Servletresponse Download File garbled

With the help of powerful search engines and local experimentation.

In general, there are two ways to solve garbled characters:

1. Encode the file name (including Chinese characters) into UTF-8

String downloadorigalfile = "test file garbled. xlsx";

String downloadfilename = Java.net.URLEncoder.encode (Downloadorigalfile, "UTF-8");

Response.setheader ("Content-disposition", "attachment; Filename= "+ downloadfilename);

If a space appears in the file name, you need to replace the space with%20,utf-8 + to indicate a space

DownloadFileName = Downloadfilename.replace ("+", "%20");

2. Encode the file name into Iso-8859-1 (because the default encoding is iso-8859-1)

String downloadorigalfile = "test file garbled. xlsx";

Final String locale_encoding = "gb2312";

Here's locale_encoding=gb2312: You can usually use Java's system.getproperties () traversal to get

Generally there are two values may be related to this, please refer to the combination of actual use.

Sun.jnu.encoding=gbk

File.encoding=utf-8

Final String default_encoding = "Iso-8859-1";

String downloadfilename = new String (Downloadorigalfile.getbytes (locale_encoding), default_encoding);

If a space appears in the file name, you need to replace the space with%20

DownloadFileName = Downloadfilename.replace ("", "%20");

Here GetBytes () If you do not specify the encoding, there may be problems when cross-platform, it is recommended to explicitly specify the encoding.

Response.setheader ("Content-disposition", "attachment; Filename= "+ downloadfilename);

====

3, if you want to display Chinese in the browser address, you generally need to modify the default encoding of the Web container uriencoding= "UTF-8"

(i.e. download files directly using get)

For example, a Tomcat container that joins in the following location in the Tomcat_home/conf/server.xml

<connector port= "8080" protocol= "http/1.1" uriencoding= "UTF-8"

connectiontimeout= "20000"

redirectport= "8443"/>

4. Special codes commonly used in URLs

+ the + sign in the URL indicates a space%2b

Spaces in a space URL can be encoded with the + number or%20

/delimited directories and subdirectories%2f

? Separating the actual URLs and parameters%3f

% Specifies special characters%25

# indicates bookmark%23

& the delimiter between the parameters specified in the URL%26

= The value of the specified parameter in the URL%3d
