英文:
Problems opening an endpoint for the front-end to fetch
问题
BACKEND CODE
app.get("/ranking", (req, res) => {
res.render("ranking");
})
app.get("registros", () => {
db.all("SELECT * FROM resultados", (err, rows) => {
if (err) {
console.error(err.message);
return;
}
console.log(rows);
return rows;
});
})
FRONTEND CODE
function traerRegistrosDB() {
fetch("/registros")
.then(res => res.json())
.then(res => res)
.catch(() => {
console.error("registros innacesibles")
})
};
ERROR
http://localhost:3000/registros 404 (Not Found)
-I tried doing a console.log() in the back. It didn't show up
-Adding headers
-Going directly to the direction local..../registros
英文:
As said in the title, I'm writing a aplication in Node.Js and I need it to return a JSON (or at least console.log() the data, I can figure out the rest) I it seems like the URL doesn't exist
BACKEND CODE
app.get("/ranking",(req,res)=>{
res.render("ranking");
})
app.get("registros",()=>{
db.all("SELECT * FROM resultados", (err, rows) => {
if (err) {
console.error(err.message);
return;
}
console.log(rows);
return rows;
});
})
FRONTEND CODE
function traerRegistrosDB(){
fetch("/registros")
.then(res=>res.json())
.then(res => res)
.catch(()=>{
console.error("registros innacesibles")
})
};
ERROR
http://localhost:3000/registros 404 (Not Found)

app.get("registros" 应该改为 app.get("/registros"
英文:
You miss a slash :
app.get("registros" should be app.get("/registros"

由于后端和前端地址不同，使用fetch时需要输入完整地址。
我分享以下示例。
假设后端地址为http://localhost:8080。
function traerRegistrosDB(){
fetch("http://localhost:8080/registros")
.then(res=>res.json())
.then(res => res)
.catch(()=>{
console.error("registros innacesibles")
})
};
英文:
Since the backend and frontend addresses are different, you need to enter the full address when using fetch.
I am sharing the example below.
Suppose the backend address is http://localhost:8080.
function traerRegistrosDB(){
fetch("http://localhost:8080/registros")
.then(res=>res.json())
.then(res => res)
.catch(()=>{
console.error("registros innacesibles")
})
};
