iOS網絡編程(7) 第三方開源庫----->AFNetworking · iOS 高級

AFNetworking是一個為?iOS?和?Mac OSX?制作的令人愉快的網絡庫，它建立在URL?裝載系統框架的頂層，內置在Cocoa里，擴展了強有力的高級網絡抽象。它的模塊架構被良好的設計，擁有豐富的功能，因此，使用起來，必定賞心悅目。 ? ? ? ?@原文鏈接https://github.com/AFNetworking/AFNetworking,我在此基礎上了點配置修改 ? ? ? ?@介紹　　1.支持HTTP請求和基于REST的網絡服務(包括GET、POST、 PUT、DELETE等) 　　2.支持ARC 　　3.要求iOS 5.0及以上版本　　4.UIKit擴展 ? ? ? ?@配置 ? ? ? ?1.下載[AFNetworking](http://afnetworking.com/),將2個文件夾:AFNetworking和UIKit+AFNetworking拖入工程 ? ? ? ?2.導入以下庫文件:CFNetwork、Security、SystemConfiguration、MobileCoreServices ? ? ? ?3.如果你以前用的是1.0版本,那么[AFNetworking 2.0 Migration Guide](https://github.com/AFNetworking/AFNetworking/wiki/AFNetworking-2.0-Migration-Guide)能幫助你 ? ? ? ?4.如果你是用CocoaPods配置的,那么 ? ? ? ? ? ?platform:ios,'7.0' ? ? ? ? ? ?pod"AFNetworking","~>2.0" ? ? ? ? ? ?@使用 ? ? ? ? ? ?1.HTTP請求操作 ? ? ? ? ? ?AFHTTPRequestOperationManager封裝的共同模式與web應用程序通過HTTP通信,包括創建請求,響應序列化,網絡可達性監控、運營管理和安全,以及請求。 ? ? ? ? ? ?GET請求 ~~~ 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請求 ~~~ 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請求(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詳細見[網絡編程(6)](http://blog.csdn.net/hmt20130412/article/details/29412349)) ? ? ? ? ? ? ?創建和管理制定的NSURLSession對象NSURLSessionConfiguration對象必須實現, , , 協議 ? ? ? ? ? ? ? 創建一個下載任務 ~~~ 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]; ~~~ ? ? ? ??? ? ? ?創建一個上傳任務 ~~~ 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]; ~~~ ? ? ? ? ? ? ?創建一個帶多表,進度的上傳任務 ~~~ 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]; ~~~ ? ? ? ? ? ? ? 創建一個數據流Data任務 ~~~ 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.網絡監測(一般會用另一個網絡監測類,Reachability,還有JSON解析方法,反正我也一般不用,自行腦補) ? ? ? ? ? ? ? ? AFNetworkReachabilityManager監控網絡領域的可達性,WWAN地址和WiFi接口. ? ? ? ? ? ? ? ?當前網絡狀態 ~~~ [[AFNetworkReachabilityManager sharedManager] setReachabilityStatusChangeBlock:^(AFNetworkReachabilityStatus status) { NSLog(@"Reachability: %@", AFStringFromNetworkReachabilityStatus(status)); }]; ~~~ ? ? ? ? ? ? ?

AFHTTPRequestOperation是使用HTTP或HTTPS協議的AFURLConnectionOperation的子類。它封裝的獲取后的HTTP狀態和類型將決定請求的成功與否。雖然AFHTTPRequestOperationManager通常是最好的去請求的方式，但是AFHTTPRequestOpersion也能夠單獨使用。 ? ? ? ? ? ? ? ? ?GET請求 ~~~ 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]; ~~~ ? ? ? ? ? ? ? ?批量多請求 ~~~ 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]; ~~~ ? ? ? ? ? ? ? ? ? @其他資料 ? ? ? ? ? ? ? ? ?1.[官網](http://afnetworking.com/) ? ? ? ? ? ? ? ? ?2.[英文文檔](http://cocoadocs.org/docsets/AFNetworking/2.0.3/)
