The embodiment of the invention discloses a method and device for obtaining a proxy of a web crawler. The method directs at a valid proxy in a first queue to obtain a valid proxy through second detection. After receiving return information of the webpage to be crawled by the web crawler through the valid proxy, evaluation parameters of the valid proxy are updated according to the return information. The 'high quality' proxy is added to a second queue through the evaluation parameters. Since the 'high quality' proxy is added to the first queue from the second queue at the interval of first preset time period, the situation that the valid proxy is banned because the web crawler frequently fetches the valid proxy from the first queue is avoided. The method realizes the level distinguishing ofthe proxy according to 'quality' through the second queue, and the valid proxy is added to the first queue from the second queue at the interval of first preset time period so as to avoid the frequent use of the 'high quality' proxy, supplement the number of the proxy in the first queue and improve the efficiency of information collection of the web crawler.
