关于 AFNetworking（3.0）的问题

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];
