Re: CORS configuration in ACS 7.0

Jump to solution

@waqar1  Like mentioned earlier, settings as per https://docs.alfresco.com/content-services/latest/config/repository/#cors-configuration or https://docs.alfresco.com/content-services/6.1/config/repository/#cross-origin-resource-sharing-cors... doesn't work and seems broken at repo layer. 

The settings are broken only with "*", valid urls works fine though. You may not be wanted to do this setting for prod as it is not recommended. Allowing only valid trusted remote origins as suggested. 

However, workaround given here does work for me.

This is what i did to test the workaround:

1- downloaded the two jar files:

https://repo1.maven.org/maven2/com/thetransactioncompany/cors-filter/2.5/cors-filter-2.5.jar

https://repo1.maven.org/maven2/com/thetransactioncompany/java-property-utils/1.9.1/java-property-uti...

2- Copied them to $TOMCAT_DIR/webapps/alfresco/WEB-INF/lib/ using DockerFile.

3- Taken the latest copy of web.xml from here: https://raw.githubusercontent.com/Alfresco/alfresco-community-repo/master/packaging/war/src/main/web...

 4- Updated it with CORS filters as suggested here: https://docs.alfresco.com/content-services/6.1/config/repository/#cross-origin-resource-sharing-cors... and kept the value for cors filter as

<init-param>
  <param-name>cors.allowOrigin</param-name>
   <param-value>*</param-value>
</init-param>

5- Copied the web.xml to $TOMCAT_DIR/webapps/alfresco/WEB-INF/web.xml via DockerFile, you can also use "sed" tool to update the web.xml file within the image without downloading a local copy as well. 

  <filter>
     <filter-name>CORS</filter-name>
     <filter-class>com.thetransactioncompany.cors.CORSFilter</filter-class>
     <init-param>

     </init-param>
     <init-param>
         <param-name>cors.supportedMethods</param-name>

         <param-name>cors.exposedHeaders</param-name>

     <init-param>
         <param-name>cors.supportsCredentials</param-name>
         <param-value>true</param-value>
     </init-param>
     <init-param>
          <param-name>cors.maxAge</param-name>
          <param-value>3600</param-value>
     </init-param>
   </filter>

COPY Dockerfile libs/*.jar $TOMCAT_DIR/webapps/alfresco/WEB-INF/lib/
#Copy updated web.xml COPY web.xml $TOMCAT_DIR/webapps/alfresco/WEB-INF/web.xml

6- Built the images and launched the containers. 

docker-compose up --build

To test used this simple code:

index.html

<!DOCTYPE html>
<html>

    <head>
        <meta charset="utf-8"/>
        <title>CORS Test</title>
        <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
        <script type='text/javascript' src="cors-test.js"></script>
    </head>
    <body onLoad='main();'>
    </body>
</html>
cors-test.js

function main() { console.log("main invoked..."); console.log("ajax request to the api that require cors enabled"); $.ajax ({ dataType: "xml", url: "http://localhost:7080/alfresco/s/api/login?u=admin&pw=admin", success: function(data) { console.log("log response on success"); console.log(data); } }); }

Re: CORS configuration in ACS 7.0

Jump to solution

It seems the cors config with "*" seems to break. Although documentation has mention of * to allow all origins :https://docs.alfresco.com/content-services/community/config/repository/#cors-configuration

but as per : https://alfresco.atlassian.net/browse/REPO-4219 it seems * is not even allowed, and should be left empty. 

Here are some workarounds though:

@waqar1  it is not necessary that alfresco is installed under /usr/local/tomcat directory only. When following the links relate the instructions as per your installation. 

As you are docker compose the path mentioned in link is correct that is: /usr/local/tomcat. I think you are looking for it on your host machine which is not correct. You have to check the container. 

If you are not aware on how to connect to a docker container, here are the steps:

1- Open command promot/power shell or terminal (whatever you are using) and type following command:

docker exec -it <nameOrIdOfContainer> /bin/bash

example:

docker exec -it alfresco_1 /bin/bash

or

docker exec -it 028 /bin/bash
Where name of the container is: alfresco
and container id: 0282bf706a57

If you are not sure how to get the container name of container id, then first execute the following commands before step 1 above, the below commad will display containers and their ids:

docker ps 

Output example:
https://hub.alfresco.com/t5/image/serverpage/image-id/1037i5D397466386337DB/image-size/large?v=v2&px=999

Based on output look for the container name or id (usually first 3 letters are enough to use).

3- Post connecting to container shell, follow the instructions you tried earlier. If it works then try to convert those steps into DockerFile and use it with docker-compose in combination because if you terminate the container the changes you made would be lost.

1- downloaded the two jar files:

https://repo1.maven.org/maven2/com/thetransactioncompany/cors-filter/2.5/cors-filter-2.5.jar

https://repo1.maven.org/maven2/com/thetransactioncompany/java-property-utils/1.9.1/java-property-uti...

2- Copied them to $TOMCAT_DIR/webapps/alfresco/WEB-INF/lib/ using DockerFile.

3- Taken the latest copy of web.xml from here: https://raw.githubusercontent.com/Alfresco/alfresco-community-repo/master/packaging/war/src/main/web...

 4- Updated it with CORS filters as suggested here: https://docs.alfresco.com/content-services/6.1/config/repository/#cross-origin-resource-sharing-cors... and kept the value for cors filter as

<init-param>
  <param-name>cors.allowOrigin</param-name>
   <param-value>*</param-value>
</init-param>

5- Copied the web.xml to $TOMCAT_DIR/webapps/alfresco/WEB-INF/web.xml via DockerFile, you can also use "sed" tool to update the web.xml file within the image without downloading a local copy as well.

         <param-value>origin, authorization, x-file-size, x-file-name, content-type, accept, x-file-type, range</param-value>
     </init-param>
     <init-param>
         <param-name>cors.exposedHeaders</param-name>
         <param-value>Accept-Ranges, Content-Encoding, Content-Length, Content-Range</param-value>
     </init-param>
     <init-param>
         <param-name>cors.supportsCredentials</param-name>
         <param-value>true</param-value>
     </init-param>
     <init-param>
          <param-name>cors.maxAge</param-name>
          <param-value>3600</param-value>
     </init-param>
   </filter>

6- Built the images and launched the containers. 

docker-compose up --build

To test used this simple code:

index.html

<!DOCTYPE html>
<html>

    <head>
        <meta charset="utf-8"/>
        <title>CORS Test</title>
        <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
        <script type='text/javascript' src="cors-test.js"></script>
    </head>
    <body onLoad='main();'>
    </body>
</html>
cors-test.js

function main() { console.log("main invoked..."); console.log("ajax request to the api that require cors enabled"); $.ajax ({ dataType: "xml", url: "http://localhost:7080/alfresco/s/api/login?u=admin&pw=admin", success: function(data) { console.log("log response on success"); console.log(data); } }); }
