asp.net core webapi项目

1.项目Startup文件 ConfiguratureService() 添加

public void ConfigureServices(IServiceCollection services)
{
      services.AddMvc(o =>
     {
           
           //统一输入内容格式
           o.InputFormatters.Insert(0, new RsInputFormatter());
           //统一的消息返回格式
           o.OutputFormatters.Insert(0, new RsOutputFormatter("yyyy-MM-dd"));
     }) 
}

2. api的消息将统一返回如下格式

{
  "success":true
  ,"code":200
  ,"msg":"your custom msg"
  ,"targetUrl":null
  ,"result":"your custom result object"
}

仅对请求是/api/开头的路径有效

POST请求，服务端参数定义[FormBody]Class model

客户端要保证 header中"Content-Type"："application/json;charset=utf-8"

$.ajax({
    url: '/api/password/change',
    type: 'put',
    data: JSON.stringify(data.field), //转字符，否则可能出现400
    contentType: 'application/json',  //不写可能出现415
    success: function(ret) {
        if (ret.success)
        {
            layer.msg(ret.msg, { icon: 1,time: 3000})
        }
        else
        {
            layer.msg(ret.msg, { icon: 2, time: 3000 });
        }
    },
    error: function(err) { }
});

客户端的参数如果是json，要转成字符串后发送到服务器，例var d=JSON.stringify(data);

如果想要对http 401，http 403的响应结果进行json格式化，可自定义类并继承IAuthorizationMiddlewareResultHandler 例：自定义类AuthorizationResultHandler

public class AuthorizationResultHandler : IAuthorizationMiddlewareResultHandler
{
    public async Task HandleAsync(RequestDelegate next, HttpContext context, AuthorizationPolicy policy, PolicyAuthorizationResult authorizeResult)
    {
        //await context.Response.WriteAsync(System.Text.Json.JsonSerializer.Serialize(new { msg = "用户未授权" }));
        await next(context);
    }
}

完成注册

services.AddSingleton<IAuthorizationMiddlewareResultHandler, AuthorizationResultHandler>();

asp.net core mvc项目

services.AddMvc()
    .AddJsonOptions(options => {
        //数据格式首字母小写
        options.JsonSerializerOptions.PropertyNamingPolicy =JsonNamingPolicy.CamelCase;
        //数据格式原样输出
        //options.JsonSerializerOptions.PropertyNamingPolicy = null;
        //取消Unicode编码
        options.JsonSerializerOptions.Encoder = JavaScriptEncoder.Create(UnicodeRanges.All);
        //忽略空值
        options.JsonSerializerOptions.IgnoreNullValues = true;
        //允许额外符号
        options.JsonSerializerOptions.AllowTrailingCommas = true;
        //反序列化过程中属性名称是否使用不区分大小写的比较
        options.JsonSerializerOptions.PropertyNameCaseInsensitive = false;
        //mvc返回日期格式
        options.JsonSerializerOptions.Converters.Add(new DateTimeConverter());
    });
