reactjs axios post请求抛出错误

Question

我有一个函数可以在提交表单时从表单中获取数据，我正在尝试使用带有此数据的 axios 进行发布请求，这是我的函数 (reactjs)：

const handelSubmit = (e) => {
        e.preventDefault();
        const newFact = {Email, Fact, Source};
        axios.post('https://www.examplesite.com/create', {
          "data": newFact})
          .then(function (response) {
            console.log(response);
          })
    }

这是示例站点 (nodejs) 的部分代码：

const app = express();
app.use(express.json());

app.use(function(req, res, next) {
    res.header('Access-Control-Allow-Origin', '*');
    res.header('Access-Control-Allow-Headers', 'Origin, X-Requested-With, Content-Type, 
Accept');
    next();
});

app.get("/", async function(req, res) {
    const result = await randomfact();
    res.send(result);
    console.log(randomfact());
});

app.post('/create', function(req, res) {
  console.log(req.body);
});

let port = process.env.PORT;
if(port == null || port == "") {
   port = 8000;
}

app.listen(port, function() {
   console.log("Server started successfully");
});

我的问题是帖子请求似乎没有发送到示例站点，这是我得到的错误：
