How to connect Solr with .NET5
This is a very basic sample to show Solr & .NET5 integration.
Nuget Packages
- SolrNet.Core
- SolrNet.Microsoft.DependencyInjection
Init Solr Service in Startup.cs
var credentials = Encoding.ASCII.GetBytes("username:password");
var credentialsBase64 = Convert.ToBase64String(credentials);
services.AddSolrNet<WeatherForecast>("https://solr-server-ip:port/solr/name", options =>
{
options.HttpClient.DefaultRequestHeaders.Authorization = new System.Net.Http.Headers.AuthenticationHeaderValue("Basic", credentialsBase64);
});Model
public class WeatherForecast
{
[SolrUniqueKey("id")]
public string Id { get; set; }
[SolrField("temperature")]
public int Temperature { get; set; }
[SolrField("summary")]
public string Summary { get; set; }
}Api Controller
private readonly ILogger<WeatherForecastController> _logger;
private readonly ISolrOperations<WeatherForecast> _solr;
public WeatherForecastController(ILogger<WeatherForecastController> logger, ISolrOperations<WeatherForecast> solr)
{
_logger = logger;
_solr = solr;
}Query
[HttpGet]
public async Task<IActionResult> QueryTemperatureAsync([FromQuery]string parameter)
{
// sample
// parameter = "Freezing";
_logger.LogInformation("Search: " + parameter);
SolrQueryResults<WeatherForecast> results = await _solr.QueryAsync(new SolrQuery($"summary: {parameter}"));
return Ok(results);
}Add
[HttpPost]
public async Task<IActionResult> AddTemperatureAsync([FromQuery]WeatherForecast weather)
{
_logger.LogInformation("Add: " + weather.Summary);
// sample
//Random rng = new();
//WeatherForecast weather = new()
//{
// Id = "1",
// Summary = Summaries[rng.Next(Summaries.Length)],
// Temperature = 10
//};
await _solr.AddAsync(weather);
await _solr.CommitAsync();
return Ok(weather);
