I'm new to creating apps and intgrations as a whole and learning this as I go. I've been attempting to get this to work within our Demo account for a few days. The issue I'm running into now using the QuickStart for Powershell when the code below runs and I Allow, it doesn't pass back to Powershell with the access token file created. Powershell just hangs with the flashing cursor until I force quit. This is keeping me from being able to make the calls in Demo before pushing the app over into our Prod account. Any advice you can provide is appreciated.

Ok. You may close this tab and return to the shell. This window closes automatically
in five seconds.
<script type="text/javascript">

I want to do this things :
select a session
make a dump of this session (the issue is here)
Plus, I want to do that without modification of Fiddler Rules. I have done this with a modification of Fiddler Rules but the program will be used on several machines and it can be difficult to change Fiddler Rules in every machines.
I don't know if it is possible.
The code to do that with the modification of the fiddler Rules is :
PowerShell :
$filePath = "...\nameFile.txt" # file which contain the names of fiddler ZIP files
$file = Get-Content $filePath # content of nameFile
foreach ($line in $file) {
start $line # open the file
Write-Host "File : $line open"
Start-Sleep -s 1
}
& "...\Fiddler\ExecAction.exe" "failuresselection" # select all failures and make another file (see Fiddler Rules)
Fiddler Rules :
static function OnExecAction(sParams: String[]): Boolean {
[...]
// Select all failures and put them in a new ZIP file
case "failuresselection":
var path = "...\\Newlogs";
UI.actSelectSessionsWithResponseCode(449);
if (UI.GetFirstSelectedSession() != null){
UI.actSaveSessionsToZip(path+"\\Logs" + 449 + ".saz");
}
// Confirmation
FiddlerObject.StatusText = "Dumped all failures sessions to " + path;
UI.actExit();
return true;
[...]
}
I try this but it doesn't worked :
& "...\Fiddler\ExecAction.exe" "FiddlerApplication.UI.actSelectAll();"
It's to select all line but I think that ExecAction.exe replace QuickExec.
In summary, I am searching a way to do the same thing without modification of Fiddler Rules.
I'm using a standard [System.Net.WebRequest] class to return the HTTP response code of a given URL.
The URL points to an internal web application server, which returns a "401 Unauthorised" error. This is actually OK as the service account running the script doesn't have a valid account to the application. However, I am more interested that the website is responding. However, I assumed that this is a HTTP Response in itself so I could manage this, but instead it returned as a null value.
$HTTP_Request = [System.Net.WebRequest]::Create('http://google.com')
$HTTP_Response = $HTTP_Request.GetResponse()
$HTTP_Status = [int]$HTTP_Response.StatusCode
Exception calling "GetResponse" with "0" argument(s): "The remote
server returned an error: (407) Proxy Authentication Required."
(I'm using Google in this example, which our servers are blocked from accessing external sites).
So I can't get as far as $HTTP_Status = [int]$HTTP_Response.StatusCode in the code because it won't accept 400 errors as a code.
How can I accept a 401 (or 407 in this example) in the query?
Thanks
Got it!
try{
$request = $null
$request = Invoke-WebRequest -Uri "<URL>"
}
catch
{
$request = $_.Exception.Response
}
$StatusCode = [int] $request.StatusCode;
$StatusDescription = $request.StatusDescription;
You could've done:
$HTTP_Request = [System.Net.WebRequest]::Create('http://google.com')
$HTTP_Request.Method = "GET"
$HTTP_Request.Credentials = [System.Net.CredentialCache]::DefaultNetworkCredentials
[System.Net.HttpWebResponse]$HTTP_Response = $HTTP_Request.GetResponse()
Try {
$HTTP_Status = [int]$HTTP_Response.StatusCode
}
Catch {
#handle the error if you like, or not...
}
If ($HTTP_Status -eq 200) {
Write-Host "Good Response"
} Else {
Write-Host "Site Down or Access Denied"
}
# If you got a 404 Not Found, the response will be null so can't be closed
If ($HTTP_Response -eq $null) { } Else { $HTTP_Response.Close() }
You were missing the authentication piece:
$HTTP_Request.Credentials = [System.Net.CredentialCache]::DefaultNetworkCredentials
I re-read your post and because your service account did not have access to the URL you are hitting (which was not actually google.com... you should've put myserver.com...grr), you would never actually get a 200, but always will get an exception. This is a bad practice, because instead of looking for the 200, you would have to always look for the 401 or 407 Unauthorized exception status code specifically, and if the code/response changed to something else, only then is it considered a failure - but technically it always had been a failure, because it never reached the site! It masks potential issues if you intend to go on deliberately using a site your service account doesn't have access to reach. And if your service account was ever granted access, your code would have to be updated.
I have need of retrieving and inspecting the delegate forwarding rule (the built-in delegate commands in EWS being inadequate for my needs since they choke on groups being used as delegates).
I am able to successfully locate the rule created by "Schedule+ EMS Interface". However, I am unable to retrieve PR_RULE_ACTIONS. Turning on tracing.
I see that the PidTagRuleMsgProvider property is getting returned just fine, but PR_RULE_ACTIONS never does.
I suspect that I am using the wrong MAPI property type in the propertyset definition, but I've gone through everything listed at http://msdn.microsoft.com/en-us/library/exchangewebservices.mapipropertytypetype(v=exchg.140).aspx . Any clues?
Here is the relevant snippet of code:

Glen Scales was able to set me on the right path. It turns out that PR_RULE_ACTIONS is not exposed via EWS, but the same data exposed via an attribute called PR_EXTENDED_RULE_ACTIONS. Now I'm happily slinging code to parse the binary blob.
http://msdn.microsoft.com/en-us/library/ee218391(v=EXCHG.80).aspx
The property tag for PR_RULE_ACTIONS is 0x668000FE. You can see it (and the property data) in OutlookSpy (I am its author) - go to the Inbox folder, click IMAPIFolder button, go to the PR_RULES_TABLE tab, select the rule, double click on the PR_RULE_ACTIONS property.
Note that PT_ACTIONS MAPI type (0x000FE) is only accessing in Extended MAPI, I don't think EWS will be able to return it.
I have my little 3-sided socket-server. Each server has its own hash with its key-values.
The very first is:
$Local = #{ID="Local"; ...}
$RemtA = #{ID="RemtA"; ...}
$RemtB = #{ID="RemtB"; ...}
I start for all of the the listeners - no problem.
If now a client wants to connect, I want to add the ID to $ProgressHead, which is defined like this:
$ProgressHead = "Value-Broadcast, Connected: "
and used in my function to accept a client called with its hash as $h:
if ( !$h.Connected ) {
#Write-Host "$($h.ID) not connected, pending: $($h.listener.Pending())"
if ( $h.listener.Pending()) {
$h.client = $h.listener.AcceptTcpClient() # will block here until connection
$h.stream = $h.client.GetStream();
$h.writer = New-Object System.IO.StreamWriter $h.stream
$h.writer.AutoFlush = $true
$h.Connected = $true
Write-Host $Global:ProgressHead # fails - empty ??
Write-Host $h.ID # prints oh depit it is marked as error
if ( !$Global:ProgressHead.Contains( $h.ID ) ) { # <= HERE IS THE ERROR ????
$Global:ProgressHead= "$($Global:ProgressHead)$($h.ID) "
}
}
}
The Error message says:
Can't call a method for an expression which is NULL and $h.ID is underlined
BUT I DO NOT get any error if I start this either in the cmd-console when running powershell -file ThreeServer.ps1 or within the ISE in debug mode. The ID is written correctly to $ProgressHead!
Only if I start this in the Powershell console (PS C:\...> ./ThreeServer.ps1) I get this error, but all the other keys in the lines above are valid ONLY $h.ID on ONLY the PS-console throws this error?
Below is partial code to an experimental http server app I'm building from scratch from a PHP CLI script (Why? Because I have too much time on my hands). The example below more closely matches PHP's manual page on this function. The problem I'm getting is when connecting to this server app via a browser (Firefox or IE8 from two separate systems tested so far), the browser sends an empty request payload to the server and aborts roughly every 1 in 6 page loads.
The server console displays the "Connected with [client info]" each time. However, about 1 in 6 connections will result in a "Client request is empty" error. No error is given telling the header/body response write to the socket failed. The browser will generally continue to read what I give it, but this isn't usable as I can't fulfill the client's intended request without knowing what it is.
<?php
$s_socket_uri = 'tcp://localhost:80';
// establish the server on the above socket
$s_socket = stream_socket_server($s_socket_uri, $errno, $errstr, 30) OR
trigger_error("Failed to create socket: $s_socket_uri, Err($errno) $errstr", E_USER_ERROR);
$s_name = stream_socket_get_name($s_socket, false) OR
trigger_error("Server established, yet has no name. Fail!", E_USER_ERROR);
if (!$s_socket || !$s_name) {return false;}
/*
Wait for connections, handle one client request at a time
Though to not clog up the tubes, maybe a process fork is
needed to handle each connection?
*/
while($conn = stream_socket_accept($s_socket, 60, $peer)) {
stream_set_blocking($conn, 0);
// Get the client's request headers, and all POSTed values if any
echo "Connected with $peer. Request info...\n";
$client_request = stream_get_contents($conn);
if (!$client_request) {
trigger_error("Client request is empty!");
}
echo $client_request."\n\n"; // just for debugging
/*
<Insert request handling and logging code here>
*/
// Build headers to send to client
$send_headers = "HTTP/1.0 200 OK\n"
."Server: mine\n"
."Content-Type: text/html\n"
."\n";
// Build the page for client view
$send_body = "<h1>hello world</h1>";
// Make sure the communication is still active
if ((int) fwrite($conn, $send_headers . $send_body) < 1) {
trigger_error("Write to socket failed!");
}
// Response headers and body sent, time to end this connection
stream_socket_shutdown($conn, STREAM_SHUT_WR);
}
?>
Any solution to bring down the number of unintended aborts down to 0, or any method to get more stable communication going? Is this solvable on my server's end, or just typical browser behavior?
I tested your code and it seems I got better results reading the socket with fread(). You also forgot the main loop(while(1), while(true) or for(;;).
Modifications to your code:
stream_socket_accept with #stream_socket_accept [sometimes you get warnings because "the connected party did not properly respond", which is, of course, the timeout of stream_socket_accept()]
Added the big while(1) { } loop
Changed the reading from the socket from $client_request = stream_get_contents($conn);
to while( !preg_match('/\r?\n\r?\n/', $client_request) ) { $client_request .= fread($conn, 1024); }
Check the source code below (I used 8080 port because I already had an Apache listening on 80):
<?php
$s_socket_uri = 'tcp://localhost:8080';
$s_socket = stream_socket_server($s_socket_uri, $errno, $errstr, 30) OR
trigger_error("Failed to create socket: $s_socket_uri, Err($errno) $errstr", E_USER_ERROR);
$s_name = stream_socket_get_name($s_socket, false) OR
trigger_error("Server established, yet has no name. Fail!", E_USER_ERROR);
if (!$s_socket || !$s_name) {return false;}
while(1)
{
while($conn = #stream_socket_accept($s_socket, 60, $peer))
{
stream_set_blocking($conn, 0);
echo "Connected with $peer. Request info...\n";
// $client_request = stream_get_contents($conn);
$client_request = "";
// Read until double \r
while( !preg_match('/\r?\n\r?\n/', $client_request) )
{
$client_request .= fread($conn, 1024);
}
if (!$client_request)
{
trigger_error("Client request is empty!");
}
echo $client_request."\n\n";
$headers = "HTTP/1.0 200 OK\n"
."Server: mine\n"
."Content-Type: text/html\n"
."\n";
$body = "<h1>hello world</h1><br><br>".$client_request;
if ((int) fwrite($conn, $headers . $body) < 1) {
trigger_error("Write to socket failed!");
}
stream_socket_shutdown($conn, STREAM_SHUT_WR);
}
}
Add sleep(1) after stream_set_blocking
