在使用postman时遇到的小问题，记录一下：
报错信息如下：
Could not get any response
There was an error connecting to https://xxxxxxxxxxxxx/uatservices/customer-api/user/verify/code/photo.
Why this might have happened:
-
The server couldn't send a response:
Ensure that the backend is working properly
-
Self-signed SSL certificates are being blocked:
Fix this by turning off 'SSL certificate verification' in Settings > General
-
Proxy configured incorrectly
Ensure that proxy is configured correctly in Settings > Proxy
-
Request timeout:
Change request timeout in Settings > General
我试了一下修改：
和
都没有能够成功；
后来我仔细检查，是Headers中的某个key多了个空格，把这个空格去掉后就正常了；
