I’m trying to implement a query of Simples Nacional, the operation is similar to the consultation by CNPJ of the recipe.
Details I’ve understood so far:
- After loading the page, runs a
ajax(filing cabinetcaptcha2.js) which returns 3 items in formatJSON {Token, Dados, ContentType}. TheTokenis stored in a cookie which would probably serve to validate the image after Ubmit.Dadosis the Base64 of the image.ContentTypethe type of the image. - It generates the cnpj input by concatenating a number that is also stored in another Hidden input (id:
ctl00_ContentPlaceHolderConteudo_HiddenField1). - There are other inputs (__VIEWSTATE, __EVENTVALIDATION, __EVENTARGUMENT, __EVENTTARGET) that store values, the last two, usually empty...
I am capturing the initial data and setting the headers in the second request to recover the data, however, the problem is that it always gives error (Invalid anti-toba characters. Try again.).
Follow the codes I have so far (may be messy or with unnecessary lines, are just tests yet, still need to clear the code later):
Consultacnpjsimplesnacional.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);

Note that, the current structure is mounted in the framework Yii2 (I did not find it necessary to include her as a tag), but she can be easily "disassembled" to implement anywhere else, whereas the "heart" is the class Consultacnpjsimplesnacional.
Someone has already had to implement a query for Simple National, or could indicate some way of why not validate the images (captcha) ?
Link to the PHP Simple Html DOM Parser used in class to "defragment" html and take the values of fields.
