四.AFNetworking请求 get与post

对服务器返回数据的解析
1.AFN可以自动对服务器返回的数据进行解析* 默认将服务器返回的数据当做JSON来解析
2.设置对服务器返回数据的解析方式

1> 当做是JSON来解析（默认做法）
*mgr.responseSerializer = [AFJSONResponseSerializer serializer];
*responseObject
的类型是NSDictionary
或者NSArray

2> 当做是xml来解析
*mgr.responseSerializer = [AFXMLParserResponseSerializer serializer];
*responseObject
的类型是NSXMLParser

3> 直接返回data* 意思是：告诉AFN不要去解析服务器返回的数据，保持原来的data即可
*mgr.responseSerializer = [AFHTTPResponseSerializer serializer];

AFNetworking请求 get与post

1.  AFHTTPRequestOperationManager * mager=[AFHTTPRequestOperationManager manager];
    mager.responseSerializer.acceptableContentTypes = [NSSet setWithObject:@"text/html”];

//参数
    NSMutableDictionary *params = [NSMutableDictionary dictionary];
    NSUserDefaults *userDefaultes = [NSUserDefaults standardUserDefaults];
    params[@"uid"]=[userDefaultes stringForKey:@"uid"];
    params[@"page"]=[NSString stringWithFormat:@"%d",_page];
    params[@"kw"]=searchString;

//get方法
    [mager GET:[NSString stringWithFormat:@"%@/DoctorIndex2/searchHzDoctor",API] parameters:params success:^(AFHTTPRequestOperation *operation, id responseObject) {
    NSMutableArray *dataArray=responseObject[@"data"];
        int code=[responseObject[@"code"]intValue];
        if(code==1)
        {
            for(int i=0;i<dataArray.count;i++)
            {
                NSDictionary *dic=dataArray[i];
                DoctorModel *model=[DoctorModel new];
                model.docterID=[NSString stringWithFormat:@"%d",[dic[@"id"]intValue]];
                model.avatar=dic[@"avatar"];
                [_searchArray addObject:model];
            }

        }else//当code是0或者-1
        {     
           
        }

        [self.tableView reloadData];

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

    }];
//post方法
 AFHTTPRequestOperationManager * mager=[AFHTTPRequestOperationManager manager];
 mager.responseSerializer.acceptableContentTypes = [NSSet setWithObject:@"text/html"];
 NSMutableDictionary *params = [NSMutableDictionary dictionary];
            params[@"openid"]=snsAccount.usid;
            params[@"sdk_type"]=@"0";
[mager GET:[NSString stringWithFormat:@"%@/UserAuths/query",API] parameters:params success:^(AFHTTPRequestOperation *operation, id responseObject) {
                NSLog(@"微信提交openid返回的数据:%@",responseObject);

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