如何在Node.js中对内容进行URl编码？

Question

我想要对此进行URL编码：

SELECT name FROM user WHERE uid = me() 

我必须为此下载一个模块吗？我已经有了请求模块。

Answer 1

您可以使用JavaScript的encodeURIComponent

encodeURIComponent('select * from table where i()')

给予

'select%20*%20from%20table%20where%20i()'

Answer 2

内置模块querystring就是您要找的：

var querystring = require("querystring");
var result = querystring.stringify({query: "SELECT name FROM user WHERE uid = me()"});
console.log(result);
#prints 'query=SELECT%20name%20FROM%20user%20WHERE%20uid%20%3D%20me()'

Answer 3

使用querystring的escape函数。它生成一个URL安全字符串。

var escaped_str = require('querystring').escape('Photo on 30-11-12 at 8.09 AM #2.jpg');
console.log(escaped_str);
// prints 'Photo%20on%2030-11-12%20at%208.09%20AM%20%232.jpg'
