Using HTTP POST Multipart/Form-Data to Upload SQLite Databases to a PHP Server
This guide details how to upload an SQLite database file to a PHP server using an HTTP POST request with the multipart/form-data content type, including a "userid" string parameter.
Steps:
First, initialize a cURL session:
CURL *curl = curl_easy_init();
Next, set the request URL and specify the POST method:
curl_easy_setopt(curl, CURLOPT_URL, "http://www.myserver.com/upload.php"); curl_easy_setopt(curl, CURLOPT_POST, 1);
Now, construct the multipart/form-data structure:
curl_mime *mime = curl_mime_init(curl); curl_mimepart *part = curl_mime_addpart(mime);
Set the database file data:
curl_mime_data(part, fileBytes, fileBytesLength);
Specify the file name and MIME type:
curl_mime_name(part, "userfile"); curl_mime_type(part, "application/octet-stream");
Include the "userid" parameter:
curl_mimepart *part2 = curl_mime_addpart(mime); curl_mime_data(part2, "userid=SOME_ID", strlen("userid=SOME_ID"));
Attach the multipart data to the cURL request:
curl_easy_setopt(curl, CURLOPT_MIMEPOST, mime);
Finally, execute the request and handle the response:
CURLcode response_code = curl_easy_perform(curl); if (response_code != CURLE_OK) { // Handle cURL errors }
Important Considerations:
upload.php
