发布JSON数据以呈现页面 [英] Post JSON data to render page
问题描述
我从URL:/ accounts /:id / users获得我的搜索结果为JSON格式,我需要检索该JSON数据以呈现/ contacts / find。 (后一页显示搜索结果。)
这是我的应用路由器。有了这个,我可以在JSON格式中看到/ contacts / find中的搜索结果:
app.post('/ contacts / find',function(req,res){
var searchStr = req.param('searchStr',null);
if(null == searchStr){
res.send(400 );
return;
}
models.Account.findByString(searchStr,function onSearchDone(err,accounts){
if(err || accounts.length = = 0){
res.send(404);
} else {
res.send(accounts);
}
});
} );
如何使用帐户(采用JSON格式)并使用帐户重新呈现网页信息?
app.get('/ contacts / find',函数(req,res){
res.render('searchResult.ejs',{
accounts:req.accounts,
email:req.accounts.email
})
}
app.get方法不起作用,URL只显示JSON数据。 / p>
accounts
是一个JSON字符串吗?在这种情况下,您可以解析它(将其转换回对象)并将结果传递给您的模板: req.accounts); res.render('searchResult.ejs',{
accounts:accounts,
email:accounts.email
})
I am getting my search result as JSON format from the URL: "/accounts/:id/users" and I need to retrieve that JSON data to render "/contacts/find". (The latter page shows search results.)
Here is my app router. With this I could see the result of the search in /contacts/find in JSON format:
app.post('/contacts/find', function(req, res) {
var searchStr = req.param('searchStr', null);
if ( null == searchStr ) {
res.send(400);
return;
}
models.Account.findByString(searchStr, function onSearchDone(err,accounts) {
if (err || accounts.length == 0) {
res.send(404);
} else {
res.send(accounts);
}
});
});
How can I use "accounts" (in JSON format) and re-render the page with the account info? I am trying with the below code snippet, but it does not work.
app.get('/contacts/find', function(req, res) {
res.render('searchResult.ejs', {
accounts: req.accounts,
email: req.accounts.email
})
}
The app.get method is not working. The URL just shows JSON data.
So accounts
is a JSON string? In that case, you can parse it (to convert it back to an object) and pass the result to your template:
var accounts = JSON.parse(req.accounts);
res.render('searchResult.ejs', {
accounts : accounts,
email : accounts.email
})
