image

RequestQueue mVolleyQueue = Volley.newRequestQueue(this);
String url = "http://apis.baidu.com/apistore/weatherservice/weather?apikey=1e08b47bc5fc83bccc9b6bfb3b4cf1df&citypinyin=hangzhou";
JsonObjectRequest jsonObjectRequest = new JsonObjectRequest(Request.Method.GET, url, new Response.Listener<JSONObject>() {
@Override
public void onResponse(JSONObject response) {
Log.i("response>", response.toString());
}
}, new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
Log.i("error>", error.toString());
}
});
mVolleyQueue.add(jsonObjectRequest);

放到header

public class MyStringRequest extends StringRequest {
private Map<String, String> headers = new HashMap<String, String>();

    public MyStringRequest(int method, String url, Response.Listener<String> listener, Response.ErrorListener errorListener) {
        super(method, url, listener, errorListener);
    }

    @Override
    public Map<String, String> getHeaders() throws AuthFailureError {
        return headers;
    }

    public void setHeader(String title, String content) {
        headers.put(title, content);
    }
}

请求

RequestQueue mVolleyQueue = Volley.newRequestQueue(this);
String url = "http://apis.baidu.com/apistore/weatherservice/weather?citypinyin=hangzhou";
MyStringRequest myStringRequest = new MyStringRequest(Request.Method.GET, url, new Response.Listener<String>() {
@Override
public void onResponse(String response) {
Log.i("response>", response.toString());
}
}, new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
Log.i("error>", error.toString());
}
});
myStringRequest.headers.put("apikey", "1e08b47bc5fc83bccc9b6bfb3b4cf1df");
mVolleyQueue.add(myStringRequest);
