python read file from a web URL

由 耗尽温柔 提交于 2019-12-19 10:27:41
问题 I am currently trying to read a txt file from a website. My script so far is: webFile = urllib.urlopen(currURL) This way, I can work with the file. However, when I try to store the file (in webFile ), I only get a link to the socket. Another solution I tried was to use read() webFile = urllib.urlopen(currURL).read() However this seems to remove the formating ( \n , \t etc) are removed. If I open the file like this: webFile = urllib.urlopen(currURL) I can read it line by line: for line in

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> 文件I/O fs模块的基本用法 开发中我们经常会有文件I/O的需求，node.js中提供一个名为fs的模块来支持I/O操作，fs模块的文件I/O是对标准POSIX函数的简单封装。 writeFile函数的基本用法 文件I/O，写入是必修课之一。fs模块提供writeFile函数，可以异步的将数据写入一个文件, 如果文件已经存在则会被替换。用法如下： 例： fs.writeFile(filename, data, callback) var fs= require("fs"); fs.writeFile('test.txt', 'Hello Node', function (err) { if (err) throw err; console.log('Saved successfully'); //文件被保存 }); appendFile函数的基本用法 writeFile函数虽然可以写入文件，但是如果文件已经存在，我们只是想添加一部分内容，它就不能满足我们的需求了，很幸运，fs模块中还有appendFile函数，它可以将新的内容追加到已有的文件中，如果文件不存在，则会创建一个新的文件。使用方法如下： 例： fs.appendFile(文件名,数据,编码,回调函数(err)); var fs= require(
