Description Pallawi 2019-06-03 06:44:14 UTC 
Hi,
I have a Post request in Jmeter in which, ViewState parameter is passing but value for that parameter is combination of alphabates, number, special characters . so while send that parameter request is encoding the special character for e.g. i have forward slash in paramter so while sending it is converting it to %2F and that leads in failing the request

Solution i have tried is:

uncheck URL Encode check box
UTF-8 in content encoding
for ViewState providing ${__urldecode('${viewState}')} value as Parameter value, which(viewState) i am fetching from previous response
used replace function in Parameter value
So what i am expecting is while sending Post request parameters should not get encoded. Can someone please provide solution

I have the same issue:
This is an extract from my JMeter session:
<pre>(Edited to save space)
name="__VIEWSTATE" id="__VIEWSTATE" value="h5lDhpLn0j5HofnHdSWCvYWJ/b29ZaIqaaEM….jOuPrEYMSxF+8Cxeeu2OqckZPPbOLdA=" />
</div>

Based on this the following request uses POST data:
__VIEWSTATEGENERATOR=019976AD&__EVENTARGUMENT=&__VIEWSTATE=h5lDhpLn0j5HofnHdSWCvYWJ%2Fb29ZaIqaaEM…JjOuPrEYMSxF%2B8Cxeeu2OqckZPPbOLdA%3D&__VIEWSTATEENCRYPTED=&ctl00%24ContentPlaceHolder%24password=Super01%24&__EVENTTARGET=&ctl00%24ContentPlaceHolder%24username=user1%40vizor.ie&__EVENTVALIDATION=K%2FJR4RydzHsK5jjEX1riK2RyzUNloKx64zL3T%2FvzFtOR2tTRdMAmC8WQCsqeiHVw%2BKWZnnfFprvyLrCjnPZ%2F9SIX%2BivNSHXDtvY7IYz4t3plqlH52ROW2YD%2B0qpXTlkSBhXlofuD5NgHMfpLQmf9Mjpo3vPRWMhpbGyZpujch8b7tb%2FDqAd12EhXt%2B%2BKOdTGI2CxpzGZ6Z%2FJFMISCt6v3glnOvP8%2BiqZlAFz0izek3FapbsYmrg3dNGW9s6EVejRi4caDzfsmMEpjIGtFVX%2BAg%3D%3D&ctl00

The positive is the I am  capturing the viewstate but it each ‘/’ in it is being escaped as ‘%2F’, and there are others too.


The post with the login details then fails with information including:
ViewState: K/JR4RydzHsK5jjEX1riK2RyzUNloKx64zL3T/vzFtOR2tTRdMAmC8WQCsqeiHVw+KWZnnfFprvyLrCjnPZ/9SIX+ivNSHXDtvY7IYz4t3plqlH52ROW2YD+0qpXTlkSBhXlofuD5NgHMfpLQmf9Mjpo3vPRWMhpbGyZpujch8b7tb/DqAd12EhXt++KOdTGI2CxpzGZ6Z/JFMISCt6v3glnOvP8+iqZlAFz0izek3FapbsYmrg3dNGW9s6EVejRi4caDzfsmMEpjIGtFVX+Ag==]
