当运行我的应用程序的生产版本时，res.data返回html而不是令牌

如何解决当运行我的应用程序的生产版本时，res.data返回html而不是令牌

当我在本地计算机上运行开发版本时，res.data将在登录时返回用户的JWT令牌。但是，当我在VPS上运行生产版本时，res.data返回此HTML。：

Users.js：

router.post("/register",(req,res) => {
  // Form validation

  const { errors,isValid } = validateRegisterInput(req.body);

  // Check validation
  if (!isValid) {
    return res.status(400).json(errors);
  }

  User.findOne({ name: req.body.name.toLowerCase() }).then(user => {
    if (user) {
      return res.status(400).json({ name: "Name already exists" });
    } else {
      const newUser = new User({
        name: req.body.name.toLowerCase(),password: req.body.password
      });

      // Hash password before saving in database
      bcrypt.genSalt(10,(err,salt) => {
        bcrypt.hash(newUser.password,salt,hash) => {
          if (err) throw err;
          newUser.password = hash;
          newUser
            .save()
            .then(user => res.json(user))
            .catch(err => console.log(err));
        });
      });
    }
  });
});

// @route POST api/users/login
// @desc Login user and return JWT token
// @access Public
router.post("/login",isValid } = validateLoginInput(req.body);

  // Check validation
  if (!isValid) {
    return res.status(400).json(errors);
  }

  const name = req.body.name.toLowerCase();
  const password = req.body.password;

  // Find user by name
  User.findOne({ name }).then(user => {
    // Check if user exists
    if (!user) {
      return res.status(404).json({ namenotfound: "Name not found" });
    }
    if (user.name === "admin") {
      return res.status(404).json({ namenotfound: "Name not found" });
    }

    // Check password
    bcrypt.compare(password,user.password).then(isMatch => {
      if (isMatch) {
        // User matched
        // Create JWT Payload
        const payload = {
          id: user.id,name: user.name
        };

        // Sign token
        jwt.sign(
          payload,keys.secretorKey,{
            expiresIn: 31556926 // 1 year in seconds
          },token) => {
            res.json({
              success: true,token: "Bearer " + token
            });
          }
        );
      } else {
        return res
          .status(400)
          .json({ passwordincorrect: "Password incorrect" });
      }
    });
  });
});

authActions.js

export const loginUser = userData => dispatch => {
  axios
    .post("/api/users/login",userData)
    .then(res => {
      // Save to localStorage

      // Set token to localStorage
      console.log(res.data)
      console.log(res.data.token)
      const { token } = res.data;
      localStorage.setItem("jwtToken",token);
      // Set token to Auth header
      setAuthToken(token);
      // Decode token to get user data
      const decoded = jwt_decode(token);
      // Set current user
      dispatch(setCurrentUser(decoded));
    })
    .catch(err =>
      dispatch({
        type: GET_ERRORS,payload: ((err||{}).response||{}).data || 'Error unexpected'
      })
    );
};

这将使localStorage中的JWT令牌未定义，并完全阻止我的应用注册用户，登录用户等。

有什么办法解决这个问题？

（要构建我的项目，我一直在运行react-scripts build，然后使用serve -s build -l 80将其托管在端口80上）

解决方法

我发现了问题所在。我没有提供使用react-scripts build创建的静态文件。

app.use(express.static('client/build'))

app.get('*',(req,res) => {
   res.sendFile(path.resolve(__dirname,'client','build','index.html'))
})
