RapidityHttp是对HttpClient的包装，内含重试，熔断降级，请求缓存，请求日志，用于简化/快速对接第三方RestApi。(RapidityHttp is a wrapper for HttpClient, including retry, blowdown, cache, request log, purpose is convenient, fast docking RestApi)
配置服务及注入：
public void ConfigureServices(IServiceCollection services)
{
services.AddRapidityHttp().ConfigRecordStore<TextInvokeRecordStore>().AddHttpService("wechat", config =>
{
config.BaseAddress = "https://api.weixin.qq.com/";
config.Timeout = 60;
config.Item.ContentType = "application/json";
config.Item.DefaultHeaders.Add("customHeader", "fromtest");
}).For<ITokenService>();
services.BuildProxy(); //生成服务代理
services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_2);
}
服务定义时只需定义接口实现IHttpService，或者使用HttpServiceAttribute标签, 组件自动生成接口代理实现类
1.继承自IHttpService接口
public interface ITokenService : IHttpService
{
[Get("/cgi-bin/token")]
Task<AccessToken> GetToken([Query] string appid, [Query]string secret, [Query(Name = "grant_type")]string grantType = "client_credential");
[Get("/cgi-bin/getcallbackip?access_token={token}")]
Task<ResponseWrapper<IpList>> GetIpListAsync([Query] string token);
[Post("/cgi-bin/message/template/send?access_token={token}")]
[Header("header:{header}")]
void SendTemplateMsg(string token, string header, [Body(CanNull = false)] MessageTemplate template);
}
2. 使用HttpServiceAttribute标签
[HttpService]
public interface ITokenService
{
[Get("/cgi-bin/token")]
Task<AccessToken> GetToken([Query] string appid, [Query]string secret, [Query(Name = "grant_type")]string grantType = "client_credential");
[Get("/cgi-bin/getcallbackip?access_token={token}")]
Task<ResponseWrapper<IpList>> GetIpListAsync([Query] string token);
[Post("/cgi-bin/message/template/send?access_token={token}")]
[Header("header:{header}")]
void SendTemplateMsg(string token, string header, [Body(CanNull = false)] MessageTemplate template);
}
使用服务：
[ApiController]
public class TokenController : Controller
{
private readonly ITokenService _tokenService;
public TokenController(ITokenService tokenService)
{
_tokenService = tokenService;
}
// GET api/values
[HttpGet]
public async Task<AccessToken> Get()
{
var token = await _tokenService.GetToken("**********", "**********");
return token;
}
}
