Android：java.io.IOException：java.util.zip.DataFormatException：从服务器获取数据时距离太远

Question

我在一个运行良好的代码上遇到问题。 我正在运行异步任务以从 android 中的 Web 服务器获取数据，问题是当控件进入异步任务中的 readLine 时出现异常，详细信息如下：

BufferedReader reader = new BufferedReader(new
                        InputStreamReader(conn.getInputStream()));
                StringBuffer sb = new StringBuffer("");
                String line = "";

                while ((line = reader.readLine()) != null) {
                    sb.append(line);
                    break;
                }

堆栈跟踪：

我知道php中的数据没有损坏，我可以看到它正在正确返回对象。

    <?php
include 'includes/conn.php';
ini_set('display_errors', 1);
$u_id = $_GET['uid'];
$s = $_GET['s'];
$result = array();
$res = mysqli_query($con,"select u_id, first_name, last_name, user_profile_image from main_user_login where concat(first_name, ' ', last_name) like '%$s%'");

while ($row = mysqli_fetch_array($res)) {
    array_push($result,
    array('u_id'=>$row['u_id'],
    'first_name'=>$row['first_name'],
    'last_name'=>$row['last_name'],
    'user_profile_image'=>$row['user_profile_image']
    ));
}
echo json_encode(array("result"=>$result));
mysqli_close($con);

?>

这个问题突然出现，我知道这不可能是代码问题，因为没有完成代码更改并且这个问题开始出现。 请提出建议。

可能是数据解析不正确时抛出的错误。
