How to download a url whith libcurl and donot unzip it - libcurl

By default, libcurl will download a url, if the url is gzipped (content-type: gzip), libcurl will unzip it,
Is it possible that let libcurl do not unzip it?

No, libcurl will not by default decompress a response body that is sent compressed. It would only do that automatically if you set CURLOPT_ACCEPT_ENCODING accordingly.
The default behavior by libcurl is to deliver the data to the application exactly and unmodified, as it was sent by the server.

How to get content of the post request file POSTMAN

I have a problem with sending files to some API. When I do it via my server some pdf files send correctly but some not. But when I send the same pdf via POSTMAN everything works just fine. I am not sure what is the reason (probably POSTMAN encodes it into base64 but from my server, I send it in binary - just a guess). Is there a way to get the sent request file content from postman so that I can imitate it and compare with the request on my server?

Microsoft Graph API - Error: The Content-Range header length does not match the provided number of bytes

I am trying to upload a file to the Shared Documents library of my SharePoint website. The files are of type PDF and HTML. I am running a Cold Fusion development environment and using CFHTTP commands to execute HTTP requests. I have been able push a POST command and a PUT command to the proper endpoints listed on this link below:
Link: https://learn.microsoft.com/en-us/graph/api/driveitem-createuploadsession?view=graph-rest-1.0#best-practices
I do not understand why but the first section that mentions the HTTP requests for creating an upload session is different than what was used in the example a little further. For my project, I am using the endpoint:
"/{variables.instance.microsoftGraphAPIURL}/drive/root:/{item-path}:/createUploadSession"
P.S. variables.instance.microsoftGraphAPIURL is a variable to a microsoft graph endpoint to our Sharepoint website
With better luck using PUT commands than POST commands for creating an Upload Session. I am able to receive an uploadURL, but the issue comes with trying to upload the file. For the file upload, I am trying to upload a file in the same directory with a file size of 114992 bytes. I keep getting "The Content-Range header length does not match the provided number of bytes." whenever I run my Put command to upload the file.
Thus, my Content-Range is "bytes 0-114991/114992" and my Content-Length is "114992". For the image below, I replaced the file with a pdf, but the original file was an HTML page at 114992 bytes. I want to use a resumable upload session to have one function for uploading image, HTML, and PDF files.
If anyone could tell me if there is an issue with my content headers or my upload session http request or anything else that is causing my issue, that would be amazing! Thank you.

Giving value to parameter from a file to send it through HTTPPOst

I have been struggling with Jenkins lately, and I'm stuck because I wanna send some parameters through HTTP Post, and I know how to do it, but the thing is that I am saving a Http request response to a file in my workspace, and then I want to use that file, read it and send the text I saved previously to a new HTTP Request, does anyone have any idea how can I achieve this?
Thanks in advance!!!
Install copy artifacts from another project plugin ( copy artifacts) add in build steps store the file in your workspace then you can run a shell script to read the desired content from that file .
if curl would work, that would be a simple way to send a file's contents as your POST body. see this answer.
Jenkins can work with Jmeter and Jmeter is great tool for handling request and response see tutorial

Cannot open own media files after AWS S3 download with libCurl + headers

I already asked this question in the AWS Developer Forum without getting any response. So here goes:
I download my own media files from my own AWS S3 bucket using my own libCurl C++ application.
If I mark a file as public and download it with a simple libCurl GET request (no additional headers), the downloaded file works perfectly fine.
However, if I mark the exact same file as private and add headers to the GET request (Host, x-amz-date, x-amz-content-sha256 and the Authorization Header), I cannot open the downloaded file.
My question is:
Why does adding headers to the GET request alter the downloaded file?
And what can I do to fix this?
UPDATE: Using a hex editor I found out, that the HTTP response is written into the received file at the beginning.
How can I prevent that?
Thanks in advance!
I found the solution. Just had to remove this line from my code:
curl_easy_setopt(curl, CURLOPT_HEADER, true);
Initially, I thought this line would allow me to add additional headers to my HTTP request...
Instead, it includes the HTTP response in the output, which was my problem.

What is the simplest library to download files in C++

I want to download files that I have the full URL address using my c++ program, which library is the best to do this?
I was wondering for a command like:
system("download [URL] [DESTINATION]");
or
download(URL,DESTINATION);
I am using Windows, sorry that I forgot to mention.
You have not mentioned the operating system, anyways you can do that using system function in c.
#include <stdio.h>
int main()
{
system("wget url");
return 0;
}
Change url to get the file you needed.
have a look at curl
from curl site
curl is a command line tool for transferring data with URL syntax, supporting DICT, FILE, >FTP, FTPS, Gopher, HTTP, HTTPS, IMAP, IMAPS, LDAP, LDAPS, POP3, POP3S, RTMP, RTSP, SCP, >SFTP, SMTP, SMTPS, Telnet and TFTP. curl supports SSL certificates, HTTP POST, HTTP PUT, FTP uploading, HTTP form based upload, proxies, cookies, user+password authentication (Basic, Digest, NTLM, Negotiate, kerberos...), file transfer resume, proxy tunneling and a busload >of other useful tricks.
Its the best client side library available
http://curl.haxx.se/
libcurl is one of the widely used multi-protocol network transfer libraries. It can be used for downloading files or pages over HTTP and lot of other protocols.
The command line client curl is built on top of the libcurl library.
for a call to system("command"); you could use some command line tools that can achieve a download. wget and curl are such tools. the later even provides an API for C so you can write you own download(...) function.
