BAD REQUEST received if the method name is not upper cased

NSxfer::Transfer /URL https://httpbin.org/post /LOCAL none /METHOD post /DATA '{"number_of_the_beast" : 666}' /HEADERS "Content-Type: application/json" /END
Pop $0 ; "Bad Request"

NSxfer::Transfer /URL https://httpbin.org/post /LOCAL none /METHOD POST /DATA '{"number_of_the_beast" : 666}' /HEADERS "Content-Type: application/json" /END
Pop $0 ; "OK"

Thank you for developing such a good plug-in, but download https url doesn't get status code

Example:
https://www.virustotal.com/gui/file/779bf93c33ad762a92f60f48822c294aa0f48b6304f43894f61eccd9b4fbf242/detection

The code has been working perfectly before, but recently when I migrate my domain name to cloudflare, the code couldn't get memory content, It show Remote-Content: "".Is there any way to solve this problem?

Thank you very much.

          You can retrieve the memory content like this:

NSxfer::Request /URL "https://httpbin.org/get?param1=1&param2=2" /LOCAL memory /END
Pop $0		; Transfer ID
NSxfer::Wait /ID $0
Pop $1		; Wait for transfer to complete
NSxfer::Query /ID $0 /CONTENT /END
Pop $1		; Remote-content as string truncated to ${NSIS_MAX_STRLEN}. Empty string in case of errors
DetailPrint 'Remote-Content: "$1"'

Indeed, I've switched developent to NScurl.
It's built on top of libcurl which I think it's far superior to the native windows API.
With NScurl the same code would look like:

NScurl::http GET "https://httpbin.org/get?param1=1&param2=2" "MEMORY" /RETURN "@recvdata@" /END
Pop $0
DetailPrint 'Remote-Content: "$0"'

NScurl is newer and better. I recommend it.
Thanks for your kind words and enjoy my NSIS plugin(s)...

NSxfer::Transfer currently returns the transfer status (i.e. "OK" for success) but no other information.

Add a new parameter /RETURNID to instruct Transfer to return the unique request ID.
The ID can later be passed to NSxfer::Query to get additional information.

Example:

NSxfer::Transfer /URL "https://wikipedia.org" /LOCAL memory /RETURNID /END
Pop $0 ; Request ID

NSxfer::Query /ID $0 /ERRORTEXT /CONTENT /SPEED /END
Pop $1 ; Transfer status ("OK" for success)
Pop $2 ; Remote-Content from memory
Pop $3 ; Transfer speed (i.e. "50 MB/s")

When called from the .onInit NSIS function, transfers will not start.
This is a regression caused by the security checks added in GH-6.
Exported functions receive a NULL parent window during .onInit, which is quickly rejected by our new validations.
NULL windows should be treated as valid.

I am having an issue downloading larger files (5MB +). They stop at exactly 5.00 MB (5,242,880 bytes).

I am using NSIS 3.09 x86-unicode and tested on Windows 11 22H2 x64 and Windows Server 2016 x64.

The below is a simple script that can be used for testing.

OutFile NSxferTest.exe

	Pop $0

	NSxfer::Wait /ID $0 /END

	Pop $0

If I use NSxfer::Transfer the result on the stack is "OK".

Thank you for this great plugin. I noticed this plugin could download remote content to memory buffer, but how to retrieve memory content to Nsis script?

And I noticed you develop another plugin nsis-nscurl, which is best?

Hello,

Thanks for the great plugin.

I'm having an issue where calling NSxfer is causing stack corruption. I'm using the x86-unicode version v1.2023.4.9 with NSIS v3.08.

I was having an issue with $0 not being set to the correct value after calling a function, so I used the Debug plugin to take a look.

It looks like the stack is being emptied or having things placed back in it unpredictably after calling the plugin.

I pushed a bunch of strings containing "Stack test", then call the plugin, and then use Debug::Stack to check the stack.

Here's the stack immediately before NSxfer::Transfer:

Here's the stack immediately after:

As you can see, the only thing on the stack any more is the RETURNID from the plugin.

Here's the code I'm using to call the plugin in this case:
NSxfer::Transfer /MODE SILENT /URL "http://127.0.0.1:9100/transmission/rpc/" /METHOD "GET" /LOCAL "MEMORY" /RETURNID

The whole NSIS script: https://gist.github.com/sopadelata/7e34387adf4d411e00d0cb8df511b2f2#file-gistfile1-txt-L162

(relevant part @ line 162)

On rare occasions NSxfer might hang when unloading
It happens when calling NSxfer::Query only, and no other exported function
When it happens the installer remains silently hung in the background
