call Telegram.api in browser (Windows): sendPhoto

I am using Telegram to send pictures from a IP-cam. This can be done on raspberry-PI like this:

curl -s -X POST "https://api.telegram.org/bot123456789:yourcode/sendPhoto" -F chat_id=123456789 -F photo="@/volume1/Data/temp/picture.jpeg"

Explanation: the picture is in the folder "/volume1/Data/temp" the name is "picture.jpeg"

I want to do the same on Windows and I constantly get message "{"ok":false,"error_code":400,"description":"Bad Request: Wrong persistent file_id specified: contains wrong characters or has wrong length"}"

This is exactly (exact for the bot and yourcode and chatid) what I transmit in the address of Google Chrome:

https://api.telegram.org/bot123456789:yourcode/sendPhoto?chat_id=123456789&photo="@C:/temp/picture.jpeg"

I can assure you the is no problem with autorisation (filling in file:///C:/temp/picture.jpeg in the browser shows me the picture). And I have tried al kinds of variantions (with and without @, with and without ", etc. etc.). I cannot get it working.

And it works with sending text:

...../sendMessage?chat_id=123456789&text=”hello”

result is that I get the message "hello" and this in the browser: {"ok":true,"result":{"message_id" ......

I am sure I am close but do not know how to define exactly the "picture".

So the questions is: what is the exact way to transmit a picture with Telegram through a Windows browser using api.telegram.org? Please provide an example that is working.

Thanks in advance for help!

When you transmit that url in chrome (or any other browser) you are actually using "GET" method than can be used for send image with its "file_id".

But when you want to upload a file from your pc, you should use "POST" method to send it.

On of easiest ways is using a HTML form.

For an example:

<form action="https://api.telegram.org/bot2222222:AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA/sendPhoto" method="post" enctype="multipart/form-data">

    <input type="text" name="chat_id" value="11111111" />
    <input type="file" name="photo"  />
    <input type="submit" value="send" />

</form>

Edit:

Also if you want to do it from command line you can use windows version of cUrl. You can download it from this link: Windows cUrl

or use Invoke-RestMethod in windows powershell. example command:

Invoke-RestMethod -Uri $uri -Method Post -InFile $filePath -ContentType "multipart/form-data"
