500错误不是特定的错误，通常应指导您检查PHP日志文件以获取更多信息。确保已启用日志记录，并且在RequestQueue queue = Volley.newRequestQueue(getContext()); StringRequest postRequest = new StringRequest(Request.Method.POST, url1, new Response.Listener<String>() { @Override public void onResponse(String response) { Toast.makeText(mBaseAppCompatActivity, "Success", Toast.LENGTH_SHORT).show(); } }, new Response.ErrorListener() { @Override public void onErrorResponse(VolleyError error) { } } ) { @Override public Map<String, String> getHeaders() throws AuthFailureError { Map<String, String> params = new HashMap<String, String>(); String token = getToken(); params.put("Authorization", "Bearer " + token); params.put("Content-Type", "multipart/form-data"); return params; } @Override protected Map<String, String> getParams() { Map<String, String> params = new HashMap<String, String>(); params.put("terms", "true"); params.put("phone", "phoneNo"); return params; } }; queue.add(postRequest);文件中指定了文件。您可能要同时检查那里和您的网络服务器日志。

您的语法错误。您错过了一个冒号，而您的endforeach放在错误的位置。

尝试以下方法：

<!--- Carousel --> 
<div id="myCarousel" class="carousel slide" data-ride="carousel">
    <div class="carousel-inner">
        <?php foreach ($slider as $slider): ?>
        <div class="item-active">
            <img src="<?php echo base_url('upload/banner/'.$banner->image)?>">
            <div class="carousel-caption">
                <h3><?=$slider->name?></h3>
                <p><?=$slider->description?></p>
            </div>
        </div>
        <div class="item">
            <img src="<?php echo base_url('upload/banner/'.$banner->image)?>">
            <div class="carousel-caption">
                <h3><?=$slider->name?></h3>
                <p><?=$slider->dekripsi?></p>
            </div>
        </div>
        <?php endforeach; ?> 
    </div>
    <a class="left carousel-control" href="#myCarousel" data-slide="prev">
        <span class="glyphicon glyphicon-chevron-left"></span>
        <span class="sr-only"> previous</span>
    </a>
    <a class="right carousel-control" href="=#myCarousel" data-slide="next">
        <span class="glyphicon glyphicon-chevron-right"></span>
        <span class="sr-only"> next </span> 
    </a>
</div>

语法错误，意外的'endforeach'（T_ENDFOREACH），预期文件结尾（在我的滑块视图中-轮播）
