This answer doesn't quite cover it since it appears that you have to pass a reconstructed URL into pathname If I am on the child page of these routes: <Route name="Parent" path="/parent/:parentId" component={Parent}> <Route name="Child" path="/child/:childId" component={Child}> how do I programmatically update the :parentId without having to re-construct the entire URL? Something along the lines of history.push({ ...., params: {parentId: 'newParent'}}) would be ideal.

The torrent info_hash parameter

阅读更多关于 The torrent info_hash parameter

问题 How does one calculate the info_hash parameter ? Aka the hash corresponding to the info dictionar??

This value will almost certainly have to be escaped. Does this mean simply get the substring from the meta-info file and do a sha-1 hash on the reprezentative bytes?? .... because this is how i tried 12 times but without succes

Getting more search results per page via URL

阅读更多关于 Getting more search results per page via URL

问题 I've been writing a program which extracts data from web searches. To get more data, I'd ideally like to extract more results per query through a script (let's say 100 or so). My question is, is there a way to modify the URL for Google, Yahoo, or Bing (preference in that order) so that I can get more than 10 results per query? For Google, appending &num=99 used to work at one point but no longer works :( I saw a similar append of &count=50 but that didn't work on any of the search engines

阅读更多关于 jquery mobile url parameter not updating in browser, but getting correct one with “data-url”

I created the following example to show what I am experiencing. If I navigate from page1 to page 2 with the button Page 2a, the URL will be ...#page2?id=a as expected. When I click the button to go back to Page 1, then navigate to Page 2b, the URL will still show "#page2?id= a ", but the <a> tag is clearly has an href of "#page2?id= b " along with the $(e.target).attr("data-url") being "#page2?id= b " when I get to #page2. Any ideas what is going on here? Thanks in advance for any help. <html> <head> <link rel="stylesheet" href="http://code.jquery.com/mobile/1.1.0/jquery.mobile-1.1.0.min.css"

Is it secure to put the user id as a url parameter?

阅读更多关于 Is it secure to put the user id as a url parameter?

I am developing a social network and I would like to know if in the profile page of a user I could put the user id stored in database as a parameter in the url or is it a bad idea in terms of security? I want the url to be bookmarkable. Should I put another thing instead of the user id? Darin Dimitrov In terms of security there's no problem in putting the user id in a url. For example StackOverflow does it already: https://stackoverflow.com/users/3477044/aliuk What's important is to verify that the currently authenticated user is allowed to access this url and take actions on its behalf. most
