Unpacking msgpack from respond in python

问题 I get the following error while trying msgpack.unpack : ExtraData: unpack(b) received extra data. Part of my code: r1=requests.get('http://localhost:3000/fs?path='+r.json()['object']) unp = msgpack.unpackb(r1.content) Can someone help with that? 回答1: The doc's aren't very clear about this, but msgpack.unpackb is a "one-shot" unpacker - you can't give it a larger stream with extra data in it. I assume that you are getting multiple msgpack objects and you can read them with msgpack.Unpacker as

Golang 中常见数据格式处理

数据格式介绍 数据格式是系统中数据交互不可缺少的内容 这里主要介绍 JSON 、 XML 、 MSGPack JSON json 是完全独立于语言的文本格式，是 k-v 的形式 name:zs 应用场景：前后端交互，系统间数据交互 json 使用 go 语言内置的 encoding/json 标准库 编码 json 使用 json.Marshal() 函数可以对一组数据进行 JSON 格式的编码 生成 json 格式 通过结构体生成 JSON 需要格式化的结构体中的字段必须是一个外部可调用的字段（首写字母大写），否则再 json 包中无法识别则读取不到 输出的 json key 是字段名称 package main import ( "encoding/json" "fmt" ) type Person struct { Name string Age int } func main() { p := &Person{"zs", 18} // 生成json b, err := json.Marshal(p) if err != nil { fmt.Println("json 序列化失败", err) return } fmt.Println(string(b)) // 格式化输出 b, err = json.MarshalIndent(p, "", " ") if err !=

msgpack库的神奇用法

一般来说，我们接收到消息，然后通过消息队列发送消息给worker的时候，会有些额外的字段，这些字段不属于实际的消息，我们想把实际的消息和发给worker的消息分开定义。这时候我们会把worker消息中一个字段定义为interface{}或者object，这个字段表示任意的实际消息。 type WorkerMsg struct { ID int Route string Msg interface{} // 实际消息 } 一切看起来很完美，但是问题来了，当我们用msgpack库decode消息到worker消息结构体的时候，这个Msg字段变成了一堆object的集合体，这时候，我们不得不再写一个函数把这些object，一个一个地复制到实际消息的结构体上，而这个函数是极其复杂的，很容易写错，而且性能也不好。 那么，我们还有更好的办法吗？其实我们可以这样写： package main import ( "bytes" "fmt" "github.com/vmihailenco/msgpack" ) type Abc struct { BB int Haha int } type Msg struct { ID int Msg interface{} } func main() { var msg Msg msg.Msg = Abc{BB: 2, Haha: 3} var buf

msgpack unserialising dict key strings to bytes

由 我是研究僧i 提交于 2020-01-14 12:37:27
问题 I am having issues with msgpack in python. It seems that when serialising a dict , if the keys are strings str , they are not unserialised properly and causing KeyError exceptions to be raised. Example: >>> import msgpack >>> d = dict() >>> value = 1234 >>> d['key'] = value >>> binary = msgpack.dumps(d) >>> new_d = msgpack.loads(binary) >>> new_d['key'] Traceback (most recent call last): File "<stdin>", line 1, in <module> KeyError: 'key' This is because the keys are not strings after calling

Node.js 是一个基于 Chrome V8 引擎的 JavaScript 运行环境。Node.js 使用了一个事件驱动、非阻塞式 I/O 的模型。如果你想创建自己的服务，那么Node.js是一个非常好的选择。今天就来介绍一下 Node.js 环境搭建及简单应用。 1.安装 Node.js 首先下载安装 Node.js，官方网站下载即可。 官方地址：https://nodejs.org/en/ 安装好后可以通过命令提示符查看安装版本是否正确，如下如所示： 这时你有可能会问到 npm 是什么？ 简单来说 npm 就是 Node.js 的包管理工具（package manager），Node.js 已经内置 npm，不用单独安装。具体可以参考廖雪峰老师的介绍，这里就不再展开说明。 廖雪峰老师介绍地址：https://www.liaoxuefeng.com/wiki/1022910821149312/1023025597810528 2.安装 WebStorm WebStorm 是jetbrains公司旗下一款JavaScript 开发工具。目前已经被广大中国JS开发者誉为“Web前端开发神器”、“最强大的HTML5编辑器”、“最智能的JavaScript IDE”等。这里我们将会用它来编写服务端代码，同样去官方网站下载即可，不过软件需要激活，具体激活方式可以自行百度，强力建议支持正版
