在.h声明方法
定义block回调
typedef void (^resultBlock)(id responseObject);//返回数据
-(void)updatePictureApi:(id)Api picArr:(NSArray*)picArr type:(NSString *)type withBlock:(resultBlock)block;
在类的.m
+(AFHTTPSessionManager*)getSession{
//网络请求初始化
AFHTTPSessionManager *sessionManager = [AFHTTPSessionManager manager];
[sessionManager.securityPolicy setAllowInvalidCertificates:YES];
sessionManager.requestSerializer.timeoutInterval = 10.f;//改成10s
sessionManager.responseSerializer = [AFJSONResponseSerializer serializer];//回复序列化
sessionManager.requestSerializer = [AFHTTPRequestSerializer serializer];
// sessionManager.requestSerializer.stringEncoding = NSUTF8StringEncoding;
sessionManager.responseSerializer.acceptableContentTypes = [NSSet setWithObjects:@"application/json",
@"text/html",
@"image/jpeg",
@"image/png",
@"application/octet-stream",
@"text/json",
@"text/javascript",
nil];
return sessionManager;
}
//上传图片-(void)updatePictureApi:(id)Api picArr:(NSArray*)picArr type:(NSString *)type withBlock:(resultBlock)block{ NSString *hostUrl; for(int i=0;i_Nonnull formData) {

下面就是控制器里面传参数，解析数据了
