Question

我正在使用节点js中的web服务，它以这种奇怪的格式返回响应。我必须通过传递键名来提取某些值，并且我想将响应转换为JSON以便于解析。我应该怎么做呢？

这是我从网络服务

获得的

Data Source=*******;Initial Catalog=****;User ID=*******;Password=
*******;MultipleActiveResultSets=True;Min Pool Size=5;Max Pool Size=5000;Conn
ect Timeout=180;Application Name=*****

我想提取DataSource，UserID，密码。

Answer 1

达里奥的回答基本上就是诀窍，但是值得知道Node的querystring模块可以做这种事情并且＃34;免费＆＃34;。< / p>

代码

const qs = require('querystring');
const s = `Data Source=*******;Initial Catalog=****;User ID=*******;Password=*******;MultipleActiveResultSets=True;Min Pool Size=5;Max Pool Size=5000;Connect Timeout=180;Application Name=*****`;
console.log(qs.parse(s, ';', '='));

输出：

{ 'Data Source': '*******',
  'Initial Catalog': '****',
  'User ID': '*******',
  Password: '*******',
  MultipleActiveResultSets: 'True',
  'Min Pool Size': '5',
  'Max Pool Size': '5000',
  'Connect Timeout': '180',
  'Application Name': '*****' }

您可以使用String split轻松解析它：

您可以对其进行操作，删除或提取值，最后使用const obj = response.split(';', 2).reduce((json, pair) => { const tokens = pair.split('=', 2); json[tokens[0]] = tokens[1]; return json; }, {});在JSON中对其进行编码。

注意：正如Oleg V. Volkov评论的那样，如果源字符串包含键或值中的分隔符（';'和'='），则它将不起作用。

Answer 3

如果返回的模式是常量，则可以使用regexp实现：

var result = str.match(/Source=(.*);Initial.*ID=(.*);Password=(.*);Multiple/)

然后从匹配的组中获取所需的值。

DataSource = result[1];
UserId = result[2];
Password = result[3];

在节点js中将字符串转换为JSON？
