在截击请求中添加自定义标头 [英] Add custom headers in volley request

问题描述

我有排球请求代码

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);

如何在此设置称为授权的标头?

How do I set a header called Authorization in this??

推荐答案

您可以编写一个扩展Request的类.(重写getHeaders()等等) 就像

you can write a class extends Request.(override getHeaders() and so on) just like

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);
    }
}
