I'm trying to use ARR to get layers from GeoServer to load on a web map hosted on IIS because I keep getting the "No 'Access-Control-Allow-Origin' header is present on the requested resource." error in my console.
I tried adding an ARR rule to the IIS website, but it doesn't change anything. I think that I might not understand well of this is supposed to work.
The rule is:
Requested URL: Matches the pattern
Pattern: geoserver.+
Rewrite URL: http://localhost:8080/{R:0}
Anyone can point what I'm doing wrong ?
Edit:
I followed this procedure: https://forums.iis.net/t/1189344.aspx but it doesn't work, I'm getting a Failed to load resource: net::ERR_CONNECTION_REFUSED error. My IIS server adress is http://localhost:1234/ and geoserver is http://localhost:8080. I wrote the localhost:1234 url in the GeoServer global setting, but I couldn't change the parameter in the web.xml as it doesn't seem to exist in my geoserver version (2.8) ...

I have uploaded WordPress manually on freewebhostingarea.com using my own domain. When I create a new page in Wordpress, I get some errors in javascript console (attached image1) but it lets me add/edit content. When I try to publish the page, I get the error 'Updating failed' and javascript console gives additional errors (attached image2) as below:
"Access to fetch at 'http://e.freewebhostingarea.com/not-found.html' (redirected from 'http://www.shia-match.com/wp-json/wp/v2/pages/16/autosaves?_locale=user') from origin 'http://www.shia-match.com' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled."
What could I be doing wrong?
Errors when creating a new WordPress page,
Errors when trying to publish page
Just had this same problem, the cross origin (CORS) policy blocking fetching by the https:// version of a site from the https://www version.
mediaguru’s answer alerted me to check the wp-config file. I found that I had added these lines, and so removed them:
define('WP_HOME', 'https://www.example.com');
define('WP_SITEURL', 'https://www.example.com');
I then rechecked WP’s Settings > General > WordPress Address (URL) and Site Address (URL). Prior to my edit of the wp-config file, they had displayed the www URL, but greyed out and non-editable. Now they had both reverted to the non www version of the URL (and were editable).
On my (Dreamhost) server, the canonical URL is set to www. So I changed the Settings > General URLs to www and… bingo. Solved.
It sounds like you just copied your wordpress files and db from one location to another? If so, you will need to change settings in your wordpress config as well as in your database to make sure the new location is not referring to the old location's database or files.
I'm trying to set up Apache Solr and run some experiments. I've set up the Solr search engine on my Ubuntu 18.04, indexed a few files, and it works perfectly given a specific query. The admin page is accessible on the default port on localhost:8983/solr
Now I was trying to setup a web-based client communicating with Solr. I found this simple project located at Google Code here. I extracted it, and follow the simple instructions to make the contents available via localhost http (using python -m http.server). So when I go to http://localhost:8000, I see the index.html client. Apparently the only thing we need to check for integration is js/solr-search.js file to make sure the solrURL is set correctly, which the default is good already:
var solrUrl = 'http://' + document.location.hostname + ':8983/solr/';
But when I try to press the search button, it doesn't show any results and the loading icon keeps showing:
Where is the problem? How can I fix the issue?
UPDATE: I debugged and noticed this error on index.html:
Failed to load http://localhost:8983/solr/admin/cores?wt=json: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:8000' is therefore not allowed access.
I have been searching for almost 2 hours to find a way to read a csv file that is hosted online. My data is hosted here.
I came across a library called papa parse. It apparently allows me to do that. I have the following code
Papa.parse("http://bahadorsaket.com/others/ranking.csv", {
download: true,
complete: function(results) {
console.log("Finished:", results.data);
}
})
It returns me following error: *
No 'Access-Control-Allow-Origin' header is present on the requested
resource. Origin 'null' is therefore not allowed access.
I was wondering if I am doing something wrong. OR there is a different way to load a csv file that is hosted online.
Thanks
There is chrome extension which can resolve this CORS error
Link :
https://chrome.google.com/webstore/detail/allow-control-allow-origi/nlfbmbojpeacfghkpbjhddihlkkiljbi?hl=en
Also you can start the chrome with below line which can also resolve it
chrome.exe --disable-web-security
This is for windows btw
Hope this helps
It is not that you are doing anything wrong, its that the remote URL doesnt allow cors and your browser will deny any traffic to remote origins. The safer option would be for you to make that call server side to get the csv and have papa.parse call a local endpoint.
I am trying to load info from the uber API using javascript on a web page.
Well, basically I am playing with this tutorial, but I am getting Access-Control-Allow-Origin errors.
I have my CLIENT ID and SERVER TOKEN, and I left most of the other options blanked.
I tried to host it in the localhost and filled http://localhost:8000 in the ORIGIN URI but with no luck.
For the page https://kylelam.github.io/final-section/, I tried filled in https://*, https://kylelam.github.io, and https://kylelam.github.io/*, with combination of with and without dataType: 'jsonp', but I am still having trouble figuring out what went wrong.
Try this in meantime as workaround CORS issue
http://crossorigin.me/
Unfortunately, port numbers for localhost will not correctly show up in the Access-Control-Allow-Origin header, even after setting the Origin URI field for your app. This is a known issue that we hope to fix soon.
I have two of the same site. My 1st site is http://educationaboveall.org/ and the 2nd is http://www.savantgenius.com .
1st site is loading properly on every device without any error but the 2nd (www.savantgenius.com) site is not loading properly in mobile and table devices. It is only loading properly in desktop browser. I have also found 32 console error.
Are there any jQuery issues? And please tell me how to be able to fix it.
I'm getting the "XMLHttpRequest cannot load
file:///D:/Work%20File/My%20Work%20File/mY%20Work%20Backup/Sophie/Work%20File/footer.html.
Cross origin requests are only supported for HTTP." and "Error: Failed
to execute 'send' on 'XMLHttpRequest': Failed to load
'file:///D:/Work%20File/My%20Work%20File/mY%20Work%20Backup/Sophie/Work%20File/footer.html"
error, but I don't know what's causing it nor how to fix it.
Please see the screenshot - http://prntscr.com/4fm0d8
I Think that you should call it from a http webserver and not like simple file in browser. This mean request a file in a web server like http://localhost/XML/catalog.html not from file:///E:/Projects/XML/catalog.html.
It is as the message says:
cannot load file:///D:/Work%20File/My%20Work%20File/mY%20Work%20Backup/Sophie/Work%20File/footer.html. .
You are referencing to a file on a Windows boxes filesystem and not in a webservers folder.
Second: you have a CORS-issue (which in this case is caused by the filesystem reference)
Cross origin requests are only supported for HTTP
See MDN for more infos.
To solve the issue, you have to configure your webserver to allow such requests. Check your webservers manual.
I had the same problem with my InfluxDB connection and it turns out I did not prepend the URL settings in the datasource with 'http://'. This could be nicer in Grafana, e.g. mentioning there is no protocol defined for accessing the source.
In your case it's clear that you somehow configured Grafana to look for D:\, which is not accessible for your browser. So check your data source URL.
