通过Windows命令提示符成功发送的CURL Cookies通过Windows批处理文件失败

Question

If I send the below two commands within a Windows Command Prompt

Command 1:

curl -d userId="my.name" -d password="my.password" https://localhost:443/test/login -X POST -c "cookies.txt" -w "%{response_code}" -k

Command 2:

curl -F file1=@"C:\\test.zip" https://localhost:443/test/upload -b "cookies.txt" -w "%{response_code}" -k

The cookies are received in the second call.

If I put the same two commands in a Windows batch file, the cookies are not received in the second call. Why?

Update:

The problem seems to be related to the passing of the cookie in the second call within the batch file. CURL's verbose output for the second call in Command Prompt (2nd command only, outside batch file) is:

As soon as I remove -b "cookies.txt" the Rebuilt URL to: ÔÇôb/ output goes away.

Answer 1

The problem was related to the encoding of the batch file. Very embarrassing that I didn't check this before. I didn't realise the file wasn't ANSI encoded. There was a UTF-8 character that looked like a hyphen. After converting to ANSI encoding, the character showed itself.
