Encapsulation of a network request data Class Based on AFNetWorking and afnetworking

Encapsulation of a network request data Class Based on AFNetWorking and afnetworking

1. Create a new class that inherits from the NSObject class. In the. h file

# Import "AFHTTPRequestOperationManager. h"

// Define two blocks to receive successful and failed requests

Typedef void (^ DownLoadFinishedBlock) (id responseObj );

Typedef void (^ DownLoadFialedBlock) (NSError * error );

 

@ Interface NetManager: NSObject

 

// Get Request Method Encapsulation

+ (Void) doGetWithUrlStr :( NSString *) urlString contentType :( NSString *) type finished :( DownLoadFinishedBlock) finished failure :( DownLoadFialedBlock) fialed;

// Method encapsulation of Post requests

+ (Void) doPostWithUrlStr :( NSString *) urlString parameters :( NSDictionary *) dic contentType :( NSString *) type finished :( DownLoadFinishedBlock) finished failure :( DownLoadFialedBlock) fialed;

 

 

2. The following is the implementation of the encapsulation method:

# Import "NetManager. h"

 

@ Implementation NetManager

 

// Get Request Method

+ (Void) doGetWithUrlStr :( NSString *) urlString contentType :( NSString *) type finished :( DownLoadFinishedBlock) finished failure :( DownLoadFialedBlock) fialed {

 

// Create a manager object

AFHTTPRequestOperationManager * manager = [AFHTTPRequestOperationManager];

// Set the request data type

Manager. responseSerializer. acceptableContentTypes = [NSSet setWithObjects: type, nil];

[Manager GET: urlString parameters: nil success: ^ (AFHTTPRequestOperation * operation, id responseObject ){

// The request is successful.

Finished (responseObject );

} Failure: ^ (AFHTTPRequestOperation * operation, NSError * error ){

// Request failed

Fialed (error );

}];

}

 

// Post Request Method

// Description: parameters: parameter, which is the parameter that needs to be sent to the backend server when a post request is used. Here we should encapsulate the data in a dictionary type, then pass the dictionary as a parameter.

 

+ (Void) doPostWithUrlStr :( NSString *) urlString parameters :( NSDictionary *) dic contentType :( NSString *) type finished :( DownLoadFinishedBlock) finished failure :( DownLoadFialedBlock) fialed

{

// Create a manager object

AFHTTPRequestOperationManager * manager = [AFHTTPRequestOperationManager];

// Set the request data type

Manager. responseSerializer = [AFHTTPResponseSerializer serializer];

Manager. responseSerializer. acceptableContentTypes = [NSSet setWithObjects: type, nil];

[Manager POST: urlString parameters: dic success: ^ (AFHTTPRequestOperation * operation, id responseObject ){

Finished (responseObject );

} Failure: ^ (AFHTTPRequestOperation * operation, NSError * error ){

Fialed (error );

}];

}
