Need a C# Web Service to call external Web Services. How?

I need to create a back-end web service which then calls a small handful of external web services in order to complete the calculations. Is this a simple task? Using C# to execute an external web service?

How would I call four different such calls at the same time? Does this qualify as "parallel processing"? Anything fancy needed? Or, can I quickly call one after the other, then get a callback for each?

How does this work?

Thanks

Hi
I think I am ready to roll on my final proper game coding.

I can get html/javascript code running from my local OS X XAMPP 7.2 local server, of course, w MacBook IP address..but is isn't always-up, and I need it always on.

But, for an intended final product, I've been looking at the options for a real-world type dev system.

It looks like Amazon Web Services has very reasonable options for eventual monthly billing. here

I'll use the free tier.
For now, I need only the ability to put a simple page up that can load a device .io game in html and serve the game code to the player browser / device correctly.
Is that what gameLift is suited for? If I put my working .io game directory in my Godaddy space, it doesn't work. I apologize for bringing up Godaddy again. It'll be the last time, I hope. So, gamelift can serve an .htm that pulls up its .io code?
Is gamelift mainly for MMO games / games w player accounts?
I'd say that - My first game - .io game - is most similar to games like word-scapes and Drag-'n-Merge, not yet fortnite or Slither.io

Thanks

I have an Ubuntu server running 10.04.6 LTS. It is providing web services. I have setup sftp and given permission to an 'sftp' group to login but have set their root directory to be /var/www/html. They are able to connect to the server but cannot write to the folder. I use setfacl to give the group write permission. If they are already logged in, they can now create folders and files. However, once they logout, they can no longer login. If I remove the acl, the condition reverses again. It is not limited to acls though. I even tried just giving 'other' write-access. Same thing happened.

Experts,
Seeking your inputs please. The situation is as follows:

1) I have a HTTP listener running on a port (say 8083) on a Windows 2012 Server.
2) A client application continuously sends SOAP request to and receive a SOAP response from my listener.
3) There are instances when two successive requests are sent within a span of 10ms
4) The second request on the client application always results in the error 'Connection Refused' in the client logs. The owner of the client application believes my listener refused to accept the connection.
5) I am kind of confident it did not reach the listener, but not entirely sure if the connection was refused by the OS on the server.

Can I please know if there is a way to check if such a request was ever received at the listener port? Any kind of Windows logs or internal tools that can help me here?

Thanks.

Hello Experts,
I have built few HTTP 1.1 listen service mocks using SoapUI and CA DevTest tools. Every request to the service from a client like Postman is established as a new connection. Inserting a custom header Connection:Keep-Alive into the request and also the response is not making any difference. Can I know is there more to be done to have the socket open for successive connections happening within a second?

Thanks.

Monetizing an API

Hi all,

We have been asked by a client to open private access to our API. This will be monetized, and they would like us to provide a pricing model.

I have no idea where to start, i know the types of ways we can charge them (per user, usage, requests, etc), but i have no idea which is best for our use case, and how do we even go about building a mechanism to monitor usage for billing.

Our API is REST based (currently for internal use of a webapp and mobile app) and sends data to the cloud to be run against ML models which then spit back confidence scores to the applications.

My next question is regarding architecture, would we implement a layer between our ML Service and our clients that would implement oauth2/monitoring of API usage?

Hi
I think I mucked up a decision a few weeks back.
A sparkly girl from Godad called me one morning during a remorseless coding buzz of mine.
She said they had reviewed my godaddy account and were uncertain about my server decisions.
Apparently, they had a new package deal for a "non-VPS" server of my own to handle my games' (plural) needs.
I didn't sense any red flags, so listened on.
I told her I needed a server to handle my games' traffic and deliver appropriate responses and content to the user.
She didn't object. and told me it would be my own dedicated machine. - And could do what I needed.
I was admittedly skeptical, bec if this was a special deal for a personal server, they'd need quite a big farm for all the potential global individual clients?
I should have asked her where the location was and how many clients had servers.
Anyway, she said it was a short time offer, and I thought it was a good deal for my needs and I bought the damn thing at $1,000
Can I salvage this blunder? Was it a blunder?
Can I work with the thing the sold me to make phone games?
I have since discovered Amazon web services which would be far better suited to my needs.- only pay for traffic you use.

Does Godaddy have a similar system to AWS? Is it in development?
I can demand a refund for the blunder, and use that money for Godaddy Web Services? Godaddy refunds have to stay within the account.

Thanks

How do I handle this scenario:

A web service will receive data and write to a file on a network share.
Another application is running as a service that checks for files, reads the data, processes, saves the data to a database then deletes the file.
This application must run in multiple data centers and on multiple servers in each data center. How do I ensure that each file is processed
only once.

Hello all! Am having an issue with a web service that I'm trying to debug but it will not "play" within Visual Studio and I can not connect to it on the server with WCF Test client or a test application though adding the service to the test application does work and only breaks when building the application.

HI, I am writing a soap web service.
The response that I got is starting with : <soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">,
but it require to be : <env:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">.

I tried to add below line code in package-info.java, to replace the soap prefix with env, but it didn't work.
xmlns = {

WCF service granularity

I am developing an electronic medical record (EMR) system.

I am designing and implementing the backend APIs using WCF.

Now, I have two system actors: secretary and doctor.

I designed the services according to the actor he/she is concerned.

[ServiceContract]
public interface ISecretaryService
{
}

[ServiceContract]
public interface IDoctorService : ISecretaryService
{
//the doctor has the functions of secretary in case she was absent!

The problem is I have duplicate code which is the implementation of the ISecretary contract in doctor service.

Need a cost effective alternative to SiteGround Grow Big account.

Most of the time they seem like a good solution, but then something happens usually around DNS updates and they just fall apart. My latest headache with them involves moving an SNPP (Port 444) connection into AWS with the host name in Route 53 and the connection in the Dynamic Load Balancer. Well that apps, been done all day. They don't allow you to DIG, PING or NSLOOKUP from the SSH CLI, and they always seem to feel that they should own the DNS registration.

This is the third time this year already I have had similar issues and I need to look again. Might move to AWS, but the nature of the sites seem to imply a variance in cost month to month and possibility of a HUGE surprise one month.

Mostly a mix of PHP, Static HTML and WORDPRESS (Gravity and Genesis Enterprise) ..

I am out Tuesday, so will apologize in advance for any slow responses.

Hey

I am new here and in my spare time (as a hobby) I try to make utilities for use at my school (I work at a school administration). For this I use Delphi XE7. But now I have a problem that I can't find a solution for. Hopefully you can help me with that.

I have recently been forced to communicate via a web service. For this I have to use the "sendmsg" function. In the imported supplied WSDL file, the function is defined as follows:

function sendMsg(const accesscode: string; const userIdentifier: string; const title: string; const body: string; const senderIdentifier: string; const attachments: Variant; const coaccount: Integer; const copyToLVS: Boolean): Variant; stdcall;

The server with which I have to communicate describes the function as follows:

sendMsg

With this method you can send a message to the main account or a co-account of a specific user. Specifying the sender and / or attachment is optional.
•      string $accesscode: Web services password
•      string $userIdentifier: Unique field user of the recipient
•      string $title: Title of the message
•      string $body: Text of the message
•      string $senderIdentifier: Unique field user of the sender (optional)
•      mixed $attachments: Attachments (1 or more) in base64 encoding (optional)
•      integer $coaccount: Type of account ('0' = main account, '1' = co-account 1 or '2' = co-account 2…). $ coaccount is optional: if this is not specified then the message will be sent to the…

REST and WCF SOAP Frameworks.

Hi,

I have a question. I have a existing WCF type framework that has like 8 difference .svc's and in each one of those .svc's there are like 40 different web services (methods) that are called. This is in ASP.NET and C#.

I am going to start implementing REST aspects as well with ASP.NET and C#.

Is it wise to maintain 2 separate frameworks? One for REST methods (could also be 10-20 different methods) and that over existing SOAP svc's? Or do I combine the REST calls/process into the existing WCF?

If the suggestion is 2 separate frameworks... does anybody have an example of how that would be done in REST?

Any information would be greatly appreciated.

Thanks!

The wizard is asking about an Application Directory Partition, do I create one to support web services for Great Plains? If so, the example shows CN=Partition1 ,DC=Woodgrove, DC=COM.

Does this mean that:

DC would be LOCAL instead of COM if the AD is domainname.local?
