1. Component introduction
Required preceding components: None
Recommended subsequent components: Conditional Branch. Use a conditional branch to check if the OCR call was successful, and then design the subsequent flow.
This component uses Optical Character Recognition (OCR) technology to recognize text in images from online scenarios, such as E-commerce product promotions, online forums, and user-generated content (UGC). For more information, see Recognize text in E-commerce images.
2. Inputs
For information about each input, see the help text in the component panel of the application flow editor.
3. Outputs
For information about each output, see the help text in the component panel of the application flow editor.
3.1. Key API return results
This output returns a dictionary that contains key recognition results from the API. The following table describes the key-value pairs in the dictionary.
Key |
Key description |
Value data type |
content |
A summary of the recognized text blocks from the image. |
String |
3.2. Error message
This output returns the error code and error message as a string. For more information, see the OCR Error Center.

4. Component usage example
4.1. Component configuration example
Set the AI engine to Alibaba Cloud OCR.
For Path of the image file to recognize, enter the file path of the image. This example uses the following image.
Keep the default values for the advanced options.
4.2. Example execution result
5. Flow example
5.1. Build the flow
Use the Recognize text in E-commerce images with OCR component and specify the path of the image file to recognize.
Use the Conditional Branch component to determine whether the OCR call was successful. Set the branch condition to v_basic_success_1 is equal to the Boolean value True.
In the success branch, use the Get value of a specified key component to retrieve the value of the content key from the v_basic_data_1 dictionary.
Use the Record Log component to record the key recognition result.
In the failure branch, use the Record Log component to record the error message.
5.2. Execution result
As shown in the following figure, after the OCR call is successful, the recognition result is printed in the log panel.
