Jmeter 参数未编码异常：java.net.URISyntaxException: Illegal character in query at index 172

最近在使用jmeter进行测试时，每次回放时，都回放失败，查看response data 提示：java.net.URISyntaxException: Illegal character in query at index 172 的异常信息。如下：

java.net.URISyntaxException: Illegal character in query at index 172: http://www.xxxx.com/discuz/images/default/right_big.gif?

仔细查看参数，发现请求的参数都是以明码的形式发送。

解决方法：在将勾选参数后面的：encode（先编码在发送请求）

再次运行，即可运行通过，如下图：
