从file_get_contents转换为wp_remote_get

Question

I'm having some trouble converting this function from file_get_contents to wp_remote_get and I was hoping for some insight. This seems like I'm so close. Below are two cases, my original which works using file_get_contents, and the second which does the same thing but uses wp_remote_get and doesn't work. Can anyone help me figure out what I'm screwing up?

    case 'one':
        $url = "https://api.bitfinex.com/v1/pubticker/btcusd";
        $json = json_decode(file_get_contents($url), true);
        $price = $json["last_price"];
        return $price;
        break;
    case 'two':
        $request = wp_remote_get( 'https://api.bitfinex.com/v1/pubticker/btcusd' );
    if( is_wp_error( $request ) ) {
        return false;
    }
        $body = wp_remote_retrieve_body( $request );
        $data = json_decode( $body );
        if( ! empty( $data ) ) {

            foreach( $data['last_price'] as $price ) {
                return $price;
            }
        }
        break;

Answer 1

When I view the decoded json, if looks like $data['last_price'] is not an array. So maybe what you want is:

This:

foreach( $data['last_price'] as $price ) {
     return $price;
}

Could just be:

return $data['last_price'];

Because the returned json object is just one array of what looks to be financial data. That is also how you have it in your first example.
