Get a list of every Layer, in every Service, in every Folder in an ArcGIS REST endpoint

By -

I have two ArcGIS REST endpoints for which I am trying to get a list of every layer:

https://rdgdwe.sc.egov.usda.gov/arcgis/rest/services https://services1.arcgis.com/RLQu0rK7h4kbsBq5/ArcGIS/rest/services

These are not my organization's endpoints so I don't have access to them internally. At each of these endpoints there can be folders, services, and layers, or just services and layers.

My goal is to get a list of all layers. So far I have tried:

endpoints=(["https://rdgdwe.sc.egov.usda.gov/arcgis/rest/services",
"https://services1.arcgis.com/RLQu0rK7h4kbsBq5/ArcGIS/rest/services"])

for item in endpoints:
    reqs = requests.get(item, verify=False) 
    # used this verify because otherwise I get an SSL error for endpoints[0]
    soup =BeautifulSoup(reqs.text, 'html.parser')

    layers = []
    for link in soup.find_all('a'):
        print(link.get('href'))
        layers.append(link)

However this doesn't account for the variable nested folders/services/layers or services/layer schemas, and it doesn't seem to be fully appending to my layers list.

I'm thinking I could also go the JSON route and append ?f=psjon . So for example:

https://rdgdwe.sc.egov.usda.gov/arcgis/rest/services/?f=pjson would get me the folders https://rdgdwe.sc.egov.usda.gov/arcgis/rest/services/broadband/?f=pjson would get me all the services in the broadband folder and https://rdgdwe.sc.egov.usda.gov/arcgis/rest/services/broadband/CDC_5yr_OpioidOverDoseDeaths_2016/MapServer?f=pjson would get me the CDC_OverDoseDeathsbyCounty2016_5yr layer in the first service (CDC_5yr_OpioidOverDoseDeaths_2016) in the broadband folder.

Any help is appreciated. I put this here vs in the GIS stack exchange as it seems a more python question than geospatial.

Spring Elasticsearch Operations

By -
Elasticsearch Operations Spring Data Elasticsearch uses two interfaces to define the operations that can be called against an Elasticsearch index. These are ElasticsearchOperations and ReactiveElasticsearchOperations. Whereas the first is used with the classic synchronous implementations, the second one uses reactive infrastructure. The default implementations of the interfaces offer: Read/Write mapping support for domain types. A rich query and criteria api. Resource management and Exception translation. ElasticsearchTemplate The ElasticsearchTemplate is an implementation of the ElasticsearchOperations interface using the Transport Client. @Configuration public class TransportClientConfig extends ElasticsearchConfigurationSupport {   @Bean   public Client elasticsearchClient() throws UnknownHostException {                      Settings settings = Settings.builder().put("cluster.name", "elasticsearch")....

Hibernate Search - Elasticsearch with JSON manipulation

By -
Elasticsearch with JSON manipulation Elasticsearch ships with many features. It is possible that at some point, one feature you need will not be exposed by the Search DSL. To work around such limitations, Hibernate Search provides ways to: Transform the HTTP request sent to Elasticsearch for search queries. Read the raw JSON of the HTTP response received from Elasticsearch for search queries. Direct changes to the HTTP request may conflict with Hibernate Search features and be supported differently by different versions of Elasticsearch. Similarly, the content of the HTTP response may change depending on the version of Elasticsearch, depending on which Hibernate Search features are used, and even depending on how Hibernate Search features are implemented. Thus, features relying on direct access to HTTP requests or responses cannot be guaranteed to continue to work when upgrading Hibernate Search, even for micro upgrades (x.y.z to x.y.(z+1)). Use this at your own risk....
