打开Startup.cs文件,在ConfigureServices方法中添加如下代码
public void ConfigureServices(IServiceCollection services){ services.AddMvc().AddJsonOptions(option=>{ //配置大小写问题,默认是首字母小写 option.SerializerSettings.ContractResolver = new Newtonsoft.Json.Serialization.DefaultContractResolver(); //配置序列化时时间格式为yyyy-MM-dd HH:mm:ss option.SerializerSettings.DateFormatString = "yyyy-MM-dd HH:mm:ss"; }) }
