但是还是有很多网站是使用的addslashes()函数进行过滤,我们不可能把所有的addslashes()函数都换成mysql_real_escape_string()。 所以防止宽字节注入的另一个方法就是将 character_set_client 设置为binary(二进制)。需要在所有的sql语句前指定连接的形式是binary二进制: 代码语言:javascript 代码运行次数:0 运行 AI...
宽字节注入发生的位置就是PHP发送请求到MYSQL时字符集使用character_set_client设置值进行了一次编码,然后服务器会根据character_set_connection把请求进行转码,从character_set_client转成character_set_connection,然后更新到数据库的时候,再转化成字段所对应的编码 ...
