Answer 1

JsonObjectRequest 扩展JsonRequest，直接覆盖getBody()方法，因此 getParam（）永远不会调用，我建议你扩展< strong> StringRequest 而不是JsonObjectRequest。

您可以查看this答案了解详情。

顺便提一下，你有另一种选择：基于Volley的Netroid提供更多功能。

Answer 2

如果要将Map作为Json对象发送（使用类JsonObjectRequest），则应将其放在JsonobjectRequest构造函数中：

HashMap<String, String> params = new HashMap<String, String>();
params.put("email", "rm@test.com.br");
params.put("senha", "test");
params.put("X-API-TOKEN", "99KI9Gj68CgCf70deM22Ka64chef2C40Gm2lFJ2J0G9JkD0afd19MfacGf3FFm8CM1hG0eDiIk8");

JsonObjectRequest jsonObjReq = new JsonObjectRequest(url, new JSONObject(params), ..., ...);

请参阅this tuto

Answer 3

这个对我有用（见Volley JsonObjectRequest Post parameters no longer work）

String url = "https://www.youraddress.com/";

Map<String, String> params = new HashMap();
params.put("first_param", 1);
params.put("second_param", 2);

JSONObject parameters = new JSONObject(params);

JsonObjectRequest jsonRequest = new JsonObjectRequest(Request.Method.GET, url, parameters, new Response.Listener<JSONObject>() {
    @Override
    public void onResponse(JSONObject response) {
        //TODO: handle success
    }
}, new Response.ErrorListener() {
    @Override
    public void onErrorResponse(VolleyError error) {
        error.printStackTrace();
        //TODO: handle failure
    }
});

Volley.newRequestQueue(this).add(jsonRequest);
