Php 使用POST上传带有curl的文件,但模拟HTML提交
我有以下C代码:Php 使用POST上传带有curl的文件,但模拟HTML提交,php,c,post,curl,libcurl,Php,C,Post,Curl,Libcurl,我有以下C代码: int main(int argc, char* argv[]) { CURL *curl; CURLcode res; struct stat file_info; double speed_upload, total_time; FILE *fd; fd = fopen(argv[1], "rb"); /* open file to upload */ if(!fd) { return 1; /* can't continue */
int main(int argc, char* argv[])
{
CURL *curl;
CURLcode res;
struct stat file_info;
double speed_upload, total_time;
FILE *fd;
fd = fopen(argv[1], "rb"); /* open file to upload */
if(!fd) {
return 1; /* can't continue */
}
/* to get the file size */
if(fstat(fileno(fd), &file_info) != 0) {
return 1; /* can't continue */
}
curl = curl_easy_init();
if(curl) {
/* upload to this place */
curl_easy_setopt(curl, CURLOPT_URL,
"http://www.website.com/index.php");
/* tell it to "upload" to the URL */
curl_easy_setopt(curl, CURLOPT_POST, 1L);
/* set where to read from (on Windows you need to use READFUNCTION too) */
curl_easy_setopt(curl, CURLOPT_READDATA, fd);
/* and give the size of the upload (optional) */
curl_easy_setopt(curl, CURLOPT_INFILESIZE_LARGE,
(curl_off_t)file_info.st_size);
/* enable verbose for easier tracing */
curl_easy_setopt(curl, CURLOPT_VERBOSE, 1L);
res = curl_easy_perform(curl);
/* Check for errors */
if(res != CURLE_OK) {
fprintf(stderr, "curl_easy_perform() failed: %s\n",
curl_easy_strerror(res));
}
else {
/* now extract transfer info */
curl_easy_getinfo(curl, CURLINFO_SPEED_UPLOAD, &speed_upload);
curl_easy_getinfo(curl, CURLINFO_TOTAL_TIME, &total_time);
fprintf(stderr, "Speed: %.3f bytes/sec during %.3f seconds\n",
speed_upload, total_time);
}
/* always cleanup */
curl_easy_cleanup(curl);
}
return 0;
}
以及以下PHP代码:
<?php
header('Access-Control-Allow-Origin: *');
if ($_SERVER['REQUEST_METHOD'] == 'POST' )
{
if( isset( $_FILES["file_entry"] ) )
{
print "file ok";
}
else
{
print "no file sent";
}
}
else
{
print "No post method" . $_SERVER['REQUEST_METHOD'];
}
?>
和html代码:
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title></title>
</head>
<body>
<form action="index.php" enctype="multipart/form-data" method="post">
<input type="file" name="file_entry"/>
<input type="submit" value="enviar"/>
</form>
</body>
</html>
如果我尝试通过html发送文件,它可以正常工作,但在使用C和cURL时就不行了。
因为我不知道如何发送“文件输入”。如何像html那样用C cURL模拟提交“文件\条目”?我尝试使用CURLOPT_POSTFIELDS,但不起作用
有人能帮我吗
谢谢这是因为您的服务器端需要“多部分/表单数据”帖子,而您发送的是常规的“url编码”帖子 相反,您应该查看示例或()文档
你可以更改服务器端。
没有C++,只是C。我尝试将方法改为“CurLopt*Poad”,但也不工作。有一个简单的方法使用我的C代码吗?只实施一些更改?因为示例“multi-post.c”让我很难理解。我已经回答了这个问题。如何修复进行表单后期上传的代码。如果您现在突然想做其他事情,那么请确定您需要一些其他代码,但这不再是这个问题,因此,我很抱歉,但我不会继续在这里作为评论沿着这条路线走下去!
