Specification
Hi,
I have an EA that is feed with a file wich need to be extracted from internet every day from a web site. To do this mannualy I need to click on a button in this site and the file is downloaded (picture bellow), but I would like to do this automatically, Using WebRequest() The file must be downloaded on actual date of the form to "File" folder and then unziped there overwirting the older file.

You can use the code bellow as example, it works but the date of the form is fixed, you need put always the actual date
Use Chrome to inspect, the execution and debug what happens
oid OnStart() { string cookie=NULL,headers; char post[],result[]; string url="http://www.b3.com.br/lumis/portal/file/fileDownload.jsp?fileId=8AE490C96A051101016A0596E52F6182"; //--- para trabalhar com o servidor é necessário adicionar a URL "https://finance.yahoo.com" //--- na lista de URLs permitidas (menu Principal->Ferramentas->Opções, guia "Experts"): //--- redefinimos o código do último erro ResetLastError(); //--- download da página html do Yahoo Finance int res=WebRequest("GET",url,cookie,NULL,500,post,0,result,headers); if(res==-1) { Print("Erro no WebRequest. Código de erro =",GetLastError()); //--- é possível que a URL não esteja na lista, exibimos uma mensagem sobre a necessidade de adicioná-la MessageBox("É necessário adicionar um endereço '"+url+"' à lista de URL permitidas na guia 'Experts'","Erro",MB_ICONINFORMATION); } else { if(res==200) { //--- download bem-sucedido PrintFormat("O arquivo foi baixado com sucesso, tamanho %d bytes.",ArraySize(result)); //PrintFormat("Cabeçalhos do servidor: %s",headers); //--- salvamos os dados em um arquivo int filehandle=FileOpen("url.zip",FILE_WRITE|FILE_BIN); if(filehandle!=INVALID_HANDLE) { //--- armazenamos o conteúdo do array result[] no arquivo FileWriteArray(filehandle,result,0,ArraySize(result)); //--- fechamos o arquivo FileClose(filehandle); } else Print("Erro em FileOpen.
