Swagger-UI：504错误无法满足请求

如何解决Swagger-UI：504错误无法满足请求

我尝试将swagger-ui用于基于Az App-Service的我自己的API。但是执行时会出错。

＃以下curl命令适用于本地。

卷曲：

curl -X POST "http://<url>/process?parse_id=00001&cust_id=1503&ou_id=317" \
-H  "accept: application/json; charset=utf-8" \
-H  "Content-Type: multipart/form-data" \
-F  "data=@1503.pdf;type=application/pdf"
