Avoid the conversion on error when loading the document in Python with urllib3

In this guide, we'll show you how to abort the conversion when loading the distant source does not return a 2XX response.

When you're converting a document, you might want to avoid the conversion on error when loading the document. This can be done by setting the raise_for_status parameter to True in the request.

import urllib3, json, base64

# You can get an API key at https://pdfshift.io
api_key = 'sk_xxxxxxxxxxxx'

params = {
    'source': 'https://www.httpstat.us/404',
    'raise_for_status': True
}

http = urllib3.PoolManager()
response = http.request(
    'POST',
    'https://api.pdfshift.io/v3/convert/pdf',
    headers={
        'Content-Type': 'application/json',
        'Authorization': 'Basic {}'.format(
            base64.b64encode('api:{}'.format(api_key).encode('utf-8')).decode('utf-8')
        )
    },
    body=json.dumps(params).encode('utf-8')
)

if response.status != 200:
    raise ValueError(f"Request failed with status code {response.status}: {response.data.decode('utf-8')}")

with open('result.pdf', 'wb') as f:
    f.write(response.content)

print('The PDF document was generated and saved to result.pdf')

Passing raise_for_status to true will ensure that if PDFShift can not load your document, the conversion will fail with an error.

For further details on the raise_for_status property and its usage, please refer to our dedicated documentation.
