Before diving into our ultimate goal, some foundational knowledge is required. Today I will do a practice for building a simple .Net WEB API.
Create a new project
Search “API” -> select ASP. NET Core Web API -> Next
Input project name “CustomerAPI” -> Next
Select .Net 8.0 (Long Term Support) -> Create
After creating the project, we can see visiual studio have already help us to generate some template files.
| File name | |
|---|---|
| launchSettings.json | project setting file |
| Program.cs | Main program file |
| CustomerAPI.http | Default http file |
| Now, we can test our project is work or not, simply press the start button (without debugging) | |
 |
A Swagger page will show up
We can check the respones data here
If not, I suggest go to chrome://flags/,
to Enable the “Allow invalid certificates for resources loaded from localhost”.
To allow browser access the localhost resource without certificates.
Or you can put the link {@CustomerAPI_HostAddress}/WeatherForecast to the search bar of the browser or Postman
For the request link, you can copy it from swagger
or go to launchSettings.json to find out the {@CustomerAPI_HostAddress}
under “profiles ->https”
We will our own date for API tomorrow.
