Fake权限验证小例子 - 敖毛毛 - 博客园
关于本地测试如何进行Fake权限验证 在我们使用swagger调试本地接口的时候,我们常常因为每次需要填写token而耽误工作,不可能每次调试的时候都去本地测试环境请求一个token进行验证吧。 上图可能是我们本地测试的时候需要填写的一个token位置,本地测试不方便。 那么怎么伪造权限验证通过呢? 有两个前置篇: https://www.cnblogs.com/aoximin/p/15582365.html https://www.cnblogs.com/aoximin/p/15613974.html 通过这两个前置篇的阅读,可能马上就能知道下面表达所在了,但是及时不看也没用过关系。 在.net 框架验证的时候呢? 我们可以加入自己的验证方案的。 public virtual AuthenticationBuilder AddScheme<TOptions, [DynamicallyAccessedMembers(DynamicallyAccessedMemberTypes.PublicConstructors)] THandler>(string...
自己动手实现一个轻量无负担的任务调度ScheduleTask - 万雅虎 - 博客园
至于任务调度这个基础功能,重要性不言而喻,大多数业务系统都会用到,世面上有很多成熟的三方库比如Quartz,Hangfire,Coravel 这里我们不讨论三方的库如何使用 而是从0开始自己制作一个简易的任务调度 技术栈用到了:BackgroundService和NCrontab库 第一步我们定义一个简单的任务约定,不干别的就是一个执行方法: public interface IScheduleTask { Task ExecuteAsync(); } public abstract class ScheduleTask : IScheduleTask { public virtual Task ExecuteAsync() { return Task.CompletedTask; } } 第二步定义特性标注任务执行周期等信的metadata [AttributeUsage(AttributeTargets.Class, AllowMultiple = true, Inherited = false)] public class...

Mastering CQRS Design Pattern with MediatR in C# .NET
INTRODUCTION The Command Query Responsibility Segregation (CQRS) pattern separates the concerns of read and write operations in an application by using separate models for handling commands (writing data) and queries (reading data). When implementing CQRS in C#, MediatR is a popular library that facilitates the implementation of the pattern by acting as a mediator between commands, queries, and their respective handlers. Key Components: Commands: Represent actions that mutate application state.
Modernize an existing Windows service to a .NET 8 gRPC service with Amazon ECS | Amazon Web Services
.NET on AWS Blog Introduction gRPC is a high-performance, cross-platform Remote Procedure Call (RPC) framework that allows for efficient communication between microservices. It was developed by Google and is now open-source. gRPC efficiently connects services in and across data centers with pluggable support for load balancing, tracing, health checking and authentication. For more information on gRPC, read the gRPC documentation.

【愚公系列】2023年09月 .NET CORE工具案例-HTTP请求之WebApiClientCore
前言 HTTP请求是客户端向服务器发送的请求信息。它包含请求行、请求头部和请求主体三部分。请求行包含请求的方法(GET、POST等),请求的URL和HTTP协议的版本。请求头部包含一些附加的信息,例如请求的主机名、浏览器类型、Cookie等。请求主体则是可选的,用于传输请求的数据。服务器收到HTTP请求后,根据请求信息进行相应的处理并返回响应结果。 一、HTTP请求组件WebApiClientCore WebApiClientCore是一个基于ASP.NET Core的轻量级WebAPI客户端开发框架。它提供了简单易用的API,使得开发人员可以轻松地创建和调用WebAPI,并且支持使用自定义的拦截器和过滤器来实现自定义的请求和响应处理。WebApiClientCore还支持与Swagger进行集成,以便于根据API文档生成客户端代码。该框架具有良好的可扩展性和可定制性,使得它在开发WebAPI客户端时很受欢迎。 WebApiClientCore是WebApiClient.JIT/AOT[1]的.NET...
Craft your own dynamic entity data source for ArcGIS Maps SDKs for Native Apps
If you’ve developed an app using ArcGIS Maps SDK for Native Apps, then you’ve probably worked with features and graphics. Have you met their geoelement cousin, dynamic entity? As part of the geoelement family, dynamic entities have attributes and geometry. They’re used to represent observations from a data stream to enable some really cool real-time workflows like: Tracking moving vehicles, such as delivery vehicles, commercial airline traffic, public transit, or emergency responders.

.netcore grpc服务端流方法详解
一、服务端流式处理概述 客户端向服务端发送请求,服务端可以将多个消息流式传输回调用方 和客户端流相反,客户端流发出请求,服务端可以传输一批消息给客户端,直至本次请求响应完全结束。 针对文件分段传输下载,该方式非常有用。 二、案例介绍 提供一个一元方法查询文件 提供一个文件流传输的服务端流式方法,进行文件流推送 三、服务端配置(注意:grpc相关配置参考我之前的文章) // 1.提供公共的实体proto文件 // 2.服务引用对应的proto文件 // 3.定义三个客户流方法 syntax = "proto3"; option csharp_namespace = "GrpcProject"; package grpc.serviceing; // 服务端流对应的请求流和响应流 message FileInfoRequest { string fileName = 1; } message FileInfoResponse { string fileName = 1; int64 fileSize = 2; string extension = 3; } message...
Test Your REST APIs Using Insomnia REST Client
Over the past few years, APIs evolved to become the center of software development. You can take advantage of APIs to enable communication between systems and the data exchange between them. Today's applications thrive on a lot on APIs - most of today's applications are API-based. You must test your APIs before releasing them for the clients or end-users to consume.
【愚公系列】2023年05月 .NET CORE工具案例-基于MediatR的CQRS模式
(文章目录) 1.什么是CQRS模式 CQRS 是一种与领域驱动设计 (DDD) 和事件溯源相关的架构模式,本质上是一种读写逻辑分离的机制。 CQRS可以有两种实现方式。 1、CQ两端数据库共享,只是在上层代码上分离。 这样做的好处是可以让我们的代码读写分离,更容易维护,而且不存在CQ两端的数据一致性问题, 因为是共享一个数据库的。 2、CQ两端不仅代码分离,数据库也分离,然后Q端数据由C端同步过来。 同步方式有两种:同步或异步,如果需要CQ两端的强一致性,则需要用同步;如果能接受CQ两端数据的最终一致性,则可以使用异步。 C端可以采用EventSourcing(简称ES)模式,所有C端的最新数据全部用DomainEvent表达即可。 而要查询显示用的数据,则从Q端的ReadDB(关系型数据库)查询即可。 2.中介者模式 中介者模式属于行为型模式,它包装了一系列对象相互作用的方式,使得这些对象不必相互明显作用,从而使它们可以松散耦合。 当某些对象之间的作用发生改变时,不会立即影响其他的一些对象之间的作用,保证这些作用可以彼此独立的变化。...

.Net C# MemoryCache 缓存
缓存是一种开发时常用的性能优化手段,.Net自带内存缓存(MemoryCache)可以很方便的使用,下面列出简单用法。 首先通过NuGet添加 Microsoft.Extensions.Hosting、Microsoft.Extensions.Caching.Memory 这两个包。 添加命令: Install-Package Microsoft.Extensions.Caching.Memory Install-Package Microsoft.Extensions.Hosting 向缓存中添加数据: memoryCache.Set(dog.Name, dog, options); 从缓存获取数据(可以直接使用泛型方法指定返回类型): memoryCache.Get<Dog>(key); 添加时可以使用 await memoryCache.GetOrCreateAsync()方法完成,该方法可以在缓存中没有数据时另外处理获取数据的方式,并将结果添加进缓存中。 参考代码: internal class CacheDemo { //该集合当做数据源 static...
Cake Frosting: More Maintainable C# DevOps
This week Cake V1.0 was released and with it: an upgrade to Frosting, a more robust technique for writing DevOps in a language the whole team can understand. The timing is fantastic, because last week I just posted The One Thing I Wish I'd Known Before Using Cake, in which I warned of uncontrolled growth of the more traditional build.cake file. The solution I offered there still stands, however Cake Frosting offers an even better solution for modularity, encapsulation and maintainability.
How To Write Decoupled Code with MediatR: The Mediator Pattern
@samwalpoleSam Walpole Fullstack .NET and JavaScript web developer. Coding teacher and advocate I recently wrote a blog post introducing some of my favourite NuGet packages: My Top 4 NuGet Packages for ASP.NET Core. In that post, I briefly introduced a package called MediatR. Today, I will dedicate this post to revisiting MediatR in further detail. What is MediatR? MediatR is an implementation of the mediator pattern.
How to await an asynchronous method in Emit code
Preface First of all, immediately explain why there is such a pseudo-titled Demo essay? It’s not that I have a misunderstanding of knowledge or want to mislead others Because everyone knows that emit writes are synchronous methods, it is impossible to await, at least it has not provided corresponding functions for so many years.
