摘要： The present disclosure discloses a method and an apparatus for detecting an access path. A specific implementation of the method includes: in response to receiving an access request for a source website, selecting a plurality of preset paths as candidate paths according to an address of the source website; transmitting the access request to the source website along each of the candidate paths in sequence until a successful transmission is detected; and in response to detecting the successful transmission, recording a successfully transmitting path as a default path for accessing the source website next time. This implementation implements dynamic adjustment of a website access path and maximizes a website access success ratio.
