go - 从外部命令读取错误 : fatal error all goroutines are asleep - deadlock

我想用Python将mime/multipart消息写入标准输出,然后使用mime/multipart包在Golang中读取该消息。这只是一个学习练习。我尝试模拟thisexample.输出.py#!/usr/bin/envpython2.7importsyss="--foo\r\nFoo:one\r\n\r\nAsection\r\n"+"--foo\r\nFoo:two\r\n\r\nAndanother\r\n"+"--foo--\r\n"prints主.gopackagemainimport("io""os/exec""mime/multipart""log""io/iouti

elasticsearch8.5.2 报错(SearchPhaseExecutionException: all shards failed)

一、问题logstash突然无法对elasticsearch服务进行读写操作了,提示elasticsearch的地址有问题,检测elasticsearch发现端口存在。查看日志发现有报错。二、问题原因有一些索引的数据损坏了三、解决官网文档:https://www.elastic.co/guide/cn/elasticsearch/guide/cn/_cluster_health.html1、查看索引信息curl-XGET'http://localhost:9200/_cluster/health?pretty=true'{"cluster_name":"test","status":"yell

arrays - 去 : how to Assign all elements in 2 by 2 array of variable size?

我在使用GO使用文本文件中的矩阵填充二维数组时遇到问题。我遇到的主要问题是创建一个二维数组,因为我必须计算数组的维度,而GO似乎不接受数组维度中的VAR:nb_lines=numberoflineofthearraynb_col=numberofcolumnsofthearray//readmatrixfromfilewhole_file,_:=ioutil.ReadFile("test2.txt")//geteachlineofthefileintab_whole_filetab_whole_file:=strings.Split(string(whole_file),"\n")//

go - golang 中的 Catch-All URL

我打算用golang重写我的flask应用程序。我正在尝试为golang中的catchall路由找到一个很好的例子,类似于我下面的flask应用程序。fromflaskimportFlask,request,Responseapp=Flask(__name__)@app.route('/')defhello_world():return'HelloWorld!Iamrunningonport'+str(port)@app.route('/health')defhealth():return'OK'@app.route('/es',defaults={'path':''})@app.ro
