AFNetworking2.5使用
1.检测网络状态
+ (void)netWorkStatus { /** AFNetworkReachabilityStatusUnknown = -1, // 未知 AFNetworkReachabilityStatusNotReachable = 0, // 无连接 AFNetworkReachabilityStatusReachableViaWWAN = 1, // 3G 花钱 AFNetworkReachabilityStatusReachableViaWiFi = 2, // WiFi */ // 如果要检测网络状态的变化,必须用检测管理器的单例的startMonitoring [[AFNetworkReachabilityManager sharedManager] startMonitoring]; // 检测网络连接的单例,网络变化时的回调方法 [[AFNetworkReachabilityManager sharedManager] setReachabilityStatusChangeBlock:^(AFNetworkReachabilityStatus status) { NSLog(@"%ld", status); }]; }
2.JSON方式获取数据
+ (void)JSONDataWithUrl:(NSString *)url success:(void (^)(id json))success fail:(void (^)())fail; { AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager]; NSDictionary *dict = @{@"format": @"json"}; // 网络访问是异步的,回调是主线程的,因此程序员不用管在主线程更新UI的事情 [manager GET:url parameters:dict success:^(AFHTTPRequestOperation *operation, id responseObject) { if (success) { success(responseObject); } } failure:^(AFHTTPRequestOperation *operation, NSError *error) { NSLog(@"%@", error); if (fail) { fail(); } }]; }
3.xml方式获取数据
+ (void)XMLDataWithUrl:(NSString *)urlStr success:(void (^)(id xml))success fail:(void (^)())fail { AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager]; // 返回的数据格式是XML manager.responseSerializer = [AFXMLParserResponseSerializer serializer]; NSDictionary *dict = @{@"format": @"xml"}; // 网络访问是异步的,回调是主线程的,因此程序员不用管在主线程更新UI的事情 [manager GET:urlStr parameters:dict success:^(AFHTTPRequestOperation *operation, id responseObject) { if (success) { success(responseObject); } } failure:^(AFHTTPRequestOperation *operation, NSError *error) { NSLog(@"%@", error); if (fail) { fail(); } }]; }
4.post提交json数据
+ (void)postJSONWithUrl:(NSString *)urlStr parameters:(id)parameters success:(void (^)(id responseObject))success fail:(void (^)())fail { AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager]; // 设置请求格式 manager.requestSerializer = [AFJSONRequestSerializer serializer]; // 设置返回格式 manager.responseSerializer = [AFHTTPResponseSerializer serializer]; [manager POST:urlStr parameters:parameters success:^(AFHTTPRequestOperation *operation, id responseObject) { // NSString *result = [[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding]; if (success) { success(responseObject); } } failure:^(AFHTTPRequestOperation *operation, NSError *error) { NSLog(@"%@", error); if (fail) { fail(); } }]; }
5.下载文件
+ (void)sessionDownloadWithUrl:(NSString *)urlStr success:(void (^)(NSURL *fileURL))success fail:(void (^)())fail { NSURLSessionConfiguration *config = [NSURLSessionConfiguration defaultSessionConfiguration]; AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:config]; NSString *urlString = [urlStr stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]; NSURL *url = [NSURL URLWithString:urlString]; NSURLRequest *request = [NSURLRequest requestWithURL:url]; NSURLSessionDownloadTask *task = [manager downloadTaskWithRequest:request progress:nil destination:^NSURL *(NSURL *targetPath, NSURLResponse *response) { // 指定下载文件保存的路径 // NSLog(@"%@ %@", targetPath, response.suggestedFilename); // 将下载文件保存在缓存路径中 NSString *cacheDir = NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES)[0]; NSString *path = [cacheDir stringByAppendingPathComponent:response.suggestedFilename]; // URLWithString返回的是网络的URL,如果使用本地URL,需要注意 // NSURL *fileURL1 = [NSURL URLWithString:path]; NSURL *fileURL = [NSURL fileURLWithPath:path]; // NSLog(@"== %@ |||| %@", fileURL1, fileURL); if (success) { success(fileURL); } return fileURL; } completionHandler:^(NSURLResponse *response, NSURL *filePath, NSError *error) { NSLog(@"%@ %@", filePath, error); if (fail) { fail(); } }]; [task resume]; }
6.文件上传－自定义上传文件名
+ (void)postUploadWithUrl:(NSString *)urlStr fileUrl:(NSURL *)fileURL fileName:(NSString *)fileName fileType:(NSString *)fileTye success:(void (^)(id responseObject))success fail:(void (^)())fail { // 本地上传给服务器时,没有确定的URL,不好用MD5的方式处理 AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager]; manager.responseSerializer = [AFHTTPResponseSerializer serializer]; //@"http://localhost/demo/upload.php" [manager POST:urlStr parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> formData) { // NSURL *fileURL = [[NSBundle mainBundle] URLForResource:@"头像1.png" withExtension:nil]; // 要上传保存在服务器中的名称 // 使用时间来作为文件名 2014-04-30 14:20:57.png // 让不同的用户信息,保存在不同目录中 // NSDateFormatter *formatter = [[NSDateFormatter alloc] init]; // // 设置日期格式 // formatter.dateFormat = @"yyyy-MM-dd HH:mm:ss"; // NSString *fileName = [formatter stringFromDate:[NSDate date]]; //@"image/png" [formData appendPartWithFileURL:fileURL name:@"uploadFile" fileName:fileName mimeType:fileTye error:NULL]; } success:^(AFHTTPRequestOperation *operation, id responseObject) { if (success) { success(responseObject); } } failure:^(AFHTTPRequestOperation *operation, NSError *error) { if (fail) { fail(); } }]; }
7.文件上传－随机生成文件名
+ (void)postUploadWithUrl:(NSString *)urlStr fileUrl:(NSURL *)fileURL success:(void (^)(id responseObject))success fail:(void (^)())fail { AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager]; // AFHTTPResponseSerializer就是正常的HTTP请求响应结果:NSData // 当请求的返回数据不是JSON,XML,PList,UIImage之外,使用AFHTTPResponseSerializer // 例如返回一个html,text... // // 实际上就是AFN没有对响应数据做任何处理的情况 manager.responseSerializer = [AFHTTPResponseSerializer serializer]; // formData是遵守了AFMultipartFormData的对象 [manager POST:urlStr parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> formData) { // 将本地的文件上传至服务器 // NSURL *fileURL = [[NSBundle mainBundle] URLForResource:@"头像1.png" withExtension:nil]; [formData appendPartWithFileURL:fileURL name:@"uploadFile" error:NULL]; } success:^(AFHTTPRequestOperation *operation, id responseObject) { // NSString *result = [[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding]; // // NSLog(@"完成 %@", result); if (success) { success(responseObject); } } failure:^(AFHTTPRequestOperation *operation, NSError *error) { NSLog(@"错误 %@", error.localizedDescription); if (fail) { fail(); } }]; }
