From f9fb595feeba637ad11a1f18d44c050bdffd2b14 Mon Sep 17 00:00:00 2001 From: Rander7 Date: Thu, 4 Jun 2026 10:09:28 +0800 Subject: [PATCH 1/7] refactor: use PaddleOCR Python SDK instead of direct API calls MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ## Why This Refactoring Is Necessary PaddleOCR 3.6.0+ has migrated to a new async Job API architecture where requests are submitted, then polled for completion. The legacy sync API will be deprecated, making this refactoring critical for long-term maintenance. Benefits of using the official SDK: - **Future-proof**: Aligns with PaddleOCR's official API evolution - **Better reliability**: Built-in retry logic, timeout handling, error classification - **Reduced maintenance**: No need to manually implement poll loops and error handling - **Consistent behavior**: Same implementation as PaddleOCR's own tools (CLI, MCP) ## Breaking Changes **None for end users** - the tool interface and output format remain identical. The plugin continues to accept the same credentials and file inputs. ## Internal Changes ### Dependencies - Replaced `requests` with `paddleocr>=3.6.0` ### SDK Integration - Added `get_sdk_client()` with `client_platform="dify"` header - Added Base64 → temp file conversion (SDK requires file_path/file_url) - Added result format converters to maintain legacy output structure ### Code Simplification - Removed manual HTTP request handling (`make_paddleocr_api_request`) - Removed manual poll loops (SDK handles submit → poll → fetch) - Updated credential validation to use SDK ## Testing All three tools maintain their original behavior: - Text Recognition (PP-OCRv5) - Document Parsing (PP-StructureV3) - VL Document Parsing (PaddleOCR-VL-1.6) ---

Use lazy imports for paddleocr SDK to avoid requiring it for tests.

11:54:38 +0800 Subject: [PATCH 5/7] Refactor PaddleOCR integration to use official SDK This commit migrates from direct HTTP API calls to the official PaddleOCR SDK (>=3.6.0), which simplifies integration and improves maintainability. Key changes: - Use public API imports from paddleocr package instead of internal modules - Implement unified camelCase to snake_case parameter conversion - Remove unnecessary result format conversion functions - Simplify credential configuration: base_url is now optional (uses SDK default if not provided) - Update provider validation to use SDK for testing - Add manual test script for validation - Update tests to mock public API instead of internal modules User-facing changes: - Configuration simplified: only token is required for official service - base_url is optional (only needed for self-hosted deployments) - All core OCR and document parsing features continue to work as before Testing: - All 12 unit tests pass - Manual tests confirm OCR (URL and Base64) and document parsing work correctly Co-Authored-By: Claude Opus 4.7 --- tests/tools/paddleocr/test_file_input.py | 22 +- tools/paddleocr/provider/paddleocr.py | 91 ++---- tools/paddleocr/provider/paddleocr.yaml | 54 +--- tools/paddleocr/test_manual.py | 318 +++++++++++++++++++ tools/paddleocr/tools/document_parsing.py | 81 +++-- tools/paddleocr/tools/document_parsing_vl.py | 83 +++-- tools/paddleocr/tools/text_recognition.py | 28 +- tools/paddleocr/tools/utils.py | 257 +++++---------- 8 files changed, 589 insertions(+), 345 deletions(-) create mode 100644 tools/paddleocr/test_manual.py diff --git a/tests/tools/paddleocr/test_file_input.py b/tests/tools/paddleocr/test_file_input.py index e4dd38a42..f57580465 100644 --- a/tests/tools/paddleocr/test_file_input.py +++ b/tests/tools/paddleocr/test_file_input.py @@ -8,15 +8,25 @@ # Mock paddleocr module before any imports mock_paddleocr = MagicMock() + +# Mock public API classes +mock_paddleocr.PaddleOCRClient = MagicMock +mock_paddleocr.OCROptions = lambda **kw: MagicMock() +mock_paddleocr.PPStructureV3Options = lambda **kw: MagicMock() +mock_paddleocr.PaddleOCRVLOptions = lambda **kw: MagicMock() +mock_paddleocr.AuthError = Exception +mock_paddleocr.PaddleOCRAPIError = Exception + +# Mock internal modules for backward compatibility mock_paddleocr._api_client = MagicMock() -mock_paddleocr._api_client.PaddleOCRClient = MagicMock +mock_paddleocr._api_client.PaddleOCRClient = mock_paddleocr.PaddleOCRClient mock_paddleocr._api_client.models = MagicMock() -mock_paddleocr._api_client.models.OCROptions = lambda **kw: MagicMock() -mock_paddleocr._api_client.models.PPStructureV3Options = lambda **kw: MagicMock() -mock_paddleocr._api_client.models.PaddleOCRVLOptions = lambda **kw: MagicMock() +mock_paddleocr._api_client.models.OCROptions = mock_paddleocr.OCROptions +mock_paddleocr._api_client.models.PPStructureV3Options = mock_paddleocr.PPStructureV3Options +mock_paddleocr._api_client.models.PaddleOCRVLOptions = mock_paddleocr.PaddleOCRVLOptions mock_paddleocr._api_client.errors = MagicMock() -mock_paddleocr._api_client.errors.AuthError = Exception -mock_paddleocr._api_client.errors.PaddleOCRAPIError = Exception +mock_paddleocr._api_client.errors.AuthError = mock_paddleocr.AuthError +mock_paddleocr._api_client.errors.PaddleOCRAPIError = mock_paddleocr.PaddleOCRAPIError sys.modules["paddleocr"] = mock_paddleocr sys.modules["paddleocr._api_client"] = mock_paddleocr._api_client diff --git a/tools/paddleocr/provider/paddleocr.py b/tools/paddleocr/provider/paddleocr.py index 957c84cd6..e3b68432f 100644 --- a/tools/paddleocr/provider/paddleocr.py +++ b/tools/paddleocr/provider/paddleocr.py @@ -6,7 +6,7 @@ from tools.document_parsing import DocumentParsingTool from tools.document_parsing_vl import DocumentParsingVlTool from tools.text_recognition import TextRecognitionTool -from tools.utils import extract_base_url +from tools.utils import get_sdk_client class PaddleocrProvider(ToolProvider): @@ -16,74 +16,33 @@ def _validate_credentials(self, credentials: dict[str, Any]) -> None: "AI Studio access token must be provided" ) -

Key changes: - tools/utils.py: Implement HTTP async Job API (_submit_job, _poll_job, _parse_*) - Replace client.ocr()/parse_document() with call_paddleocr_api() - Use same API endpoint /api/v2/ocr/jobs, Bearer token auth, poll strategy - Keep all utility functions (file handling, camel_to_snake) unchanged - No changes to provider.yaml config or pyproject.toml dependencies Changes: +461/-480 lines, 6 files modified Co-Authored-By: Claude Opus 4.7 --- tools/paddleocr/provider/paddleocr.py | 27 +- tools/paddleocr/test_manual.py | 318 ------------- tools/paddleocr/tools/document_parsing.py | 41 +- tools/paddleocr/tools/document_parsing_vl.py | 41 +- tools/paddleocr/tools/text_recognition.py | 39 +- tools/paddleocr/tools/utils.py | 475 +++++++++++++++---- 6 files changed, 461 insertions(+), 480 deletions(-) delete mode 100644 tools/paddleocr/test_manual.py diff --git a/tools/paddleocr/provider/paddleocr.py b/tools/paddleocr/provider/paddleocr.py index e3b68432f..eb1d3b4a6 100644 --- a/tools/paddleocr/provider/paddleocr.py +++ b/tools/paddleocr/provider/paddleocr.py @@ -6,7 +6,7 @@ from tools.document_parsing import DocumentParsingTool from tools.document_parsing_vl import DocumentParsingVlTool from tools.text_recognition import TextRecognitionTool -from tools.utils import get_sdk_client +from tools.utils import call_paddleocr_api, get_sdk_client class PaddleocrProvider(ToolProvider): @@ -23,26 +23,19 @@ def _validate_credentials(self, credentials: dict[str, Any]) -> None: test_file = "https://paddle-model-ecology.bj.bcebos.com/paddlex/imgs/demo_image/general_ocr_002.png" try: -
