在使用 openapi Braid 为我的 corda 项目生成 api 时，它在最后一个 steep 中显示了一些错误

Question

Downloads\bootcamp-openapi-master\bootcamp-openapi-master\build\nodes>openapi-generator generate -i http://localhost:10200/swagger.json -g javascript -o ./code-gen --
api-package io.generated.api --model-package io.generated.model

我正在尝试处理 corda openapi 生成项目，但它在最后一步向我显示上述错误。 我正在努力工作的项目是
https://blog.b9lab.com/cordacon-2019-highlights-braid-server-and-openapi-generator-for-corda-flows-api-s-d24179ccb27c和类似的https://github.com/corda/openapi -样本

但问题是我做了与链接中显示相同的操作，但我生成 api 的最后一步没有执行并抛出上述错误。 还有一件事是我的一步显示的输出与 Git 中显示的输出不同。

我的输出

不同之处在于它们不包含https ，但我认为这不会引发任何错误。

Answer 1

在您的 Braid 服务器输出中，它表示activating OpenAPI V2意味着您的服务器正在生成具有 OpenAPI 规范版本2的 API，而您的 openapi-generator 正在抛出错误ERROR io.swagger.v3.parser.util.RemoteUrl意味着它正在寻找v3 （不是v2 ) 这就是它无法解析文件的原因。
在我的 Medium 文章（和 R3 教程）中，我们都使用v3 。
从我的文章（注意10200之后的3 ：

localhost:10004 user1 test 10200 3 “/home/your-user/path-to-project/bootcamp-openapi/build/nodes/PartyA/cordapps”

来自 R3 的文章（注意我们如何使用openapi version 3 ）：

Now, find the down triangle to open up the run configuration. At the Program arguments, paste in: 
localhost:10004 user1 test 10200 3 
"/YOUR-PATH-TO-THIS-FOLDER/bootcamp-cordapp/build/nodes/PartyA/cordapps"

RPC connection address: localhost:10004
node login username: user1
node login password: test
Your desired expose port: 10200
openapi version: 3
Cordapp folder to pick up the jar: "YOUR-PATH-TO-THIS-FOLDER/bootcamp-cordapp/build/nodes/PartyA/cordapps"

所以我不确定你为什么决定使用版本2 。
