javascript - 在 VueJS 中使用 POST 请求提交表单

Question

我有一个使用 POST 请求提交数据的端点，

http://localhost:3000/entry

键是 fname, lname, age
我可以向给定的端点发出 POST 请求，它将创建一个条目。

我正在尝试使用 VueJS 提交表单。但是，当我在表单中调用 API 时，它并没有提交数据。我检查了网络调用，它没有向端点发送任何数据。

你可以试试这个。

axios.post('http://localhost:3000/entry',{ params: { fname: this.fname, lname: this.lname, age: this.age }})
.then(response => this.responseData = response.data)
.catch(error => {});
