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。
@原文链接https://github.com/AFNetworking/AFNetworking,我在此基础上了点配置修改
@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
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];[manager GET:@"http://example.com/resources.json" parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) { NSLog(@"JSON: %@", responseObject);} failure:^(AFHTTPRequestOperation *operation, NSError *error) { NSLog(@"Error: %@", error);}];
*POST请求
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];NSDictionary *parameters = @{@"foo": @"bar"};[manager POST:@"http://example.com/resources.json" parameters:parameters success:^(AFHTTPRequestOperation *operation, id responseObject) { NSLog(@"JSON: %@", responseObject);} failure:^(AFHTTPRequestOperation *operation, NSError *error) { NSLog(@"Error: %@", error);}];*POST请求(多表)
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];NSDictionary *parameters = @{@"foo": @"bar"};NSURL *filePath = [NSURL fileURLWithPath:@"file://path/to/image.png"];[manager POST:@"http://example.com/resources.json" parameters:parameters constructingBodyWithBlock:^(id<AFMultipartFormData> formData) { [formData appendPartWithFileURL:filePath name:@"image" error:nil];} success:^(AFHTTPRequestOperation *operation, id responseObject) { NSLog(@"Success: %@", responseObject);} failure:^(AFHTTPRequestOperation *operation, NSError *error) { NSLog(@"Error: %@", error);}];
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
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];*创建一个上传任务
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];*创建一个带多表,进度的上传任务
NSMutableURLRequest *request = [[AFHTTPRequestSerializer serializer] multipartFormRequestWithMethod:@"POST" URLString:@"http://example.com/upload" parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> 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]];NSProgress *progress = nil;NSURLSessionUploadTask *uploadTask = [manager uploadTaskWithStreamedRequest:request progress:&progress completionHandler:^(NSURLResponse *response, id responseObject, NSError *error) { if (error) { NSLog(@"Error: %@", error); } else { NSLog(@"%@ %@", response, responseObject); }}];[uploadTask resume];*创建一个数据流Data任务
NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:configuration];NSURL *URL = [NSURL URLWithString:@"http://example.com/upload"];NSURLRequest *request = [NSURLRequest requestWithURL:URL];NSURLSessionDataTask *dataTask = [manager dataTaskWithRequest:request completionHandler:^(NSURLResponse *response, id responseObject, NSError *error) { if (error) { NSLog(@"Error: %@", error); } else { NSLog(@"%@ %@", response, responseObject); }}];[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
[[AFNetworkReachabilityManager sharedManager] setReachabilityStatusChangeBlock:^(AFNetworkReachabilityStatus status) { NSLog(@"Reachability: %@", AFStringFromNetworkReachabilityStatus(status));}];
*HTTP Manager 可达性
NSURL *baseURL = [NSURL URLWithString:@"http://example.com/"];AFHTTPRequestOperationManager *manager = [[AFHTTPRequestOperationManager alloc] initWithBaseURL:baseURL];NSOperationQueue *operationQueue = manager.operationQueue;[manager.reachabilityManager setReachabilityStatusChangeBlock:^(AFNetworkReachabilityStatus status) { switch (status) { case AFNetworkReachabilityStatusReachableViaWWAN: case AFNetworkReachabilityStatusReachableViaWiFi: [operationQueue setSuspended:NO]; break; case AFNetworkReachabilityStatusNotReachable: default: [operationQueue setSuspended:YES]; break; }}];
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
NSURL *URL = [NSURL URLWithString:@"http://example.com/resources/123.json"];NSURLRequest *request = [NSURLRequest requestWithURL:URL];AFHTTPRequestOperation *op = [[AFHTTPRequestOperation alloc] initWithRequest:request];op.responseSerializer = [AFJSONResponseSerializer serializer];[op setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) { NSLog(@"JSON: %@", responseObject);} failure:^(AFHTTPRequestOperation *operation, NSError *error) { NSLog(@"Error: %@", error);}];[[NSOperationQueue mainQueue] addOperation:op];
*批量多请求
NSMutableArray *mutableOperations = [NSMutableArray array];for (NSURL *fileURL in filesToUpload) { NSURLRequest *request = [[AFHTTPRequestSerializer serializer] multipartFormRequestWithMethod:@"POST" URLString:@"http://example.com/upload" parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> formData) { [formData appendPartWithFileURL:fileURL name:@"images[]" error:nil]; }]; AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request]; [mutableOperations addObject:operation];}NSArray *operations = [AFURLConnectionOperation batchOfRequestOperations:@[...] progressBlock:^(NSUInteger numberOfFinishedOperations, NSUInteger totalNumberOfOperations) { NSLog(@"%lu of %lu complete", numberOfFinishedOperations, totalNumberOfOperations);} completionBlock:^(NSArray *operations) { NSLog(@"All operations in batch complete");}];[[NSOperationQueue mainQueue] addOperations:operations waitUntilFinished:NO];
