仅当使用直接链接访问时，才会显示在PHP中创建的映像

标签： php html json php-gd

我在localhost上创建了一个脚本，显示了json的一些统计信息。如果我访问直接链接，一切都很好。如果我尝试将该链接添加到HTML图像标记，则该页面将呈现为白色且没有图像。

可能是什么问题？如果您需要代码，我稍后会进行修改（我在移动设备上）。

此错误可能是由于使用localhost？

造成的 
<!DOCTYPE html>
<html>
<head>
    <title>TEST</title>
</head>
<body>
    <img src="localhost/banner.php?id=STEAMID&bg=bg1&rank=0"></a>
</body>
</html>

如果我访问localhost/file.php?id=NUMERIC_STEAMID，我可以看到该图片，但如果我添加此行<img src="" />，该页面仍为空。

？

本地主机/ banner.php ID = STEAMID＆安培; BG = BG1＆安培;秩= 0 应该是http://localhost/banner.php?id=STEAMID&bg=bg1&rank=0

答案 1 :(得分：0)

您的问题是您以错误的方式指向图像文件

<img src="localhost/banner.php?id=STEAMID&bg=bg1&rank=0"></a>

应该是这样的

<img src="http://localhost/banner.php?id=STEAMID&bg=bg1&rank=0"></a>

如果您不添加http://协议浏览器会将其读取为文件/目录，并会找到您的图像

假设您在localhost根目录

浏览器会将其加载为

http://localhost/localhost/banner.php?id=STEAMID&bg=bg1&rank=0

而不是

http://localhost/banner.php?id=STEAMID&bg=bg1&rank=0

当您直接访问您的图片时，您的浏览器会将其视为

http://localhost/banner.php?id=STEAMID&bg=bg1&rank=0
