I am making an HTTP request using Apache JMeter.
The response has the following format:
HTTP/1.1 100 Continue
HTTP/1.1 200 OK
x-powered-by: Express
access-control-allow-origin: *
access-control-allow-methods: HEAD, POST, PUT, GET, OPTIONS, DELETE
access-control-allow-headers: origin, content-type, X-Auth-Token, Tenant-ID, Authorization
content-type: application/json; charset=utf-8
content-length: 24
etag: W/"18-8MkH0L5c1ZW7PPuEY1rZ3jKFme0"
date: Thu, 08 Apr 2021 12:28:37 GMT
x-envoy-upstream-service-time: 90
server: envoy
{"id":"548b23a3.4f6a4c"}
I need a way to extract the JSON id value to a variable to make another one request.
JSON extractor needs a pure JSON format as response but in my case i need to skip all these headers from the body response.
Any ideas how could i make it with the Apache JMeter?
If you really have all this as a part of response body (however it looks like Headers to me) you should always be able to fall back to the Regular Expression Extractor which doesn't have any limitations.
Example regular expression:
"id"\s*:\s*"(.+?)"}
Demo:
Explanation:
\s - meta character for whitespace
* - any number of whitespaces
. - match any character
+ - repetition
? - don't be greedy, stop at first match

Another clean way is to use is JSON Extractor (Post Processor). This is pretty helpful when you will have complex json (multiple nested objects) returned.

I am getting below Header Response :-
HTTP/1.1 202 Accepted
Content-Length: 0
Location: https://localhost:111/api_path/916e0a93-552f-46fd-84c4-6cecac92209a
Server: Microsoft-IIS/10.0

how can I use regular expression to capture the below value from Location ?
916e0a93-552f-46fd-84c4-6cecac92209a
I am not saving my response in file and i want a value of Location from Response Header
I tried below way but getting NOT FOUND as it is default, if i remove default then it will show null
Replace your regular expression with
Location: https:.+api_path\/(.*?)\n
Make sure you use Apply to Main sample only.
This what my HTTP request is generating
Content-Type: multipart/form-data; boundary=V0a4bfuxfGhaH_Voo_Gu6oAEtj5FJNcp; charset=UTF-8
However, when compared to the POST data, it is lacking the 2 dashes in the front, which causes the server to reject the request:
--V0a4bfuxfGhaH_Voo_Gu6oAEtj5FJNcp
Content-Disposition: form-data; data="dataToBeSent"
--V0a4bfuxfGhaH_Voo_Gu6oAEtj5FJNcp--
How do I get Jmeter to generate the dashes in the header?
(besides from manually creating the multipart form)
Note:
I am using the 'Use multipart/formdata for POST' option.
If I intercept the request and manually add the dashes in the header, the
server accepts the request.
You don't need to generate these values, the solution is to tick Use multipart/form-data for POST box in the HTTP Request sampler (or in the HTTP Request Defaults)
If you have any definition of Content-Type header in the HTTP Header Manager - you need to remove it and let JMeter generate appropriate Content-Type header on its own.
The header doesn't need the dashes. This is simply how multipart/form-data works. The body is built as follows:
--<boundary>
<headers>
<content>
--<boundary>
<headers>
<content>
--<boundary>--
The -- part indicates a new part starts. The body ends with ---- to indicate no new parts will follow.
I am trying to construct a HTTP Request through JMeter that uses a multipart data body.
I have a HTTP Header Manager that has COntent-Type set to multipart/form-data; boundary=AaB03x. I selected 'Use multipart/form-data for POST'.
I then have a data body created as,
`-----------------------------AaB03x
Content-Type: application/json
Content-Disposition: form-data; name="part1"
{"jsonKey1": "JsonValue1" }
-----------------------------AaB03x
Content-Type: application/json
Content-Disposition: form-data; name="part2"
{
"jsonKey2": "JsonValue2"
}
-----------------------------AaB03x
Content-Type: application/octet-stream
Content-Disposition: form-data; name="part3"
File Content here!!!!
-----------------------------AaB03x`
When I run this, I see that the request doesnt send the body correctly, instead it just sends some random data as,
POST data:
--vKOghkU7riRQbaANmmGpMs7j9TxCTUp3S2T0vE--
And gives an error response of,
`{"errorMsg":"Unable read headers from MultipartStream.","messageCode":"UnableReadHeadersFromMultipartStream","httpStat us":"BAD_REQUEST","requestName":"RequestName"}`
My second question is:
the part3 of the request sends a file to upload. Can I pass the file path somehow?
Given you set your own boundary and build your request manually I believe you need to uncheck Use multipart/form-data for POST in the HTTP Request Sampler
If your file encoding isn't very "exotic" you can try using __FileToString() function just instead of File Content here!!!!.
Looking into RFC 7578, it seems you also need a trailing -- at the end of the last line
You should try sending your JSON data as parameters. Also put your file path in the section for that... And even some servers don't actually need MIME type explicitly declared, you can check yours with some online tool like this one.
Your HTTP Request could look smethnig like:
I want to capture response Header Location : specifically 100 number so i can use it as variable in another request. How can i do this ?
Request
Remote Address: 57.98.32.25:80
Request URL:http://57.98.32.25/new_events
Request Method:POST
Status Code:200 OK
Response Headers
Cache-Control:no-cache
Connection:close
Content-Encoding:gzip
Content-Length:105
Content-Type:text/html;
Date:Thu, 27 Aug 2015 06:37:31 GMT
Location:http://57.98.32.25/new_events/100
Server:Apache/2.2.15
You can do it via Regular Expression Extractor configured as follows:
Field to check: Response Headers
Reference Name: anything meaningful, i.e. location
Regular Expression: new_events/(\d+)
Template: $1$
You may also need to switch "Apply to" value to "Main sample and sub-samples" if there are redirects and the Location header is not available in the main sample, use View Results Tree listener to determine it.
Refer extracted value as ${location} or ${__V(location)} where required.
I have a HTML-page, that's encoded in ISO-8859-1 and a Prototype-AJAX call that's build like this:
new Ajax.Request('api.jsp', {
method: 'get',
parameters: {...},
onSuccess: function(transport) {
var ajaxResponse = transport.responseJSON;
alert(ajaxResponse.msg);
}
});
The api.jsp returns its data in ISO-8859-1. The response contains special characters (German Umlauts) that are not displayed correctly, even if I add a "encoding: ISO-8895-1" to the AJAX-request. Does anyone know how to fix this?
If I call api.jsp in a new browser window separately the special characters are also corrupt. And I can't get any information about the used encoding in the response header. The response header looks like this:
Server Apache-Coyote/1.1
Content-Type application/json
Content-Length 208
Date Thu, 29 Apr 2010 14:40:24 GMT
Notice: Please don't advice the usage of UTF-8. I have to deal with ISO-8859-1.
Just found the answer myself. Though this is for PHP I'm sure you can find the equivalent for ASP :)
Basically, just include the encoding header on your response page (in your case api.asp), like this:
header("Content-Type: text/html; charset=ISO-8859-1");
Good luck with it :)
