Hi Sir:
My question is : How can I make the “Lwip package” send a valid CGI response (data type is javascript )to HTML?
additional information, I use the IWIP package on application program.
Here is my HTML, I can make sure get a response but no data after checked:
fetch("evse_para_req_high.cgi", { method: "GET" })
.then(function(response) {
console.log(response)
})
.catch(function(error) {
console.log(`Error: ${error}`);
});
Here is my C program on MCU:
static int cgi_para_req_high(HTTPSRV_CGI_REQ_STRUCT *param)
{
HTTPSRV_CGI_RES_STRUCT response = {0};
response.ses_handle = param->ses_handle;
response.status_code = HTTPSRV_CODE_OK;
response.content_length = -1;
response.content_type = HTTPSRV_CONTENT_TYPE_JS;
response.data = "console.log('Hello CGI')";
response.data_length = strlen(response.data);
HTTPSRV_cgi_write(&response);
response.data_length = 0;
HTTPSRV_cgi_write(&response);
PRINTF("CGI execution cgi_evse_para_req_high\r\n");
return (response.content_length);
}
Best Regards
Edward
