Regex ViewState值不为'；无法从请求中提取

我需要登录到jsf页面。但是当我试图提取ViewState值时，它不起作用

ViewState输入字段如下所示：

<input type="hidden" name="javax.faces.ViewState" id="javax.faces.ViewState" value="-2660902297226015539:-7257444434252784696" autocomplete="off" />

POST data:
j_idt52=j_idt52&j_idt52%3Aj_idt53%3Aj_idt78%3AloginUsername%3AinputField=XXXXX&
j_idt52%3Aj_idt53%3Aj_idt78%3AloginPassword%3AinputSecretField=XXXXXX&
j_idt52%3Aj_idt53%3Aj_idt78%3AloginSend=Login&j_idt52%3Aj_idt53%
3Aj_idt78_active=0&javax.faces.ViewState=

 POST data:
 j_idt52=j_idt52&j_idt52%3Aj_idt53%3Aj_idt78%3AloginUsername%3AinputField=XXXXXX
 &j_idt52%3Aj_idt53%3Aj_idt78%3AloginPassword%3AinputSecretField=XXXXXX&
 j_idt52%3Aj_idt53%3Aj_idt78%3AloginSend=Login&j_idt52%3Aj_idt53%
 3Aj_idt78_active=0
 &javax.faces.ViewState=%24%7BViewState%7D

登录请求中的ViewState参数如下所示：

测试计划如下所示：

<input type="hidden" name="javax.faces.ViewState" id="javax.faces.ViewState" value="-2660902297226015539:-7257444434252784696" autocomplete="off" />

POST data:
j_idt52=j_idt52&j_idt52%3Aj_idt53%3Aj_idt78%3AloginUsername%3AinputField=XXXXX&
j_idt52%3Aj_idt53%3Aj_idt78%3AloginPassword%3AinputSecretField=XXXXXX&
j_idt52%3Aj_idt53%3Aj_idt78%3AloginSend=Login&j_idt52%3Aj_idt53%
3Aj_idt78_active=0&javax.faces.ViewState=

 POST data:
 j_idt52=j_idt52&j_idt52%3Aj_idt53%3Aj_idt78%3AloginUsername%3AinputField=XXXXXX
 &j_idt52%3Aj_idt53%3Aj_idt78%3AloginPassword%3AinputSecretField=XXXXXX&
 j_idt52%3Aj_idt53%3Aj_idt78%3AloginSend=Login&j_idt52%3Aj_idt53%
 3Aj_idt78_active=0
 &javax.faces.ViewState=%24%7BViewState%7D

但当我发送POST数据时，如下所示：

<input type="hidden" name="javax.faces.ViewState" id="javax.faces.ViewState" value="-2660902297226015539:-7257444434252784696" autocomplete="off" />

POST data:
j_idt52=j_idt52&j_idt52%3Aj_idt53%3Aj_idt78%3AloginUsername%3AinputField=XXXXX&
j_idt52%3Aj_idt53%3Aj_idt78%3AloginPassword%3AinputSecretField=XXXXXX&
j_idt52%3Aj_idt53%3Aj_idt78%3AloginSend=Login&j_idt52%3Aj_idt53%
3Aj_idt78_active=0&javax.faces.ViewState=

 POST data:
 j_idt52=j_idt52&j_idt52%3Aj_idt53%3Aj_idt78%3AloginUsername%3AinputField=XXXXXX
 &j_idt52%3Aj_idt53%3Aj_idt78%3AloginPassword%3AinputSecretField=XXXXXX&
 j_idt52%3Aj_idt53%3Aj_idt78%3AloginSend=Login&j_idt52%3Aj_idt53%
 3Aj_idt78_active=0
 &javax.faces.ViewState=%24%7BViewState%7D

它不插入视图状态。

我还尝试将正则表达式Exctrator与以下表达式一起使用：

<input type="hidden" name="javax\.faces\.ViewState" id="javax\.faces\.ViewState" value="(\w+?)"

编码参数为：

javax.faces.ViewState=${ViewState}

---

问题在哪里？

我找到了解决办法。我必须将XPath提取器添加到HTTP请求中，这与测试计划屏幕截图中的情况不同。

当我为两个后处理器添加默认值时，它表示ViewState值没有被覆盖
