Let’s talk about how vue transfers objects to the background

Vue is a very powerful front-end framework that provides many convenient methods of sending requests to interact with the background. In Vue, we can use request libraries such as Ajax or axios to send requests to the background. When sending a request to the background, we usually pass some data, which we also call parameters in the background. In Vue, we have many ways to send parameters. We can wrap it into an object and send it to the background, or we can directly split it and send it to the background in turn.

If we want to pass an object to the background, we can use JavaScript's JSON.stringify method to convert the object into a string in JSON format, and then send it to the background through libraries such as Ajax or axios. For example, if we have an object named article, we can use the following code to convert it into a JSON format string and then send it to the background.

let article = {
  title: 'Vue怎么把对象传到后台',
  content: '在Vue中，我们可以使用Ajax或者axios等等请求库来向后台发送请求，当向后台发送请求的时候，我们通常会传递一些数据，在后台我们也称之为参数。而在Vue中，我们发送参数的方式有很多，可以将其包装成一个对象，然后发送给后台，也可以直接将其拆分开来，依次发送给后台。'
}
let jsonData = JSON.stringify(article)

In the above example, we converted the article object into a json format string using the JSON.stringify method, and stored the converted string in the jsonData variable.

Next we can use libraries such as Ajax or axios to send requests to the background. When sending, we need to send the JSON format string as a parameter to the background.

axios.post('/post_url', jsonData, {
  headers:{
    'Content-Type': 'application/json;charset=UTF-8'
  }
}).then(res => {
  console.log(res)
}).catch(err=>{
  console.log(err)
})

In the above code, we use the post method of axios to send a request to the background. The second parameter jsonData is the json format string we get after converting the article object. In the request header, we need to specify Content-Type as application/json;charset=UTF-8. This parameter indicates that the type of data we send is in json format. In this way, our article object can be successfully sent to the background.

In addition to using JSON.stringify to convert objects into JSON format strings, we can also directly send objects to the background.

axios.post('/post_url',{
  title: 'Vue怎么把对象传到后台',
  content: '在Vue中，我们可以使用Ajax或者axios等等请求库来向后台发送请求，当向后台发送请求的时候，我们通常会传递一些数据，在后台我们也称之为参数。而在Vue中，我们发送参数的方式有很多，可以将其包装成一个对象，然后发送给后台，也可以直接将其拆分开来，依次发送给后台。'
},{
  headers:{
    'Content-Type': 'application/json;charset=UTF-8'
  }
}).then(res => {
  console.log(res)
}).catch(err=>{
  console.log(err)
})

In the above code, we can directly transfer the content of the article object, but we need to pay attention to specifying the Content-Type as application/json;charset=UTF-8 when sending the request. item.

In short, no matter which way, we can successfully pass an object to the background. Of course, in actual development, we also need to combine the background interface documents to achieve data transfer. Finally, I wish everyone can successfully transfer data to the backend during development using Vue!
