Calling an API Locally

Prerequisites

• You have obtained a HUAWEI ID and completed real-name authentication. Your HUAWEI ID is not in arrears, frozen, or deregistered.
• You have learned the constraints on Text Moderation.
• You have subscribed to the Text Moderation service.

Procedure

1. Install the Python environment and obtain the SDK.
   1. Download Python of a proper version from Python's official website and install it. Python 3.3 or later is recommended. This section uses Python 3.7 as an example.
   2. Download the latest version of PyCharm from PyCharm's official website.
   3. Start the PyCharm development tool and choose File > Settings > Project Interpreter to configure the Python environment.
   4. Select the Python installation path. See Figure 1. After selecting the target Python, click Apply at the bottom of the page to complete the configuration.

2. Create a project in PyCharm and click Terminal in the lower left corner. Run the following commands to install the SDK (the SDK supports Python 3 or later):

   Install the SDK using pip commands:
   # Install the core library.
   pip install huaweicloudsdkcore
   
   # Install the Moderation service library.
   pip install huaweicloudsdkmoderation

   On PyCharm, choose File > Settings > Project > Python Interpreter. Click + in the upper right corner, search for huaweicloudsdkcore and huaweicloudsdkmoderation respectively, and click Install Package in the lower left corner to install them.

3. Copy the SDK sample code of Text Moderation to PyCharm as follows:

   # coding: utf-8
   from huaweicloudsdkcore.auth.credentials import BasicCredentials
   from huaweicloudsdkmoderation.v2.region.moderation_region import ModerationRegion
   from huaweicloudsdkcore.exceptions import exceptions
   from huaweicloudsdkmoderation.v2 import *
   if __name__ == "__main__":
       //Enter your AK/SK.
       ak = "<YOUR AK>"
       sk = "<YOUR SK>"
       credentials = BasicCredentials(ak, sk) \
       client = ModerationClient.new_builder() \
           .with_credentials(credentials) \
           .with_region(ModerationRegion.value_of("ap-southeast-1")) \  
           .build()
   try:
           request = RunTextModerationRequest()
           listItemsbody = [
               TextDetectionItemsReq(
                   text="asdfasdfasdf"   //Enter the text to be detected, for example, asdfasdfasdf.
               )
           ]
           request.body = TextDetectionReq(
               items=listItemsbody
           )
           response = client.run_text_moderation(request)
           print(response)
       except exceptions.ClientRequestException as e:
           print(e.status_code)
           print(e.request_id)
           print(e.error_code)
           print(e.error_msg)

4. Obtain the AK and SK and replace <YOUR AK> and <YOUR SK> in the sample code with the AK and SK, respectively.

   Log in to the My Credentials page, choose Access Keys in the navigation pane on the left, and click Create Access Key in the right pane.

5. Run the sample code to obtain the recognition result. You can interpret the review result based on the response parameter description. For details, see Text Moderation Result.
