Trying simple JS code to pull in a CSV ; works in sandbox, not outside

Question

Still a newbie here- trying simple JS code to pull in a CSV. It works in the sandbox but neither on my local server or pulled from a company web server. https:// developers.arcgis.com/javascript/jssamples/layers_csv.html I get: n {message: "Unable to load /proxy/?http://earthquake.usgs.gov/…quakes/feed/v1.0/summary/2.5_week.csv status: 404", response: Object, status: 404, responseText: "…was not found on this server.

The requested URL /proxy/ was not found on this server.

Hi Art,

The issue is you need to add a proxy in order to load csvfile that not coming from your local server domain. If you check this API document: CSVLayer | API Reference | ArcGIS API for JavaScript

It said that "If CSV files are not on the same domain as your website, a CORS enabled server or a proxy is required. "

Therefore you need to implement a proxy in your local server and in the code point to the proxy.ashx file.

For example, instead in the sandbox

esriConfig.defaults.io.proxyUrl = 'http://serverapi.arcgisonline.com/proxy/proxy.ashx'

You should point to your local server proxy url:

esriConfig.defaults.io.proxyUrl = 'http://yourlocaldomain.com/yourProxyFolderName/proxy.ashx'

You can download the Esri resource proxy from here: GitHub - Esri/resource-proxy: Proxy files for DotNet, Java and PHP.

For more detail about how to setup proxy, you can follow this Esri blog:

Setting up a Proxy | Support Services Blog

Hope this can help.
