What are the test steps of dynamic proxy IP?

Now? , We are using agents more and more ip, The number of agent service providers in the market is also increasing , So how do we test the effectiveness of the agent ？ Take a look at the introduction below .

1、 Number of tests .
During the evaluation , The sample should not be too small , If you only test more than ten times, you can't easily draw a conclusion , choice 500 Moderate evaluation quantity , That is to say, each packet is extracted 500 An agent to test .

2、 computing time .
Because we have a project to test the response speed of the agent , We need to calculate the time interval before the program requests and after getting the response , Here we use the test Python Kuo is requests, Therefore, we only need to calculate the time interval between initiating the request and obtaining the response .

3、 Beyond the time limit .
You will not encounter the problem of proxy request timeout during the test , Therefore, we also need to unify a timeout , Here it's set to 60 second , If you use a proxy to request Baidu , No response yet 60 second , The agent is considered invalid .

4、 Withdraw cash on a pro rata basis .
Besides , There is also a principle to be followed in the evaluation , That is, take and measure now , Take one and measure one . Suppose we extract... At one time 100 A broker , But this 100 Two agents do not participate in the test at the same time , The agency will go through a waiting period , If these agents are extracted after a period of time , Then the effectiveness of the latter agent will be affected .

5、 The test link .
We also need to use a stable server without anti crawler links when testing , This can eliminate the interference of the server , Here we take Baidu as the test target .
