Configuring Proxy for Connecting to REST Web Service
When setting up a JSON or XML data source connection in Designer, if you use a proxy to connect to the REST Web Service in a restricted network, you can set the proxy parameters in a configuration file to enable the proxy to work successfully. This topic presents an example to show the proxy parameters you can define in the configuration file.
To configure the proxy parameters, you need to manually create the configuration file in XML and name it restdsproxy.xml in the <install_root>\bin folder. For example:
<?xml version="1.0" encoding="UTF-8"?>
<restdsproxy>
<proxymapping>
<urlpattern>https://.*\.jinfonet\.com/</urlpattern>
<proxyhost>192.0.0.14</proxyhost>
<proxyport>8888</proxyport>
<user>user1</user>
<password>psw1</password>
</proxymapping>
<proxymapping>
<urlpattern>http://.*\.jinfonet\.com\.cn/</urlpattern>
<proxyhost>192.0.0.14</proxyhost>
<proxyport>80</proxyport>
<user>user2</user>
<password>psw2</password>
</proxymapping>
</restdsproxy>The following shows the usage of each tag.
- restdsproxy
The root tag that contains one or more <proxymapping> subtags. - proxymapping
The whole set of the parameters of a proxy. It contains the following subtags, with each defining a specific proxy parameter. - urlpattern
A regular expression string supported by Java that matches the URL of a REST Web Service. If there are multiple URL patterns that match the same URL, the proxy setting in the <proxymapping> tag that contains the first one matched takes effect. - proxyhost
The host name or IP address of the proxy. - proxyport
The port number of the proxy. - user
The user name used for the proxy authentication. It is optional. - password
The password used for the proxy authentication. It is optional.
The <user> and <password> information is encrypted, and replaced by the <encrypt-sign> tag after Designer starts up.
<encrypt-sign>enDkq7srM9cHhoUwzYXJ3NvcDIYk</encrypt-sign>
If you want to change the user or password, delete the <encrypt-sign> tag and then add the <user> and <password> tags in restdsproxy.xml.
