我也遇到了这个问题,发现自己在这个 S.O.线。我尝试按照上面 Frank van Puffelen 的建议进行操作。
在functions/.runtimeconfig.json:
{
"algolia": {
"appid": "ID",
"apikey": "KEY"
},
"webmerge": {
"key": "KEY",
"secret": "SECRET",
"stashkey": "STASH_KEY"
},
}
在functions/index.ts:
import * as functions from 'firebase-functions';
import * as admin from 'firebase-admin';
. . .
const cors = require('cors')({origin: true})
const envObj = functions.config()
. . .
export const getEnv = functions.https.onRequest((req, resp) => {
cors(req, resp, () => resp.status(200).send(JSON.stringify(envObj)));
});
. . .
注意:在本地工作时,我使用 cors 包来解决 CORS 错误。当localhost:5000(模拟器托管)调用localhost:5001(模拟器功能)时,我会收到这些错误。
在web_flutter/main.dart:
Future<Map<String, dynamic>> fetchEnv(String functionsURL) async {
var response = await http.get('${functionsURL}/getEnv');
return json.decode(response.body);
}
Future<void> main() async {
try {
var functionsURL = 'FUNCTIONS_URL';
var app = fb.initializeApp(firebase app details);
if (window.location.hostname == 'localhost') {
app.firestore().settings(Settings(
host: 'localhost:8080',
ssl: false,
));
functionsURL = 'http://localhost:5001';
}
var env = await fetchEnv(functionsURL);
var searchClient = Algolia.init(
applicationId: env['algolia']['appid'],
apiKey: env['algolia']['apikey']);
runApp(MyApp(
repository: Repository(app.firestore(), searchClient),
authentication: Authentication(app.auth())));
} on fb.FirebaseJsNotLoadedException catch (e) {
print(e);
}
}
一旦我确认这在本地工作,我就可以使用 firebase functions:config:set 在实时函数环境中设置这些数据,并使用 firebase deploy 部署我更新的托管和函数。
