when ever i m trying to run the script i got an error of "wsdl error: HTTP ERROR: no data present after HTTP headers" can any bdy help me regarding it?
This means that while the response contains headers (for example, a HTTP status code and content type) there is no data - i.e. no XML in the file.

I'm trying to get data from an OPeNDAP server using R and the ncdf4 package. However, the nasa eosdis server requires username / password. How can I pass this info using R?
Here is what I'm trying to do:
require(ncdf4)
f1 <- nc_open('https://disc2.gesdisc.eosdis.nasa.gov/opendap/TRMM_L3/TRMM_3B42.7/2018/020/3B42.20180120.15.7.HDF')
And the error message:
Error in Rsx_nc4_get_vara_double: NetCDF: Authorization failure syntax
error, unexpected WORD_WORD, expecting SCAN_ATTR or SCAN_DATASET or
SCAN_ERROR context: HTTP^ Basic: Access denied. Var: nlat Ndims: 1
Start: 0 Count: 400 Error in ncvar_get_inner(d$dimvarid$group_id,
d$dimvarid$id, default_missval_ncdf4(), : C function
R_nc4_get_vara_double returned error
I tried the url https://username:password#disc2.... but that did not work also.
Daniel,
The service you are accessing is using third-party redirection to authenticate users. Therefore the simple way of providing credentials in the URL doesn't work.
You need to create 2 files.
A .dodsrc file (a RC file for the netcdf-c library) with the following content
HTTP.COOKIEFILE=.cookies
HTTP.NETRC=.netrc
A .netrc file, in the location referenced in the .dodsrc, with your credentials:
machine urs.earthdata.nasa.gov
login YOURUSERNAMEHERE
password YOURPASWORDHERE
You can find more details at

Regards
Antonio
unfortunately, even after defining the credentials and their location
ncdf4::nc_open("https://gpm1.gesdisc.eosdis.nasa.gov/opendap/GPM_L3/GPM_3IMERGDE.06/2020/08/3B-DAY-E.MS.MRG.3IMERG.20200814-S000000-E235959.V06.nc4")
still returns
Error in Rsx_nc4_get_vara_double: NetCDF: Authorization failure
The same happens when using ncdump from a terminal:
$ ncdump https://gpm1.gesdisc.eosdis.nasa.gov/opendap/GPM_L3/GPM_3IMERGDE.06/2020/08/3B-DAY-E.MS.MRG.3IMERG.20200814-S000000-E235959.V06.nc4
returns
syntax error, unexpected WORD_WORD, expecting SCAN_ATTR or SCAN_DATASET or
SCAN_ERROR context: HTTP^ Basic: Access denied. NetCDF: Authorization

I have an application URL. I need to run login test using Jmeter. I recorded the login steps using blazemeter extension of chrome. But when I run it I get below error. I know there have been questions like this, I have tried few and it seems my case is different.
I have tried:
Added these two lines in jmeter.bat
set JAVA_HOME=C:\Program Files\Java\jdk1.8.0_65
set PATH=%JAVA_HOME%\bin;%PATH%
Run Jmeter using "Run as Administrator"
Download the certificate from here https://gist.github.com/borisguery/9ef114c53b83e553b635 and install it this way
https://www.youtube.com/watch?v=2k581jcWk9M
Restart the Jmeter but and try again but no luck.
When I expand the error in Jmeter View tree listener I get error on this particular css file: https://abcurl.xyzsample.com/assets/loginpage/css/okta-sign-in.min.7c7cfd15fa939095d61912dd8000a2a8.css

If you are getting error for only one .css file and it does not belong to the application under test (i.e. it is an external stylesheet) the best thing you could do is just to exclude it from the load test via URLs must match section which lives under "Advanced" tab of the HTTP Request Defaults configuration element.
If you need to load this .css by any means you could also try the following approaches:
Play with https.default.protocol and https.socket.protocols properties (look for the above lines in jmeter.properties) file
Install Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy Files into /jre/lib/security folder of your JRE or JDK home (replace existing files with the downloaded ones)
If your url needs a client certificate, then copy your cert to /bin folder and from the jmeter console if you go to options -> SSL Manager and select your cert , it would prompt you for the certificate password . And if you run your tests again , that should work .
Additionally you can also do keystore configuraion (http://jmeter.apache.org/usermanual/component_reference.html#Keystore_Configuration) , if you haven't done already .
Please Note that my jmeter version is 4.0 . Hope this helps .
The webpage I am trying to access downloads an attachment but header status is always 500 which I have checked through postman.
I am using download.file with wget method in R to download that file but it stops and doesn't download since the header status is 500. How can I manage to download this file irrespective of the header status?
When I access this link in browser, the file is downloaded just fine.
Edit:
Here's how I use download.file function in R:
download.file(get(url), destfile=tmpFile, method = "wget");
I tried to pass the extra argument like:
download.file(get(url), destfile=tmpFile, method = "wget", extra =getOption("content-on-error"));
and
download.file(get(url), destfile=tmpFile, method = "wget", extra =getOption("--content-on-error=0"));
but it doesn't work

Hi I'm trying to write a script using R where I post data to a specific weblink and get the response back. I'm not really sure how to set curl headers for Content-type and Application.
this is what I have so far:
library("RCurl")
httpPOST("http://localhost", '{"title":"ello World!"}')
I get the following error:
Error in curlOptions(..., .opts = .opts) : unnamed curl option(s):
....
If use curl from command line the data does get posted.
Is there another library in R that does CURL and JSON posts better?
