Topic: Getting the content of a request GET XXX Host:XXX Content...

[guillaume.chevet]

Hello,

I'm develloping a web-service as an apache module in C. I'm trying to test it with telnet but i don't know how I kann access some information.

I open telnet (telnet localhost 80) and paste the following text:
"
GET /MYTEST
HTTP/1.1
Host: myhost.test.de:8180
Accept: */*
Accept-Encoding: deflate, gzip
Content-type:text/plain; charset=utf-8
Content-Length: 29

address=mytest@kunde.de
"

How kann I access all these information with the request_rec object?

Thanks a lot,
Guillaume

A very simple and short module is mod_echo. It does what the name says it simply echos what you send to it. So I think it can be a good start for to look into that module.

http://svn.apache.org/repos/asf/httpd/httpd/branches/2.2.x/modules/echo/mod_echo.c

Thank a lot!

I found 2 way to read the headers. With the first way I cant read the body:

/* Functions to Write the HEADER_IN CONTENT
* Call dump_request(r);
*/
int iterate_func(void *req, const char *key, const char *value) {
fprintf(stderr,"iterate_func :\n");
int stat;
char *line;
request_rec *r = (request_rec *)req;
if (key == NULL || value == NULL || value[0] == '\0')
return 1;
fprintf(stderr, "%s => %s\n", key, value);
fflush(stderr);

return 1;
}

static int dump_request(request_rec *r) {
fprintf(stderr,"dump_request :\n");

ap_set_content_type(r, "text/plain");

if (apr_is_empty_table(r->headers_in))
{
fprintf(stderr,"EMPTY");
fflush(stderr);
}



apr_table_do(iterate_func, r, r->headers_in, NULL);
fprintf(stderr,"dump_request :\n");

return OK;
}

------------The second way-----------------
static int mod_mymethod_handler(conn_rec *c)
{
apr_bucket_brigade *brigade = NULL;
apr_bucket *bucket = NULL;
int seen_eos = 0;
int seen_body = 0;

apr_status_t rc;

//Initialize the brigade object
brigade = apr_brigade_create(c->pool, c->bucket_alloc);

do //for each line of the request
{
// Get the input from the client
if (((rc = ap_get_brigade(c->input_filters, brigade, AP_MODE_GETLINE, APR_BLOCK_READ, 0)) != APR_SUCCESS) || APR_BRIGADE_EMPTY(brigade))
{
apr_brigade_destroy(brigade);
break;
}

//For each element (buckets) from the input (brigade)
for (bucket = APR_BRIGADE_FIRST(brigade); bucket != APR_BRIGADE_SENTINEL(brigade); bucket = APR_BUCKET_NEXT(bucket))
{
char *data;
apr_size_t len;
int i;

if (APR_BUCKET_IS_EOS(bucket))
{
seen_eos = 1;
break;
}

rc = apr_bucket_read(bucket, &data, &len, APR_BLOCK_READ);

if (rc != APR_SUCCESS)
{
break;
}

//Parse the data
char *position = strchr(data, '\n');
int length = strlen(data)-strlen(position);
char *result = (char *)malloc((length+1)*sizeof(char));

strncpy(result, data, length);

result[length] = '\0';

fprintf(stderr,"\n gefunden = %s \n", result);
fflush(stderr);
free(result);


}

apr_brigade_cleanup(brigade);

} while (!seen_eos); //Wait for the end of the request

apr_brigade_destroy(brigade);
