Submit a form using POST request in VueJS
提问by Dinesh Ahuja
I have an endpoint to submit data using POST request,
我有一个端点可以使用 POST 请求提交数据，
http://localhost:3000/entry
Keys are fname, lname, age
键是 fname, lname, age
I can make a POST request into the given end point and it will create an entry.
我可以向给定的端点发出 POST 请求，它会创建一个条目。
I am trying to submit a form using VueJS. But, when I am calling the API within the form, it is not submitting the data. I have checked the network calls and it is not sending any data to the end point.
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。

You can try this one.
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 => {});
Before using you need to link with Axios CDN
使用前需要链接Axios CDN

Maybe something like this
也许像这样
this.$http({method: 'POST', url: URL, data: data})
.then(response => {
this.postResults = data;
this.ajaxRequest = false;
}).catch((err) => {
console.log(err)
})
