Hello,
on 02/21/2006 03:40 PM Dirk Vanden Boer said the following:
I have a C++ application that posts binary data to a php script that I
created using libcurl. Everything works fine except when my binary data
happens to start with the '&' symbol. In that case I can't read the http
post data (isset returns false).
The post argument then looks like data=&ÑÚA
Reading the post is done like this:
if (isset($_POST['data'])
Is there a way to fix this problem?
The problem is that you are misleading PHP telling that you are posting
form data. You need to correct the request Content-Type. It must not be
application/x-www-form-urlencoded nor multipart/form-data . I think you
can use anything except those types, like for instance
application/octet-stream which is the default for binary files.
I don't know how can you hack libcurl to make it use the right request
content-type. It is probably easy. If you are not able to do it, you may
want to try this PHP HTTP client class . It can send custom POST requests.

You are correct, setting the headers is necessary but I was already
doing that, curl supports it by calling
struct curl_slist *headers=NULL;
headers = curl_slist_append(headers, "Content-Type: text/xml");
curl_easy_setopt(easyhandle, CURLOPT_HTTPHEADER, headers);
I have everything working at the moment by base64 encoding my data and
then doing a urlencode. One pitfall I noticed: do not urlencode the post
argument, only the data, eg:
data=JtVLV43XWl...
urlencoded
data%3DJtVLV...
This doesn't work, so I just urlencoded my base64 data, and prepended
the data= string.
Thanks for all your help guys from this thread ;)
Cheers,
Dirk
