I'm trying to implement a query of Simple Nacional , the operation is similar to the query by CNPJ of the revenue.
Details I've seen so far:
ajax ( file captcha2.js ) that returns 3 items in JSON {Token, Dados, ContentType} format. Token is stored in a cookie that would probably serve to validate the image after submit. Dados is the base64 of the image. ContentType the type of the image. ctl00_ContentPlaceHolderConteudo_HiddenField1 ). I am capturing the initial data and setting the headers on the second request to retrieve the data, however, the problem is that it always gives error ( Invalid robot characters, please try again.)
Here are the codes I have so far (they may be messy or have unnecessary lines, they are only tests yet, the code has to be cleaned later):
SimpleChangeInfo.php:
class ConsultaCnpjSimplesNacional
{
/**
* Devolve um array de parâmetros para consulta de CNPJ Simples Nacional
* @return array
*/
public static function getParams()
{
$ckfile = tempnam("/tmp", "CURLCOOKIE");
// ini_set('xdebug.var_display_max_depth', 5);
// ini_set('xdebug.var_display_max_children', 256);
// ini_set('xdebug.var_display_max_data', 10000000000000);

Please note that the current framework is mounted in the Yii2 framework (I did not find it necessary to include it as a tag), but it can be easily "disassembled" to implement anywhere else, since the "heart" is the class NationalContextInfo .
Has anyone ever had to implement a query for the National Simple, or could it indicate some path of the reason for not validating the images (captcha)?
Link to the PHP Simple Html DOM Parser used in class to "defragment" the html and get the values of the fields.
