我为此做了一个除尘助手。我打电话给它{@query}
,这是它的签名:
{@query string="que=ry&str=ing"/}
que=ry&str=ing
它与实际参数合并req.query
,因此在我们之前的示例中http://localhost:3000/search?q=foo&sort=asc
:
<a rel="next" href="?{@query string="page=2"/}">Next</a>
将输出:
<a rel="next" href="?q=foo&sort=asc&page=2">Next</a>
--
实现如下(在可以访问的中间件中req.query
):
var dust = require('dustjs-linkedin');
var _ = require('underscore');
var qs = require('querystring');
app.use(function(req, res, next) {
//
// Query helper for dust
//
// Merge querystring parameters to the current req.query
//
// Suppose we are on localhost:3000/search?q=foo :
// - {@query string=""/} will output q=foo
// - {@query string="bar=baz"/} will output q=foo&bar=baz
// - {@query string="q=fooo&bar=baz"/} will output q=fooo&bar=baz (notice fooo takes precedence)
//
dust.helpers.query = function (chunk, ctx, bodies, params) {
var str = dust.helpers.tap(params.string, chunk, ctx);
// Parse string="" parameter
var o = qs.parse(str);
// Merge with req.query
o = _.extend({}, req.query, o);
return chunk.write(qs.stringify(o));
}
next();
});
