本文主要是介绍使用携程apollo go版本app.properties的ip端口配置问题,希望对大家解决编程问题提供一定的参考价值,需要的开发者们随着小编来一起学习吧!
携程apollo, https://github.com/ctripcorp/apollo
背景
公司需要统一管理各个配置文件,而且apollo支持热发布以及不同环境不同集群配置等特征,所以选择使用apollo。
https://github.com/ctripcorp/apollo/wiki/Go%E3%80%81Python%E3%80%81NodeJS%E3%80%81PHP%E7%AD%89%E5%AE%A2%E6%88%B7%E7%AB%AF%E4%BD%BF%E7%94%A8%E6%8C%87%E5%8D%97
apollo的go客户端版本有3个。
3个版本的都进行了尝试。
zouyx/agollo的app.properties里面是namespacesName,是string类型
philchia/agollo的app.properties里面是namespaceNames, 是string类型的数组
shima-park/agollo的app.properties里面是namespaceNames, 是string类型的数组
app.properties如下
{"appId":"demo1","cluster":"default","namespaceNames":"apollo_demo","ip":"x.x.x.x:8070"
}
具体内容都是公司自己在apollo里面配置的,cluster默认就是default。
注意,我这里的ip的端口是8070,因为我让其他同事给我的地址就是http:/x.x.x.x:8070
导致我总是测试不通过的问题就在于这个ip的端口这里,这个端口应该是8080。
感觉写的乱糟糟的,所以如果你在测试go版本的时候请记得把ip后面的端口修改为8080.
根据打印的日志可见请求这个ip会返回给我一个html,把这个html拿出来以后其实是类似apollo的登录的页面。
而追踪代码发现,代码里面会把这个html转为json,进而转换为相应的结构体,由于这个html无法转为json,因此在
zouyx/agollo的app_config.go ##
syncServerIpListSuccessCallBack()这个方法总是报错,无法解析的json
在 philchia/agollo client.go中的##preload()
在shima-park/agollo 里面的agollo.go,报错如下:
LoadConfigFromNonCache Error invalid character '<' looking for beginning of value
以上3个错误都是由于配置文件app.properties里面的ip配置的端口不对导致的。由于端口不对,返回的是html,不是json格式的数据,就会导致解析出错。
发现问题是测试了携程apollo里面给的【演示环境】https://github.com/ctripcorp/apollo
地址是:106.12.25.204:8070,可以根据给定的账号密码登录去建立测试的项目
但是配置文件里面写的是8080端口。
一定要注意端口。
以下是测试的时候打印的Html
