html - NodeJS : How to use html form to send PATCH & DELETE request

Question

我有一个 API，如果我需要更新对象，我应该发送 PATCH 请求；问题是，当我发送 PATCH 请求时，主体始终是未定义的。

这就是我发送 PATCH 请求的方式。

app.patch('/applications/update/:application_id', function(request, response) {
    var application_id = request.params.application_id;

    require('../../models/applications/update_application_by_id')
        .get(request.body, application_id, function(result) {
            response.render('applications/details', {
                application_details:result
            });
        });
});

<form enctype="application/json" class="form-horizontal" role="form" method="post" action="/applications/update/{{application_details._id}}">
    <input type="hidden" name="_method" value="PATCH" /> 
    <input type="text" name="name" class="form-control">

    <button type="submit" class="btn btn-yellow pull-right">update</button>
</form>

这就是我的处理方式

exports.get = function(request_body, application_id, call_back){
    var http_request = unirest("patch", "https://xx/api/applications/"+application_id);

    http_request.headers({
        "cache-control": "no-cache",
        "content-type": "application/json",
        "x-application-key": "xxxxxxxxxxxxxxxxxx"
    });

    http_request.type("json");
    http_request.send(request_body);

    http_request.end(function (http_response) {
        console.log(http_request.body);
        if (http_response.error) throw new Error(http_response.error);

        return call_back(http_response.body);
    });
}

您最好安装并 app.use()ing 中间件 express/methodoverride:

相当标准的方法，但请注意它所期望的实际字段名称。
