kandi X-RAY | apollo-resolvers Summary
When standing up a GraphQL backend, one of the first design decisions you will undoubtedly need to make is how you will handle authentication, authorization, and errors. GraphQL resolvers present an entirely new paradigm that existing patterns for RESTful APIs fail to adequately address. Many developers end up writing duplicitous authorization checks in a vast majority of their resolver functions, as well as error handling logic to shield the client from encountering exposed internal errors. The goal of apollo-resolvers is to simplify the developer experience in working with GraphQL by abstracting away many of these decisions into a nice, expressive design pattern. apollo-resolvers provides a pattern for creating resolvers that work, essentially, like reactive middleware. By creating a chain of resolvers to satisfy individual parts of the overall problem, you are able to compose elegant streams that take a GraphQL request and bind it to a model method or some other form of business logic with authorization checks and error handling baked right in. With apollo-resolvers, data flows between composed resolvers in a natural order. Requests flow down from parent resolvers to child resolvers until they reach a point that a value is returned or the last child resolver is reached. Thrown errors bubble up from child resolvers to parent resolvers until an additional transformed error is either thrown or returned from an error callback or the last parent resolver is reached. In addition to the design pattern that apollo-resolvers provides for creating expressive and composible resolvers, there are also several provided helper methods and classes for handling context creation and cleanup, combining resolver definitions for presentation to graphql-tools via makeExecutableSchema, and more.

QUESTION
I am currently trying to create a web service application using Visual Studio 2022 ASP.NET Webforms application with a service reference. The goal is to take in information and store it as a text file on the local machine within the project folder so it is accessible by the web service on my local server.
I have successfully created the text files and can access them on my local machine, but when I navigate to the text file on my local server tree I get an HTTP Error 404.0 which is shown below. I need any user who accesses my server to be able to access the saved text files. I have tried to change security privileges on the folder and in my web.config file, but have not had any luck. I would appreciate any suggestions someone may have.
Here is my code for where I save the information as a text file.
...ANSWER
Answered 2022-Apr-03 at 20:04Ok, so you have to keep in mind how file mapping works with IIS.
Your code behind:
that is plane jane .net code. For the most part, any code, any file operations using full qualified windows path names. It like writing desktop software. For the most part, that means code behind can grab/use/look at any file on your computer.
However, in practice when you use a full blown web server running ISS (which you not really doing during development with VS and IIS express)? Often, for reasons of security, then ONLY files in the wwwroot folder is given permissions to the web server.
However, you working on your development computer - you are in a effect a super user, and you (and more important) your code thus as a result can read/write and grab and use ANY file on your computer.
So, keep above VERY clear in your mind:
Code behind = plane jane windows file operations.
Then we have requests from the web side of things (from a web page, or a URL you type into the web browser.
In that case, files are ONLY EVER mapped to the root of your project, and then sub folders.
So, you could up-load a file, and then with code behind save the file to ANY location on your computer.
However, web based file (urls) are ONLY ever mapped though the web site.
So, in effect, you have to consider your VS web project the root folder. And if you published to a real web server, that would be the case.
So, if you have the project folder, you can add a sub folder to that project.
Say, we add a folder called UpLoadFiles. (and make sure you use VS to add that folder). So we right click on the project and choose add->
So, you right click on the base project and add, like this:
So, that will simple create a sub folder in your project, you see it like this:
So, the folder MUST be in the root, or at the very least start in the root or base folder your project is.
So, for above, then with UpLoadFiles, then any WEB based path name (url) will be this:
QUESTION
I'm attempting to consume a SOAP Webservice using a WCF Web Service Reference.
I have been able to successfully consume the SOAP web service in a .NET 4.8 framework project using the System.Web.Servicees Web Service Reference. However I need to consume the web service in a .NET Core project. The WCF generated class from the WSDL is different than the .NET framework web service. It seems like you now have to use the generated WebServiceClient to interact with the web service.
I believe the web service requires basic authentication as I was able to authenticate using basic authentication in the .NET framework project.
Here is the error message I'm getting when I try to execute one of the web service's methods.

Answered 2022-Jan-20 at 21:47If you want queryParameters.get(assignee.name); to return a list, you can include the parameter more than once in the URL
http://localhost:9090/hello-todo/api/v1/todo/list?assignee.name=name1&assignee.name=name2
Or you can continue to have a single parameter (list?assignee.name=name1,name2) and split on ,, but you have to write the code to do that, and consider what to do when one of your names has a , character in it.
