Probot文档提到可以像在Vanilla Express服务器中一样使用路由。
我想为这些路由设置CORS原始标头。在香草Express服务器中,我将使用cors软件包:
const cors = require('cors')
...
app.use(cors())
但是probot应用程序不具有该功能use
。
module.exports = app => {
app.use(cors(corsOptions));
// ...
导致错误:
ERROR (event): app.use is not a function
TypeError: app.use is not a function
如何设置CORS?
您必须以编程方式启动该应用程序。这样,您可以在Probot加载后但Probot开始运行之前访问Express应用:
const cors = require("cors");
const bodyParser = require("body-parser");
const { Probot } = require("probot");
const { corsOptions } = require("./src/util/init-server.js");
const endpoint = require("./src/controller/endpoint");
const { handleWhatever } = require("./src/controller/controller");
// https://github.com/probot/probot/blob/master/src/index.ts#L33
const probot = new Probot({
id: process.env.APP_ID,
port: process.env.PORT,
secret: process.env.WEBHOOK_SECRET,
privateKey: process.env.PRIVATE_KEY,
webhookProxy: process.env.WEBHOOK_PROXY_URL,
});
const probotApp = app => {
/** Post a comment on new issue */
app.on("issues.opened", async context => {
const params = context.issue({ body: "Hello World!" });
return context.github.issues.createComment(params);
});
/** --- Express HTTP endpoints --- */
const router = app.route("/api");
router.use(cors(corsOptions)); // set CORS here
router.use(bodyParser.json());
router.use(bodyParser.urlencoded({ extended: true }));
// router.set("trust proxy", true);
// router.use(require('express').static('public')); // Use any middleware
router.get("/ping", (req, res) => res.send("Guten Tag! " + new Date()));
router.post(endpoint.handleWhatever , handleWhatever );
};
/** --- Initialize Express app by loading Probot --- */
probot.load(probotApp);
/* ############## Express instance ################ */
const app = probot.server;
const log = probot.log;
app.set("trust proxy", true);
/** --- Run Probot after setting everything up --- */
Probot.run(probotApp);
