I have created a script in JMeter to download a file and now I have to get the name of the downloaded file [filename] from sampler response to store it in a csv file,
I have tried to configure the sampler response but it didn't help me out.
please see the following
Response headers:
HTTP/1.1 200 OK
Cache-Control: private
Pragma: no-cache
Content-Length: 1235270
Content-Type: application/octet-stream
Expires: Mon, 20 Apr 2015 12:10:35 GMT
Server: Microsoft-IIS/6.0
content-disposition: attachment; **filename="10098_testcase_package.pct**"
If you need to get "filename" bit from response header you can use Regular Expression Extractor post processor for it
Add Regular Expression Extractor as a child of the request which returns the header
Configure it as follows:
Field to check: Response Headers. It matters as by default the Extractor looks up in the response body and you need the header.
Reference Name: any variable name, i.e filename
Regular Expression: filename="(.+?)"
Template: $1$
Other fileds may be left blank
You can refer extracted value as ${filename} where required.
For more information on correlation in JMeter check out Using RegEx (Regular Expression Extractor) with JMeter guide.

I am trying to upload a file using the PUT method, which is not including the file in the request. I have followed the other example POST methods, but considering PUT does not allow multipart to be checked, that might be the issue.
I am also using:
* httpClient4
* jmeter 3.3

Request data:
PUT http://myurl----here/app_path/test__16525587b4361f339ca33a9cdf0e9201d90e76dc__1676871c-71b8-488a-9750-29554a4be722
PUT data:
[no cookies]
Request Headers:
Connection: close
Content-Type: application/octet-stream
Content-Length: 0
Host: int-cloudstore-perf.svc.netspot.com.au
User-Agent: Apache-HttpClient/4.5.3 (Java/9.0.1)
Your test does't seem to be sending anything as your Put data should not be blank.
I would recommend to remove data from the Parameter Name section of the "Files Upload" tab of the HTTP Request sampler as PUT method is different and it doesn't assume submitting an HTML form and most probably your request will start working as expected (at least it will send data to the server)
Just in case check out Testing REST API File Uploads in JMeter article
I have tried to upload the file in jmeter:
Please find below mentioned details which i passed in request,
Http reuest:
POST: http:${server_name}/attachment
1.File Path : D:\localdrive\test_docs\images.jpg
2.Parameter Name:images.jpg
3.MIME Type:image/jpg
Http Header :
1.Accept : / ,
2.Content-Type : multipart/form-data
Response Data :
{"response":"the request was rejected because no multipart boundary was found"}
could anyone please share the solution on the same .
Got it !!!
Make sure that below parameter should be mentioned in HTTP request.
Implementation should be HttpClient3.1 or Java (Don't keep it blank)
Content encoding :UTF-8
"Use multipart/form-data for Post" in HTTP sample should be checked.
In HTTP header (Content-Type : multipart/form-data)
for Parameter-name & MIME-type
e.g. In browser enter F12 & hit the request ,
refer the content in Network tab :
Inside Param u will get request param
for example if param is :
HTML contains= Content-Disposition: form-data; name="file"; filename="images.jpg" Content-Type: image/jpeg
Then Parameter-name :file & MIME-type :image/jpeg should be like this.
& now its work fine ,That's a great relief for me !!!
also thanks Anders for ur answer.
HTML contains=
Content-Disposition: form-data; name="file";
filename="images.jpg" Content-Type: image/jpeg
So i have set =
Parameter-name :file MIME-type :image/jpeg ; In sample request i have already checked "Use multipart/form-data for Post" which i have not mentioned early.
Then also its not work ...
anything else which i missed here
There is a checkbox inside the sampler which uploads the file that says "Use multipart/form-data for Post" which needs to be checked.
If your HTML looks something like this input type="file" name="dataFile" id="fileChooser"/>" your parameter name must be "dataFile" which is the name of the input file field.
You can also use a sniffer tool like fiddler for example or the HTTP/S script recorder JMeter has to capture the request and check the MIME Type for example because I'm not sure if jpg files are "image/jpg" MIME Type
Make sure those are correctly formatted and check out what BlazeMeter says about uploading files
I have a program that uses an XMLHTTPRequest to gather contents from another web page.
Problem is, that web page has cloaking custom errors set-up (ie. /thisurl doesn't literally exist as a file on their web server, it is being generated by the custom 404 error file.), so its not returning the page it shows in the browser, instead its showing its default 404 error response from that custom error page, in my HTTPRequest response.
By using this website http://web-sniffer.net/ I have narrowed down what the problem may be, but I don't know how to fix it.
Web-sniffer has 3 different versions to submit the request:
HTTP version: HTTP/1.1
HTTP/1.0 (with Host header)
HTTP/1.0 (without Host header)`
When I use HTTP/1.1 or HTTP/1.0 (with Host header) I get the correct response (html) from the page. But when I use HTTP/1.0 (without Host header) it does not return the content, instead it returns a 404 error script (showing the custom error page).
So I have concluded that the problem may be due to the Host header not being present in the request.
But I am using MSXML2.XMLHTTP.3.0 and haven't been able to read the page using HTTP/1.1 or HTTP/1.0 (with Host header). The code looks like this:
Set objXML = Server.CreateObject("MSXML2.XMLHTTP.3.0")
objXML.Open "GET", URL, False
objXML.setRequestHeader "Host", MyDomain '< Doesnt work with or w/out this line
objXML.Send
Even after adding a Host header to the request, I still get the template of the 404 error returned by that custom error script in my response, the same as HTTP/1.0 (without Host Header) option on that web-sniffer site. This should be returning 200 OK like it does on the first two options on web-sniffer, and like in a web browser.
So I guess my question is, what is that website (web-sniffer.net) able to get the proper response with their first two HTTP version options, so I can emulate this in my app. I want to get the right page, but its only returning the 404 error from their 404 error template.
In response to an answerer, I have provided screen shots from 2 seperate cUrl requests below, one from each one of my servers.
I executed the same cURL command, same url (that points to a site on the main host), which is cURL -v -I www.site.com/cloakedfile . But looks like its not working on the main server, where it needs to be. It can't be a self-residing issue, because from secondary to secondary it works fine, these are both identical applications/sites, just different ip's/host names. It appears to be an internal issue, that may not be about the application side of things.
I dont have any idea bout MSXML2.XMLHTTP.3.0. But from you problem statement i understand that the issues is certainly due to some HTTP header field that is wrongly set or missed out in your request.
By default HTTP 1.1 clients set Host header. For example if you are connecting to google.com then the request will look like this
GET / HTTP/1.1
Host: google.com
The "Host" header should have the domain name of the server in which the requested resource is residing. Severs that has virtual hosting will get confused if "Host:" header is not present. This is what happens with groups.yahoo.com if you havent specified Host header
$ nc groups.yahoo.com 80
GET / HTTP/1.1
HTTP/1.1 400 Host Header Required
Date: Fri, 06 Dec 2013 05:40:26 GMT
Connection: close
Via: http/1.1 r08.ycpi.inc.yahoo.net (ApacheTrafficServer/4.0.2 [c s f ])
Server: ATS/4.0.2
Cache-Control: no-store
Content-Type: text/html; charset=utf-8
Content-Language: en
Content-Length: 447
And this should be the same issue you are facing with. And also make sure that you are sending the domain name of the server from which you are trying to fetch the resource. And the Host header should have a colon ":" to delimit the value like "Host: www.example.com".
I am working on a chrome extension which modifies the http response headers.
https://chrome.google.com/webstore/detail/super-cache/fglobbnbihckpkodmeefhagijjcjnbeh/details
I am not able to cache main_frame requests. I am able to control the caching of the static requests though.
For example if I hit http://apple.com I receive the following headers for the main_frame.
Accept-Ranges:bytes
Cache-Control:max-age=276
Connection:keep-alive
Content-Encoding:gzip
Content-Length:3310
Content-Type:text/html; charset=UTF-8
Date:Tue, 12 Mar 2013 09:24:12 GMT
Expires:Tue, 12 Mar 2013 09:28:48 GMT
Server:Apache
Vary:Accept-Encoding
But every time I hit the url the browser tries to access the server and ultimately receive a 200 response. I have tried all the possible combinations that the headers can be set to enable caching on the main_frame.
I want that when the user hits the url from the navigation bar of chrome and no requests are made.
You're missing some sort of cache validation in your response headers. ETag header can be used to control that, by adding values to it that would identify a unique response. You can read a bit about it in the Apache ETag documentation, but I'd simply include ETag: [filename] in your response headers in your example:
Accept-Ranges:bytes
Cache-Control:max-age=276
Connection:keep-alive
Content-Encoding:gzip
Content-Length:3310
Content-Type:text/html; charset=UTF-8
Date:Tue, 12 Mar 2013 09:24:12 GMT
Expires:Tue, 12 Mar 2013 09:28:48 GMT
Server:Apache
ETag: File:"somefile.html"
Vary:Accept-Encoding
These ETag values can include pretty much anything, such as file name, file size, custom values,... that can be separated by a semicolon ;. If the values include spaces, then enclose them in double quotation marks ". For Example:
ETag: File:"YouTube_cd_Fdly3rX8.jpg"; Size:12169
Together with Cache-Control, Expires and some other header values that might change (when included and browser knows how to interpret them), will form a basis for Browser's cache validator.
Looking at your sample response headers, you might want to increase the max-age value in your Cache-Control to a lot higher value, as your example suggest they should be cached client-side for only 276 seconds. The Expires header value also seems a bit short.
More on how to set these values and how browsers are expected to validate cache control headers can be read in the RFC2616, Section 14.9.
EDIT: After further debugging, checking and re-checking the behavior of Chrome's cache validation, it turns out it indeed doesn't respect properly set Cache-Control response headers. On request of the OP, I've reported this issue to the Chrome support:
Chrome, Version 25.0.1364.172 m
Disrespecting Cache-Control on main document requests when serving
static files from a web server, while respecting same header response
on linked contents.
Test setup:
Requesting a static HTML document from a web server (MIME text/html),
that contains another static HTML document withing an IFRAME (also
MIME text/html). The IFRAME served document has same response headers
attached to it by a web server response as the main document:
Date: Thu, 21 Mar 2013 16:29:28 GMT
Expires: Thu, 21 Mar 2013 16:33:59 GMT
Cache-Control: max-age=301, max-stale=299, only-if-cached
Expected behavior:
Main document and the document served within an IFRAME will be cached
locally with initial request for the duration of at least 301
(max-age) seconds, and additional 299 (max-stale) seconds for normal
(non-forced) load requests. Any subsequent requests within this
time-frame of 301 seconds that aren't expected to invalidate local
cache (such as forced-refresh with CTRL+F5 or Reload context menu
command) and are initiated by a normal page load request (e.g.
re-entering relevant URL in the address bar) will be loaded from the
local cache with a status message 200 OK (from cache), if none of the
local cache controlling information indicates it otherwise (same URL,
requested within valid cache time-frame, document was tagged to be
cached in its response headers correctly).
Problem:
The main document is not loaded via its cached copy and an additional
request is made to the web server, resulting in a status code 304 Not
Modified. The document within an IFRAME however is loaded from the
local cache correctly and results in a status message 200 OK (from
cache).
Notes:
None of the cache-control tags or any combination of their values seem
to have any positive effect on the behavior of local cache for the
main document. Including a non-unique ETag value does not resolve the
problem of caching main document either. Other major vendor browsers
(tested in IE, Firefox, Opera) respect Cache-Control headers on main
document.
Using Ruby, how do I convert the short URLs (tinyURL, bitly etc) to the corresponding long URLs?
I don't use Ruby but the general idea is to send an HTTP HEAD request to the server which in turn will return a 301 response (Moved Permanently) with the Location header which contains the URI.
HEAD /5b2su2 HTTP/1.1
Host: tinyurl.com
Accept: */*
RESPONSE:
HTTP/1.1 301 Moved Permanently
Location: http://stackoverflow.com
Content-type: text/html
Date: Sat, 23 May 2009 18:58:24 GMT
Server: TinyURL/1.6
This is much faster than opening the actual URL and you don't really want to fetch the redirected URL. It also plays nice with the tinyurl service.
Look into any HTTP or curl APIs within ruby. It should be fairly easy.
You can use the httpclient rubygem to get the headers
#!/usr/bin/env ruby
require 'rubygems'
require 'httpclient'
client = HTTPClient.new
result = client.head(ARGV[0])
puts result.header['Location']
There is a great wrapper for the bitly API in Python available here:
http://code.google.com/p/python-bitly/
So there must be something similar for Ruby.
