How to convert Vue request parameters into json format

In Vue development, we often need to obtain server-side data through Ajax requests. When passing parameters, we will construct the parameters as an object or array. This object or array is the request parameter when we initiate the request.

But in Vue development, we often encounter a problem: we cannot directly pass a complex object or array as a request parameter, because when sending an Ajax request, the request parameter must be a character in json format string.

So, how do we convert Vue's request parameters into json format?

First, let’s take a look at the request parameter object in Vue:

const params = {
  name: 'John',
  age: 25,
  interests: ['football', 'basketball'],
  address: {
    province: 'Guangdong',
    city: 'Guangzhou'
  }
}

In the above code, we define a params object as a request parameter, which contains basic data types and complex data types.

We need to convert this params object into a json format string, which can be achieved through the following code:

const jsonParams = JSON.stringify(params)

In the above code, we use the JSON.stringify() method to convert the params object A string in json format.

Then let’s take a look at the request parameter array in Vue:

const params = [
  { name: 'John', age: 25 },
  { name: 'Mike', age: 23 },
  { name: 'Lily', age: 21 }
]

In the above code, we define a params array as the request parameter, in which each element is an object.

Similarly, we need to convert this params array into a json format string, which can be achieved through the following code:

const jsonParams = JSON.stringify(params)

In the above code, we also use the JSON.stringify() method to convert The params array is converted into a string in json format.

To summarize, whether we pass request parameter objects or arrays in Vue, we can convert them into json format strings through the JSON.stringify() method.

It should be noted that the JSON.stringify() method also has some precautions:

1. If the object contains special values ​​such as functions and undefined, it will be stringified after Ignored;
2. If there is a circular reference in the array, an error will be reported after stringification.
