How to correctly use axios params with arrays
When using for API calls, you may need to send array-type parameters to the server. Proper handling of array-type parameters depends on how the server parses the parameters. Generally, there are several ways to submit array-type parameters:1. Passing Arrays via Query StringsYou can convert the array into a query string format, for example:In Axios, you can simply pass the array directly as a parameter, and Axios will automatically serialize it into a query string:Axios will serialize the request to .2. Customizing Serialization withIf you need to customize how the array is serialized into a query string, you can use the function. For example, if you want to use a comma-separated array:This will serialize the request to .3. Sending Arrays as JSON in POST RequestsIf you are sending a request and need to include the array in the request body, you can send the array as a JSON object:This way, the array is sent as part of the JSON payload to the server.ExampleSuppose there is an API endpoint that receives an array-type parameter to filter search results. Using the query string approach, you can call the API as follows:If the server expects a comma-separated string instead of multiple identical keys, you can use the to customize the serialization:The above methods are common approaches for handling array-type parameters. The specific method to use depends on the expected format of the backend API, so in practice, you should select the appropriate array serialization method based on the server's requirements.
