我已经在这里面呆了很长时间了。我在服务器端进行了测试，它在postman中运行良好。任何帮助都会很好。问题是您正在从站点的端口3000上载到端口8000的端点。它们被认为是独立的来源，因此浏览器的安全功能正在发挥作用。您需要将它们放在同一个源上，或者将“Access Control Allow origin”头添加到上载终结点的服务器端响应。问题在于您正在从站点的端口3000上载到端口8000的终结点。它们被认为是独立的来源，因此浏览器的安全功能正在发挥作用。您需要将它们放在同一个源上，或者将“Access Control Allow origin”头添加到上载端点的服务器端响应中。请尝试这些方法
