# CORS（跨來源資源共用） { #cors-cross-origin-resource-sharing }

[CORS 或「Cross-Origin Resource Sharing」](https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS)指的是：當在瀏覽器中執行的前端以 JavaScript 與後端通訊，而後端與前端位於不同「來源（origin）」時的情境。

## 來源（Origin） { #origin }

一個來源是由通訊協定（`http`、`https`）、網域（`myapp.com`、`localhost`、`localhost.tiangolo.com`）與連接埠（`80`、`443`、`8080`）三者組合而成。

因此，以下皆是不同的來源：

* `http://localhost`
* `https://localhost`
* `http://localhost:8080`
