我正在构建能够搜索用户并获取信息的应用程序。情况是，当我在模拟器上运行它一切都很好但是当我在我的真实服务器上运行时，有时我得到用户详细，有时不。 我不知道为什么我会得到一些用户而不是其他用户。我检查并且不存在的用户我收到失败的消息但是对于存在的其他用户我收到消息。
例如： 正确的结果：

当它失败时我得到：
{"flag":"user not found"}
对于其他现有用户：
<html><head><meta http-equiv="refresh" content="0;http://biz.nf/errors/403.html" /></head><body></body></html>
我不知道为什么会这样：
我刚刚发现如果我脱掉那两行
$img_path = "images/".$row["image"];
$imgdata = base64_encode(file_get_contents($img_path));
and
"image" => $imgdata
结果很好。我的图像解码过程是否正确？因为在1个用户中我获得了图像但在其他用户中没有。

答案 0 :(得分：0)
现在一切正常。
