有毛demo，根据接口发送post请求， 可以先用postman 先手工研究一下，就几行代码的问题

BufferedImage img = ImageIO.read(file.getInputStream()); //获取图片的长和宽 int width = img.getWidth(); int height = img.getHeight(); // 调用微信上传图片接口 // 使用Hutool的HttpUtil上传图片 JSONObject jsonParam = new JSONObject(); jsonParam.put("upload_type",0); jsonParam.put("resp_type",0); jsonParam.put("height",height); jsonParam.put("width",width); List<String> list = new ArrayList<>(); for(String key : jsonParam.keySet()){ list.add(String.format("%s=%s",key,jsonParam.getString(key))); } String token = TenantTokenCacheUtils.getToken(UserContextHolder.getTenantId()); String strUrl = String.format("https://api.weixin.qq.com/channels/ec/basics/img/upload?access_token=%s&%s",token,String.join("&",list)); File tempFile = new File("D:\\temp_image.jpg"); file.transferTo(tempFile); HttpResponse response = HttpUtil.createPost(strUrl) .header("content-type", "image/jpg") .form("media", tempFile).execute();
