在Express.js中使用PUT方法 [英] Using the PUT method with Express.js

问题描述

我正在尝试为Express.js应用程序实现更新功能，我想使用PUT请求发送新数据，但我一直在使用PUT收到错误。从我读过的所有内容来看，这只是使用app.put的问题，但这不起作用。我的路线文件中有以下内容：

I'm trying to implement update functionality to an Express.js app, and I'd like to use a PUT request to send the new data, but I keep getting errors using PUT. From everything I've read, it's just a matter of using app.put, but that isn't working. I've got the following in my routes file:

send = function(req, res) { 
    req.send(res.locals.content);
};

app.put('/api/:company', function(res,req) {
    res.send('this is an update');
}, send);

当我使用邮递员发出PUT请求时，我得到一个不能PUT / api / petshop作为一个错误。我不明白为什么我不能PUT，或者出了什么问题。

When I use postman to make a PUT request, I get a "cannot PUT /api/petshop" as an error. I don't understand why I can't PUT, or what's going wrong.

推荐答案

你可能缺乏实际的更新功能。当你告诉数据库更新数据时，你有put路径将结果返回给客户端但缺少部分。

You may be lacking the actual update function. You have the put path returning the result back to the client but missing the part when you tell the database to update the data.

如果你使用的是mongodb和express，你可以这样写：

If you're using mongodb and express, you could write something like:

app.put('/api/:company', function (req, res) {
    var company = req.company;

    company = _.extend(company, req.body);

    company.save(function(err) {
    if (err) {
        return res.send('/company', {
            errors: err.errors,
            company: company
        });
    } else {
        res.jsonp(company);
    }

});
