Connect.js methodOverride有什么作用?

问题描述

Connect.js 非常简洁的文档说methodOverride

The Connect.js very terse documentation says methodOverride

那是什么意思? 远没有帮助.为什么methodOverride有用?

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>
