I am using Postman to test my function and am using POST to send the request. Every time I send it, I get the error: 'Cannot POST /translate'. I added the code below for my route and function:
app.post('/translate'), async function(request, response) {
const translatedText = await translateText(request)
res.json(translatedText)
}
async function translateText(request) {
const text = request.body['text']
const language = request.body['language']
let [translations] = await translate.translate(text, language)
translations = Array.isArray(translations) ? translations : [translations]
return translations
}
You've misused the app.post method. First you create the url, as you have done, but then it requires a callback method inside the method parameters.
// remove ) after '/translate'
app.post('/translate', async function(request, response) {
const translatedText = await translateText(request)
res.json(translatedText)
});
from the express docs:
Route definition takes the following structure:
app.METHOD(PATH, HANDLER)Where:
- app is an instance of express.
- METHOD is an HTTP request method, in lowercase.
- PATH is a path on the server.
- HANDLER is the function executed when the route is matched.
