有一个错误被发回给你。那个错误就是错误 来自维基百科: 强调HTTP 404、404未找到和404错误消息是计算机网络通信中的超文本传输协议(HTTP)标准响应代码,用于指示客户端能够与给定服务器通信,但服务器无法找到请求的内容
尝试将请求从
/autocomplete/
更改为/autocomplete而不是flask用户,因此这可能不是问题所在,但您将请求发送到/autocomplete/
(尾随斜杠),同时将控制器映射到'/autocomplete'
(无尾随斜杠)。这些url不相同。请尝试在返回结果之前将结果[:10]转换为json,API无法返回您想要的任何内容。。。。导入jsonify,然后返回jsonify(result[:10])现在的问题将是代码中的一个bug。请查看原始问题的评论。
