Backbone.js获取而不将数据作为URL字符串传递

Question

Suppose I want to fetch data for a Backbone.js model, while passing additional data:

myModel.fetch{ data: { bar: true } };

If you look at your request in Firebug, Backbone appended this data on to the URL:

GET http://www.example.net/foo?bar=true

This data appears under the 'parameters' tab in Firebug.

However, if I call a post or put using Backbone, the extra data being posted is not sent in the URL, but appears under a 'PUT' tab in Firebug.

PUT http://www.example.net/foo //additional data is not included in URL

On my server side (i'm using Node.js > Express), I pull the passed params (example 1) with request.query , but I pull the passed data (example 2) with request.body .

My question:

Is it best practice to throw get params in the URL? Should I have my server-side simply look for request.param for all GETs, or, is there a way to have Model.fetch() pass 'data' instead of 'params'?

Answer 1

GET Method

The GET operation, as defined in HTML, put the query string (or parameters) in the URL, and this is sent to the server. This is done because the GET should be used to retrieve data only. This data can be cached since you have the full parameters in the URL, this URL can be bookmarked and can stay in the browser history.

POST Method

A POST operation is intended to submit data to the server. No cache is done in this kind of operation. This is not stored in the browser history. Since you don't want to expose what you are sending the content goes in the body.

Saying this, the behaviour of the methods make sense and you should use this boths methods properly in your application and also take care of them in the server side independently.
