I'm trying to set up a Web API and connect to it from a Xamarin Forms app. The API works, but the Xamarin Forms app wants the Web API to HTTPS.
So, I created a Self-Signed cert in IIS and installed my Web API using HTTPS and that cert.
When I click Browse in IIS, I get
There is a problem with this website’s security certificate.
The security certificate presented by this website was issued for a different website's address.
I click Continue and everything seems fine, and I can hit the API with Postman.
But when I try to hit it from my Xamarin Forms app, I get
Javax.Net.Ssl.SSLHandshakeException:
'java.security.cert.CertPathValidatorException: Trust anchor for certification path not found.'
I'm out of my league here. I really know nothing about certs and setting up HTTPS. Can someone help a blind man?

When your API is published, you should use a valid SSL certificate. Assuming it's public, you should be able to get a free certificate from "Let's Encrypt".
For development purposes, you should be able to extract the public key of your self-signed certificate, and use the ServicePointManager.ServerCertificateValidationCallback to compare the public key of the certificate to the public key you extracted.

Apparently, there are also options to enable calling HTTP services - again, you'd only want to do this in the debug build:

I'm just now getting back to this...
On that page you linked I read both the "With Shell Access" and the "Without Shell Access" sections and I'm thoroughly confused.
I created a .Net ASP.Net Web API and hosted it in IIS on my client's server. I'm not sure which of these two options I need.
The bottom line here is that I'm completely clueless about certifications and how to enable things in my Xamarin Forms app. I don't even know where to start learning. I've been Googling but the results are all over the board.

Wow. Hello, My name is Michael. Just call me Mike.

I'm working on setting up a .Net Framework Web API. I have created a Controller Base class:
public class _ApiControllerBase : ApiController
{
private string connectionString;
public IBizLayer BL { get; set; }
public _ApiControllerBase()
{
connectionString = Properties.Settings.Default.ConnectionString;
BL = new BizLayer(connectionString);
}
}
Next I created a Jobs Controller:
public class JobsController : _ApiControllerBase
{
public int AddJob([FromBody] JobEntity entity)
{
var newJobId = BL.AddJob(entity);
return newJobId;
}
public void DeleteJob(int jobId)
{
BL.DeleteJob(jobId);
}
public IEnumerable GetAllJobs()
{
List results = new List();
results = BL.GetJobsForProject(278).ToList();
return results;
}
public JobEntity GetJob(int Job)
{
return BL.GetJob(Job);
}
public List GetJobsForProject(int projectId)
{
List results = new List();
results = BL.GetJobsForProject(projectId).ToList();
return results;
}
public void UpdateJob([FromBody] JobEntity entity)
{
BL.UpdateJob(entity);
}
}
and my WebApiConfig:
public static class WebApiConfig
{
public static void Register(HttpConfiguration config)
{
config.MapHttpAttributeRoutes();
config.Routes.MapHttpRoute(
name: "DefaultApi",
routeTemplate: "api/{controller}/{action}/{id}",
defaults: new { id = RouteParameter.Optional }
);
}
}
I have tested all of this with Postman and it seems to work OK.
Any reason not to structure all my controllers this way? Any issues or problems I should be aware of?
Thanks

If you're not using it elsewhere within the base class, you can get rid of the private connectionString field.
I'd also be inclined to make the _ApiControllerBase class abstract.
public abstract class _ApiControllerBase : ApiController
{
public IBizLayer BL { get; set; }
protected _ApiControllerBase()
{
string connectionString = Properties.Settings.Default.ConnectionString;
BL = new BizLayer(connectionString);
}
}
Beyond that, if you're happy with the routes containing the entity name, then it's fine. But if you want a proper RESTful service, you'd want the routes to look more like:
GET /api/controller to return the list of all entities;GET /api/controller/{id} to return a specific entity;POST /api/controller to add a new entity;PUT (or PATCH) /api/controller/{id} to update an existing entity;DELETE /api/controller/{id} to delete an entity;
The GetJobsForProject action would be the exception to this pattern. I'd probably have it as: GET /api/projects/{projectId}/jobs

So to follow the REST standard, I would have to decorate each method with the Http Verbs?

How would this signature look in the API?

Yes. But you'd probably want to do that anyway - for example, you don't want actions which modify the data to be available via GET requests.
Kevin Marois wrote: How would this signature look in the API?
Depends on how you set up the routes. For example, if you don't have a RoutePrefix attribute on your controller:
public class JobsController : _ApiControllerBase
{
[HttpGet("api/projects/{projectId:int}/jobs")]
public List<JobEntity> GetJobsForProject(int projectId) { ... }
} However, my gut feeling is that this action would fit better as part of a ProjectsController:
[RoutePrefix("api/projects")
public class ProjectsController : _ApiControllerBase
{
[HttpGet("")]
public IEnumerable<ProjectEntity> GetAllProjects() { ... }
[HttpGet("{id:int}")]
public ProjectEntity GetProject(int id) { ... }
[HttpGet("{id:int}/jobs")]
public IEnumerable<JobEntity> GetJobsForProject(int id) { ... }
[HttpPost("")]
public int AddProject([FromBody] ProjectEntity entity) { ... }
[HttpPut("{id:int}")]
public void UpdateProject([FromBody] ProjectEntity entity) { ... }
[HttpDelete("{id:int}")]
public void DeleteProject(int id) { ... }
}

I have almost zero experience creating a Web API, so bear with me.
I opened VS2019 and created a new ASP.NET Web Application (.Net Framework). It comes with the standard Home and Values controllers.
I hit F5 and it ran. I then used Postman to verify passing "https://localhost:44312/api/Values". I get back the expected results. So far so good.
I then right clicked the project and chose "Publish" and published to a folder. I then copied the contents of the folder to the server and created a new Web Site in IIS pointing to my API and set the port to 44400. I clicked the Browse link in IIS and the browser opened. I added "/api/Values" to the end of the URL and got back this: Click: Here's the result.
I changed NOTHING in the app. Here's the Web.Config, which is what the error seems to be complaining about:
<?xml version="1.0" encoding="utf-8"?>

It looks like the configuration is locked down on your server.
Open IIS Manager, double-click on the "Feature Delegation" item in the "Management" group, and find the "Handler Mappings" item. Ensure that it's set to "Read/Write".

No, you've double-clicked on "Handler Mappings", not "Feature Delegation".
NB: "Feature delegation" is only available at the root, when you click on the server name. It won't be available within a specific site or application.

Hello,
This is my program with the obsolete WebRequest.
Who will help me to set this up with HttpClient.
Thanks in advance, Ger
public ToProgModel ProgCsv(Uri webSiteProg, ToProgModel prog, string complexProg)
{
string ProgTextString;
try
{
var AuthorisatorProg = _config.GetConnectionString("AuthorisatorProg");
var PasswordProg = _config.GetConnectionString("PasswordProg");
#pragma warning disable SYSLIB0014 // Type or member is obsolete
WebRequest webrequest = WebRequest.Create(webSiteProg);
#pragma warning restore SYSLIB0014 // Type or member is obsolete
SetBasicAuthHeader(webrequest, AuthorisatorProg, PasswordProg);
WebResponse webresponse = webrequest.GetResponse();
Stream webstream = webresponse.GetResponseStream();
StreamReader streamreader = new(webstream);
ProgTextString = streamreader.ReadToEnd();
webresponse.Close();
webresponse.Dispose();
streamreader.Dispose();
webstream.Dispose();
}
catch (HttpRequestException ex)
{
prog.Ret = $"Http response EX: {ex.Message}";
return null;
}
return prog;
}
public void SetBasicAuthHeader(WebRequest request, string userName, string userPassword)
{
string authInfo = userName + ":" + userPassword;
authInfo = Convert.ToBase64String(Encoding.Default.GetBytes(authInfo));
request.Headers["Authorization"] = "Basic " + authInfo;
}

For a start, you'll need to make your method async to use the HttpClient class. Which unfortunately means you'll need to make the calling method async, and so on - it's async all the way down.
At the basic level, your code would look something like this:
public async Task<ToProgModel> ProgCsvAsync(Uri webSiteProg, ToProgModel prog, string complextProg)
{
HttpClient client = new HttpClient();
SetBasicAuthHeader(client.DefaultRequestHeaders, AuthorisatorProg, PasswordProg);
using (HttpResponseMessage response = await client.GetAsync(webSiteProg))
{
if (!response.IsSuccessStatusCode)
{
prog.Ret = $"Http response EX: {response.StatusCode}";
return null;
}
string progTextString = await response.Content.ReadAsStringAsync();
...
return prog;
}
}
public void SetBasicAuthHeader(HttpRequestHeaders headers, string userName, string userPassword)
{
string authInfo = userName + ":" + userPassword;
authInfo = Convert.ToBase64String(Encoding.Default.GetBytes(authInfo));
headers.Authorization = new AuthenticationHeaderValue("Basic", authInfo);
} There are several improvements you can make to this - for example, using IHttpClientFactory[^] to manage the HttpClient instances.

Hi Homer, thanks for your response. But I don't see in IHttpClientFactory how to implement "Http Basic Authentication"
So as in my source "
SetBasicAuthHeader(webrequest, AuthorisatorProg, PasswordProg); "
|
|
|
|
|
I included an updated version of that method in my answer.
