When using the DocFlow API, if the file category name contains Chinese or other non-English characters, passing the raw category name may cause the following issues:
  1. Category matching failure: API cannot correctly recognize Chinese category names
  2. Processing errors: Returns error messages that the category does not exist
  3. Encoding issues: URL parameters containing non-ASCII characters cause request failures

​
Solution

​
1. URL Encoding Processing

Chinese category names must be UTF-8 URL encoded before being passed as API parameters.

​
Python Example

import urllib.parse

# Original Chinese category name
category = "发票"

# URL encoding
encoded_category = urllib.parse.quote(category)
print(f"After encoding: {encoded_category}")
# Output: %E5%8F%91%E7%A5%A8

​
JavaScript Example

// Original Chinese category name
const category = "发票";

// URL encoding
const encodedCategory = encodeURIComponent(category);
console.log(`After encoding: ${encodedCategory}`);
// Output: %E5%8F%91%E7%A5%A8
