.net core3.0 wei API,默认返回的json序列化改成了System.text.json,
默认的序列化发现在序列树形的数据会出现内存溢出,要怎么配置默认的

.net core如何解密.net framework System.Web.Security.MachineKey.Protect()加密的密文?
最近在做.net framework到.net core的代码重构,然后发现.net core里面已经没有System.Web.Security.MachineKey.Protect()这个方法了,取而代之的是IDataProtector 以前的.net framework的数据通过System.Web.Security.MachineKey.Protect()进行加密, 对应的web.config配置如下: <system.web> <!-- DEV & QA --> <machineKey validationKey="xxxxx" decryptionKey="xxxxxxxx" validation="SHA1" decryption="3DES"/> </system.web> 加密后的密文如下: QEfVpMPsSbAD6V3w5NnSWCi4uHnvHjvHtSJsuNYi+GqnYRT1R9TJSS5hxHFq3a+4NuR9UPjlBbgsoj7lRk08PajDLFM= machineKey validationKey="xxxxx" decryptionKey="xxxxxxxx" validation="SHA1" decryption="3DES validationKey,decryptionKey都有,如何能在.net core中通过相应的validationKey,decryptionKey把上述的密文正确解密出来~ 求大神帮助~
.net core 3.0 winform 有个问题就是再项目创建之后会产生system 丢失 或者版本号错误 引用之后无效?

.Net Core API的Post动作不能使用[FromBody] dynamic data写法了?
/// <summary> /// Post /// </summary> /// <param name="data">{'empno':'123456'}</param> /// <returns></returns> [HttpPost("PostEmpno")] public dynamic PostEmpno([FromBody] dynamic data) { string emp = data.empno ; return emp; } 为什么接受到的参数是会是这样的? ValueKind = Object : "{"empno":"FE688"}" string emp = data.empno 直接报错 Message "'System.Text.Json.JsonElement' does not contain a definition for 'empno'" string 以前.Net framework API直接使用dynamic的时候,可以data.empno获取到值,现在只能提前定义Model了? 请教如何接受dynamic动态类

【小白提问】.net core 2.2 发布到IIS后 webapi 404错误
环境 .net core 2.2,ef core, 前台页面lay-ui 本机测试都正常,发布到IIS后,MVC 绑定数据都正常访问正常,Layui table ajax调用的都报404错误。 ![图片说明](https://img-ask.csdn.net/upload/201912/03/1575366379_942361.png) ![图片说明](https://img-ask.csdn.net/upload/201912/03/1575366361_646674.png) 接口代码: ``` [HttpPost] public IActionResult List() { _logger.LogInformation("==================={path}", HttpContext.Request.Path); Logger.Info(HttpContext.Request.Path); var result = new Object(); var success = new object(); var msg = new object(); var data = new object(); var code = 0; try { data = _context.ItemsLending.ToList(); Logger.Info(JsonConvert.SerializeObject(data));//此处调用日志记录函数记录日志 } catch (Exception e) { _logger.LogError("==================={path},{err}", HttpContext.Request.Path,e.Message); Logger.Info(e.Message);//此处调用日志记录函数记录日志 } result = (new { code, msg, data }); return Json(result); } ``` 尝试加了Log,发现完全没有调用这个接口,只有打开页面的log js ``` table.render({ elem: '#LendingList' , url: '/Lending/List/' , cellMinWidth: 80 //全局定义常规单元格的最小宽度,layui 2.2.1 新增 , method: 'post' , cols: [[ { field: 'id', title: 'Id', sort: true, templet: '#detail' } , { field: 'staffId', title: 'Staff ID' } , { field: 'item', title: 'Item' } , { field: 'lendingDate', title: 'Lending date', sort: true } , { field: 'preReturnDate', title: 'Pre return date' } , { field: 'returnDate', title: 'Return date' } , { field: 'status', title: 'Status' } , { field: 'remarks', title: 'Remarks', width: '20%', minWidth: 100 } //minWidth:局部定义当前单元格的最小宽度,layui 2.2.1 新增 ]] }); ```
SpringMvc中使用json报错415:源服务器拒绝服务请求,因为有效负载的格式在目标资源上此方法不支持。
已经导入了jackson依赖 ``` <dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-databind</artifactId> <version>2.9.9</version> </dependency> <dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-core</artifactId> <version>2.9.9</version> </dependency> <dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-annotations</artifactId> <version>2.9.9</version> </dependency> ``` 简单java类 ``` public class item implements Serializable { private String name; public String getName() { return name; } public void setName(String name) { this.name = name; } public item(String name) { this.name = name; } } ``` 控制器类 ``` @RequestMapping(path = "/testAjax",method = RequestMethod.POST) @ResponseBody public void testAjax(@RequestBody item test){ System.out.println("testAjax方法执行了....."); System.out.println(test); } ``` ajax请求 ``` $.ajax({ url:"/test/testAjax", contentType:"application/json;charset=UTF-8", data:JSON.stringify({"name":"shadow"}), dataType:"json", type:"POST", success:function (data) { alert("username"+ data.name); }, }); ```
java.net.ConnectException: Connection refused: connect
昨天遇到了这个错,到现在没解决,求大佬帮助 1.服务器安装了一个8082的项目,网页访问服务器ip:8082没有任何问题 2.本地装了个node,启动了一个前端项目 localhost:3000,后端接口配的就是http://服务器ip:8082 然后本地掉服务器接口就一直报 java.net.ConnectException: Connection refused: connect, 3.前端是通过jsonp掉的接口 之前都是好的,请问怎么解决啊 spring boot 项目 服务器windows的,防火墙是关闭的,端口也没占用 错误信息 ``` java.net.ConnectException: Connection refused: connect at java.net.DualStackPlainSocketImpl.connect0(Native Method)

.net core 2.1限制方法请求最长时间。
1、问题描述: 在.net core项目中我们用的是2.1版本的。现在请求越来越多,有些处理不过来。所以我们就想,如果超过3秒还没处理完的就结束它的请求。 2、网上的方案: 在ASP.NET Core项目发布后生成的web.config文件中,加入时间限制配置 requestTimeout="00:20:00": ``` <?xml version="1.0" encoding="utf-8"?> <configuration> <system.webServer> <handlers> <add name="aspNetCore" path="*" verb="*" modules="AspNetCoreModule" resourceType="Unspecified"/> </handlers> <aspNetCore requestTimeout="00:20:00" processPath="%LAUNCHER_PATH%" arguments="%LAUNCHER_ARGS%" stdoutLogEnabled="false" stdoutLogFile=".\logs\stdout" forwardWindowsAuthToken="false"/> </system.webServer> </configuration> ``` 但是这个操作在.net core 2.1中修改配置不起作用。具体不是到什么原因。下面是我的配置信息![图片说明](https://img-ask.csdn.net/upload/201904/19/1555642627_331606.png) 当前思考的方向: .net core2.1中是否能在每个请求到controller中,是否共享线程的? **如果的多线程**能否计算该线程处理controller方法的时间 并且达到一定时间结束该线程。**如果共享的单线程**,又有什么方法能够设置controller中方法允许的最长处理时间呢? 欢迎各位发表一下意见。
.net core上利用nodeservice处理js代码,当传入json字符串解析出错
直接上代码 这是我的controller代码 ``` [HttpGet] public async Task<string> Get() { //CheckUser(); string str = "{\"name\":\"json\"}"; var msg = await _nodeServices.InvokeExportAsync<string>("hello", "f2", str); return msg; } ``` 这是我的js代码 ``` module.exports.f2 = function (callback, str) { var json = JSON.parse(str); json.name = "jsonjson"; callback(null, json); }; ``` 但是利用postman调用时总是出现 sonReaderException: Unexpected character encountered while parsing value: {. Path '', line 1, position 1.错误 实在是不知道为什么出错,是nodeService的问题吗

.net core webapi异步接口调用数据库for里面使用await不等待,返回空(有时候有返回值)

进程通信方式总结与盘点
​ 进程通信是指进程之间的信息交换。这里需要和进程同步做一下区分,进程同步控制多个进程按一定顺序执行,进程通信是一种手段,而进程同步是目标。从某方面来讲,进程通信可以解决进程同步问题。 ​ 首先回顾下我们前面博文中讲到的信号量机制,为了实现进程的互斥与同步,需要在进程间交换一定的信息,因此信号量机制也可以被归为进程通信的一种方式,但是也被称为低级进程通信,主要原因为: 效率低:一次只可操作少量的...

点击“技术领导力”关注∆  每天早上8:30推送 作者| Mr.K   编辑| Emma 来源| 技术领导力(ID:jishulingdaoli) 前天的推文《冯唐:职场人35岁以后,方法论比经验重要》,收到了不少读者的反馈,觉得挺受启发。其实,冯唐写了不少关于职场方面的文章,都挺不错的。可惜大家只记住了“春风十里不如你”、“如何避免成为油腻腻的中年人”等不那么正经的文章。 本文整理了冯
程序员该看的几部电影
##1、骇客帝国(1999) 概念:在线/离线,递归,循环,矩阵等 剧情简介: 不久的将来,网络黑客尼奥对这个看似正常的现实世界产生了怀疑。 他结识了黑客崔妮蒂,并见到了黑客组织的首领墨菲斯。 墨菲斯告诉他,现实世界其实是由一个名叫“母体”的计算机人工智能系统控制,人们就像他们饲养的动物,没有自由和思想,而尼奥就是能够拯救人类的救世主。 可是,救赎之路从来都不会一帆风顺,到底哪里才是真实的世界?
入职阿里5年,他如何破解“技术债”?
简介: 作者 | 都铎 作为一名技术人,你常常会听到这样的话: “先快速上线” “没时间改” “再缓一缓吧” “以后再解决” “先用临时方案处理” …… 当你埋下的坑越来越多,不知道哪天哪位同学就会踩上一颗雷。特别赞同“人最大的恐惧就是未知,当技术债可说不可见的时候,才是最让人不想解决的时候。” 作为一个程序员,我们反对复制粘贴,但是我们经常会见到相似的代码,相同的二方包,甚至整个代码...

作为一个程序员,CPU的这些硬核知识你必须会!
CPU对每个程序员来说,是个既熟悉又陌生的东西? 如果你只知道CPU是中央处理器的话,那可能对你并没有什么用,那么作为程序员的我们,必须要搞懂的就是CPU这家伙是如何运行的,尤其要搞懂它里面的寄存器是怎么一回事,因为这将让你从底层明白程序的运行机制。 随我一起,来好好认识下CPU这货吧 把CPU掰开来看 对于CPU来说,我们首先就要搞明白它是怎么回事,也就是它的内部构造,当然,CPU那么牛的一个东

2020年1月17日,国家统计局发布了2019年国民经济报告,报告中指出我国人口突破14亿。 猪哥的朋友圈被14亿人口刷屏,但是很多人并没有看到我国复杂的人口问题:老龄化、男女比例失衡、生育率下降、人口红利下降等。 今天我们就来分析一下我们国家的人口数据吧! 一、背景 1.人口突破14亿 2020年1月17日,国家统计局发布了 2019年国民经济报告 ,报告中指出:年末中国大陆总人口(包括31个
在家远程办公效率低?那你一定要收好这个「在家办公」神器!
相信大家都已经收到国务院延长春节假期的消息,接下来,在家远程办公可能将会持续一段时间。 但是问题来了。远程办公不是人在电脑前就当坐班了,相反,对于沟通效率,文件协作,以及信息安全都有着极高的要求。有着非常多的挑战,比如: 1在异地互相不见面的会议上,如何提高沟通效率? 2文件之间的来往反馈如何做到及时性?如何保证信息安全? 3如何规划安排每天工作,以及如何进行成果验收? ......
作为一个程序员,内存和磁盘的这些事情,你不得不知道啊!!!
截止目前,我已经分享了如下几篇文章: 一个程序在计算机中是如何运行的?超级干货!!! 作为一个程序员,CPU的这些硬核知识你必须会! 作为一个程序员,内存的这些硬核知识你必须懂! 这些知识可以说是我们之前都不太重视的基础知识,可能大家在上大学的时候都学习过了,但是嘞,当时由于老师讲解的没那么有趣,又加上这些知识本身就比较枯燥,所以嘞,大家当初几乎等于没学。 再说啦,学习这些,也看不出来有什么用啊!
2020年的1月,我辞掉了我的第一份工作
其实,这篇文章,我应该早点写的,毕竟现在已经2月份了。不过一些其它原因,或者是我的惰性、还有一些迷茫的念头,让自己迟迟没有试着写一点东西,记录下,或者说是总结下自己前3年的工作上的经历、学习的过程。 我自己知道的,在写自己的博客方面,我的文笔很一般,非技术类的文章不想去写;另外我又是一个还比较热衷于技术的人,而平常复杂一点的东西,如果想写文章写的清楚点,是需要足够...

Java坑人面试题系列: 包装类(中级难度)
Java Magazine上面有一个专门坑人的面试题系列: https://blogs.oracle.com/javamagazine/quiz-2。 这些问题的设计宗旨,主要是测试面试者对Java语言的了解程度,而不是为了用弯弯绕绕的手段把面试者搞蒙。 如果你看过往期的问题,就会发现每一个都不简单。 这些试题模拟了认证考试中的一些难题。 而 “中级(intermediate)” 和 “高级(ad

你也能看懂的:蒙特卡罗方法
蒙特卡罗方法,也称统计模拟方法,是1940年代中期由于科学技术的发展和电子计算机的发明,而提出的一种以概率统计理论为指导的数值计算方法。是指使用随机数(或更常见的伪随机数)来解决很多计算问题的方法 蒙特卡罗方法可以粗略地分成两类:一类是所求解的问题本身具有内在的随机性,借助计算机的运算能力可以直接模拟这种随机的过程。另一种类型是所求解问题可以转化为某种随机分布的特征数,比如随机事件出现的概率,或...
