NSURLSession实际请求

iOS9使用http请求方法:

  1. 在工程info.plist文件内添加NSAppTransportSecurity键,类型为dictionary
  2. 在NSAppTransportSecurity中添加NSAllowsArbitraryLoads键,值为YES

GET请求

        let key = "a27383fa93bd3cc57ff4a180036d56ac"
let urlString = "http://v.juhe.cn/xianxing/citys"
let url = NSURL(string: urlString + "?key=" + key) // 创建请求对象
let request = NSURLRequest(URL: url!) // 获取会话对象
let session = NSURLSession.sharedSession() // 创建请求任务
let task = session.dataTaskWithRequest(request) { (data, response, error) in
if let jsonData = data {
do {
let dic = try NSJSONSerialization.JSONObjectWithData(jsonData, options: NSJSONReadingOptions.MutableContainers) as? [String : AnyObject]
print(dic)
} catch { }
}
} // 执行任务
task.resume()

POST请求

        let urlString = "http://v.juhe.cn/carzone/series/query"
let url = NSURL(string: urlString) // 创建请求对象
let request = NSMutableURLRequest(URL: url!)
// 设置请求模式
request.HTTPMethod = "POST"
// 设置请求体
request.HTTPBody = "action=getCarAllBrand&key=afdfb2885044bf2e14b24c293012bbea".dataUsingEncoding(NSUTF8StringEncoding) // 获取会话对象
let session = NSURLSession.sharedSession() // 创建请求任务
let task = session.dataTaskWithRequest(request) { (data, response, error) in
if let jsonData = data {
do {
let dic = try NSJSONSerialization.JSONObjectWithData(jsonData, options: NSJSONReadingOptions.MutableContainers) as? [String : AnyObject]
print(dic)
} catch { }
}
} // 执行任务
task.resume()
