Hi,
How do I manually create nested POST parameters for a http web request? I
have a .NET C# client for which I'm creating a HTTP request to a Rails
page. Everything is fine so far, however I've noted that the parameters I'm
creating for the request (key/value pairs) are expected to be nested. I'm
actually also having a hard time trying to work out in a controller
before_filter how to do a "puts" on the raw request content to see how a
successful request formats it.
*
RAILS BACKEND EXPECTATION* (a successful login file, when I called from
browser (not .net))
action_controller.request.request_parameters:
!map:HashWithIndifferentAccess
commit: Save
*webfile*: !map:HashWithIndifferentAccess
*path*: winter
*file*: &id005 !ruby/object:File
content_type: image/jpeg
original_path: Winter.jpg
*C# Parameter Creation*:
var form = new NameValueCollection();
form["path"] = "winter"; ==> THIS DOESN'T WORK BECAUSE I THINK
IT MAY HAVE TO BE NESTED WITHIN THE "webfile" HASH
*C# Routine*:
public static HttpWebResponse Upload(HttpWebRequest req,
UploadFile[] files, NameValueCollection form)
{
List<MimePart> mimeParts = new List<MimePart>();
try
{
foreach (string key in form.AllKeys)
{
StringMimePart part = new StringMimePart();
part.Headers["Content-Disposition"] = "form-data;
name=\"" + key + "\"";
part.StringData = form[key];
mimeParts.Add(part);
}
int nameIndex = 0;
foreach (UploadFile file in files)
{
StreamMimePart part = new StreamMimePart();
if (string.IsNullOrEmpty(file.FieldName))
file.FieldName = "file" + nameIndex++;
part.Headers["Content-Disposition"] = "form-data;
name=\"" + file.FieldName + "\"; filename=\"" + file.FileName + "\"";
part.Headers["Content-Type"] = file.ContentType;
part.SetStream(file.Data);
mimeParts.Add(part);
}
string boundary = "----------" +
DateTime.Now.Ticks.ToString("x");
req.ContentType = "multipart/form-data; boundary=" +
boundary;
req.Method = "POST";
long contentLength = 0;
byte[] _footer = Encoding.UTF8.GetBytes("--" + boundary +
"--\r\n");
foreach (MimePart part in mimeParts)
{
contentLength +=
part.GenerateHeaderFooterData(boundary);
}
req.ContentLength = contentLength + _footer.Length;
byte[] buffer = new byte[8192];
byte[] afterFile = Encoding.UTF8.GetBytes("\r\n");
int read;
using (Stream s = req.GetRequestStream())
{
foreach (MimePart part in mimeParts)
{
s.Write(part.Header, 0, part.Header.Length);
while ((read = part.Data.Read(buffer, 0,
buffer.Length)) > 0)
s.Write(buffer, 0, read);
part.Data.Dispose();
s.Write(afterFile, 0, afterFile.Length);
}
s.Write(_footer, 0, _footer.Length);
}
return (HttpWebResponse)req.GetResponse();
}
catch
{
foreach (MimePart part in mimeParts)
if (part.Data != null)
part.Data.Dispose();
throw;
}
}
Thanks
