OAS3 的 Swagger Codegen

Question

我正尝试将 Swagger Codegen 用于我的 OAS3 项目。 我已经克隆了 swagger-codegen 分支 3.0.0。当我 运行 生成命令时，出现以下错误：

[main] ERROR io.swagger.parser.SwaggerCompatConverter - failed to read resource listing
com.fasterxml.jackson.core.JsonParseException: Unrecognized token 'openapi': was expecting ('true', 'false' or 'null')

 at [Source: (String)"openapi: 3.0.0

Codegen是否支持openapi 3.0.1？如果是，我错过了什么？

更新 - Yaml 文件和代码生成命令

Petstore.yaml 文件：

Codegen 命令：

SCRIPT_DIR="$( cd "$( dirname "${BASH_SOURCE[0]}" )" >/dev/null 2>&1 && pwd )"

java -jar ./swagger-codegen/modules/swagger-codegen-cli/target/swagger-codegen-cli.jar generate -i "./definitions/petstoreV3.yaml" -l javascript -o "$SCRIPT_DIR/.swagger_gen_temp"

Answer 1

发生错误是因为您是 运行 V2 codegen（来自 master 分支）而不是 V3 codegen（来自 3.0.0 分支）。 V2 codegen 不支持 OpenAPI 3.0.

您可以从以下地址下载 V3 codegen 的 JAR：
http://central.maven.org/maven2/io/swagger/codegen/v3/swagger-codegen-cli/3.0.11/swagger-codegen-cli-3.0.11.jar

但是，V3 codegen 当前没有 JavaScript 客户端生成器。
