无法使用REST API和curl从Azure文件存储中检索文件列表

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.
