jQuery Ajax POSTing array to ASP.NET MVC Controller

I'm missing something here. I've got this jQuery JavaScript:

$.ajax({
    type: "POST",
    url: "/update-note-order",
    dataType: "json",
    data: {
        orderedIds: orderedIds,
        unixTimeMs: new Date().getTime()
    }
});

Where orderedIds is a JavaScript number array (e.g. var orderedIds = [1, 2]).

The handling Controller method is:

[HttpPost]
public void UpdateNoteOrder(long[] orderedIds, long unixTimeMs)
{
    ...
}

When I put a Debugger.Break() in UpdateNoteOrder(), orderedIds is null in the Watch window. (unixTimeMs, however, has a numeric value.)

How do I pass the number array through $.ajax() such that orderedIds is a long[] in my controller?

Access POST values in Symfony2 request object

OK, this is a newbie question, but I can't find the answer anywhere. In a controller in Symfony2, I want to access the POST value from one of my forms. In the controller I have:

public function indexAction()
{ 
    $request = $this->get('request');
    if ($request->getMethod() == 'POST') {
        $form = $this->get('form.factory')->create(new ContactType());
        $form->bindRequest($request);
        if ($form->isValid()) {
            $name_value = $request->request->get('name');

Unfortunately $name_value isn't returning anything. What am I doing wrong? Thanks!

Should I URL-encode POST data?

I'm POSTing data to an external API (using PHP, if it's relevant).

Should I URL-encode the POST variables that I pass?

Or do I only need to URL-encode GET data?

Thanks!

UPDATE: This is my PHP, in case it is relevant:

$fields = array(
    'mediaupload'=>$file_field,
    'username'=>urlencode($_POST["username"]),
    'password'=>urlencode($_POST["password"]),
    'latitude'=>urlencode($_POST["latitude"]),
    'longitude'=>urlencode($_POST["longitude"]),
    'datetime'=>urlencode($_POST["datetime"]),
    'category'=>urlencode($_POST["category"]),
    'metacategory'=>urlencode($_POST["metacategory"]),
    'caption'=>($_POST["description"])
);
$fields_string = http_build_query($fields);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch,CURLOPT_POST,count($fields));
curl_setopt($ch,CURLOPT_POSTFIELDS,$fields);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$response = curl_exec($ch);

Is there a max size for POST parameter content?

I'm troubleshooting a java app where XML is sent between two systems using HTTP POST and a servlet. I suspect that the problem is that the XML is growing way too big. Is it possible that this is the problem? Is there a limit?

When it doesn't work, the request.getParameter("message") on the consumer side will return null.

Both apps are running on tomcat

For instance, an XML document of size 1.73mb will not make it through..

Sending an HTTP POST request on iOS

I've been stuck on this problem for weeks now so I would really appreciate some help. Im trying to send an http Post with the ios application that im developing but the push never reaches the server although I do get a code 200 as response (from the urlconnection). I never get a response from the server nor does the server detect my posts (the server does detect posts coming from android)

I do use ARC but have set pd and urlConnection as strong.

This is my code for sending the request

 NSMutableURLRequest *request = [[NSMutableURLRequest alloc]
                                    initWithURL:[NSURL URLWithString:[NSString stringWithFormat:@"%@%@",dk.baseURL,@"daantest"]]];
    [request setHTTPMethod:@"POST"];
    [request setValue:@"text/xml"
   forHTTPHeaderField:@"Content-type"];

    NSString *sendString = @"<data><item>Item 1</item><item>Item 2</item></data>";

    [request setValue:[NSString stringWithFormat:@"%d", [sendString length]] forHTTPHeaderField:@"Content-length"];

    [request setHTTPBody:[sendString dataUsingEncoding:NSUTF8StringEncoding]];
    PushDelegate *pushd = [[PushDelegate alloc] init];
    pd = pushd;
    urlConnection = [[NSURLConnection alloc] initWithRequest:request delegate:pd];
    [urlConnection start];

this is my code for the delegate

#import "PushDelegate.h"

@implementation PushDelegate
@synthesize data;

-(id) init
{
    if(self = [super init])
    {
        data = [[NSMutableData alloc]init];
        [data setLength:0];
    }
    return self;
}

{
    NSLog(@"didwriteData push");

    NSLog(@"did send body");
}

{
    [self.data setLength:0];
    NSHTTPURLResponse *resp= (NSHTTPURLResponse *) response;
    NSLog(@"got responce with status @push %d",[resp statusCode]);
}

- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)d
{
    [self.data appendData:d];

    NSLog(@"recieved data @push %@", data);
}

- (void)connectionDidFinishLoading:(NSURLConnection *)connection
{
    NSString *responseText = [[NSString alloc] initWithData:self.data encoding:NSUTF8StringEncoding];

    NSLog(@"didfinishLoading%@",responseText);

}

- (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error
{
    [[[UIAlertView alloc] initWithTitle:NSLocalizedString(@"Error ", @"")
                                message:[error localizedDescription]
                               delegate:nil
                      cancelButtonTitle:NSLocalizedString(@"OK", @"")
                      otherButtonTitles:nil] show];
    NSLog(@"failed &push");
}

// Handle basic authentication challenge if needed
- (void)connection:(NSURLConnection *)connection didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge
{
    NSLog(@"credentials requested");
    NSString *username = @"username";
    NSString *password = @"password";

    NSURLCredential *credential = [NSURLCredential credentialWithUser:username
                                                             password:password
                                                          persistence:NSURLCredentialPersistenceForSession];
    [[challenge sender] useCredential:credential forAuthenticationChallenge:challenge];
}

@end

The console always prints the following lines and the following lines only:

Send POST Request with Data Specified in File via Curl

I need to make a POST request via Curl from the command line. Data for this request is located in a file. I know that via PUT this could be done with the --upload-file option.

curl host:port/post-file -H "Content-Type: text/xml" --data "contents_of_file"

Simple MVC3 Question - How to retreive form values from HTTPPOST, dictionary or?

Simple question. I have an mvc controller that has method:

[HttpPost]
public ActionResult SubmitAction()
{
     // Get Post Params Here
 ... return something ...
}

The form is a non-trivial form with a simple textbox.

Question - how on earth do I access the parameter values? I am not posting from a View, the post is coming externally. I'm assuming there is a collection of key/value pairs I have access to. I tried Request.Params.Get("simpleTextBox"); but it returns error "Sorry, an error occurred while processing your request.".

I'm sure there's a simple answer to this.

How to POST raw whole JSON in the body of a Retrofit request?

This question may have been asked before but no it was not definitively answered. How exactly does one post raw whole JSON inside the body of a Retrofit request?

See similar question here. Or is this answer correct that it must be form url encoded and passed as a field? I really hope not, as the services I am connecting to are just expecting raw JSON in the body of the post. They are not set up to look for a particular field for the JSON data.

I just want to clarify this with the restperts once and for all. One person answered not to use Retrofit. The other was not certain of the syntax. Another thinks yes it can be done but only if its form url-encoded and placed in a field (that's not acceptable in my case). No, I can't re-code all the services for my Android client. And yes, it's very common in major projects to post raw JSON instead of passing over JSON content as field property values. Let's get it right and move on. Can someone point to the documentation or example that shows how this is done? Or provide a valid reason why it can/should not be done.

UPDATE: One thing I can say with 100% certainty. You CAN do this in Google's Volley. It's built right in. Can we do this in Retrofit?

ios Upload Image and Text using HTTP POST

Thanks for reading.

I am new to iOS and I am trying to upload an Image and a text using multi-part form encoding in iOS.

The curl equivalent is something like this: curl -F "param1=value1" -F "param2=@testimage.jpg" "http://some.ip.address:5000/upload"

The curl command above returns the expected correct response in JSON.

Problem: I keep getting a HTTP 400 request which means I am doing something wrong while composing the HTTP POST Body.

What I Did: For some reference, I tried Flickr API iOS app "POST size too large!" and Objective C: How to upload image and text using HTTP POST?. But, I keep getting a HTTP 400.

I tried the ASIHttpRequest but had a different problem there (the callback never got called). But, I didn't investigate further on that since I've heard the developer has stopped supporting the library: http://allseeing-i.com/[request_release];

Could someone please help me out?

How to add parameters to HttpURLConnection using POST

I am trying to do POST with HttpURLConnection(I need to use it this way, can't use HttpPost) and I'd like to add parameters to that connection such as

post.setEntity(new UrlEncodedFormEntity(nvp));

where

nvp = new ArrayList<NameValuePair>();

having some data stored in. I can't find a way how to add this ArrayList to my HttpURLConnection which is here:

HttpsURLConnection https = (HttpsURLConnection) url.openConnection();
https.setHostnameVerifier(DO_NOT_VERIFY);
http = https;
http.setRequestMethod("POST");
http.setDoInput(true);
http.setDoOutput(true);

The reason for that awkward https and http combination is the need for not verifying the certificate. That is not a problem, though, it posts the server well. But I need it to post with arguments.

Any ideas?

How to post data in PHP using file_get_contents?

I'm using PHP's function file_get_contents() to fetch contents of a URL and then I process headers through the variable $http_response_header.

Now the problem is that some of the URLs need some data to be posted to the URL (for example, login pages).

How do I do that?

I realize using stream_context I may be able to do that but I am not entirely clear.

Thanks.

When do you use POST and when do you use GET?

From what I can gather, there are three categories:

1. Never use GET and use POST
2. Never use POST and use GET
3. It doesn't matter which one you use.

Am I correct in assuming those three cases? If so, what are some examples from each case?

How do you extract POST data in Node.js?

How do you extract form data (form[method="post"]) and file uploads sent from the HTTP POST method in Node.js?

I've read the documentation, googled and found nothing.

function (request, response) {
    //request.post????
}

Is there a library or a hack?

How do I manually fire HTTP POST requests with Firefox or Chrome? [closed]

I want to test some URLs on a web application I'm working on. For that I would like to manually create HTTP POST requests (meaning I can add whatever parameters I like).

Is there any extension or functionality in Chrome and/or Firefox that I'm missing?
