I'm writing a precompiled Azure function that will perform a SOAP call to ServiceNow. The code works as a standalone exe but I can't seem to get it converted to a precompiled function. In know it's because my DLL can't find the app.config file but what's the best way to get around it. Error message below. ServiceNow requires I set certain bindings and endpoint configuration. The other contractors for their ServiceNowSoapClient class allow me to specify a url directly but don't seem to allow me to get to the binding settings.
Exception while executing function: Functions.TimerTriggerCSharp.
System.ServiceModel: Could not find endpoint element with name
'ServiceNowSoapDev' and contract 'ServiceNowReference.ServiceNowSoap'
in the ServiceModel client configuration section. This might be
because no configuration file was found for your application, or
because no endpoint element matching this name could be found in the
client element.
In WCF you can define your client binding and endpoint programmatically instead of using app.config. Use the constructor of the generated client with two parameters:
new ServiceNowSoapClient(binding, remoteAddress);

I want to get all destinations on subaccount and instance level. In SAP API business Hub, I found the API information and "SAP Cloud SDK" tab to generate code by OpenAPI generator.
https://api.sap.com/api/SAP_CP_CF_Connectivity_Destination/overview
I downloaded the API specification and added dependencies into Cloud SDK for Java project. The code is generated successfully with some errors (unknown models）in generated api classes.
For example in DestinationsOnSubaccountLevelApi.class, model OneOfDestinationNameOnly is imported and used in method but it is not generated in model package.
I looked into API specification and found that there were two types of response entity. That is the reason why the code could not be generated properly. I can modify the API specification to make it work but it should not be the long term solution. Is there any other way to fix this issue?
Unfortunately the SAP Cloud SDK Generator for Open API services is not yet able to understand oneOf relationship that is modeled in the specification.
As an alternative, would you consider using the DestinationAccessor API for resolving single destinations?
You can also directly instantiate an ScpCfDestinationLoader, which allows for querying all destinations:
ScpCfDestinationLoader loader = new ScpCfDestinationLoader();
DestinationOptions options = DestinationOptions
.builder()
.augmentBuilder(ScpCfDestinationOptionsAugmenter.augmenter().retrievalStrategy(ScpCfDestinationRetrievalStrategy.ALWAYS_SUBSCRIBER))
.build();
Try<Iterable<ScpCfDestination>> destinations = loader.tryGetAllDestinations(options);
Similar to the default behavior of DestinationAccessor API, in the code above only the subscriber account will be considered. Other options are:
ScpCfDestinationRetrievalStrategy.ALWAYS_SUBSCRIBER
ScpCfDestinationRetrievalStrategy.ALWAYS_PROVIDER
ScpCfDestinationRetrievalStrategy.SUBSCRIBER_THEN_PROVIDER
I am new to node and typescript. I am working on developing a node library that reaches out to another rest API to get and post data. This library is consumed by a/any UI application to send and receive data from the API service. Now my question is, how do I maintain environment specific configuration within the library? Like for ex:
Consumer calls GET /user
user end point on the consumer side calls a method in the library to get data
But if the consumer is calling the user end point in test environment I want the library to hit the following API Url
for test http://api.test.userinformation.company.com/user
for beta http://api.beta.userinformation.company.com/user
As far as I understand the library is just a reference and is running within the consumer application. Library can for sure get the environment from the consumer, but I do not want the consumer having to specify the full URL that needs to be hit, since that would be the responsibility of the library to figure out.
Note: URL is not the only problem, I can solve that with environment switch within the library, I have some client secrets based on environments which I can neither store in the code nor checkin to source control.
Additional Information
(as per jfriend00's request in comments)
My library has a LibExecutionEngine class and one method in it, which is the entry point of the library:
export class LibExecutionEngine implements ExecutionEngine {
constructor(private environment: Environments, private trailLoader:
TrailLoader) {}
async GetUserInfo(
userId: string,
userGroupVersion: string
): Promise<UserInfo> {
return this.userLoader.loadUserInfo(userId, userGroupVersion)
}
}
export interface ExecutionEngine {
GetUserInfo(userId: string, userGroupVersion: string): Promise<UserInfo>
}
The consumer starts to use the library by creating an instance of the LibraryExecution then calling the getuserinfo for example. As you see the constructor for the class accepts an environment. Once I have the environment in the library, I need to somehow load the values for keys API Url, APIClientId and APIClientSecret from within the constructor. I know of two ways to do this:
Option 1
I could do something like this._configLoader.SetConfigVariables(environment) where configLoader.ts is a class that loads the specific configuration values from files({environment}.json), but this would mean I maintain the above mentioned URL variables and the respective clientid, clientsecret to be able to hit the URL in a json file, which I should not be checking in to source control.
Option 2
I could use dotenv npm package, and create one .env file where I define the three keys, and then the values are stored in the deployment configuration which works perfectly for an independently deployable application, but this is a library and doesn't run by itself in any environment.
Option 3
Accept a configuration object from the consumer, which means that the consumer of the library provides the URL, clientId, and clientSecret based on the environment for the library to access, but why should the responsibility of maintaining the necessary variables for library be put on the consumer?
Please suggest on how best to implement this.
So, I think I got some clarity. Lets call my Library L, and consuming app C1 and the API that the library makes a call out to get user info as A. All are internal applications in our org and have a OAuth setup to be able to communicate, our infosec team provides those clientids and secrets to individual applications, so I think my clarity here is: C1 would request their own clientid and clientsecret to hit A's URL, C1 would then pass in the three config values to the library, which the library uses to communicate with A. Same applies for some C2 in the future.
Which would mean that L somehow needs to accept a full configuration object with all required config values from its consumers C1, C2 etc.
Yes, that sounds like the proper approach. The library is just some code doing what it's told. It's the client in this case that had to fetch the clientid and clientsecret from the infosec team and maintain them and keep them safe and the client also has the URL that goes with them. So, the client passes all this into your library, ideally just once per instance and you then keep it in your instance data for the duration of that instance
Please let me know if openapi-request-validator nodejs library can be used to validate request against open api 3 spec yaml file. I had a look at express-openapi-validator, but my application does not use expressjs. My service is a lambda function (nodejs) deployed in aws.
I believe in your lambda function you can use openapi-request-validator, which already makes it's function signature very friendly to the openapi spec yaml file. What you can do:
Include the openapi spec yaml file in the zip file when deploying to AWS.
At runtime, load the yaml file and convert it into a Javascript object using some library (e.g. js-yaml).
write a simple function to do the following:
Look up the Javascript spec object based on the request path to find out related parameters, requestBody, schemas etc required by OpenAPIRequestValidator.
Transform the incoming API Gateway proxy event object (I assume it's proxy integration) into the format that validateRequest expects.
Then you will be able to new OpenAPIRequestValidator and call its validateRequest method to validate the transformed request object.
I have an HTTP triggered, NodeJs Azure Function, and I'm looking to remove the "X-Powered-By" header from my response, but have found no way to do so.
I've tried adding both this and this azure site extensions, but neither has worked for me,
Setting the response header manually, i.e. res.headers = { ['x-powered-by']: null } is ineffective.
Based on the comments made on this github issue: https://github.com/Azure/Azure-Functions/issues/290 it would seem that using either extension should have removed the headers you wanted.
Modifying the response headers will likely won't work as they are probably added further down the pipeline by the function host and not overridable, see:
Access Azure Function runtime settings
Azure functions recently removed the x-aspnet-version header, further removal of other headers is tracked as part of the azure-webjobs-script-sdk here
You should leave a comment on the github issue and you can further discuss with the team working on this.
There is an extension called Remove Custom Headers that works for Web Apps but not for functions that have their own resource group. So, what you can do is:
1. Create a regular Web App
2. Create a function and make sure you use the same Hosting Plan as the Web App (do not use Consumption).
3. Once the function is created, install the extension named: "Remove Custom Headers"
4. Restart the function and the headers (Server and X-Powered-By) should disappear.
I have a website with a Silverlight-enabled WCF service. The service works fine, and I can browse to the WSDL page in the browser with no problems.
Now, I am trying to create a client in a DLL. I need to create the whole client programmatically though, because it is being called in a DLL, which for whatever reason (by design?) won't read the ServiceModel section from its own config file.
So here is my code:
Dim endp As EndpointAddress = New EndpointAddress("http://www.mydomain.com/licensing/lic.svc")
Dim bind As WSHttpBinding = New WSHttpBinding()
Dim svc = New lnt.licClient(bind, endp)
Dim rsp = svc.CheckIt(key)
But when i call the svc.CheckIt method, i get the following error:
Content Type application/soap+xml; charset=utf-8 was not supported by service http://www.mydomain.com/licensing/lic.svc.
The client and service bindings may be mismatched.
{"The remote server returned an error: (415) Cannot process the message because the content type 'application/soap+xml; charset=utf-8' was not the expected type 'application/soap+msbin1'.."}
How do I properly create my client so that these are properly "matched"??
Thanks in advance!!!
Ah --- found it. The ServiceModel section in the website's web.config was set to customBinding. Changed it so it matched what the client was sending, and now it works beautifully.
I ran into this same issue. More spefically my fix was to update the type of bindings I was using. I was using wsHttpBindings instead of basicHttpBindings. This was causing failures as wsHttpBindings uses SOAP 1.2 while basicHttpBindings use SOAP 1.1 and the service I was using required SOAP 1.1
I had the same error. Service was compiling, client aplication too. Service reference in client aplication was updating reference succesfully. I've tried deleting and add reference once again and it was'nt helpfull. The problem was in removed interface in web service.
