快递100的物流信息查询接口,官方提供了一些demo;还好官方提供的代码是.netcore版本写的,不过写的有点low;根据官方提供的代码,我按照.netcore 的风格重构了代码;核心代码如下:

                 QueryTrackReq query = new QueryTrackReq()
                 {
                     customer = config.KuaiDi100CustomerID,
                     sign = SignUtils.GetMD5(queryTrackParam.ToString() + config.KuaiDi100Key + config.KuaiDi100CustomerID),
                     param = queryTrackParam

                 var requestParam = ObjectToDictionaryUtils.ObjectToMap(query);
                 if (requestParam == null )
                 {
                     return null ;
                 }
                 
                  result = await HttpClientHelper.PostFormAsync<QueryTackResult>(_client, ApiInfoConstant.QUERY_URL, requestParam);
                 
             }
             catch (Exception ex)
             {
                 _logger.LogError(ex, $ "快递100实时快递查询接口异常:{ex.Message}" );
                 return null ;
             }
             return result;
         }
 
 
     }

上面的代码一眼看,就知道必须要使用依赖注入;我们看到 在构造函数里使用了HttpClient _client    这个东西;(因为要调用快递100的接口), 。

我们在startup里接着写:

?
1
services.AddScoped<KuaiDi100Helper>();

如上代码应该是最常用的注册方法;结果报错,错误信息如下:

System.AggregateException:“Some services are not able to be constructed (Error while validating the service descriptor 'ServiceType: MuXue.WeTao.Mall.Core.kuaidi100.KuaiDi100Helper Lifetime: Scoped ImplementationType: MuXue.WeTao.Mall.Core.kuaidi100.KuaiDi100Helper': Unable to resolve service for type 'System.Net.Http.HttpClient' while attempting to activate 'MuXue.WeTao.Mall.Core.kuaidi100.KuaiDi100Helper'.)”     InvalidOperationException: Unable to resolve service for type 'System.Net.Http.HttpClient' while attempting to activate 'MuXue.WeTao.Mall.Core.kuaidi100.KuaiDi100Helper'. 。

根据错误信息看,应该是httpclient出了问题了;找了很久才找到解决方法,修改startup里的注册方法 。

?
1
services.AddHttpClient<KuaiDi100Helper>(); //这样注入

这样就没问题了.
