httpie uses the value of environment variable REQUESTS_CA_BUNDLE to verify if it is present.
Would be nice if xh uses it too.

[ducaale]

It doesn't seem to be mentioned in the docs but it is, in fact, something that HTTPie supports.

The library we use for parsing command-line arguments supports falling back to an env variable so this should be an easy one to implement. Would like to create a PR for it?

Edit: this has been implemented in #146

[blyxxyz]

requests checks both REQUESTS_CA_BUNDLE and CURL_CA_BUNDLE, so perhaps we should also look for both.

[ducaale]

So this means we can no longer use the nice API that structopt offers. If that is the case, we should manually check for those env variables inside the from_iter_safe() function and then set cli.verify from there.

xh does not process query parameter read from file as httpie does:

Prepare a file with value for query parameter

First we create a file with a value to use:

$ echo "filed-value" > arg.value

Use http, reading query parameter from the file

Then using http we ask to use this value read from the file for query parameter arg:

$ http https://httpbin.org/get arg==@arg.value
HTTP/1.1 200 OK
Access-Control-Allow-Credentials: true
Access-Control-Allow-Origin: *
Connection: keep-alive
Content-Length: 342
Content-Type: application/json
Date: Wed, 05 Oct 2022 23:11:13 GMT
Server: gunicorn/19.9.0

{
    "args": {
        "arg": "filed-value"
    },
    "headers": {
        "Accept": "*/*",
        "Accept-Encoding": "gzip, deflate",
        "Host": "httpbin.org",
        "User-Agent": "HTTPie/3.2.1",
        "X-Amzn-Trace-Id": "Root=1-633e0f11-6265bd27088a85585daa3a5d"
    },
    "origin": "185.151.252.82",
    "url": "https://httpbin.org/get?arg=filed-value"
}

As we can see, the response report the value for arg is "filed-value" as expected.

Use xh to read the query parameter from the file - fails with using the file name

Now try the same with xh:

$ xh https://httpbin.org/get arg==@arg.value
HTTP/2.0 200 OK
access-control-allow-credentials: true
access-control-allow-origin: *
content-length: 343
content-type: application/json
date: Wed, 05 Oct 2022 23:11:31 GMT
server: gunicorn/19.9.0

{
    "args": {
        "arg": "@arg.value"
    },
    "headers": {
        "Accept": "*/*",
        "Accept-Encoding": "gzip, deflate, br",
        "Host": "httpbin.org",
        "User-Agent": "xh/0.16.1",
        "X-Amzn-Trace-Id": "Root=1-633e0f23-1fbbb3d05048db3a7649a622"
    },
    "origin": "185.151.252.82",
    "url": "https://httpbin.org/get?arg=%40arg.value"
}

As can be seen, it did not read the value from the file, instead it used value of the file itself.

[ducaale]

Thanks, @vlcinsky. I have now included this in the feature compatibility checklist.

For reference, httpie/cli#1225 is the PR that added support for reading header and query string values from a file.

[vlcinsky]

@ducaale great.

Just a note: http does urlencoding for the values read from the file before putting it into final url string.
