节点服务器和python客户端文件上传

Question

有一个场景，我使用python客户机（请求库）和节点服务器（multer模块）。在

在Python方面-->

filepath = "./temp/test.step"
temp = {'file': ('test_file', open(filepath, 'rb'))}
r2 = requests.post('http://localhost:4041/upload', files = temp)
print("File Upload Status: " + r2.text)

在节点端-->

^{pr2}$

返回-->；错误：意外字段

提前谢谢你的建议。在

以下是我上传文件时遇到的错误：
