1.GET Request
AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
[manager GET:@"http://example.com/resources.json" parameters:nil progress:^(NSProgress * _Nonnull downloadProgress){
}success:^(NSURLSessionDataTask * _Nonnull task, id _Nullable responseObject){
}failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error){
}];
2.POST URL-Form-Encoded Request
AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
NSDictionary *parameters = @{@"key": @"value"};
[manager POST:@"http://example.com/resources.json" parameters:parameters progress:^(NSProgress * _Nonnull uploadProgress) {
} success:^(NSURLSessionDataTask * _Nonnull task,id_Nullable responseObject) {
} failure:^(NSURLSessionDataTask * _Nullable task,NSError * _Nonnull error) {
}];
3.Download
NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];
AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:configuration];
NSURL *URL = [NSURL URLWithString:@"http://example.com/download.zip"];
NSURLRequest *request = [NSURLRequest requestWithURL:URL];
NSURLSessionDownloadTask *downloadTask = [manager downloadTaskWithRequest:request progress:nil destination:^NSURL *(NSURL *targetPath, NSURLResponse *response) {
NSURL *documentsDirectoryURL = [[NSFileManager defaultManager] URLForDirectory:NSDocumentDirectory inDomain:NSUserDomainMask appropriateForURL:nil create:NO error:nil];
return [documentsDirectoryURL URLByAppendingPathComponent:[response suggestedFilename]];
} completionHandler:^(NSURLResponse *response, NSURL *filePath, NSError *error) {
NSLog(@"File downloaded to: %@", filePath);
}];
[downloadTask resume];
4.Upload
NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];
AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:configuration];
NSURL *URL = [NSURL URLWithString:@"http://example.com/upload"];
NSURLRequest *request = [NSURLRequest requestWithURL:URL];
NSURL *filePath = [NSURL fileURLWithPath:@"file://path/to/image.png"];
NSURLSessionUploadTask *uploadTask = [manager uploadTaskWithRequest:request fromFile:filePath progress:nil completionHandler:^(NSURLResponse *response,id responseObject, NSError *error) {
if(error) {
NSLog(@"Error: %@", error);
}else{
NSLog(@"Success: %@ %@", response, responseObject);
}
}];
[uploadTask resume];
5.Creating an Upload Task for a Multi-Part Request, with Progress
NSMutableURLRequest *request = [[AFHTTPRequestSerializer serializer] multipartFormRequestWithMethod:@"POST" URLString:@"http://example.com/upload" parameters:nil constructingBodyWithBlock:^(id formData) {
[formData appendPartWithFileURL:[NSURL fileURLWithPath:@"file://path/to/image.jpg"] name:@"file" fileName:@"filename.jpg" mimeType:@"image/jpeg" error:nil];
} error:nil];
AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];
NSURLSessionUploadTask *uploadTask;
uploadTask = [manager uploadTaskWithStreamedRequest:request progress:^(NSProgress *_Nonnull uploadProgress) {
// This is not called back on the main queue.
// You are responsible for dispatching to the main queue for UI updates
dispatch_async(dispatch_get_main_queue(), ^{
//Update the progress view
[progressView setProgress:uploadProgress.fractionCompleted];
});
}
completionHandler:^(NSURLResponse *_Nonnull response,id_Nullable responseObject, NSError *_Nullable error) {
if(error) {
NSLog(@"Error: %@", error);
}else{
NSLog(@"%@ %@", response, responseObject);
}
}];
[uploadTask resume];
