iOS AFNetworking(网络框架)
AFNetworking NSURLConnection ---导入头文件"AFHTTPRequestOperationManager.h" 1. 发送GET请求 //发送get请求 - (void)get { [[AFHTTPRequestOperationManager manager] GET:@"http://127.0.0.1/demo.json" parameters:nil success:^(AFHTTPRequestOperation * _Nonnull operation, id _Nonnull responseObject) { NSLog(@"%@",responseObject); NSLog(@"%@",[responseObject class]); } failure:^(AFHTTPRequestOperation * _Nullable operation, NSError * _Nonnull error) { NSLog(@"%@",error); }]; } 2. 发送GET请求--带参数 //发送get请求，传参数 - (void)get { [[AFHTTPRequestOperationManager manager] GET:@"http://127.0.0.1/php/login.php" parameters:@{@"username":@"abc",@"password":@"123"} success:^(AFHTTPRequestOperation * _Nonnull operation, id _Nonnull responseObject) { NSLog(@"%@",responseObject); } failure:^(AFHTTPRequestOperation * _Nullable operation, NSError * _Nonnull error) { NSLog(@"%@",error); }]; } 3. 发送POST请求 //演示post请求 - (void)post { [[AFHTTPRequestOperationManager manager] POST:@"http://127.0.0.1/php/login.php" parameters:@{@"username":@"abcd",@"password":@"lalala"} success:^(AFHTTPRequestOperation * _Nonnull operation, id _Nonnull responseObject) { NSLog(@"%@",responseObject); } failure:^(AFHTTPRequestOperation * _Nullable operation, NSError * _Nonnull error) { NSLog(@"%@",error); }]; } 4. 上传文件 - (void)post { //获取要上传文件的路径 NSURL *url1 = [[NSBundle mainBundle] URLForResource:@"06.jpg" withExtension:nil]; NSURL *url2 = [[NSBundle mainBundle] URLForResource:@"01.jpg" withExtension:nil]; [[AFHTTPRequestOperationManager manager] POST:@"http://127.0.0.1/php/upload/upload-m.php" parameters:@{@"username":@"zhangsan"} constructingBodyWithBlock:^(id<AFMultipartFormData> _Nonnull formData) { //上传文件 [formData appendPartWithFileURL:url1 name:@"userfile[]" error:nil]; [formData appendPartWithFileURL:url2 name:@"userfile[]" error:nil]; } success:^(AFHTTPRequestOperation * _Nonnull operation, id _Nonnull responseObject) { NSLog(@"%@",responseObject); } failure:^(AFHTTPRequestOperation * _Nullable operation, NSError * _Nonnull error) { NSLog(@"%@",error); }]; } NSURLSession ---导入头文件"AFHTTPSessionManager.h" 1. 发送GET请求 - (void)get { [[AFHTTPSessionManager manager] GET:@"http://127.0.0.1/demo.json" parameters:nil success:^(NSURLSessionDataTask * _Nonnull task, id _Nonnull responseObject) { NSLog(@"%@",responseObject); } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) { NSLog(@"%@",error); }]; } 2. 下载任务 - (void)download { NSURL *url = [NSURL URLWithString:@"http://127.0.0.1/abc.hm"]; NSURLRequest *request = [NSURLRequest requestWithURL:url]; //进度 NSProgress *progress = nil; [[[AFHTTPSessionManager manager] downloadTaskWithRequest:request progress:&progress destination:^NSURL * _Nonnull(NSURL * _Nonnull targetPath, NSURLResponse * _Nonnull response) { // NSLog(@"targetPath -- %@",targetPath); NSString *path = [[NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES) lastObject] stringByAppendingPathComponent:response.suggestedFilename]; // 本地文件的URL必须使用这种方式获取 NSURL *url = [[NSURL alloc] initFileURLWithPath:path]; //返回要保存文件的路径 return url; } completionHandler:^(NSURLResponse * _Nonnull response, NSURL * _Nullable filePath, NSError * _Nullable error) { NSLog(@"%@",filePath); }] resume]; //观察progress的某个属性fractionCompleted（进度）是否发生变化 //KVO [progress addObserver:self forKeyPath:@"fractionCompleted" options:NSKeyValueObservingOptionNew context:nil]; } - (void)observeValueForKeyPath:(NSString *)keyPath ofObject:(id)object change:(NSDictionary<NSString *,id> *)change context:(void *)context { if ([object isKindOfClass:[NSProgress class]]) { // NSLog(@"%@",change); NSProgress *progress = object; NSLog(@"%@",progress.localizedDescription); NSLog(@"%@",progress.localizedAdditionalDescription); NSLog(@"completedUnitCount : %zd",progress.completedUnitCount); NSLog(@"totalUnitCount : %zd",progress.totalUnitCount); NSLog(@"fractionCompleted : %f",progress.fractionCompleted); //回到主线程更新UI NSLog(@"%@",[NSThread currentThread]); } } 3. 获取网页数据--修改默认的序列化器 - (void)getBaidu { AFHTTPSessionManager *manager = [AFHTTPSessionManager manager]; //修改响应的序列化器 manager.responseSerializer = [AFHTTPResponseSerializer serializer]; [manager GET:@"http://www.baidu.com" parameters:nil success:^(NSURLSessionDataTask * _Nonnull task, id _Nonnull responseObject) { NSString *html = [[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding]; NSLog(@"%@",html); } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) { NSLog(@"%@",error); }]; } 4. 解析XML - (void)getXML { AFHTTPSessionManager *manager = [AFHTTPSessionManager manager]; // 设置序列号器为XML，也可修改为AFHTTPResponseSerializer，使用第三方框架解析二进制数据 manager.responseSerializer = [AFXMLParserResponseSerializer serializer]; [manager GET:@"http://127.0.0.1/videos.xml" parameters:nil success:^(NSURLSessionDataTask * _Nonnull task, NSXMLParser *responseObject) { //解析xml responseObject.delegate = self; [responseObject parse]; } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) { NSLog(@"%@",error); }]; } //NSXMLParser 的代理方法 - (void)parserDidStartDocument:(NSXMLParser *)parser { NSLog(@"1 开始解析"); } - (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName attributes:(NSDictionary<NSString *,NSString *> *)attributeDict { NSLog(@"2 开始节点 %@ %@",elementName,attributeDict); } - (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string { NSLog(@"3 节点之间的内容 %@",string); } - (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName { NSLog(@"4 结束节点 %@",elementName); } - (void)parserDidEndDocument:(NSXMLParser *)parser { NSLog(@"5 结束解析"); } - (void)parser:(NSXMLParser *)parser parseErrorOccurred:(NSError *)parseError { NSLog(@"6 错误"); }
