全部，我在 ASP 中有以下代码：
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
</head>
<body>
<div>
<form id="Form2" Method="Post" EncType="Multipart/Form-Data" RunAt="Server">
<%-- The File upload Html control --%>
Choose Your File To Upload <BR>
<Input Name="MyFile" id="MyFile" Type="File" RunAt="Server">
<BR>
<%-- A button - when clicked the form is submitted and the
Upload_Click event handler is fired... --%>
<Input id="Submit1" Type="Submit" Value="Upload"
RunAt="Server">
</form> </div>
</body>
</html>
以及客户端VB.NET中的以下算法：
- 将内容类型设置为“multipart/form-data;boundary=---------------------------”+时间戳
- 写“\n\r--------------”+时间戳+“\n\r”
- 写入 "Content-Disposition: form-data; name="MyFile"; filename="12345.bmp"\r\nContent-Type: image/bitmap\r\n\r\n"
- 发布“12345.bmp”的内容
我正在尝试使用 libCURL 将其转换为 C++。
这是我所做的：
wxString header = wxString::Format( "Content-Disposition: form-data;
name=\"MyFile\"; filename=\"%s\"", fileName );
post = curl_slist_append( post, "Content-Type: multipart/form-data;
boundary=---------------------------12345" );
post = curl_slist_append( post, header.c_str() );
if( !post )
{
return;
}
post = curl_slist_append( post, "Content-Type: image/bitmap" );
if( !post )
{
curl_slist_free_all( post );
return;
}
result = curl_formadd( &first, &last, CURLFORM_COPYNAME, "name",
CURLFORM_FILE, (const char *) fileName.c_str(), CURLFORM_END );
result = curl_formadd( &first, &last, CURLFORM_COPYNAME, "filename",
CURLFORM_COPYCONTENTS, (const char *) fileName.c_str(),
CURLFORM_CONTENTHEADER, post, CURLFORM_END );
result = curl_formadd(&first, &last, CURLFORM_COPYNAME, "submit",
CURLFORM_COPYCONTENTS, "send", CURLFORM_END );
if( result )
{
curl_slist_free_all( post );
curl_formfree( first );
return;
}
FILE *fp = fopen( "session.log", "w+" );
if( !fp )
{
curl_slist_free_all( post );
curl_formfree( first );
return;
}
curl_easy_setopt( handle, CURLOPT_VERBOSE, 1L );
curl_easy_setopt( handle, CURLOPT_HEADER, 1L );
curl_easy_setopt( handle, CURLOPT_STDERR, fp );
curl_easy_setopt( handle, CURLOPT_ERRORBUFFER, errorMsg );
curl_easy_setopt( handle, CURLOPT_URL, "http://xxx.xxx.xxx.xxx/Default.aspx" );
curl_easy_setopt( handle, CURLOPT_HTTPPOST, first );
error = curl_easy_perform( handle );
if( !error )
{
curl_slist_free_all( post );
curl_formfree( first );
return;
}
curl_slist_free_all( post );
curl_formfree( first );
curl_easy_setopt( handle, CURLOPT_HTTPPOST, NULL );
curl_easy_setopt( handle, CURLOPT_HTTPHEADER, NULL );
但不幸的是，它失败了。人们在 Windows 上使用什么来检查数据包的发送方式？或者也许有人可以在我的代码转换中发现问题？
谢谢你。
