@end使用方法：
先导入头文件 #import "ZJLAFRequest.h"
以post请求为例子：
NSString *hostString = @"xxxxx";
NSMutableDictionary *dic = [NSMutableDictionary dictionaryWithObjectsAndKeys:@"22",@"userid",nil];
ZJLAFRequest *httpReauest = [ZJLAFRequest sharedInstance];
[httpReauest POST:hostString dict:dic progressFloat:^(float progressFloat){
}succeed:^(id responseObject) {
//请求成功以后
} failure:^(NSError *error) {
//请求失败
NSLog(@"%@", error);
}];
