get请求方式
//创建AFHTTPSessionManager对象
AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
//响应体序列化对象
// AFHTTPResponseSerializer *noSerializer = [AFHTTPResponseSerializer serializer]; //二进制的形式 (不解析)
// AFJSONResponseSerializer *jsonSerializer = [AFJSONResponseSerializer serializer]; //json的格式 (默认)

//(2)请求体序列化对象
//请求体中的数据格式

//设置请求体序列化

//设置get请求方式

post请求方式一
//创建一个参数字典

post请求方式二
//设置请求路径
NSString *url = @"https://upload.api.weibo.com/2/statuses/upload.json";
//设置参数字典

//1创建AFHTTPSessionManager对象
AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
//2创建post申请方式
[manager POST:url parameters:params constructingBodyWithBlock:^(id<AFMultipartFormData> _Nonnull formData) {
//fromData：生成请求体的data对象
//复杂数据 追加到formData中
//获得图片路径
NSString *path = [[NSBundle mainBundle]pathForResource:@"1.jpeg" ofType:nil];
//获得图片data
NSData *picData = [NSData dataWithContentsOfFile:path];
//把图片数据追加到formData中
