Hello,
I and using nginx 1.0.15 with the third-party module
nginx_upload_module-2.2.0/
When I am using an html form all works perfectly and I can see the
uploaded files and the post values as expected.
But, when I send the HTTP Post request from a Poco application, it does
not work. (pocoproject.org)
I am pasting below the code of that C++ Poco app. I don't think that you
need to be an expert at Poco to understand it.
114 std::ostringstream content;
115 content << "------WebKitFormBoundaryq2BIJhJChD7qIY1W\r\n";
116 content << "Content-Disposition: form-data;
name=\"submit\"\r\n\r\n"
117 "Upload\r\n"
118 "------WebKitFormBoundaryq2BIJhJChD7qIY1W\r\n";
119 content << "Content-Disposition: form-data; name=\"file\";
filename=\"test.txt\"\r\n\r\n"
120 "Content-Type: text/plain\r\n"
121 "This is a test.\r\n"
122 "------WebKitFormBoundaryq2BIJhJChD7qIY1W--";
123
124 std::ostringstream os;
125 os << "POST /upload HTTP/1.0\r\n"
126 "Host: ip:31000\r\n"
127 "User-Agent: AAA\r\n"
128 "Accept:
text/plain,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8\r\n"
129 "Accept-Language:
en-us,ko;q=0.9,ja;q=0.7,cs;q=0.6,th;q=0.4,zh;q=0.3,en;q=0.1\r\n"
130 "Accept-Encoding: gzip,deflate\r\n"
131 "Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7\r\n"
132 "Referer: ip\r\n"
133 "Content-Type: multipart/form-data;
boundary=------WebKitFormBoundaryq2BIJhJChD7qIY1W\r\n";
134
135 os << "Content-Length: " << strlen(content.str().c_str()) <<
"\r\n\r\n";
136 os << content.str();
137
138 Poco::Net::SocketAddress sa("ip", 31000);
139 Poco::Net::StreamSocket socket(sa);
140 Poco::Net::SocketStream str(socket);
141 str << os.str();
142 str.flush();
143 Poco::StreamCopier::copyStream(str, std::cout);
144 return;
I am getting this from the server
HTTP/1.1 200 OK
Server: nginx/1.0.15
Date: Mon, 23 Apr 2012 02:00:45 GMT
Content-Type: text/html
Connection: close

Content-Length: 98

Drilling into
nginx_upload_module-2.2.0/ngx_http_upload_module.c
It seems that the problem is inside the function
static ngx_int_t upload_process_buf(ngx_http_upload_ctx_t *upload_ctx,
u_char *start, u_char *end)
and more precisely, it appears that from the html from the scope below
is entered while from the poco app it is never entered
3509 if(upload_ctx->boundary_pos == upload_ctx->boundary.data +
upload_ctx->boundary.len)
3510 {
3512 upload_ctx->state = upload_state_after_boundary;
3513 upload_ctx->boundary_start = upload_ctx->boundary.data;
3514 upload_ctx->boundary_pos = upload_ctx->boundary_start;
3515 }
maybe my header is wrong... I am running out of ideas to make this work
I am pasting below the config file:

Note that if I disable the module
'--add-module=/root/nginx/agentzh-chunkin-nginx-module-ddc0dd5", the
issue remains
Thanks in advance for any idea
