请检查是否有问题 我有一段代码使用API获取电影列表,但是什么也没发生。
typealias JSONDictHandler = (([String : Any]?) -> Void)
let session = URLSession(configuration: .default)
var request = URLRequest(url: URL(string: "http://dev.bsp.vn:8081/training-movie/movie/list")!)
let token = "dCuW7UQMbdvpcBDfzolAOSGFIcAec11a"
request.httpMethod = "GET"
request.setValue(token, forHTTPHeaderField: "app_token")
let dataTask = session.dataTask(with: request) { (data, response, error) in
// if nothing wrong
if error == nil {
if let httpResponse = response as? HTTPURLResponse {
switch httpResponse.statusCode {
case 200: // successful case
if let data = data {
do {
let jsonDict = try JSONSerialization.jsonObject(with: data, options: .mutableContainers)
print(jsonDict)
} catch let error as NSError {
print("Error: \(error.localizedDescription)")
}
}
default:
print("HTTP Response Code: \(httpResponse.statusCode)")
}
}
// there's something wrong
} else {
print("Error: \(String(describing: error?.localizedDescription))")
}
}
dataTask.resume()
此外,我必须在网址中插入一些参数,我该怎么做?
