问题 It's hard for me to describe the problem precisely. Let me show the code below: I have a function in C : int foo(char *deviceID){ char a[]="abc"; deviceID=a; return 1; } Obviously I pass the char*deviceID arguments to be changed in this function, just ignore the return integer, what I want is to get the value of deviceID ; In Go : func getID() string{ var b []byte C.foo((*C.char)(unsafe.Pointer(&b))) return string(b) } But it seems I got nothing. Can anyone help me find out the problem? 回答1:

问题 I am currently using the $pull operator successfully to delete an item in an array. The Data structure looks like this { _id: 234, comments: [{id:1},{id:2},{id:3}] } My change struct change := mgo.Change{ Update: bson.M{ "$pull": bson.M{ "comments": bson.M{ "id": c.Id, }, }, }, ReturnNew: true, } and my mongo command test, err := cs.Find(bson.M{"_id": 234}).Apply(change, nil) In the mongo shell, simulating the same command would return useful meta information On success WriteResult({

outlier异常值检验原理和处理方法

An outlier is any data point that is distinctly different from the rest of your data points. When you’re looking at a variable that is relatively normally distributed, you can think of outliers as anything that falls 3 or more standard deviations from its mean. While this will suffice as a working definition, keep in mind that there’s no golden rule for defining what an outlier is.

人工智能在很多领域为人类带来了便利,自动驾驶便是其中最火热的领域之一。 由于不容易体验到,不少人都觉得自动驾驶技术离现实生活还有一段距离。 但事实情况却并非如此,在技术和法规不断发展完善的背景下,自动驾驶技术已经进入了我们的生活。 早在2018年底,百度Apollo自动驾驶全场景车就已经在长沙亮相,并完成高速场景自动驾驶车路协同演示。 去年9月,百度便在长沙宣布,即日起,普通长沙市民可申请试乘体验自动驾驶出租车。 今年10月11日,百度官方宣布,即日起,百度自动驾驶出租车服务在北京全面开放。 北京的朋友们可在海淀区、亦庄的自动驾驶出租车站点,无需预约,直接下单免费试乘自动驾驶出租车服务。 此次的自动驾驶出租车活动时间为10月10日-11月6日,运营时段为周一至周日的10:00-16:00,法定节假日除外。 若想体验免费自动驾驶出租车的话,大家可以通过以下两种方式打车: 1、打开百度地图,选择“打车-自动驾驶-选择上下车站点-选择乘车人数-立即呼叫Apollo GO”等选项后,就能直接约车。 2、下载并打开Apollo GO的App,选择上下车站点 - 选择乘车人数 - 立即呼叫Apollo GO。 根据百度官方介绍,用户参与乘车体验后,还可在工作人员处领取礼品。 需要再次提醒大家的是,当前的百度自动驾驶出租车服务体验,上下车均需要在指定的数十个站点。 如果不清楚指定乘车点

SSE broken after deploying with Kubernetes and connecting via Ingress

有些话、适合烂在心里 提交于 2021-02-10 08:44:08
问题 I've a ReactJS client which uses EventStream and a golang backend which implements SSE. Everything seemed to work when I connected my browser to the backend running on localhost, as well as when my backend was running on k8s with port forwarding. As soon as I created an ingress with a hostname (so that I don't have to port-forward all the time) SSE stopped working. I still see that the client sends the request and this request is received and registered by the backend. However, when and event

Go语言开发分布式聊天室

穿精又带淫゛_ 提交于 2021-02-10 07:37:11
声明 我是一个刚学go语言的菜鸟,还没有资格谈论什么技术分享,只是为了展示fooking的实际应用,同时把我用go写的聊天室代码贴出来供大家消遣,如果有入不了各位法眼的代码,望轻喷。该聊天室基于fooking,而业务代码是采用Go + Fastcgi。 完整的源代码在 https://github.com/scgywx/fooking/blob/master/example/chat/gateway.go ,全代码200多行,去掉router部分代码,实际逻辑代码只有170来行,逻辑简单,功能强大。 详解 聊天服务器的入口main函数里有3个IP和端口配置,分别是Chat服务器、Router服务器和Redis服务器。 func main() { listener, _ := net.Listen("tcp", "0.0.0.0:9001")//Chat服务器配置 srv := newChatServer("test:9010", "test:6379");//Router配置与Redis配置 fcgi.Serve(listener, srv) } Chat服务器就是实现主要的聊天逻辑,Router服务器是用于转发消息,Redis用来存储用户信息。上面我讲过这个聊天室是基于fooking,所以客户端不是直接与go通信,而是透过fooking来访问的

How to get the number of elements in an unbuffered channel

回眸只為那壹抹淺笑 提交于 2021-02-10 07:29:07
问题 I am in a situation where my program is deadlocking and I want to debug this and tell how many elements are in an unbuffered channel, is there any way to do this in Go? The following code does not output a 2 as I would expect (further it deadlocks, which is also something I cannot find a reason for) package main import "fmt" func main() { channel := make(chan string) done_channel := make(chan bool) go func() { channel <- "value" channel <- "value" fmt.Println(len(channel)) done_channel <-
