• 复现信息：如为报错，请给出复现环境、复现步骤 参考文档：Demo——部署一个在线lac分词服务步骤，最后客户端python调用报错，提示如下，我点开链接跟我粘的代码一样啊 `# coding: utf8 import requests import json

if name == "main": # 指定用于用于预测的文本并生成字典{"text": [text_1, text_2, ... ]} text_list = ["今天是个好日子", "天气预报说今天要下雨"] text = {"text": text_list} # 指定预测方法为lac并发送post请求 url = "http://127.0.0.1:8866/predict/text/lac" r = requests.post(url=url, data=text)

# 打印预测结果
print(json.dumps(r.json(), indent=4, ensure_ascii=False))`

提示如下 { "msg": "This usage is out of date, please use 'application/json' as content-type to post to /predict/lac. See 'https://github.com/PaddlePaddle/PaddleHub/blob/release/v1.6/docs/tutorial/serving.md' for more details.", "results": "", "status": "-1" }
