1.数据没有校验，系统处于裸奔状态，导致后期维护成本高； 2.编写一堆校验代码，混杂在业务代码中，导致代码可读性降低； 3.API交付的时候提供一大段接口描述文档，但用户还是要揣测文档意思。 4.自动校验json格式 5.自动纠正json错误格式 6.对于多层嵌套问题进行深入探讨 7.对于array拆分展开 8.特殊字符处理
- 使用transhex_chinese函数来转义汉语
- correstjson自动检测和自动校正json格式。
- 使用json.dump将校正后的dict数据转换为json格式
- 如果要展开嵌套json数据，首先需要使用json.load将json数据转换为dict数据，然后调用dict_generator函数
- The data is not checked and the system is running naked, which leads to the high cost of maintenance in the later stage.
- Write a bunch of check code, mixed with business code, resulting in less readability of the code; 3.API delivery provides a large number of interface description documents, but users still have to speculate on the meaning of the document.
- Automatic check json format
- Automatically correct json error format
- The problem of multi-layer nesting is discussed in detail.
- For array split expansion.
- Special character processing
- Use trans_hex_chinese function to escape Chinese
- Automatic Detection and automatic Correction of json format using demjson
- Using json.dumps to convert corrected dict data to json format
- If you want to expand nesting json data, you first need to use json.loads to convert json data to dict data, and then call the dict_generator function
- python -m cProfile no_corr_json.py

The specific explanations for each column output are as follows:：
●ncalls：Represents the number of function calls；
●tottime：Represents the total run time of the specified function, removing the running time of the child function called in the function；
●percall：(the first percall) is equal to tottime/ncalls；
●cumtime：Indicates the time when the function and all its subfunctions are called to run, that is, when the function starts calling to return.；
●percall：(the second percall) is the average time it takes a function to run once, equal to cumtime/ncalls；
●filename:lineno(function)：Specific information for each function call
Comparison between the three: profile is very slow and can only be used for some small script tests. Testing larger benchmark often takes more than ten minutes or more. Hotshot and cProfile are implemented in C. So itundefineds faster. Hotshot has a disadvantage that it doesnundefinedt support multithreaded programming, and itundefineds no longer maintained after python2.5, and the newer version no longer supports. CProfile is faster and more applicable than the other two.
- python -m cProfile -o no_corr_json.pstats no_corr_json.py
python gprof2dot.py -f pstats no_corr_json.pstats | dot -Tpng -o no_corr_json.png
