我正在爲一個簡單的NodeJS應用程序編寫單元測試,並且出於某種原因,我無法檢索響應正文。它會得到正確的響應代碼(對於成功的請求或者是200,對於無效的請求是422),但是主體看起來是空的。此外,當我與http12完全相同的請求,它的作品就像魅力。日誌記錄還顯示控制器按預期工作。node-fetch收到空體
歡迎任何想法或建議。
這裏的控制器部分:
function register (req, res) {
return _findUser({email: req.body.email})
.then(user => {
if (user) {
console.log('EMAIL TAKEN');
return Promise.reject({message: 'This email is already taken'});
}
let params = _filterParams(req.body);
if (_isRegistrationValid(params)) {
console.log('REGISTRATION VALID');
return params;
} else {
console.log('PARAMS INVALID');
return Promise.reject({message: 'Params invalid'});
}
})
.then(_createUser)
.then(_generateToken)
.then(token => {
console.log('SENDING TOKEN');
console.log(token);
res.send({token: token});
})
.catch(error => {
console.log('CATCH ERROR');
res.status(422).send(error);
});
}
這裏的測試部分:
it ('Returns token when data is valid', done => {
fetch(`http://localhost:${testPort}/api/register`, {
headers: {'Content-Type': 'application/json'},
method: 'POST',
body: JSON.stringify({email: '[email protected]', password: 'password', confirmPassword: 'password'})
})
.then(response => {
assert(response.ok); // this part works ok
expect(response.body.token).to.exist; // this part fails
done();
})
.catch(done);
});
這裏的httpie輸出:
kpr$ http post localhost:4000/api/register email="[email protected]" password="password" confirmPassword="password"
HTTP/1.1 200 OK
Connection: keep-alive
Content-Length: 941
Content-Type: application/json; charset=utf-8

{
"token": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9_long_token_string_2M"
}
下面是測試輸出:

1) Authorization Registration Returns token when data is valid:

打印出響應的身體從內取()顯示了一些巨大的對象:
PassThrough {
_readableState:
ReadableState {etc...}
}
你可以嘗試'response.json()'而不是'response.ok'嗎? –
response.json()返回_Promise {} _ –

好吧,我認爲這就是我需要的: _response.json()。然後()_返回我需要的。 非常感謝,大衛! – Konstantin
