Preidx Seed Oauth 回调报错 404

[lihongxun945]

问题：

登录之后跳转回应用的时候报错:

http://localhost:5000/callback?code=###,

{"message":"Not Found","error":{"status":404}}

服务器端报这个错误:

Error at C:\codes\predix-seed\node_modules\passport-oauth\lib\passport-oauth\strategies\oauth2.js:125:38 at C:\codes\predix-seed\node_modules\oauth\lib\oauth2.js:177:18 at ClientRequest.

回答：
在 passport中为了能正确处理 code，nodejs中会有一个回调url的定义。
在predix-seed中已经写好了这部分代码：
https://github.com/PredixDev/predix-seed/blob/develop/server/app.js#L107

1. //callback route redirects to secure route after login
2. app.get('/callback', passport.authenticate('predix', {
3. failureRedirect: '/'
4. }), function(req, res) {
5. console.log('Redirecting to secure route...');
6. res.redirect('/');
7. });

localConfig.json 文件中定义了定义了需要配置的 credential:

{
"development": {
"note": "Out of the box, the predix-seed app uses mock data, so these values are not required. Set these values for connecting to real Predix services.",
"clientId": "{UAA Client ID created}",
"uaaURL": "{The UAA URI end point to get auth token }",
"base64ClientCredential": "{Get clientID:clientSecret then base64 encode and place it here}",
"appURL": "http://localhost:5000",
"timeseriesURL": "{Time Series URL from VCAPS}",
"timeseriesZoneId": "{The Zone ID for the Timeseries Service Created}",
"assetURL": "{Asset URL from VCAPS}",
"assetZoneId": "{The Zone ID for the Asset Service Created}",
"windServiceURL": "{URL of the microservice <your-name>-winddata-timeseries-service}, e.g. https://your-name-winddata-timeseries-service.run.asw-usw02-pr.predix.io"
}
}

这两部分都正确配置之后，你的应用应该就能正确处理 ?code=xxx
