Jquery - Mvc File Upload Ajax Post?
May 6, 2010
I was just wondering if its possible to do an ajax post a file in asp.net mvc,basically i have a form with two buttons, one of the buttons extracts images for the selected document and displays them for the user to choose thumbnails for the document he is about to upload. The usee then fills out the rest of the form and then saves the document.With the image extraction, I was owndering if it was possible to do that as an ajax post. The other submit button can work as a normal http post

function startUpload(sender, args){}
but how to access the content type of the file selected by user.

Here is my code to post the file. I use asp fileupload control to get the file stream.
HttpWebRequest requestToSender = (HttpWebRequest)WebRequest.Create [URL]
requestToSender.Method = "POST";
requestToSender.ContentType = "multipart/form-data";
requestToSender.KeepAlive = true;
requestToSender.Credentials = System.Net.CredentialCache.DefaultCredentials;
requestToSender.ContentLength = BtnUpload.PostedFile.ContentLength;
BinaryReader binaryReader = new BinaryReader(BtnUpload.PostedFile.InputStream);
byte[] binData = binaryReader.ReadBytes(BtnUpload.PostedFile.ContentLength);
Stream requestStream = requestToSender.GetRequestStream();
requestStream.Write(binData, 0, binData.Length);
requestStream.Close();
HttpWebResponse responseFromSender = (HttpWebResponse)requestToSender.GetResponse();
string fromSender = string.Empty;
using (StreamReader responseReader = new StreamReader(responseFromSender.GetResponseStream()))
{
fromSender = responseReader.ReadToEnd();
}
XMLString.Text = fromSender;
In the page load of CrossPage.aspx i have the following code
NameValueCollection postPageCollection = Request.Form;
foreach (string name in postPageCollection.AllKeys)
{
Response.Write(name + " " + postPageCollection[name]);
}
HttpFileCollection postCollection = Request.Files;
foreach (string name in postCollection.AllKeys)
{
HttpPostedFile aFile = postCollection[name];
aFile.SaveAs(Server.MapPath(".") + "/" + Path.GetFileName(aFile.FileName));
}
string strxml = "sample";
Response.Clear();
Response.Write(strxml);
I don't get the file in Request.Files. The byte array is created. What was wrong with my HttpWebRequest?

I'm trying to upload a file to an ASP 2.0 web service through HTTP 1.1 POST from a client-side application. If my web service function is declared as
<WebMethod()>
Public Function UploadFile(ByVal file as Byte(), ByVal fileName as String) as String
...
The test form says the request should take this form:
POST address_of_service HTTP/1.1
Host: <host>
Content-Type: application/x-www-form-urlencoded
Content-Length: length
file=string&file=string&fileName=string
How do I get my binary file data into that form? I've tried just converting the file data to a string and putting it in the body (file=<string_data_here>) but I get HTTP 500 errors back, complaining about not being able to convert it to System.Byte. I've got HTTP POST working fine elsewhere in my application with plain string parameters. Also, out of curiosity, why is it showing the file parameter twice?

I haven't used Jquery to post Json data to mvc before, so this maybe a Noob issue.
I've got a really simple form, and am trying to post this data async to an mvc action. Within firefox I can see the data being posted, but I can't see it within the MVC action.
This code all runs through correctly, but putting a debug point in the action method will always show the form collection as empty.
Form..

I need to pass a customer id to get some data back for a customer from a webservice. I can't figure out how to get to the webservice, I have a breakpoint set in the webmethod but it's not being hit and the alert box is not popping up either. For a test I am just trying to show some value from the returned data in an alert box. Note I am just hard coding the customer id of 1001. The webmethod takes a parameter of string customerid.

Does some one know what's missing or how to debug this issue?

I have a WCF web service and jQuery AJAX implementation that appears to be working perfectly, save for a single line of code: the AJAX calls to the WCF service only have the correct HTTP header & content information if I use GET in my AJAX calls. Once I choose to use POST, the WCF service response with "Method Not Allowed". The calls are coming from domains such as sub1.domain.com, and calling svc.domain.com. How can I configure WCF to allow the cross domain AJAX POSTs?
