Volley BasicNetwork.performRequest：意外的响应代码 301

Question

Hello I am having a problem. I am using Volley to request to https://swapi.dev/

RequestQueue queue = Volley.newRequestQueue(this);
StringRequest request = new StringRequest(Request.Method.GET,
     "http://swapi.dev/api/planets/1/",
     System.out::println,
     null);
queue.add(request);

Then Volley throws an exception:

E/Volley: [53530] BasicNetwork.performRequest: Unexpected response code 301 for http://swapi.dev/api/planets/1/

Please help

You are using this url:

http://swapi.dev/api/planets/1/

Enable "ClearText" compatibility to allow connections using http: , this must be done inside your AndroidManifest.xml file:

   <application
        ...
        ....
        android:usesCleartextTraffic="true"
        ...
        ...

Is recommended to use only https:// like https://swapi.dev/api/planets/1/
