# --description--
|
||
|
||
Mount a POST handler at the path `/name`. It’s the same path as before. We have prepared a form in the html frontpage. It will submit the same data of exercise 10 (Query string). If the body-parser is configured correctly, you should find the parameters in the object `req.body`. Have a look at the usual library example:
|
||
|
||
<blockquote>route: POST '/library'<br>urlencoded_body: userId=546&bookId=6754 <br>req.body: {userId: '546', bookId: '6754'}</blockquote>
|
||
|
||
Respond with the same JSON object as before: `{name: 'firstname lastname'}`. Test if your endpoint works using the html form we provided in the app frontpage.
|
||
|
||
Tip: There are several other http methods other than GET and POST. And by convention there is a correspondence between the http verb, and the operation you are going to execute on the server. The conventional mapping is:
|
||
|
||
POST (sometimes PUT) - Create a new resource using the information sent with the request,
|
||
|
||
GET - Read an existing resource without modifying it,
|
||
|
||
PUT or PATCH (sometimes POST) - Update a resource using the data sent,
|
||
|
||
DELETE => Delete a resource.
|
||
|
||
There are also a couple of other methods which are used to negotiate a connection with the server. Except from GET, all the other methods listed above can have a payload (i.e. the data into the request body). The body-parser middleware works with these methods as well.

# --hints--
|
||
|
||
Test 1 : Your API endpoint should respond with the correct name
|
||
|
||
```js
|
||
(getUserInput) =>
|
||
$.post(getUserInput('url') + '/name', { first: 'Mick', last: 'Jagger' }).then(
|
||
(data) => {
|
||
assert.equal(
|
||
data.name,
|
||
'Mick Jagger',
|
||
'Test 1: "POST /name" route does not behave as expected'
|
||
);
|
||
},
|
||
(xhr) => {
|
||
throw new Error(xhr.responseText);
|
||
}
|
||
);
|
||
```
|
||
|
||
Test 2 : Your API endpoint should respond with the correct name
|
||
|
||
```js
|
||
(getUserInput) =>
|
||
$.post(getUserInput('url') + '/name', {
|
||
first: 'Keith',
|
||
last: 'Richards'
|
||
}).then(
|
||
(data) => {
|
||
assert.equal(
|
||
data.name,
|
||
'Keith Richards',
|
||
'Test 2: "POST /name" route does not behave as expected'
|
||
);
|
||
},
|
||
(xhr) => {
|
||
throw new Error(xhr.responseText);
|
||
}
|
||
);
|
||
```
