要获取标题,您需要覆盖 parseNetworkResponse()
in您的请求。
To get the headers you need to override parseNetworkResponse()
in your request.
例如 JsonObjectRequest
:
public class MetaRequest extends JsonObjectRequest {
public MetaRequest(int method, String url, JSONObject jsonRequest, Response.Listener
<JSONObject> listener, Response.ErrorListener errorListener) {
super(method, url, jsonRequest, listener, errorListener);
}
public MetaRequest(String url, JSONObject jsonRequest, Response.Listener<JSONObject>
listener, Response.ErrorListener errorListener) {
super(url, jsonRequest, listener, errorListener);
}
@Override
protected Response<JSONObject> parseNetworkResponse(NetworkResponse response) {
try {
String jsonString = new String(response.data,
HttpHeaderParser.parseCharset(response.headers, PROTOCOL_CHARSET));
JSONObject jsonResponse = new JSONObject(jsonString);
jsonResponse.put("headers", new JSONObject(response.headers));
return Response.success(jsonResponse,
HttpHeaderParser.parseCacheHeaders(response));
} catch (UnsupportedEncodingException e) {
return Response.error(new ParseError(e));
} catch (JSONException je) {
return Response.error(new ParseError(je));
}
}
}
