I'm trying to serve multiple files with Echo, but it doesn't work every time. The api code looks like this:
package main
import (
"github.com/labstack/echo"
"net/http"
)
func main() {
e := echo.New();
e.GET("/", home);
e.File("/data1", "assets/data1.csv");
e.File("/data2", "assets/data2.csv");
e.Logger.Fatal(e.Start(":4243"));
}
func home(c echo.Context) error {
return c.String(http.StatusOK, "Are you lost?");
}
To be precise, it does work for the very first file fetching, but then keeps failing for any subsequent calls (be them file fetching or more "classic" calls). The error message is a tad different for each browser:
In Chrome:
SyntaxError: Failed to execute 'setRequestHeader' on 'XMLHttpRequest': 'Bearer {the_entire_content_of_the_first_fetched_file}' is not a valid HTTP header field value.
In Firefox:
SyntaxError: An invalid or illegal string was specified
In Edge, simply:
SyntaxError
Tried activating CORS, nothing changed.
Looks to work pretty well with Postman. Maybe it's a problem with how I do fetch my data in my application?
If you need perhaps a bit more information, this thread is directly related to my previous one (Vuejs with axios request in vuex store: can't make more than one request, why?), but I didn't want to mix them up, as I don't know yet if I'm mistaken in my Vue code or my Echo one...
