如何使用Volley发送表单数据(如Postman中的表单数据)？

dependencies {
    implementation 'com.android.volley:volley:1.2.0'
}

RequestQueue requestQueue = Volley.newRequestQueue(context.getApplicationContext());

String url = "https://example.com/submit";
StringRequest stringRequest = new StringRequest(Request.Method.POST, url,
        new Response.Listener<String>() {
            @Override
            public void onResponse(String response) {
                // 请求成功回调
            }
        }, new Response.ErrorListener() {
            @Override
            public void onErrorResponse(VolleyError error) {
                // 请求失败回调
            }
        }) {
    @Override
    protected Map<String, String> getParams() {
        Map<String, String> params = new HashMap<>();
        params.put("key1", "value1");
        params.put("key2", "value2");
        return params;
    }
};

requestQueue.add(stringRequest);
