AFNetworking网络请求的get和post步骤

 

1.首先通过第三方:CocoaPods下载AFNetworking

1.1.先找到要查找的三方库:pod search + AFNetworking

1.2.出来一堆列表页面,选择三方库最新版本命令,例如: pod ‘MBProgressHUD’,’~>0.8’  (:q 返回)

1.3.创建工程,进入工程: cd + 工程路径

1.4.编辑工程的Podfile文件: vim Podfile

1.5.(platform :iOS, ‘8.0’
target “工程名” do
pod ‘AFNetworking’, ‘~> 3.1.0’
end)新版本 (编辑键i)->(Esc键: 输入:wq返回)

1.6.6.保存Podfile的设置,然后进行更新下载三方库: pod update

2.进入工程进行相关操作

  1 // 网络请求的头文件
  2 #import <AFNetworking.h>
  3 @interface ViewController ()
  4
  5 {
  6     // 进行网络监测判断的bool值
  7     BOOL isOpen;
  8 }
  9
 10 // 用于网络请求的Session对象
 11 @property (nonatomic, strong) AFHTTPSessionManager *session;
 12
 13
 14 @end
 15
 16 @implementation ViewController
 17
 18 - (void)viewDidLoad {
 19     [super viewDidLoad];
 20     // 初始化Session对象
 21     self.session = [AFHTTPSessionManager manager];
 22     // 设置请求接口回来的时候支持什么类型的数据
 23     self.session.responseSerializer.acceptableContentTypes = [NSSet setWithObjects:@"application/json", @"text/json", @"text/javascript",@"application/x-json",@"text/html", nil];
 24 }
 25
 26 #pragma mark - 网络监测按钮的响应方法
 27 - (IBAction)NetworkmonitoringAction:(id)sender {
 28
 29     if (!isOpen) {
 30         //打开网络监测
 31         [[AFNetworkReachabilityManager sharedManager] startMonitoring];
 32
 33         isOpen = YES;
 34
 35
 36     } else {
 37         // 关闭网络监测
 38         [[AFNetworkReachabilityManager sharedManager] stopMonitoring];
 39
 40         isOpen = NO;
 41
 42     }
 43
 44     // 接下来会判断当前是WiFi状态还是3g状态,网络不可用状态
 45     [[AFNetworkReachabilityManager sharedManager] setReachabilityStatusChangeBlock:^(AFNetworkReachabilityStatus status) {
 46         switch (status) {
 47             case AFNetworkReachabilityStatusUnknown:
 48                 NSLog(@"当前网络处于未知状态");
