Cannot retrieve file list from Azure File Storage using REST API and curl

Question

I'm trying to retrieve the list of files stored in an Azure File Storage account using the REST API and curl, I correctly computed headers according to the documentation by using the shared key , but curl request neither returns the files list nor any error message.

Here is my request and the response:

curl -v -H "Authorization: SharedKey myaccount:bAJKeY0xyOZLSJOLDoHfXXOqfA4kOGo1DVFP3BejhY8=" -H "x-ms-date:Mon, 13 Aug 2018 15:22:31 GMT" -H "x-ms-version:2017-07-29" --url https://myaccount.file.core.windows.net/myshare/mydir?restype=directory&comp=list

No XML with file list is returned. I tried to retrieve the share list under myaccount and it works, as well as downloading a single file, but I cannot receive the list of files under a directory.

Two points:

1. See url in curl command

    --url https://myaccount.file.core.windows.net/myshare/mydir?restype=directory&comp=list 

   You forget to put the url in "" so the parameter &comp=list is cut because & is a reserved sign. This is also proved by the output GET /myshare/mydir?restype=directory HTTP/1.1 .

2. Commonly speaking, if the url misses the comp parameter, we should get error message AuthenticationFailed because comp is used in generating SharedKey. However you get HTTP/1.1 200 OK with the SharedKey.

   Based on the response headers you get, I guess you also missed the comp when constructing the SharedKey, so the SharedKey and url is capable to get directory properties correctly.
