我有排球要求代码
RequestQueue queue = Volley.newRequestQueue(this);
String url =<My URL>;
// Request a string response from the provided URL.
StringRequest stringRequest = new StringRequest(Request.Method.GET, url,
new Response.Listener<String>() {
@Override
public void onResponse(String response) {
// Display the first 500 characters of the response string.
mTextView.setText("Response is: "+ response.substring(0,500));
}
}, new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
mTextView.setText("That didn't work!");
}
});
// Add the request to the RequestQueue.
queue.add(stringRequest);
如何在其中设置称为授权的标头？
您可以编写一个类扩展Request。（重写getHeaders（）等等），就像
public abstract class AbsRequest<T> extends Request<T>{
public AbsRequest(int method, String url, Response.ErrorListener listener) {
this(method, url, null, listener);
}
public AbsRequest(int method, String url, Map<String, String> params, Response.ErrorListener listener) {
this(method, url, params, null, listener);
}
public AbsRequest(int method, String url, Map<String, String> params, Map<String, String> head, Response.ErrorListener listener) {
this(method, url, params, head, null, listener);
}
public AbsRequest(int method, String url, Map<String, String> params, Map<String, String> head, String bodyContentType, Response.ErrorListener listener) {
this(method, url, params, null, head, bodyContentType, listener);
}
public AbsRequest(int method, String url, String body, Map<String, String> head, String bodyContentType, Response.ErrorListener listener) {
this(method, url, null, body, head, bodyContentType, listener);
}
private AbsRequest(int method, String url, Map<String, String> params, String body, Map<String, String> head, String bodyContentType, Response.ErrorListener listener) {
super(method, url, listener);
}
}
