contextPath:就是网站首页
str :是输入的密码的明文
url :contextPath+”抹掉的路径”,就是上面所说每次登陆之前去请求的页面,请求得到的就是modulus和exponent 值
RSAPUB_KEY就是利用RSAUtils.getKeyPair函数加密modulus和exponent得到的值
enpassword就是最后我们在 第一张图里burp 里抓到密码经过 js加密之后的值 :<input type="text" name="<em>modulus</em>" id="<em>modulus</em>"/>
exponent:<input type="text" name="exponent" id=" " style="display: none">{{ modulus }}
{{ exponent }}</p

一、函数适配器示例 - 函数适配器正常用法 1、modulus 函数对象 - 取模运算 在 <functional> 头文件 中 , 预定义了 modulus 函数对象 , 这是一个 二元函数对象 , 在该函数对象类中 , 重写了 函数调用操作符 函数 operator() , 该 预定义函数对象 代码如下 : // STRUCT TEMPLATE modulus template <class _ Ty = void> struct modulus { _CXX17_DEPRECATE_ADAPTOR_TYPEDEFS typedef _Ty first_argument_type; class _Ty = void> , _Ty 泛型的默认参数是 void , 即 如果 不指定 模板参数 , _Ty 泛型就是 void 类型 , 一般情况下使用 int 类型 进行取模运算 ; 在 modulus <int>(), 2))); 下面的代码中 , modulus 是一个二元函数对象 , 返回 0 或 1 可以当做 二元谓词 ; bind2nd(modulus<int>(), 2) 将 二元谓词 中的
(orientation=column); 创建子表: CREATE TABLE orders_p1 PARTITION OF orders_hash FOR VALUES WITH (MODULUS 4, REMAINDER 1); create table t_hash_partition_3 partition of t_hash_partition FOR VALUES WITH(MODULUS 4, REMAINDER 0); CREATE TABLE orders_mix_p2 PARTITION OF orders_mix FOR VALUES WITH (MODULUS 4, REMAINDER 1) with(orientation=column); CREATE TABLE orders_mix_p3 PARTITION OF orders_mix FOR VALUES WITH (MODULUS 4, REMAINDER 2); CREATE TABLE orders_mix_p4 PARTITION OF orders_mix FOR VALUES WITH (MODULUS 4, REMAINDER
3); 思路相同,需要指定configuration,并在进行hash分区时需要提供modulus。 tpart_hash ( a int primary key, b text) partition by hash (a) configuration (modulus (a) Indexes: "tpart_hash_pkey" PRIMARY KEY, btree (a) Partitions: tpart_hash_0 FOR VALUES WITH (modulus _2 FOR VALUES WITH (modulus 5, remainder 2), tpart_hash_3 FOR VALUES WITH (modulus 5, remainder 3), tpart_hash_4 FOR VALUES WITH (modulus 5, remainder 4) 真的很好,工作很棒,感谢所有相关人员,我希望接下来的步骤是:
