WSO2 APIM 4.0.0创建API正常但调用返回404及CORS错误如何解决？

排查修改步骤 #

1. CORS配置生效范围修正
   全局[apim.cors]配置仅对新增API生效，存量已创建的API（包括测试用的pizzashack示例API）需要手动触发规则同步：
   进入Publisher平台对应API的「运行配置」页，启用CORS配置，确认规则和全局配置一致后重新发布API。

2. 网关标签匹配修正
   当前配置存在网关标签不匹配问题，导致API发布后未同步到运行网关，引发404错误。需修改deployment.toml中网关环境配置，补充标签字段：

[[apim.gateway.environment]]
name = "Production"
type = "production"
display_in_api_console = true
description = "This is a hybrid gateway that handles both production and sandbox token traffic."
show_as_token_endpoint_url = true
service_url = "https://apim-p.<redacted dns>.com:${mgt.transport.https.port}/services/"
username= "${admin.username}"
password= "${admin.password}"
ws_endpoint = "ws://apim-p.<redacted dns>.com:9099"
wss_endpoint = "wss://apim-p.<redacted dns>.com:8099"
http_endpoint = "http://apim-p.<redacted dns>.com:${http.nio.port}"
https_endpoint = "https://apim-p.<redacted dns>.com:${https.nio.port}"
websub_event_receiver_http_endpoint = "http://apim-p.<redacted dns>.com:9021"
websub_event_receiver_https_endpoint = "https://apim-p.<redacted dns>.com:8021"
# 新增标签配置，和同步规则的label保持一致
label = "Default"

3. 端口与访问验证
   确认虚拟机防火墙/安全组已开放以下默认端口：

• 网关HTTPS端口：8243
• 网关HTTP端口：8280
• 管理控制台端口：9443
  API发布时选择「Production」网关环境，调用前验证接口地址前缀与网关配置的https_endpoint/http_endpoint完全一致。

4. 配置生效验证
   修改deployment.toml后重启WSO2 APIM服务，重新发布测试API后再进行调用验证。
