In fact, the work has more than three months, but the basic work just tinkering, did not do any major improvements, but the bug has a lot of experience. For the development of less experienced people, it really is a tune all day, experience and patience consumption. I can not say that is a summary of the experience, when I was recording it for future summary of it.
1. The image does not load it. Pictures pic_url find data by f12 page, I found to be null. Source pic_url extracted from certain xml file, write the correct node, other nodes are normal value. After parsing local files, you can really resolve it. Check again, the pic_url passed to the front after a package, so heavy to find the problem. Is null Since pic_url, the whole process is in retrospective pic_url source.
2. mimic sql stored procedure given, response.setHeader (msg, "ok") into no message. Most of the day to find a cause, compared to the correct sql process of discovery, inconsistent own sql file declare statements and other statements and order, there is no reason, only shows sql stored procedure is in order, it may be convenient to compile. The second occurs when too incredible, and finally through debugging found that in the final writing header to http packets, some order relations, did not actually write the header, do not understand the packaging method to http message, in fact, packaging method did not go according to the way we think. If the error is thinking that can not be found, because you do not know much about some of the underlying. Only to solve the problem by commissioning attempt.
3. Test report to me, made a name ending action, but the state of the state machine does not jump. grep view the log, you did see action sent a finish, id also symbols. But look at the log records, then go out immediately, as if did not do anything. View the associated actions by the swagger and the state, did not see the finish action, did not see finshed state. Ah, this error is very strange, like this impossible. If you are not aware of their bad habits you are being dragged into the abyss, then you really are stupid. Issue to the boss, the boss saw logs, check the swagger state. This is not a premature end? I rely on, it really is blind it? These steps I have seen, but there is no clear understanding. So the program is math, one a second, second, there is nothing equivocal, see key information.
4. The reaction test to compare two files, there is no difference in return, there is a difference between the actual file. Compare files before, first performed analytical work related files, which are automatically generated based on grammar, it seems right, then wrong Where? No idea, so I let the boss in the local resolution process to compare two files quickly and immediately locate the file parsing error. The principle is file some minor changes. When there is an error on the line test, this is very strange, it does not seem wrong. I do not know where the problem lies, blind to find. Boss said find the reasons, the file is garbled. Why is garbled? Download files are properly test, the original file stream has been compressed, but the code does not extract the files, it does not extract out. Experience: This error does not seem to guarantee a significant breakthrough, only the normal steps to install, step by step, can download files, download the file content, right, right parses the file and so on, one by one investigation of all aspects.
