浅谈IOS中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

// 网络请求的头文件
#import <AFNetworking.h>
@interface ViewController ()

{
  // 进行网络监测判断的bool值
  BOOL isOpen;
}

// 用于网络请求的Session对象
@property (nonatomic, strong) AFHTTPSessionManager *session;


@end

@implementation ViewController

- (void)viewDidLoad {
  [super viewDidLoad];
  // 初始化Session对象
  self.session = [AFHTTPSessionManager manager];
  // 设置请求接口回来的时候支持什么类型的数据
  self.session.responseSerializer.acceptableContentTypes = [NSSet setWithObjects:@"application/json", @"text/json", @"text/javascript",@"application/x-json",@"text/html", nil];
}

#pragma mark - 网络监测按钮的响应方法
- (IBAction)NetworkmonitoringAction:(id)sender {
  
  if (!isOpen) {
    //打开网络监测
    [[AFNetworkReachabilityManager sharedManager] startMonitoring];
    
    isOpen = YES;
    
    
  } else {
    // 关闭网络监测
    [[AFNetworkReachabilityManager sharedManager] stopMonitoring];
    
    isOpen = NO;
    
  }
  
  // 接下来会判断当前是WiFi状态还是3g状态,网络不可用状态
  [[AFNetworkReachabilityManager sharedManager] setReachabilityStatusChangeBlock:^(AFNetworkReachabilityStatus status) {
    switch (status) {
      case AFNetworkReachabilityStatusUnknown:
        NSLog(@"当前网络处于未知状态");
        break;
      case AFNetworkReachabilityStatusNotReachable:
        NSLog(@"当前网络处于未链接状态");
        break;
      case AFNetworkReachabilityStatusReachableViaWWAN:
        NSLog(@"手机流量网络");
        break;
      case AFNetworkReachabilityStatusReachableViaWiFi:
        NSLog(@"wifi状态");
        break;
      default:
        break;
    }
  }];
  
}
