<Response body is empty>

当一个HTTP请求被发送到服务器并且服务器成功处理了该请求，服务器将会返回一个HTTP响应。HTTP响应由响应头和响应体两部分组成。如果响应体为空，则表示服务器成功处理了请求，但没有返回任何数据。这种情况下，响应头中的Content-Length字段通常为0。因此，<Response body is empty>表示服务器成功处理了请求，但没有返回任何数据。

Hutool二维码 Springboot <Response body is empty>

Hutool是一个开源Java工具包，其中包含了一个方便易用的二维码生成模块。要在Spring Boot应用中使用Hutool生成二维码，并解决`Response body is empty`的问题，你需要做以下几步：

1. **添加依赖**：
将Hutool二维码相关的依赖添加到项目的pom.xml或build.gradle文件中：
Maven:

   <dependency>
       <groupId>cn.hutool</groupId>
       <artifactId>hutool-all</artifactId>
       <version>最新版本号</version>
   </dependency>

Gradle:

   implementation 'cn.hutool:hutool-all:最新版本号'

2. **生成二维码**：
使用Hutool提供的QRCode工具类来生成二维码图片：

   import cn.hutool.core.io.IoUtil;
   import cn.hutool.core.util.RandomUtil;
   import cn.hutool.crypto.RandomUtil;
   import cn.hutool.log.Logs;

   @Autowired
   private QrCode qrCode;

   public String generateQRCode(String content) {
       try {
           byte[] qrData = qrCode.encode(content, QrCode.ECCLevel.L);
           String imgBase64 = RandomUtil.randomAlphaNum(32) + ".png"; // 临时保存的图片名
           IoUtil.saveFile(qrData, "classpath:" + imgBase64);
           return imgBase64; // 返回Base64编码的图片路径
       } catch (Exception e) {
           Logs.error(e);
           throw new RuntimeException("Failed to generate QR code", e);
       }
   }

3. **返回响应体**：
在Controller中，调用`generateQRCode`方法并将结果转换为响应体发送回去，记得指定正确的Content-Type：

   @GetMapping("/generate-hutool-qr")
   public ResponseEntity<String> generateHutoolQR(@RequestParam(value = "content") String content) {
       try {
           String qrBase64 = generateQRCode(content);
           return ResponseEntity.ok()
                   .header(HttpHeaders.CONTENT_DISPOSITION, "attachment; filename=二维码.png")
                   .contentType(MediaType.IMAGE_PNG)
                   .body(qrBase64);
       } catch (Exception e) {
           return ResponseEntity.status(HttpStatus.BAD_REQUEST).body("生成二维码失败");
       }
   }

如果遇到`Response body is empty`错误，可能是返回的图片流没有被正确地处理。检查一下是否成功生成了二维码以及响应头设置是否正确。

这是一个 PHP 代码段，用于调用 OpenAI API 进行语音转写、文本嵌入和文本自动补全等操作。要将此代码段添加到 PHP 文件中，只需将其复制并粘贴到 <?php 和 ?> 标记之间即可。请确保在添加代码之前，您已经安装了 Meow AI 插件，并将其配置为使用 OpenAI API。
