- AFNetworking是一个为 iOS 和 Mac OSX 制作的令人愉快的网络库，它建立在URL 装载系统框架的顶层，内置在Cocoa里，扩展了强有力的高级网络抽象。它的模块架构被良好的设计，拥有丰富的功能，因此，使用起来，必定赏心悦目。
@介绍
1.支持HTTP请求和基于REST的网络服务(包括GET、POST、 PUT、DELETE等) - 2.支持ARC
- 3.要求iOS 5.0及以上版本
- 4.UIKit扩展
@配置
1.下载AFNetworking,将2个文件夹:AFNetworking和UIKit+AFNetworking拖入工程
2.导入以下库文件:CFNetwork、Security、SystemConfiguration、MobileCoreServices
3.如果你以前用的是1.0版本,那么AFNetworking 2.0 Migration Guide能帮助你
4.如果你是用CocoaPods配置的,那么
platform:ios,‘7.0‘
pod"AFNetworking","~>2.0"
@使用
1.HTTP请求操作
AFHTTPRequestOperationManager封装的共同模式与web应用程序通过HTTP通信,包括创建请求,响应序列化,网络可达性监控、运营管理和安全,以及请求。
*GET请求
view source
print
?1.
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];2.
[manager GET:@"http://example.com/resources.json" parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) {3.
NSLog(@"JSON: %@", responseObject);4.
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {5.
NSLog(@"Error: %@", error);6.
}];*POST请求
view source
print
?1.
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];2.
NSDictionary *parameters = @{@"foo": @"bar"};3.
[manager POST:@"http://example.com/resources.json" parameters:parameters success:^(AFHTTPRequestOperation *operation, id responseObject) {4.
NSLog(@"JSON: %@", responseObject);5.
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {6.
NSLog(@"Error: %@", error);7.
}];*POST请求(多表)
view source
print
?01.
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];02.
NSDictionary *parameters = @{@"foo": @"bar"};03.
NSURL *filePath = [NSURL fileURLWithPath:@"file://path/to/image.png"];04.
[manager POST:@"http://example.com/resources.json" parameters:parameters constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {05.
[formData appendPartWithFileURL:filePath name:@"image" error:nil];06.
} success:^(AFHTTPRequestOperation *operation, id responseObject) {07.
NSLog(@"Success: %@", responseObject);08.
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {09.
NSLog(@"Error: %@", error);10.
}];2.AFURLSessionManager(NSURLSession详细见网络编程(6))
创建和管理制定的NSURLSession对象NSURLSessionConfiguration对象必须实现<NSURLSessionTaskDelegate>, <NSURLSessionDataDelegate>, <NSURLSessionDownloadDelegate>, <NSURLSessionDelegate>协议
*创建一个下载任务
view source
print
?01.
NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];02.
AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:configuration];03.
04.
NSURL *URL = [NSURL URLWithString:@"http://example.com/download.zip"];05.
NSURLRequest *request = [NSURLRequest requestWithURL:URL];06.
07.
NSURLSessionDownloadTask *downloadTask = [manager downloadTaskWithRequest:request progress:nil destination:^NSURL *(NSURL *targetPath, NSURLResponse *response) {08.
NSURL *documentsDirectoryURL = [[NSFileManager defaultManager] URLForDirectory:NSDocumentDirectory inDomain:NSUserDomainMask appropriateForURL:nil create:NO error:nil];09.
return [documentsDirectoryURL URLByAppendingPathComponent:[response suggestedFilename]];10.
} completionHandler:^(NSURLResponse *response, NSURL *filePath, NSError *error) {11.
NSLog(@"File downloaded to: %@", filePath);12.
}];13.
[downloadTask resume];*创建一个上传任务
view source
print
?01.
NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];02.
AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:configuration];03.
04.
NSURL *URL = [NSURL URLWithString:@"http://example.com/upload"];05.
NSURLRequest *request = [NSURLRequest requestWithURL:URL];06.
07.
NSURL *filePath = [NSURL fileURLWithPath:@"file://path/to/image.png"];08.
NSURLSessionUploadTask *uploadTask = [manager uploadTaskWithRequest:request fromFile:filePath progress:nil completionHandler:^(NSURLResponse *response, id responseObject, NSError *error) {09.
if (error) {10.
NSLog(@"Error: %@", error);11.
} else {12.
NSLog(@"Success: %@ %@", response, responseObject);13.
}14.
}];15.
[uploadTask resume];*创建一个带多表,进度的上传任务
view source
print
?01.
NSMutableURLRequest *request = [[AFHTTPRequestSerializer serializer] multipartFormRequestWithMethod:@"POST" URLString:@"http://example.com/upload" parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {02.
[formData appendPartWithFileURL:[NSURL fileURLWithPath:@"file://path/to/image.jpg"] name:@"file" fileName:@"filename.jpg" mimeType:@"image/jpeg" error:nil];03.
} error:nil];04.
05.
AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];06.
NSProgress *progress = nil;07.
08.
NSURLSessionUploadTask *uploadTask = [manager uploadTaskWithStreamedRequest:request progress:&progress completionHandler:^(NSURLResponse *response, id responseObject, NSError *error) {09.
if (error) {10.
NSLog(@"Error: %@", error);11.
} else {12.
NSLog(@"%@ %@", response, responseObject);13.
}14.
}];15.
16.
[uploadTask resume];*创建一个数据流Data任务
view source
print
?01.
NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];02.
AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:configuration];03.
04.
NSURL *URL = [NSURL URLWithString:@"http://example.com/upload"];05.
NSURLRequest *request = [NSURLRequest requestWithURL:URL];06.
07.
NSURLSessionDataTask *dataTask = [manager dataTaskWithRequest:request completionHandler:^(NSURLResponse *response, id responseObject, NSError *error) {08.
if (error) {09.
NSLog(@"Error: %@", error);10.
} else {11.
NSLog(@"%@ %@", response, responseObject);12.
}13.
}];14.
[dataTask resume];3.网络监测(一般会用另一个网络监测类,Reachability,还有JSON解析方法,反正我也一般不用,自行脑补)
AFNetworkReachabilityManager监控网络领域的可达性,WWAN地址和WiFi接口.
*当前网络状态
view source
print
?1.
[[AFNetworkReachabilityManager sharedManager] setReachabilityStatusChangeBlock:^(AFNetworkReachabilityStatus status) {2.
NSLog(@"Reachability: %@", AFStringFromNetworkReachabilityStatus(status));3.
}]; - *HTTP Manager 可达性
view source
print
?01.
NSURL *baseURL = [NSURL URLWithString:@"http://example.com/"];02.
AFHTTPRequestOperationManager *manager = [[AFHTTPRequestOperationManager alloc] initWithBaseURL:baseURL];03.
04.
NSOperationQueue *operationQueue = manager.operationQueue;05.
[manager.reachabilityManager setReachabilityStatusChangeBlock:^(AFNetworkReachabilityStatus status) {06.
switch (status) {07.
case AFNetworkReachabilityStatusReachableViaWWAN:08.
case AFNetworkReachabilityStatusReachableViaWiFi:09.
[operationQueue setSuspended:NO];10.
break;11.
case AFNetworkReachabilityStatusNotReachable:12.
default:13.
[operationQueue setSuspended:YES];14.
break;15.
}16.
}];4.AFHTTPRequestOperation
AFHTTPRequestOperation是使用HTTP或HTTPS协议的AFURLConnectionOperation的子类。
它封装的获取后的HTTP状态和类型将决定请求的成功与否。虽然AFHTTPRequestOperationManager通常是最好的去请求的方式，但是AFHTTPRequestOpersion也能够单独使用。
*GET请求
view source
print
?01.
NSURL *URL = [NSURL URLWithString:@"http://example.com/resources/123.json"];02.
NSURLRequest *request = [NSURLRequest requestWithURL:URL];03.
AFHTTPRequestOperation *op = [[AFHTTPRequestOperation alloc] initWithRequest:request];04.
op.responseSerializer = [AFJSONResponseSerializer serializer];05.
[op setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {06.
NSLog(@"JSON: %@", responseObject);07.
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {08.
NSLog(@"Error: %@", error);09.
}];10.
[[NSOperationQueue mainQueue] addOperation:op]; - *批量多请求
view source
print
?01.
NSMutableArray *mutableOperations = [NSMutableArray array];02.
for (NSURL *fileURL in filesToUpload) {03.
NSURLRequest *request = [[AFHTTPRequestSerializer serializer] multipartFormRequestWithMethod:@"POST" URLString:@"http://example.com/upload" parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {04.
[formData appendPartWithFileURL:fileURL name:@"images[]" error:nil];05.
}];06.
07.
AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request];08.
09.
[mutableOperations addObject:operation];10.
}11.
12.
NSArray *operations = [AFURLConnectionOperation batchOfRequestOperations:@[...] progressBlock:^(NSUInteger numberOfFinishedOperations, NSUInteger totalNumberOfOperations) {13.
NSLog(@"%lu of %lu complete", numberOfFinishedOperations, totalNumberOfOperations);14.
} completionBlock:^(NSArray *operations) {15.
NSLog(@"All operations in batch complete");16.
}];17.
[[NSOperationQueue mainQueue] addOperations:operations waitUntilFinished:NO]; - @其他资料
