问题描述
我有一个包含 2 个(或更多)嵌套对象的 json 对象,每个对象中有 18 个键值对,基本上 json 对象是一个存储文章的对象,每个嵌套对象都包含此类信息。
>{
createdAt: date,lastUpdated: date,content: of 250 words,...
.
.
.
.
.
.
and many more fields
}
现在我想将此对象发送到某个机器学习应用程序的 python 文件,并且我已经使用 spawn 模块完成了它,我通过以下命令发送此数据:
const childPython = spawn('python',['hello.py',JSON.stringify(posts)])
(node:21728) UnhandledPromiseRejectionWarning: Error: spawn ENAMetoOLONG

(Use `node --trace-warnings ...` to show where the warning was created)
(node:21728) UnhandledPromiseRejectionWarning: Unhandled promise rejection. This error originated either by throwing inside of an async function without a catch block,or by rejecting a promise which was not handled with .catch(). To terminate the node process on unhandled promise rejection,use the CLI flag `--unhandled-rejections=strict` (see https://nodejs.org/api/cli.html#cli_unhandled_rejections_mode). (rejection id: 1)
(node:21728) [DEP0018] DeprecationWarning: Unhandled promise rejections are deprecated. In the future,promise rejections that are not handled will terminate the Node.js process with a non-zero exit code.
现在我的问题是因为尺寸大,如果是的话,还有其他可能的解决方案来传达数据吗? 如果不是,我做错了什么,我该如何纠正?
