Why Does an API Failed to Be Called Across Domains?

  1. Ensure that CORS has been enabled for the API.

    Go to the API details page, click Edit, and check whether CORS is enabled. If it is not, enable it.

  2. Check whether an API with the OPTIONS method has been created. Only one such API is required for each API group.
    1. On the Set Basic Information page, set the basic information for the API that uses the OPTIONS method.

      Go to the API details page and click Edit.

      API Group: The group to which the API with CORS enabled belongs.

      Security Authentication: None means all users will be granted access. It is not recommended.

    2. On the Define API Request page, set the request information for the API.
      • Protocol: The same protocol used by the API with CORS enabled.
      • Path: Same as or prefixally matching the request path set for the API with CORS enabled.
      • Matching: Select Prefix match.
      • Method: Select OPTIONS.
      • CORS: Enable this option.
