【最佳实践系列】AI程序员让我变成全栈：基于阿里云百炼DeepSeek的跨语言公告系统实战

 // 新增 genera 方法
        function genera() {
            var multiLineText = $("#multiLineText").val();
            if (!multiLineText) {
                $.modal.alertWarning("请输入关键词prompt。");
                return;
            }

            $.ajax({
                type: "POST",
                url: ctx + "system/notice/generateContent",
                data: { multiLineText: multiLineText },
                dataType: 'json',
                success: function(result) {
                    if (result.code == web_status.SUCCESS) {
                        console.log(result.data);
                        $('.summernote').summernote('code', result.data);
                    } else {
                        $.modal.alertError(result.msg);
                    }
                },
                error: function(error) {
                    $.modal.alertWarning("生成内容失败。");
                }
            });
        }
调用阿里云百炼大模型服务平台 的 DeepSeek-R1 的后端调用方法 system/notice/generateContent 的详细内容 
    @PostMapping("/generateContent")
    @ResponseBody
    public AjaxResult generateContent(String multiLineText) {
        String apiKey = "sk-f58bf46111222233355667777e18295d"; // 替换为实际的 Dashscope API Key
        String url = "https://dashscope.aliyuncs.com/compatible-mode/v1/chat/completions";

        // 构建请求体
        JSONObject requestBody = new JSONObject();
        requestBody.put("model", "deepseek-r1");
        JSONArray messages = new JSONArray();
        JSONObject message = new JSONObject();
        message.put("role", "user");
        message.put("content", multiLineText);
        messages.add(message);
        requestBody.put("messages", messages);

        // 发送 POST 请求并处理响应
        try {
            HttpURLConnection connection = (HttpURLConnection) new URL(url).openConnection();
            connection.setRequestMethod("POST");
            connection.setRequestProperty("Authorization",apiKey);
            connection.setRequestProperty("Content-Type", "application/json");
            connection.setDoOutput(true);
            try (OutputStream os = connection.getOutputStream()) {
                byte[] inputBytes = requestBody.toString().getBytes(StandardCharsets.UTF_8);
                os.write(inputBytes, 0, inputBytes.length);
            }

            // 获取响应
            int responseCode = connection.getResponseCode();
            if (responseCode == HttpURLConnection.HTTP_OK) {
                try (BufferedReader br = new BufferedReader(new InputStreamReader(connection.getInputStream(), StandardCharsets.UTF_8))) {
                    StringBuilder response = new StringBuilder();
                    String responseLine;
                    while ((responseLine = br.readLine()) != null) {
                        response.append(responseLine.trim());
                    }
                    JSONObject parse = (JSONObject) JSON.parse(response.toString());
                    JSONArray choices = parse.getJSONArray("choices");
                    StringBuilder sb = new StringBuilder();
                    for (Object choice : choices) {
                        JSONObject jsonObject = (JSONObject) choice;
                        JSONObject message1 = jsonObject.getJSONObject("message");
                        String content = message1.getString("reasoning_content");
                        sb.append(content);
                    }
                    System.out.println(sb.toString());
                    return AjaxResult.success("success",sb.toString());
                }
            } else {
                return AjaxResult.error("Error: " + responseCode);
            }
        } catch (Exception e) {
            e.printStackTrace();
            return AjaxResult.error("Exception: " + e.getMessage());
        }
    }
