Question

如何用OAS 2.0生成nodejs-server作为openapi-generator的输入？

openapi-generator在两个版本3.3.4和4.0.0上运行。我的执行结果列在下面。

■在3.3.4中

java -jar openapi-generator-cli-3.3.4.jar generate -i petstore.json -g nodejs-server -o stub
[main] WARN  o.o.c.ignore.CodegenIgnoreProcessor - Output directory does not exist, or is inaccessible. No file (.openapi-generator-ignore) will be evaluated.
[main] WARN  o.o.c.languages.NodeJSServerCodegen -

=======================================================================================
Currently, Node.js server doesn't work as its dependency doesn't support OpenAPI Spec3.
For further details, see https://github.com/OpenAPITools/openapi-generator/issues/34

■在4.0.0版中

java -jar openapi-generator-cli-4.0.0.jar generate -i petstore.json -g nodejs-server -o stub
[main] WARN  o.o.c.ignore.CodegenIgnoreProcessor - Output directory does not exist, or is inaccessible. No file (.openapi-generator-ignore) will be evaluated.

输入的OAS使用以下内容。

https://raw.githubusercontent.com/OAI/OpenAPI-Specification/master/examples/v2.0/json/petstore.json

执行环境如下。

・ windows10

・ java 1.8.0_202

它对我有用：

java -jar modules/openapi-generator-cli/target/openapi-generator-cli.jar generate -g nodejs-server -i https://raw.githubusercontent.com/OAI/OpenAPI-Specification/master/examples/v2.0/json/petstore.json -o /tmp/nodejs-server
[main] INFO  o.o.codegen.DefaultGenerator - OpenAPI Generator: nodejs-server (server)
[main] INFO  o.o.codegen.DefaultGenerator - Generator 'nodejs-server' is considered stable.
[main] WARN  o.o.c.languages.NodeJSServerCodegen -

但是如警告中所述，nodejs-server生成器不再按预期工作，因为其依赖项之一不支持OpenAPI规范v3。
