我正在尝试使用node-red作为前端来与我正在构建的 REST API 交互。我的 API 使用 https，但在我的本地服务器上，证书没有完美设置，当我尝试使用“http 请求”节点时出现错误：

 UNABLE_TO_VERIFY_LEAF_SIGNATURE

有没有办法将 node-red 配置得不那么严格并允许 SSL 协议错误并继续处理 http 请求？有没有人创建了他们自己版本的“http 请求”节点，它比默认的更严格？

（在 Google Chome 浏览器中，我有一个绿色挂锁，所以 SSL 几乎是正确的，node-red 非常挑剔）

要运行 node-red，我使用 docker：

docker run -dp 1880:1880 -v ~/.node-red:/root/.node-red --name node-red cpswan/node-red

这是我的节点红色项目源代码：

目前，node-red 没有直接公开执行此操作的方法，但您可以设置NODE_TLS_REJECT_UNAUTHORIZED环境变量以在 node.js 级别禁用它：

例如：

NODE_TLS_REJECT_UNAUTHORIZED=0 node red.js

settings.js在文件中添加以下代码。module.exports行前

process.env.NODE_TLS_REJECT_UNAUTHORIZED = "0";

如果要查找文件位置，请运行 node-red 它，也会显示文件位置。

In case it helps anyone, here is how you can try node-red using Docker without HTTPS errors using the ENV var that @knolleary brought to light (NODE_TLS_REJECT_UNAUTHORIZED=0):

Create a Dockerfile with this inside:

FROM node:0.10
RUN npm install -g node-red
EXPOSE 1880
ENV NODE_TLS_REJECT_UNAUTHORIZED=0
CMD ["/usr/local/bin/node-red"]

Build it:

docker build -t="yourname/node-red" .

Run it:

docker run -dp 1880:1880 -v ~/.node-red:/root/.node-red --name node-red yourname/node-red

Browse to: http://127.0.0.1:1880/

If you need the node-red app to access services running on the host, you can add the name of the service to /etc/hosts of the node-red container referencing the docker gateway IP:

docker exec node-red sh -c "echo '172.17.42.1\tmy.local.service.com\n' >> /etc/hosts"

After this, a node-red "http request" node can use my.local.service.com in the url.

我在 ubuntu 20.04 LTS 上使用snapd安装了node-red

如果有人在 ubuntu 上使用此工具遇到同样的问题，请查看：

/etc/systemd/system/snap.node-red.node-red.service

节点红服务定义

你会发现应用程序正在使用/etc/environment文件来设置环境变量

更新

改为EnvironmentFile=..._Environment="NODE_TLS_REJECT_UNAUTHORIZED=0"

之后，使用以下命令重新启动 systemd 和 snap.node-red 服务：

sudo systemctl daemon-reload && service snap.node-red.node-red restart

确保服务正在运行：

sudo service snap.node-red.node-red status
