python 处理 {'message': 'JSON parse error - Expecting value: line 1 column 1 (char 0)', 'code': 'parse_error'}

今天在运行自动化的过程中，遇到了 {'message': 'JSON parse error - Expecting value: line 1 column 1 (char 0)', 'code': 'parse_error'}这个的error，各种尝试无果：

请求的数据为json格式：

data = {'code_type': 'send', 'category': 1, 'phone': '13123456784'}

发送请求：requests.post(url,data)

返回结果：{'message': 'JSON parse error - Expecting value: line 1 column 1 (char 0)', 'code': 'parse_error'}

 

之前遇到过，尝试把json格式的数据转换为string，就解决了，今天怎么处理都不行，没法了，向万能的度娘求助，终于解决：

　　借助第三方包的帮助，这里使用了demjson的包来处理这个问题

     安装： pip install demjson

     使用： demjson.encode(data)

 demjson有两个主要的方法：

•   encode  编码，将对象转换为json
•   decode   解码，将json转化为对象

python单元测试
