Hi,
I'm trying to diagnose some issues with accessing remote datasets in
GDAL - I believe the problem is unrelated to GDAL itself, but it's
proving hard to debug.
By enabling CPL_CURL_VERBOSE, I can see that the server is kicking
back a 400 Bad Request status, but the debug output doesn't include
the actual response content, which would allow me to understand the
problem in more detail. Is there a way to get GDAL/cURL to output the
response content for failed requests?
By way of example, if I attempt to access a nonexistent file on S3
with cURL directly, I get the 404 error code and the descriptive
XML error message at the end:
$ curl -v https://a-very-very-fake-s3-bucket.s3.amazonaws.com/example.tif
[...]
< HTTP/1.1 404 Not Found
< Content-Type: application/xml
< Transfer-Encoding: chunked
< Date: Wed, 06 Jul 2022 11:09:09 GMT
< Server: AmazonS3
--- these lines ---
<
<?xml version="1.0" encoding="UTF-8"?>
<Error><Code>NoSuchBucket</Code><Message>The specified bucket does not
exist</Message><BucketName>a-very-very-fake-s3-bucket</BucketName>[...]</Error>
--- these lines ---
In contrast, the output from GDAL with CPL_CURL_VERBOSE excludes the
XML response:
< HTTP/1.1 404 Not Found
< Content-Type: application/xml
< Transfer-Encoding: chunked
< Date: Wed, 06 Jul 2022 11:04:16 GMT
< Server: AmazonS3
--- no XML output here ---
