Accessing ArcGIS data over HTTP

Geographic Information Systems Asked by Darcy on December 26, 2020

I am attempting am building a map data React app using GIS data. I am accessing public GIS endpoints.

The endpoint is http://gis.infrastructure.gov.au/infrastructure/rest/services/KeyFreightRoute/KFR/MapServer/0

On local development, it is working fine. However, once pushed to live it returns the error: net::ERR_CONNECTION_REFUSED. Due to it being an HTTP endpoint.

The ArcGIS docs describe a solution using config, and I have included the following code:

    esriConfig.request.interceptors.push({
      // set the `urls` property to the URL of the FeatureLayer so that this
      // interceptor only applies to requests made to the FeatureLayer URL
      urls: featureLayerUrl,
      // use the BeforeInterceptorCallback to check if the query of the
      // FeatureLayer has a maxAllowableOffset property set.
      // if so, then set the maxAllowableOffset to 0
      before: function (params) {
        if (params.requestOptions.query.maxAllowableOffset) {
          params.requestOptions.query.maxAllowableOffset = 0;
        }
      },
      // use the AfterInterceptorCallback to check if `ssl` is set to 'true'
      // on the response to the request, if it's set to 'false', change
      // the value to 'true' before returning the response
      after: function (response) {
        if (!response.ssl) {
          console.log('not ssl');
          response.ssl = true;
        }
      },
    });

However, it still isn’t working!? In fact, the console.log(‘not ssl’) isn’t even logging on the live site (but it is logging on localhost).

How do you access HTTP GIS endpoints?

One Answer

Isn't this what you are looking for: http://gis.infrastructure.gov.au/infrastructure/rest/services/KeyFreightRoute/KFR/MapServer/0/query

Type "1=1" in the "Where" box and press "Query (POST)"
