///////////////////////////以前用法/////////////////////////////////////////////////////////////
//使用AFHTTPRequestOperation 创建HTTP请求 --- GET请求
//1,url

//2,请求对象
NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString: URLTmp]];
//3，创建HTTP请求
AFHTTPRequestOperation *afOperation = [[AFHTTPRequestOperation alloc] initWithRequest:request];
//4,
afOperation.responseSerializer = [AFJSONResponseSerializer serializer];
//5,开始请求
[afOperation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {
//将字符串 编码后 转成 NSData
NSData *resData = [[NSData alloc] initWithData:[operation.responseString dataUsingEncoding:NSUTF8StringEncoding]];
//系统自带JSON解析
NSDictionary *resultDic = [NSJSONSerialization JSONObjectWithData:resData options:NSJSONReadingMutableLeaves error:nil];
NSLog(@"%@",resultDic);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(@"Failure: %@", error);
}];
//6,
[[NSOperationQueue mainQueue] addOperation:afOperation];
//------批量处理
// NSMutableArray *mutableOperations = [NSMutableArray array];
// for (NSURL *fileURL in filesToUpload) {
// NSURLRequest *request = [[AFHTTPRequestSerializer serializer] multipartFormRequestWithMethod:@"POST" URLString:@"http://example.com/upload" parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
