# Build and install SRS.

2. Open the http_hooks feature to reproduce it.

Expect (Expected Behavior)

Please describe your expectation:

1. http_hooks should work properly.

I don't know why the value of SRS_HTTP_RESPONSE_OK is 'E'.

TRANS_BY_GPT3

[winlinvip]

Test:

#define SRS_HTTP_RESPONSE_OK    SRS_XSTR(ERROR_SUCCESS)
int main(int argc, char** argv, char** envp)
{
    printf("SRS_HTTP_RESPONSE_OK=%s\n", SRS_HTTP_RESPONSE_OK);
    return 0;
}

Return:

SRS_HTTP_RESPONSE_OK=ERROR_SUCCESS

It is because the mechanism is no longer correct after the error code has been changed.

Fixed in v5.0.88 07b3191
