Java has some embedded features to parse binary data (for instance ByteBuffer), but sometime it is needed to work on bit level and describe binary structures through some DSL(domain specific language). I was im

1、form-data: 就是http请求中的multipart/form-data,它会将表单的数据处理为一条消息,以标签为单元,用分隔符分开。既可以上传键值对,也可以上传文件。当上传的字段是文件时,会有Content-Type来说明文件类型;content-disposition,用来说明字段的一些信息;由于有boundary隔离,所以multipart/form-data既可以上传文件,也可...

python加载PCD文件 什么是PCD文件 Point Cloud Data,中文译为点云数据(简称PCD),它是一种存储点云数据的文件格式。其实文件格式有很多种,但是为什么还要重新定义一种新的文件格式呢?那是因为它们都无法满足PCL(Point Cloud Library)的数据处理需求。在PCD格式被定义之前,表示激光扫描仪获取的点云、任意多变形...
datadict = {1 : "小明", "age" : 18,}; print(datadict[Key]); 取值,取值的时候,也是索引使用.不过索引是我们的key,比如我们的key是1,那么就是1 print(datadict["age"]); 输入的是key,不是索引. key当索引取寻找值. 修改: datadict[key] = value; 语法 datadict["age"] = 10; 将age的...
