Axios calculating wrong Content-Length about axios

[justindhillon]

For anybody trying to look at this issue, content length is calculated in lib/adapters/http.js.

@angelalawrence123 , this is a pretty big diffrence between postman and axios. You should make sure that everything is good on your side:

1. Ensure that the content of the request body is identical between Postman and Axios. Even small differences in payload content, such as whitespace or encoding, can result in different byte lengths.

2. Check that both Postman and Axios are serializing the request body in the same format. For example, if you're sending JSON data, make sure that the serialization process is consistent and produces the same result in both environments.

3. Verify that the Content-Type header and any other relevant headers are identical between Postman and Axios.

4. Ensure that character encoding settings are consistent between Postman and Axios. Encoding differences can lead to variations in byte length, especially for non-ASCII characters.

If you have snippets of your code, I will have an easier time diagnosing your problem.
