How secure is a HTTP GET when the data is URL Encoded?

由 ╄→尐↘猪︶ㄣ 提交于 2019-12-19 03:22:05
问题 If the data is Url Encoded, is it secure enough to send login credentials over HTTP GET? 回答1: Not at all. URL encoded is easily reversible. You should encrypt the transport layer (i.e. use HTTPS) 回答2: No - URL encoding is meant to make sure all the characters you try to send with a GET request can actually arrive at the other end. It is actually designed to be easily encoded and decoded to prepare data for transport, not for security. 回答3: URL encoding is not any kind of encryption, it just

问题 I'm having an issue with a web app I'm building. The web app consists of an angular 4 frontend and a dotnet core RESTful api backend. One of the requirements is that requests to the backend need to be authenticated using SSL mutual authentication; i.e., client certificates. Currently I'm hosting both the frontend and the backend as Azure app services and they are on separate subdomains. The backend is set up to require client certificates by following this guide which I believe is the only

“No 'Access-Control-Allow-Origin' header is present on the requested resource.”

由 China☆狼群 提交于 2019-12-18 18:54:02
问题 I already tried looking for various questions, but that didn't help/I am too inexperienced to understand, so I have to be specific. This is what I get in the console: XMLHttpRequest cannot load https://a.websight.com/file/hex.json. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'chrome-extension://asdfghetcetcetc' is therefore not allowed access. (index):1 It's breaking my entire extension and I don't know how to fix it. I would appreciate any help. 回答1:

How to interpret grey items in Firebug Net panel?

由 我只是一个虾纸丫 提交于 2019-12-18 18:53:50
问题 I'm trying to debug some tricky behaviour in my web application: It appears as though an XHR GET request is being sent by the client, but the server never actually receives it. Furthermore, the client seems to receive duplicate data in the unseen request as the previous XHR request it sends. Further confounding matters, Firebug colors the second XHR request as light gray in the Net panel (the request here is third from the bottom, the second "GET test"): I haven't been able to find any

Executing Javascript written with XMLHttpRequest that contains script tags?

由 故事扮演 提交于 2019-12-18 18:04:27
问题 Through a Javascript request, XMLHttpRequest responds with some additional Javascript that needs to be added to the page the requesting page. Using eval(), if the response is something like: alert('This is the js response'); ... then this works just fine. However, the text returned could look something like this: <script language="javascript">var checkVar='checkVar: value 1';</script> but most likely: <script src="http://www.somesite.com/setCheckVarValue.js"></script> ... where additional JS
