我正在尝试找出此错误:
"error: SyntaxError: Unexpected token H in JSON at position 0 at JSON.parse (<anonymous>) at XMLHttpRequest.onLoad (http://localhost:4200/vendor.js:8646:51) at ZoneDelegate.push../node_modules/zone.js/dist/zone.js.ZoneDelegate.invokeTask (http://localhost:4200/polyfills.js:2743:31) at Object.onInvokeTask (http://localhost:4200/vendor.js:38114:33) at ZoneDelegate.push../node_modules/zone.js/dist/zone.js.ZoneDelegate.invokeTask (http://localhost:4200/polyfills.js:2742:36) at Zone.push../node_modules/zone.js/dist/zone.js.Zone.runTask (http://localhost:4200/polyfills.js:2510:47) at ZoneTask.push../node_modules/zone.js/dist/zone.js.ZoneTask.invokeTask [as invoke] (http://localhost:4200/polyfills.js:2818:34) at invokeTask (http://localhost:4200/polyfills.js:3862:14) at XMLHttpRequest.globalZoneAwareCallback (http://localhost:4200/polyfills.js:3888:17)
text: "Hello from Firebase!"
这是我的职能:
exports.helloWorld = functions.https.onRequest((req, res) => {
cors(req, res, () => {
res.send("Hello from Firebase!");
});
});
这是我对函数的调用:
public sendHttpRequestTest(){
let url = `my_link_to_functions/helloWorld`;
const req = new HttpRequest("GET",url);
this.http.request(req).toPromise()
.then( res => {
console.log(res);
})
.catch( err => {
console.log(err);
})
}
答案 0 :(得分:0)
我通过将其作为JSON发送来修复它,如下所示:
res.send(JSON.stringify("Hello from Firebase!"));
