标签: nutzwk

代码如下，但是我在前端只收到 {} 

/**
	 * 图片文字识别
	 * @author smile
	 * @param test
	 * @return
	 */
	@POST
	@Ok("json")
	@At("/lexicalCheck")
	public Object lexicalCheck(@Param("test") String test) {
		try {
			
			JSONObject json_result = getJiuCuo(test);
			//这是json_result：  {"codeDesc":"Success","text_annotate":"睡觉吃饭","code":0,"conf":1,"text":"睡觉吃饭","message":""}
			return json_result;
		} catch (Exception e) {
			System.out.println("error..." + e.getMessage());
			return null;
		}
	}

return json_result.toString(); 如果这么返回， "{"codeDesc":"Success","text_annotate":"睡觉吃饭","code":0,"conf":1,"text":"睡觉吃饭","message":""}" 这样的结果，前端很难受

"{\"codeDesc\":\"Success\",\"text_annotate\":\"睡觉吃饭\",\"code\":0,\"conf\":1,\"text\":\"睡觉吃饭\",\"message\":\"\"}"

改成 @Ok("raw")

@Ok("raw:json") // 这样应该更好些

return json_result; 还是一样的 {}

return json_result.toString(); 就是如下返回

"{\"codeDesc\":\"Success\",\"text_annotate\":\"睡觉吃饭\",\"code\":0,\"conf\":1,\"text\":\"睡觉吃饭\",\"message\":\"\"}"

那就是getJiuCuo(test)里面完全写错咯

没道理啊 ，以下是getJiuCuo()方法返回，及日志

try {
			/* call 方法正式向指定的接口名发送请求，并把请求参数params传入，返回即是接口的请求结果。 */
			result = module.call("LexicalCheck", params);
			JSONObject json_result = new JSONObject(result);
			System.out.println("json_result"+json_result);
			return json_result;
		} catch (Exception e) {
			System.out.println("error..." + e.getMessage());
			return null;
		}

百度云纠错API返回值，转成JSONObject 对象，我想把这个对象直接返回到前端

result 是String吗?

是的

那就直接 return result 不要走JSONObject了

百度云返回值有unicode ,前端要单个转或者我要单个转换

{"code":0,"message":"","codeDesc":"Success","text":"\u7761\u89c9\u5403\u996d","text_annotate":"<em>\u7761\u89c9<\/em>\u5403\u996d","conf":2}

用nutz的Json.fromJson嘛

再说, 前端是认这种格式的,不需要转换

哇哦~~，下午试试

哇，return Json.fromJson(json_result); 只要这样就OK了，谢谢大佬

{
  "code": "0",
  "message": "",
  "codeDesc": "Success",
  "text": "睡觉吃饭",
  "text_annotate": "<em>睡觉</em>吃饭",
  "conf": "2"
}

嗯嗯
