SOLVED Update category picture (via image upload) API not working


  • @baris We did not try that way, we tried files[0]=

    Now I'm getting 403 Forbidden, with invalid csrf token in the logs.

    2021-10-22T23:54:52.993Z [4567/19620] - error: /api/admin/category/uploadpicture
    invalid csrf token
    

    How do I get around the invalid token?


  • Here is the verbose output from my macbook:

    Note: Unnecessary use of -X or --request, POST is already inferred.

    I see the message "We are completely uploaded and fine" in the above. But ultimately am getting the invalid token error over and over.

    I think you have to first load a regular route and get a csrf token and then use that in your POST call. I am not sure how to do that in curl. Our tests do it using request https://github.com/NodeBB/NodeBB/blob/master/test/helpers/index.js#L14 and then storing the cookies then we use it to make POST requests.

    This worked for me give it a try

    # get csrf token and save cookies
    curl http://127.0.0.1:4567/api/config -c cookies.txt -s | grep csrf
    
    #this will print something like
    "csrf_token": "bHqyDEde-Y_zLYuitkD4uc5Cd7-0mYF1m5GU",
    

    Copy the value of the csrf_token and make the upload also use cookies.txt with -b cookies.txt

    curl -H "Authorization: Bearer da21bf5f-6924-4e5d-9a82-92191e6f2240" -XPOST \
      -F params="{\"cid\":\"2\"}" \
      -F "files[][email protected]:\ideas.png" \
      -F "_csrf=bHqyDEde-Y_zLYuitkD4uc5Cd7-0mYF1m5GU"  \
      -b cookies.txt \
      http://127.0.0.1:4567/api/admin/category/uploadpicture
    

    Should get this output

    [
        {
            "name": "ideas.png",
            "url": "/assets/uploads/category/category-2.png"
        }
    ]
    

  • @baris we are definitely close. That process works, I do get the success output, but the image doesn't appear as the category image. It just stays the default background color.

  • NodeBB

    That could be due to cache, did you try clearing the object cache at /admin/advanced/cache?


  • @baris thanks, just tried that and it didn't work. Is there a 3rd step to actually placing the image?

  • NodeBB

    Ahh yes you need to set the backgroundImage property of category:2 to the value of "url": "/assets/uploads/category/category-2.png"


  • @baris Thank-you, found it, it is a PUT on the write API. First go, I got the syntax mostly correct, I got a 200 OK message, but the Response:backgroundImage key was empty.

    I will poke at this more after dinner, but I think we can call this one solved, since it is just a matter of figuring out the right syntax at this point.


  • @baris Using the below site, reminding me of just how powerful Chrome Developers tools are, I was able to Copy As Curl the specific PUT command.

    Curl Convert

    Then using the same command and just changing the CID, I confirmed the same command works for all of them.

    This is what ended up working, it includes all the recorded headers, of which some will be removed as not necessary:

    curl 'http://pubdump.unfufadoo.net:4567/api/v3/categories/80' \
      -X 'PUT' \
      -H 'Connection: keep-alive' \
      -H 'Accept: */*' \
      -H 'DNT: 1' \
      -H 'x-csrf-token: H5FMJEaY-CthHWM_2Unzf7DtoPeryGq_JejE' \
      -H 'X-Requested-With: XMLHttpRequest' \
      -H 'User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/94.0.4606.81 Safari/537.36' \
      -H 'Content-Type: application/json; charset=UTF-8' \
      -H 'Origin: http://pubdump.unfufadoo.net:4567' \
      -H 'Referer: http://pubdump.unfufadoo.net:4567/admin/manage/categories/80' \
      -H 'Accept-Language: en-US,en;q=0.9,zh;q=0.8,zh-CN;q=0.7,zh-TW;q=0.6,ja;q=0.5,ko;q=0.4,th;q=0.3' \
      -H 'Cookie: _csrf=27ygKMdG0c0EyiVsJKAkKpId; express.sid=s%3AdODaXfUpLz7NTFsijWLq0d2rPUhH1Ki4.qkyxWOaxlBy%2BLDRpTYbhWS9QkD9IJE%2FRTN1vIhp7yV4' \
      -H 'sec-gpc: 1' \
      --data '{"backgroundImage":"/assets/uploads/category/category-84.jpg"}' \
      --compressed \
      --insecure
    

    Then using the cURL convert site, was able to save as javascript and modify to our needs so that we could loop through all categories.
