cURL and Azure BLOB with SAS - HTTP header that's mandatory for this request is not specified

I've reviewed the information at:

• https://docs.microsoft.com/en-us/rest/api/storageservices/put-blob
• https://docs.microsoft.com/en-us/rest/api/storageservices/service-sas-examples

As far as I can tell I am complying becuase I am posting the SAS in the URL.

Here is my simple test script:

#!/bin/bash

DATE_NOW=$(date -Ru | sed 's/\+0000/GMT/')
AZ_VERSION="2018-03-28"
AZ_BLOB_URL="https://XXXXXXXX.blob.core.windows.net"
AZ_BLOB_CONTAINER="XXXXXX"
AZ_BLOB_TARGET="${AZ_BLOB_URL}/${AZ_BLOB_CONTAINER}/"
AZ_SAS_TOKEN="?sv=2017-11-09&ss=b&srt=o&sp=rwlac&se=2021-11-06T01:05:33Z&st=2018-11-09T17:05:33Z&sip=192.0.2.0-192.0.2.254&spr=https&sig=XXXXXXXXXX"

curl -v -X PUT -H "Content-Type: application/octet-stream" -H "x-ms-date: ${DATE_NOW}" -H "x-ms-version: ${AZ_VERSION}" --data-binary "@/home/test/test" "${AZ_BLOB_TARGET}test${AZ_SAS_TOKEN}"

Running that yields:

> PUT /XXXX/XXXXX?sv=2017-11-09&ss=b&srt=o&sp=rwlac&se=2021-11-06T01:05:33Z&st=2018-11-09T17:05:33Z&sip=192.0.2.0-192.0.2.254&spr=https&sig=XXXXXXXXXX" HTTP/1.1

Solution 1:

The simple answer to your question is, you are missing -H "x-ms-blob-type: BlockBlob".

But you SAS Token might also be invalid after you fix the header, you are trying to upload a file using a SAS token that doe not have Container access and might have IP restrictions.

#!/bin/bash

DATE_NOW=$(date -Ru | sed 's/\+0000/GMT/')
AZ_VERSION="2018-03-28"
AZ_BLOB_URL="https://xxxxxx.blob.core.windows.net"
AZ_BLOB_CONTAINER="test"
AZ_BLOB_TARGET="${AZ_BLOB_URL}/${AZ_BLOB_CONTAINER}/"
AZ_SAS_TOKEN="?sv=2017-11-09&ss=b&srt=sco&sp=rwlac&se=2018-11-11T05:03:03Z&st=2018-11-10T21:03:03Z&spr=https&sig=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx%3D"

curl -v -X PUT -H "Content-Type: application/octet-stream" -H "x-ms-date: ${DATE_NOW}" -H "x-ms-version: ${AZ_VERSION}" -H "x-ms-blob-type: BlockBlob" --data-binary "/temp/test.log" "${AZ_BLOB_TARGET}test.log${AZ_SAS_TOKEN}"

Hope this helps.
