Connect.js methodOverride有什么作用? [英] What does Connect.js methodOverride do?

问题描述

Connect.js 非常简洁的文档说methodOverride

The Connect.js very terse documentation says methodOverride

提供伪HTTP方法支持.

Provides faux HTTP method support.

那是什么意思?

What does that mean? The obvious Google search is less than helpful. Why is methodOverride useful?

推荐答案

• 如果要模拟DELETE和PUT，请使用methodOverride.
• 如果传入设置为'delete'或'put'的_method post参数，则可以在Express中使用app.delete和app.put代替一直使用app.post(因此更具描述性，冗长):
• If you want to simulate DELETE and PUT, methodOverride is for that.
• If you pass in the _method post parameter set to 'delete' or 'put', then you can use app.delete and app.put in Express instead of using app.post all the time (thus more descriptive, verbose):

后端:

// the app
app.put('/users/:id', function (req, res, next) {
  // edit your user here
});

客户端逻辑:

// client side must be..
<form> ...
  <input type="hidden" name="_method" value="put" />
</form>
