Android：Volley HTTP 请求自定义标头

Question

我在运行应用程序时收到以下错误： BasicNetwork.performRequest：意外响应代码 401

我需要传递电子邮件、密码和令牌才能访问该 URL，但它不起作用

我上周开始学习android，我不太了解

Answer 1

JsonObjectRequest 是扩展 JsonRequest 直接覆盖 getBody() 方法，所以你的 getParam() 永远不会调用，我建议你扩展 StringRequest 而不是 JsonObjectRequest。

您可以查看this 答案了解更多详情。

顺便说一句，您还有另一个选择：Netroid，它基于 Volley，提供了更多功能。

Answer 2

如果您想将 Map 作为 Json 对象发送（您正在使用 JsonObjectRequest 类），则应将其放入 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), ..., ...);

见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);
