Question

Axios没有捕获到“电子邮件重复条目”错误。我的axios函数在动作创建器（redux）中，该创建器将帖子发送到我的快速服务器。这是电话

axios.post(api + '/api/register', { user })
  .then(res => {
      dispatch(success(user));
      dispatch({ type: ADD_USER, payload: res.data.data });
  })
  .catch(error => {
      alert('error');
      // dispatch({ type: ADD_TOAST, payload: error.response.data });
  });

我没有收到警报，也没有回应（res）？但是在我的服务器上，我控制台记录了错误，向我显示了“错误：重复输入”消息。这是错误所独有的还是我的代码中存在错误？

**使用快速文件编辑

router.post('/', function(req, res) {

  let firstname = req.body.user.firstname;
  let lastname = req.body.user.lastname;
  let email = req.body.user.email;
  let username = req.body.user.username;
  let password = req.body.user.password;

  bcrypt.hash(password, 10, function(err, hash) {
    if(err) {
        console.log('Could not hash password: ' + err);
    } else {
        // insert into users with hash then profiles
        database.query('INSERT INTO Users (ID, Firstname, Lastname, Email, Password, CreateDate) VALUES (NULL, ?, ?, ?, ?, CURRENT_TIMESTAMP)', [firstname, lastname, email, hash], function(err, result) {
            if(err) {
                console.log(err);
            } else {
                // get inserted id && insert into profiles
                let userID = result.insertId;

                database.query('INSERT INTO Profiles(ID, UserID, Photo, Bio) VALUES (NULL, ?, NULL, NULL)', [userID], function(err, result) {
                    if(err) {
                        console.log('We could not create your profile' + err);
                    } else {
                        let data = {
                            firstname: firstname,
                            lastname: lastname,
                            email: email,
                            photo: null
                        }

                        res.json({ data });
                    }
                });
            }
        });
    }
  });
});

Answer 1

您似乎必须使用

返回

axios函数中的声明

像这样：

async function register (data) {
  return axios.post(api + '/api/register', data)
  .then(res => {
    dispatch(success(user));
    dispatch({ type: ADD_USER, payload: res.data.data });
  })
  .catch(error => {
    alert('error');
    // dispatch({ type: ADD_TOAST, payload: error.response.data });
  });
}

Answer 2

在catch中从console.log（error）修改为console.log（error.response）。

axios.post('/formulas/create', {
name: "",
parts: "" }).then(response => { 
console.log(response) }) .catch(error => {console.log(error.response)});

Axios没有捕获错误
