问题描述

限时删除!!

当编码查询字符串发送到Web服务器 - 什么是JavaScript才能使用的最佳做法:

使用转义:

 逃生(%+功放=);
 

使用EN codeURI()/ EN codeURIComponent()

 连接codeURI(http://www.google.com?var1=value1&var2=value2);

EN codeURIComponent(VAR1 =值1&放大器; VAR2 =值2);
 

解决方案

越狱()

不要使用它,因为它一直以来的ECMAScript V3 pcated德$ P $。

连接codeURI()

当你想要一个工作URL中使用EN codeURI。做这样的判断:

 连接codeURI(http://www.google.com/a文件spaces.html)
 

获得:

http://www.google.com/a%20file%20with%20spaces.html

不要叫EN codeURIComponent,因为它会破坏URL并返回

HTTP%3A%2F%2Fwww.google.com%2FA%20file%20with%20spaces.html

连接codeURIComponent()

当你想连接codeA的URL参数使用EN codeURIComponent。

 参数1 = EN codeURIComponent(http://xyz.com/?a=12&b=55)
 

然后,您可以创建你需要的网址:

  URL =htt​​p://domain.com/?param1=+参数1 +&放大器;参数2 = 99;
 

,你会得到这个完整的URL:

<$c$c>http://www.domain.com/?param1=http%3A%2F%2Fxyz.com%2F%Ffa%3D12%26b%3D55&param2=99

需要注意的是EN codeURIComponent没有逃脱字符。一个常见的​​错误就是用它来创建HTML属性,例如的href ='MyUrl',这可能遭受注入漏洞。如果您是从字符串构建HTML,要么使用,而不是为属性的行情,或加入编码额外的一层('可连接codeD为27%)。

有关此类型的编码,您可以检查的详细信息:http://en.wikipedia.org/wiki/Percent-encoding

When encoding a query string to be sent to a web server - what is the best practice to use from javascript:

Use escape:

escape("% +&=");

OR

use encodeURI() / encodeURIComponent()

encodeURI("http://www.google.com?var1=value1&var2=value2");

encodeURIComponent("var1=value1&var2=value2");
解决方案

escape()

Don't use it, as it has been deprecated since ECMAScript v3.

encodeURI()

Use encodeURI when you want a working URL. Make this call:

encodeURI("http://www.google.com/a file with spaces.html")

to get:

http://www.google.com/a%20file%20with%20spaces.html

Don't call encodeURIComponent since it would destroy the URL and return

http%3A%2F%2Fwww.google.com%2Fa%20file%20with%20spaces.html

encodeURIComponent()

Use encodeURIComponent when you want to encode a URL parameter.

param1 = encodeURIComponent("http://xyz.com/?a=12&b=55")

Then you may create the URL you need:

url = "http://domain.com/?param1=" + param1 + "&param2=99";

And you will get this complete URL:

http://www.domain.com/?param1=http%3A%2F%2Fxyz.com%2F%Ffa%3D12%26b%3D55&param2=99

Note that encodeURIComponent does not escape the ' character. A common bug is to use it to create html attributes such as href='MyUrl', which could suffer an injection bug. If you are constructing html from strings, either use " instead of ' for attribute quotes, or add an extra layer of encoding (' can be encoded as %27).

For more information on this type of encoding you can check: http://en.wikipedia.org/wiki/Percent-encoding
