please help me to solve this error.

Answer 1

Python requests does not handle data URLs by default. That is the meaning of the error message "No connection adapters were found." Python requests is able to handle http and https, but data URLs are quite different.

If your img_path string begins with "data:" then the easiest way is to handle that img_path value differently from the way you handle URLs.

See below for some sample code that handles the case where you have a data URL that begins with "data:" and you want to save the binary data encoded in base64.

if meta_og_image_content.startswith("data:"):
    # e.g., content="data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAeUAAACeEAIAAADTU..."

    first_128 = meta_og_image_content[:128]
    logger.info(
        f"found og:image inline data: '{first_128}...'"
    )

    match = re.match(
        r"^data: *([a-z]+/[a-z\-\+]+) *; *", meta_og_image_content
    )
    if match:
        len_match = len(match.group())
        reported_mimetype = match.group(1)

        meta_og_image_content = meta_og_image_content[len_match:]

        if meta_og_image_content.startswith("base64"):
            match = re.match(r"^base64 *[;,] *")
            if match:
                len_match = len(match.group())
                meta_og_image_content_encoded = meta_og_image_content[
                    len_match:
                ]

                # using base64, convert meta_og_image_content_encoded to binary data and save to a temp file
                local_file_with_og_image_inline_data_decoded = (
                    config.settings["TEMP_DIR"]
                    + f"og-image-via-inline-data-{id}"
                )
                binary_data = base64.b64decode(
                    meta_og_image_content_encoded
                )

                with open(
                    local_file_with_og_image_inline_data_decoded,
                    mode="wb",
                ) as file:
                    file.write(binary_data)

                og_image_is_inline_data = True

                logger.info(
                    f"saved og:image base64 inline data to {local_file_with_og_image_inline_data_decoded} {reported_mimetype=} {url=}"
                )

                og_image_inline_data_decoded_local_path = (
                    local_file_with_og_image_inline_data_decoded
                )
