关于修改AFN源码:通常序列化时做对text/plan等的支持时,可以一劳永逸的修改源代码,在acceptableContentTypes中修改即可。
AFN进行GET、POST登录:
[objc] view plaincopy#pragma mark - get/post登录 - (void)getLogin { //1.管理器 AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager]; //2.设置登录参数 NSDictionary *dict = @{ @"username":@"xn", @"passWord":@"123" }; //3.请求 [manager GET:@"http://localhost/login.php" parameters:dict success: ^(AFHTTPRequestOperation *operation, id responSEObject) { NSLog(@"GET --> %@, %@", responseObject, [NSThread currentThread]); //自动返回主线程 } failure: ^(AFHTTPRequestOperation *operation, NSError *error) { NSLog(@"%@", error); }]; } /** * 和上面的GET用法完全一样, 只有一个POST参数不一样 */ - (void)postLogin { //1.管理器 AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager]; //2.设置登录参数 NSDictionary *dict = @{ @"username":@"xn", @"password":@"123" }; //3.请求 [manager POST:@"http://localhost/login.php" parameters:dict success: ^(AFHTTPRequestOperation *operation, id responseObject) { NSLog(@"POST --> %@, %@", responseObject, [NSThread currentThread]); //自动返回主线程 } failure: ^(AFHTTPRequestOperation *operation, NSError *error) { NSLog(@"%@", error); }]; } AFN进行网络数据解析,获取Plist,JSON,XML(AFN不支持自动解析XML,有专门的框架去做,如SAX,PULL,KissXML等)[objc] view plaincopy#pragma mark - get 数据解析 - (void)getJSON { //1.请求管理器 AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager]; //2.发起请求 [manager GET:@"http://localhost/videos.json" parameters:nil success: ^(AFHTTPRequestOperation *operation, id responseObject) { NSLog(@"%@", responseObject); } failure: ^(AFHTTPRequestOperation *operation, NSError *error) { NSLog(@"%@", error); }]; } /** * 不支持XML数据解析 */ - (void)getXML { //1.管理器 AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager]; //2.设置返回数据类型 manager.responseSerializer = [AFXMLParserResponseSerializer serializer]; //先实例化一下 //3.发起请求 [manager GET:@"http://localhost/videos.xml" parameters:nil success: ^(AFHTTPRequestOperation *operation, id responseObject) { NSLog(@"%@", responseObject); } failure: ^(AFHTTPRequestOperation *operation, NSError *error) { NSLog(@"%@", error); }]; } - (void)getPlist { //1.管理器 AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager]; //2.设置response类型 manager.responseSerializer = [AFPropertyListResponseSerializer serializer]; //是Response, 别写成request了. 修改为plist类型. manager.responseSerializer.acceptableContentTypes = [NSSet setWithObject:@"text/plain"]; //这个可以直接往框架里面修改. //3.请求 [manager GET:@"http://localhost/videos.plist" parameters:nil success: ^(AFHTTPRequestOperation *operation, id responseObject) { NSLog(@"%@", responseObject); } failure: ^(AFHTTPRequestOperation *operation, NSError *error) { NSLog(@"%@", error); }]; } 用AFN来POST JSON数据,上传、下载等。(上传、下载主页说明上有https://github.com/AFNetworking/AFNetworking)[objc] view plaincopy#pragma mark - post json数据与上传文件等 - (void)postJSON { //1.管理器 AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager]; //2.设定类型. (这里要设置request-response的类型) manager.requestSerializer = [AFJSONRequestSerializer serializer]; manager.responseSerializer = [AFHTTPResponseSerializer serializer]; //这个决定了下面responseObject返回的类型 // manager.responseSerializer = [AFJSONResponseSerializer serializer]; // manager.responseSerializer.acceptableContentTypes = [NSSet setWithObject:@"text/plain"]; //2.设置登录参数 NSDictionary *dict = @{ @"username":@"xn", @"password":@"123" }; //3.发送请求 [manager POST:@"http://localhost/postjson.php" parameters:dict success: ^(AFHTTPRequestOperation *operation, id responseObject) { // NSLog(@"postjson--> %@", responseObject); //这样显示JSON的话需要设置text/plain NSString *result = [[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding]; NSLog(@"%@",result); } failure: ^(AFHTTPRequestOperation *operation, NSError *error) { NSLog(@"%@", error); }]; } 转载自:http://blog.csdn.net/xn4545945新闻热点
