I am using python2.7.13+selenium
ps: A few days ago, I tried to write this code many times, but it failed when I clicked the step of writing a letter, I think my problem should be roughly these points:
1. The write button cannot be located directly, and its parent directory id is dynamic. I used xpath to locate this dynamic id at that time, so failure is inevitable, so we need to continue to look up to find the parent directory, that is, more The success rate of hierarchical xpath (it is recommended to use more xpath/css) will be higher, because the fewer the layers, the greater the possibility of repetition (for example, the class of the subject in the 126 letter is the same as the class of the search box, of course, also there are many)
2. The loading of the page is not complete, resulting in an error when the element is not found, so I need to use display and implicit waiting
3. At the same time, clear the cache in the browser in time, because too much garbage will cause the browser to run slowly or even crash
Well, there are a lot of words, just paste the code directly:
