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();
- }
- }];
- }
