Axios: Get parameter array with key value

[ghprod]

Hi,

I've searching, but can't find the way to do it. Basically i want to send GET request with array parameter like this

GET /comments?filter[post]=3&filter[author]=12

I've tried this

params: {
  filter: {post: 3, author: 12}
}

But still no luck :(

Any hint?

Thanks

Hi @ghprod, first of all I want to make clear that I'm not a contributor to this library nor I use it, but I was passing by and I saw this issue and decided to investigate the code a bit.

Axios does not support that kind of encoding by default but it allows you to provide a custom serializer. You can accomplish this very easily with the following code:

// Axios include here...

axios.get('/user', {
    params: {
        filter: {post: 3, author: 12} 
    },
    paramsSerializer: customSerializerFunc
});

To make it simpler, I googled a bit for querystring serializer libraries and found qs which has support for browsers and nodejs. You can use it as a serializer this way:

// Include axios and qs here...

axios.get('/user', {
    params: {
        filter: {post: 3, author: 12} 
    },
    paramsSerializer: qs.stringify  // If this doesnt work, append .bind(qs) to the end of this line.
});

Maybe you'll see this: filter%5Bpost%5D=3 instead of filter[post]=3, that's because URL encoding is enabled. You can disable it this way:

axios.get('/user', {
    params: {
        filter: {post: 3, author: 12} 
    },
    paramsSerializer: function(params) {
        return qs.stringify(params, { encode: false });
    }
});

Let me know if it worked.
