对于Http的编码统一

-(void)httpSample1{
    /********
     * self不会释放，直到block释放self才释放，因为block中有对self的强引用
     *******/
    HttpRequest *request = [[HttpRequest alloc] init];
    [request setStrUrl:@"http://192.168.1.129:9097/api/dog/device/fence/effectiveTimes"];
    [request setCompletionBlockWithType:HttpTypeGet success:^(HttpResponse *response) {
        self.textView.text = @"succ";
        NSLog(@"current thread :%@",[NSThread currentThread]);
    } failure:^(HttpResponse *response) {
        self.textView.text = response.errorDescription;
        NSLog(@"error :%@",response.errorDescription);
    }];
}
-(void)httpSample2{
    /********
     * self先释放，strongself变为nil,block回调时不会改变strongself的成员变量值
     *******/
    HttpRequest *request = [[HttpRequest alloc] init];
    [request setStrUrl:@"http://192.168.1.129:9097/api/dog/device/fence/effectiveTimes"];
    __weak FrameworkDemoVC *weakSelf = self;
    [request setCompletionBlockWithType:HttpTypeGet success:^(HttpResponse *response) {
        __strong FrameworkDemoVC *strongSelf = weakSelf;
        strongSelf.textView.text = @"succ";
        NSLog(@"current thread :%@",[NSThread currentThread]);
    } failure:^(HttpResponse *response) {
        __strong FrameworkDemoVC *strongSelf = weakSelf;
        strongSelf.textView.text = response.errorDescription;
        NSLog(@"error :%@",response.errorDescription);
    }];
}

-(void)httpSample3{

     * 和httpSample2一个效果,故实际使用时使用httpSample3即可，无需再对weakSelf进行一次强引用
