本文演示了如何使用AFNetworking进行POST请求，并处理返回的JSON数据。在按钮点击事件中，创建字典填充参数，通过AFHTTPRequestOperationManager发送POST请求。在成功回调中打印响应数据，在失败回调中打印错误信息。需要注意的是，必须正确设置responseSerializer以接受'application/json'类型的数据。

项目给出URL进行请求，先前一直用asi框架，但是一直请求失败，所以换了afnetworking框架

当点击页面button时进行网络请求现在这是一个demo测试

- (void)buttonAction {

NSMutableDictionary *dic = [[NSMutableDictionary alloc] init];

[dic setObject:@"liuyang" forKey:@"LoginName"];

[dic setObject:@"123456" forKey:@"Password"];

NSString *urlString = [NSString stringWithFormat:url];

// NSURL *url = [NSURL URLWithString:[urlString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];

// manager.responseSerializer = [AFJSONResponseSerializer serializer];

// manager.responseSerializer.acceptableContentTypes = [NSSet setWithObject:@"text/plain"];

manager.requestSerializer = [AFJSONRequestSerializer serializer];

[manager POST:urlString parameters:dic success:^(AFHTTPRequestOperation *operation, id responseObject) {

NSLog(@"success%@",responseObject);

} failure:^(AFHTTPRequestOperation *operation, NSError *error) {

NSLog(@"%@",error);

}];

}

// manager.responseSerializer = [AFJSONResponseSerializer serializer];

// manager.responseSerializer.acceptableContentTypes = [NSSet setWithObject:@"text/plain"];

// 前两行没有注释掉得时候一直发生错误
