Brief Discussion on AFNetworking Network Request GET and POST Steps in iOS

1.Firstly, download AFNetworking through the third-party: CocoaPods

1.1.First find the third-party library to be searched: pod search + AFNetworking

1.2.A list of pages appears, select the command for the latest version of the third-party library, for example: pod ‘MBProgressHUD’,'~>0.8''　 (:q to return)

1.3.Create the project, enter the project: cd + Project path

1.4.Edit the Podfile file of the project: vim Podfile

1.5.(platform :iOS, ‘8.0'
target “工程名” do
pod ‘AFNetworking', ‘~> 3.1.0'
end)New version (Edit key i)-(Esc key: Enter:wq to return)

1.6.6.Save the settings of Podfile and then update and download third-party libraries: pod update

2.Enter the project for related operations

// Header file for network requests
#import <AFNetworking.h>
@interface ViewController ()
{
  // Boolean value for network monitoring judgment
  BOOL isOpen;
}
// Session object used for network requests
@property (nonatomic, strong) AFHTTPSessionManager *session;
@end
@implementation ViewController
- (void)viewDidLoad {
  [super viewDidLoad];
  // Initialize the Session object
  self.session = [AFHTTPSessionManager manager];
  // Set the supported data types when the request interface returns
  self.session.responseSerializer.acceptableContentTypes = [NSSet setWithObjects:@"application/json", @"text/json", @"text/javascript",@"application/x-json",@"text/html", nil];
}
#pragma mark - Response method for network monitoring button
- (IBAction)NetworkmonitoringAction:(id)sender {
  if (!isOpen) {
    //Open network monitoring
    [[AFNetworkReachabilityManager sharedManager] startMonitoring];
    isOpen = YES;
  }
    // Close network monitoring
    [[AFNetworkReachabilityManager sharedManager] stopMonitoring];
    isOpen = NO;
  }
  // Next, it will judge whether the current status is WiFi or3g status, network unavailable status
  [[AFNetworkReachabilityManager sharedManager] setReachabilityStatusChangeBlock:^(AFNetworkReachabilityStatus status) {
    switch (status) {
      case AFNetworkReachabilityStatusUnknown:
        NSLog(@"Current network is in an unknown state");
        break;
      case AFNetworkReachabilityStatusNotReachable:
        NSLog(@"Current network is not connected");
        break;
