GET请求
class func zyGETWithURLSession(_ urlString:String,parmas:NSDictionary,mathFunction:@escaping (_ responObject:AnyObject)->Void){
let session = URLSession.shared;
let str = self.parmasStringWithParmas(parmas);
let url = URL(string: String(format: "%@?%@", urlString,str));
let task = session.dataTask(with: url!, completionHandler: { (data, respons, eror) -> Void in

mathFunction(responsobject! as AnyObject);
}else{
mathFunction("file" as AnyObject);
}
})
task.resume();
}
POST请求
class func zyPOSTwithURLSession(_ urlString:String,parmas:NSDictionary,mathFunction:@escaping (_ responObject:AnyObject)->Void){
let session = URLSession.shared;
let str = self.parmasStringWithParmas(parmas);
let url = URL(string: urlString);

mathFunction(responsobject! as AnyObject);
}else{
mathFunction("file" as AnyObject);
}
})
task.resume();
}
拼接GET参数
class func parmasStringWithParmas(_ parmas:NSDictionary)->NSString{
let parString = NSMutableString();
let arr = parmas.allKeys as NSArray;
for i in 0 ..< arr.count{
let key = arr[i] as! String;
let value = parmas.object(forKey: arr[i]) as! NSString;
parString.appendFormat("%@=%@", key,value);
let lastKey = arr.lastObject as! String;
if (key != lastKey) {
parString.appendFormat("&");
}
}
return parString;
}
设置请求头
request.setValue(fileType, forHTTPHeaderField: "Content-Type");
上传方法
class func uploadFile(_ urlString:String,_ fileType:String,_ filePath:String,_ mathFunction: @escaping zymathFuncation){
let session = URLSession.shared;
let url = URL.init(string: urlString);
var request = URLRequest(url: url!);
request.httpMethod = "POST";
request.setValue(fileType, forHTTPHeaderField: "Content-Type");
let filedata:Data = try!Data.init(contentsOf: URL.init(fileURLWithPath: filePath));
let task = session.uploadTask(with: request, from: filedata) { (data, response, error) in
}
task.resume();
}
删除方法
class func deletFile(urlString:String,_ mathFunction: @escaping zymathFuncation){
let session = URLSession.shared;
let url = URL(string: urlString);
var request = URLRequest(url: url!);
request.httpMethod = "DELETE";
let task = session.dataTask(with:request, completionHandler: { (data, respons, error) -> Void in
})
task.resume();
}
更新方法
class func zyUpwithURLSession(_ urlString:String,parmas:Dictionary<String,Any>,mathFunction:@escaping (_ responObject:AnyObject,_ isSuccess:Bool,_ zyError:Error?)->Void){
let session = URLSession.shared;
let url = URL(string: urlString);
var request = URLRequest(url: url!);
request.httpMethod = "PUT";
let jsonData = try?JSONSerialization.data(withJSONObject: parmas, options: JSONSerialization.WritingOptions.prettyPrinted);
request.httpBody = jsonData! as Data;
let task = session.dataTask(with:request, completionHandler: { (data, respons, error) -> Void in
})
task.resume();

注意，3.0以后，session不能使用NSRequest和NSMutableRequest的对象。
