[英]Configuring apache mod_proxy for cross-domain ajax calls
I started working on a small JavaScript app today that utilizes the Clipped API ( http://clipped.me/api.html ), but learned that there are cross-domain AJAX call issues, and the developer of the API didn't add support for JSONP. 我今天开始开发一个使用Clipped API( http://clipped.me/api.html )的小型JavaScript应用程序,但了解到存在跨域AJAX调用问题,并且该API的开发人员没有添加支持JSONP。 Here's the app itself:
这是应用程序本身:
var clippedAPI = "http://clipped.me/algorithm/clippedapi.php";
$.ajax({
url: clippedAPI,
type: "GET",
dataType: "JSONP",
data: {
url: "http://pandodaily.com/2013/03/26/y-combinator-demo-day-2013-still-looking-for- the-next-airbnb-or-dropbox/"}
}).done(function(json) {
console.log("JSON Data: " + json.title );
}).fail(function(jqxhr, textStatus, error){
var err = textStatus + ', ' + error;
console.log("Request Failed: " + err);
});
I've set up an Apache server on my Ubuntu machine, and have been suggested to use mod_proxy to set up a reverse proxy. 我已经在Ubuntu计算机上设置了Apache服务器,建议使用mod_proxy设置反向代理。 The problem is that I just don't know how to do this -- this is my first time using Apache.
问题是我只是不知道该怎么做-这是我第一次使用Apache。 I know all the basics like accessing my main Apache config files in Terminal.
我知道所有基本知识,例如在Terminal中访问我的主要Apache配置文件。 Can anyone give a noob a run-down on how to do this?
谁能给菜鸟一个简单的方法呢?
Setting up a reverse proxy using Apache in Ubuntu: 在Ubuntu中使用Apache设置反向代理:
1. Install reverse_proxy module 1.安装reverse_proxy模块
sudo apt-get install libapache2-mod-proxy-html
2. Install libxml if it is not already installed. 2.如果尚未安装libxml,请安装它。
apt-get install libxml2-dev
3. Load the modules in apache2.conf file 3.将模块加载到apache2.conf文件中
LoadModule proxy_module /usr/lib/apache2/modules/mod_proxy.so
LoadModule proxy_http_module /usr/lib/apache2/modules/mod_proxy_http.so
LoadModule headers_module /usr/lib/apache2/modules/mod_headers.so
LoadModule deflate_module /usr/lib/apache2/modules/mod_deflate.so
LoadFile /usr/lib/libxml2.so
4.Say you want to forward all requests starting to internal.server then add the following to your apache2.conf file 4,假设您要将所有请求转发到internal.server,然后将以下内容添加到apache2.conf文件中
# Disable proxy requests, using ProxyPass in vhost
ProxyRequests Off
# Block all requests
<Proxy *>
Order deny,allow
Deny from all
</Proxy>
<Proxy balancer://cluster>
BalancerMember http://internal.server:802
BalancerMember http://internal.server:801
#below is to transfer sessions
#ProxySet lbmethod=bytraffic
</Proxy>
<Location /balancer-manager>
SetHandler balancer-manager
Order Deny,Allow
# Deny from all
Allow from all
</Location>
5.Hopes you are good to go.! 5,希望你一切顺利!
update: 更新:
sudo aptitude download libxml2
sudo ar -xf libxml2_2.7.8.dfsg-5.1ubuntu4_amd64.deb
the following files will be extract from ubuntu package. 以下文件将从ubuntu软件包中提取。
control.tar.gz data.tar.gz debian-binary libxml2_2.7.8.dfsg-5.1ubuntu4_amd64.deb control.tar.gz data.tar.gz debian-binary libxml2_2.7.8.dfsg-5.1ubuntu4_amd64.deb
# rm libxml2_2.7.8.dfsg-5.1ubuntu4_amd64.deb control.tar.gz
# tar xf data.tar.gz
# cd usr/lib/x86_64-linux-gnu/
# ls
The following files will be there 以下文件将在那里
libxml2.so.2 libxml2.so.2.7.8 libxml2.so.2 libxml2.so.2.7.8
# mv * /usr/lib/x86_64-linux-gnu/
# cp /usr/lib/x86_64-linux-gnu/libxml2.so.2* /usr/lib/
# /etc/init.d/apache2 start
