Hi @Jonnywang, if you disable a rule, what the value of console.log(res.data) and console.log(res.data.length) from your code?

Is it the same value (108)? 🤔

[NghiaTranUIT]

From the second screenshot, the value of console.log(res.data) is a binary (You can see the invalid characters).

The reason why you see the Base64 string in console.log(response.body) is because we convert the binary value to Base64 string since there is no way to pass Binary Data from Swift to the JavascriptCore. Therefore, the string might take 152 in lengths rather than 108 from the binary format.

Proxyman also converts the base64 string in the response.body to the binary format too.

So it's correct behavior 🤔

Not sure what this behavior causes to you @Jonnywang ?

152 is right, server response data is base64 encode data, but after using proxy the client got not collect response data length

@Jonnywang if you don't mind, please help me log two following scenario:

1. Disable a rule, what the value of console.log(res.data) and console.log(res.data.length) from your code?
2. Enable a Rule, what the value is?

It's easier for me to fix it 😄

after disable rule, client logs
