原始字符串包含“ +”，正则表达式提取器（。+？）将其替换为空格。 我如何用“ +”提取

Question

(Edit: The answer is to use check 'Encode?'option in the HTTP Request. Please see Vinoth's Edit 2 and comment below, thanks!)

This is interesting!

I'm trying to parse a HTTP response which has (let's give concrete example,

bigH:"2a3a6CEH+iJakQpQtPm8efv"

Using Regular Expression Extractor when I try

bigH:"(.+?)"

it extracts the string but replaces all the "+" in the string with space. That is, instead of

"2a3a6CEH+iJakQpQtPm8efv" 

it gives me:

"2a3a6CEH iJakQpQtPm8efv"

Note the space between H and i.

How can I stop it from replacing the "+" with a space? I'd really appreciate if someone can give an explanation also.

Btw, I tried (.+?) and (.\\++?) and even ([.|\\+]+?) - didn't work :(

Thanks, --Ishtiaque

After parsing with regular expression extractor in JMeter:

Side by side in Notepad++:

'Raw' tab shows the '+'s:

'HTTP' tab does not:

Answer 1

尝试使用正则表达式([a-zA-Z0-9+]+)

Answer 2

As you get the response in JSON format, I would go with JSON Path Extractor .

It seems to be a much easier approach than using Regular expression.

Below JSON Path should take care of getting the encoded string from your JSON & You should be able to access using ${bigH} .

Check this for more details (scroll down for JSON Path extractor details).

I was wrong that You get the response in JSON format. Are you trying to access - bigH:"XXX" - from script tag? For this, We have to use Regular expression extractor only or Beanshell.

<script type='text/javascript' charset='utf-8'>

I doubt that you might have checked the Encode in the HTTP Request.
Uncheck
