php调用图片乱码问题
<meta charset="UTF-8"><?php //城市名 $city = '长沙'; //获取json格式的数据 $str = file_get_contents("http://api.map.baidu.com/telematics/v3/weather?location=".$city."&output=json&ak=KXrZyXh5wUSBEdo5TkgRQkBz"); //对json格式的字符串进行编码 $arr = json_decode($str,TRUE); echo "城市:".$arr['results'][0]['currentCity']." 日期:".$arr['date']."<br /><br />"; $wea = "http://1.alilo.sinaapp.com/Weather/0.jpeg"; $weai = imagecreatefromgif($wea); header("Content-type:image/jpeg"); imagejpeg($weai); foreach($arr['results'][0]['weather_data']as $val) { echo $val['date']."<br/>"; echo "天气:{$val['weather']}<br/>"; $path = "{$val['dayPictureUrl']}"; echo "$path"; $imgInfo = getimagesize($path); $imgType = $imgInfo[2]; switch ($imgType) { case 1: $img = imagecreatefromgif($path); header("Content-type:image/gif"); imagegif($img); break; case 2 : $img = imagecreatefromjpeg($path); header("Content-type:image/jpeg"); imagejpeg($img); break; case 3 : $img = imagecreatefrompng($path); header("Content-type:image/png"); imagepng($img); break; default: exit("图片格式不支持"); } echo "<br/>"; // echo "< img src = "{$val['dayPictureUrl']}" />"; echo "风向:{$val['wind']}<br/>"; echo "温度:{$val['temperature']}<br/><br />"; }?>
代码如上所示,输出来的是一串乱码。

回复讨论(解决方案)
你在一个页面中输出了两种类型的数据,浏览器不知道怎么把他们分开。于是就 乱码了
你需要将
$wea = "http://1.alilo.sinaapp.com/Weather/0.jpeg";
$weai = imagecreatefromgif($wea);
header("Content-type:image/jpeg");
imagejpeg($weai);
改为
echo '';
如果你确实想通过抓取图片的方式了完成,那么需要将那4行单独写成文件,比如 wea.php
然后通过标记
去调用

这一节功能是不要的,是我后面加上去测试用,主要是“foreach”后面的代码。按照你的改玩以后,foreach的代码还是显示乱码,求解。。
你不都是
$img = imagecreatefromgif($path);
header("Content-type:image/gif");
imagegif($img);
这样的吗?
一样的问题就不会举一反三吗?

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

Session hijacking can be achieved through the following steps: 1. Obtain the session ID, 2. Use the session ID, 3. Keep the session active. The methods to prevent session hijacking in PHP include: 1. Use the session_regenerate_id() function to regenerate the session ID, 2. Store session data through the database, 3. Ensure that all session data is transmitted through HTTPS.

The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.
