第一个使用 WSO2 APIM 4.0.0 的 API，创建似乎很好，但尝试调用 API 时出现 HTTP 404

Question

I newly installed an instance of WSO2 API Manager 4.0.0 using the Simple Node configuration https://apim.docs.wso2.com/en/latest/install-and-setup/setup/single-node/configuring-a-single-node/ on a virtual machine.

I can create my APIs (with internal existing API, or pizzashack sample) in the WSO2 publisher. But when I try to call the API, using the try out menu, I have a simple 'TypeError: NetworkError when attempting to fetch resource.'

In the firefox browser console I have a 'CORS Missing Allow Origin' error on an OPTIONS call to the API manager. For this issue I've applied https://apim.docs.wso2.com/en/latest/design/advanced-topics/enabling-cors-for-apis/ but with no success.

Here's my deployment.toml file with the customization I made.

I already spent several days looking for answers within stackoverflow, WSO2 official documentations and WSO2 github, but with no success.

Did I missed something somewhere ?

Answer 1

I was facing the same issue until this morning. https://github.com/wso2/api-manager/issues/68

My context is a little bit different, i use a Docker active-active distributed deployment.

I think I played too much with the deployment.toml, because a remove and recreate container fix the problem.

I don't know if it can help but i added that :

[apim.sync_runtime_artifacts.gateway]
enable = true
gateway_labels =["Default"]

[apim.sync_runtime_artifacts.publisher]
artifact_saver = "DBSaver"
publish_directly_to_gateway = true
