以要改变的代码不在路由器中，而是在请求函数中：
Alamofire.request(OWARouter.byCityName(parameters: ["q":"Rome","APPID":"MY_API_KEY"])).responseJSON { response in
print(response.request)
//print(response.response)
//print(response.data)
//print(response.result)
//debugPrint(response)
if let JSON = response.result.value {
print("json: \(JSON)")
}
}
EDIT: the comma issue do not gives me any problem now. Thank you.
编辑：逗号问题现在不给我任何问题。谢谢你。
