问题
I need help to print an entity with Rest in shell script. I tried several ways, but without success.
Here is my code, running it, it will return all entities in my table.
But I need it to return only a specific value and that is only using PartitionKey.
#!/bin/bash
# List the tables in an Azure storage container.
storage_account="Secret"
table_name="teste"
access_key="Secret"
table_store_url="table.core.windows.net"
authorization="SharedKey"
request_method="GET"
request_date=$(TZ=GMT LC_ALL=en_US.utf8 date "+%a, %d %h %Y %H:%M:%S %Z")
#request_date="Mon, 18 Apr 2016 05:16:09 GMT"
storage_service_version="2018-03-28"
# HTTP Request headers
x_ms_date_h="x-ms-date:$request_date"
x_ms_version_h="x-ms-version:$storage_service_version"
# Build the signature string
canonicalized_resource="/${storage_account}/${table_name}"
string_to_sign="${request_method}\n\n\n$request_date\n${canonicalized_resource}"
# Decode the Base64 encoded access key, convert to Hex.
decoded_hex_key="$(echo -n $access_key | base64 -d -w0 | xxd -p -c256)"
# Create the HMAC signature for the Authorization header
signature=$(printf "$string_to_sign" | openssl dgst -sha256 -mac HMAC -macopt "hexkey:$decoded_hex_key" -binary | base64 -w0)
authorization_header="Authorization: $authorization $storage_account:$signature"
curl -s \
-H "$authorization_header" \
-H "$x_ms_date_h" \
-H "$x_ms_version_h" \
-H "Content-Length: 0" \
-H "accept: application/json;odata=nometadata" \
"https://${storage_account}.${table_store_url}/${table_name}"
In this case, I need to change the end of the string "string_to_sign" and the last line of the Curl.
If I insert at the end (PartitionKey='name',RowKey = 'Gabriel')"
Getting the two lines like this:
string_to_sign = "$ {request_method} \ n \ n \ n $ request_date \ n $ {canonicalized_resource} (PartitionKey = 'name', RowKey = Gabriel)"
"https://${storage_account}.${table_store_url}/${table_name}(PartitionKey='nome',RowKey='Gabriel')"
It will return only the entity with PartitionKey "name" and Rowkey "Gabriel".
But as I said before, I must use only Partition Key. If I change the end of the two lines to (PartitionKey = 'name') only, it returns the following error:
The number of keys specified in the URI does not match number of key properties for the resource
I tried using the $ filter option, changing the end of the two lines to ()$filter=(PartitionKey%20ge%20'Name'), however it happens error when passing through the Printf.
By putting ()$filter=(PartitionKey%%20ge%%20'Name'), Two %, it passes, but occurs authentication error on request.
Server failed to authenticate the request. Make sure the value of Authorization header is formed correctly including the signature
Can someone help me?
I need to use PartitionKey because in these tests I am using a table that I created and I have the value of RowKey for tests, but where I need to implement, I do not have access to RowKey, I would pass the value of PartitionKey which is a telephone number to obtain the result of the RowKey, which is an Id.
Used the following documentation:
- https://docs.microsoft.com/en-us/rest/api/storageservices/table-service-rest-api
- https://docs.microsoft.com/en-us/rest/api/storageservices/query-entities
回答1:
No need to change string_to_sign when querying entity, see Authorization Header.
The query string should include the question mark and the comp parameter (for example, ?comp=metadata). No other parameters should be included on the query string.
If you want to get whole entity using PartitionKey, change url to($ need encoding to %24)
https://${storage_account}.${table_store_url}/${table_name}?%24filter=PartitionKey%20eq%20'YourPartitionKey'
Or if you only want to retrieve RowKey, append &%24select=RowKey after that.
Also -H "Content-Length: 0" is useless, just delete it.
