如何在python3.4+中解码JavaScript响应？

Question

我从一个网站上得到这个回复。我真的不知道如何解码，得到我想要的信息。你知道吗

下面是JavaScript响应：

{header:{code:0,message:{title:"",detail:""}},body:{parameters:{},dataStores:{"kccjStore":{pageSize:100,pageNumber:1,recordCount:3,name:"kccjStore",rowSetName:"pojo_com.neusoft.education.sysu.xscj.xscjcx.model.KccjModel",order:"kclb asc",metaData:{"jxbmc":{dataType:12},"njzypm":{dataType:12},"xh":{dataType:12},"jxbh":{dataType:12},"sftg":{dataType:12},"zzcj":{dataType:12},"cjzt":{dataType:12},"bzw":{dataType:12},"class":{dataType:12},"xs":{dataType:12},"xq":{dataType:12},"jsxm":{dataType:12},"xnd":{dataType:12},"resource_id":{dataType:12},"jxbpm":{dataType:12},"jd":{dataType:12},"kch":{dataType:12},"kcywmc":{dataType:12},"kcmc":{dataType:12},"khfs":{dataType:12},"cjlcId":{dataType:12},"xf":{dataType:12},"kclb":{dataType:12},"zpcj":{dataType:12}},rowSet:{primary:[{"jxbpm":"79\/93","bzw":"00","cjzt":"2","cjlcId":"11895237815","kcywmc":"Mobile Information Engineering Training:Intermediate ","jxbh":"46000092161002","zpcj":"90","resource_id":"11895237815","xnd":"2016-2017","xq":"1","kch":"46000092","kcmc":"移动信息工程实训（中级）","kclb":"11","xf":"3.0","xs":"72.0","zzcj":"90","jd":"4.0","sftg":"1","xh":"14353379","njzypm":"304\/403","class":"class com.neusoft.education.sysu.xscj.xscjcx.model.KccjModel"},{"jxbpm":"74\/128","bzw":"00","cjzt":"2","cjlcId":"12825792491","kcywmc":"Database Systems Lab","jxbh":"46000085161003","jsxm":"桑应朋","khfs":"03","zpcj":"94","resource_id":"12825792491","xnd":"2016-2017","xq":"1","kch":"46000085","kcmc":"数据库系统实验","kclb":"21","xf":"1.0","xs":"36.0","zzcj":"94","jd":"4.4","sftg":"1","xh":"14353379","njzypm":"157\/403","class":"class com.neusoft.education.sysu.xscj.xscjcx.model.KccjModel"},{"jxbpm":"20\/167","bzw":"00","cjzt":"2","cjlcId":"12825622928","kcywmc":"Database Systems","jxbh":"46000084161001","jsxm":"桑应朋","khfs":"01","zpcj":"87","resource_id":"12825622928","xnd":"2016-2017","xq":"1","kch":"46000084","kcmc":"数据库系统","kclb":"21","xf":"2.0","xs":"36.0","zzcj":"87","jd":"3.7","sftg":"1","xh":"14353379","njzypm":"34\/403","class":"class com.neusoft.education.sysu.xscj.xscjcx.model.KccjModel"}]}}}}}

我正在使用python3.4。下面是我的代码

html_doc = opener.open('http://wjw.sysu.edu.cn/api/score?year=2016-2017&term=1&pylb=01').read().decode('utf-8')

提前谢谢！你知道吗

-----------------

我以前误以为是JSON文件，问了个不好的问题。对此我很抱歉。但是谢谢你帮助我！希望你们中的一些人能在我的新问题上帮助我！你知道吗

Answer 1

您的输入有几个问题：

1. 你输入的括号不平衡。你缺少左大括号，{。你知道吗
2. JSON要求使用双引号引用所有键。您的输入使用不同的语法，这是有效的Javascript，但不是有效的JSON。如果必须的话，您可以使用第三方包（如^{}）将这些对象解析到python字典中。你知道吗

>>> import demjson
>>> parsed = demjson.decode('{header:{code:0,message:{title:"",detail:""}}}')
>>> parsed
{u'header': {u'message': {u'detail': '', u'title': ''}, u'code': 0}}

也就是说，你最初使用json.loads的本能大体上是正确的。如果您对输入有任何控制权（例如，如果您可以重写的是API或脚本的输出），您应该将其重写为输出严格的JSON，使其可由json.loads解析。你知道吗

Answer 2

如果您不想使用第三方库，您可以使用regex自己清理数据（例如，为其余属性添加双引号）：

import re
import json

text = # the input string

p = re.compile(r'({|,)([^{}:"]+):')
text = p.sub(r'\1"\2":', '{' + text)
obj = json.loads(text)

Answer 3

看起来您的数据不是严格意义上的JSON，因为有些键不是字符串。你知道吗

而且，似乎缺少一个匹配的大括号--应该作为第一个字符添加

{header:{code:0,message:{title:"",detail:""}},body:{parameters:{},dataStores:{"kccjStore":{pageSize:100,pageNumber:1,recordCount:3,name:"kccjStore",rowSetName:"pojo_com.neusoft.education.sysu.xscj.xscjcx.model.KccjModel",order:"kclb asc",metaData:{"jxbmc":{dataType:12},"njzypm":{dataType:12},"xh":{dataType:12},"jxbh":{dataType:12},"sftg":{dataType:12},"zzcj":{dataType:12},"cjzt":{dataType:12},"bzw":{dataType:12},"class":{dataType:12},"xs":{dataType:12},"xq":{dataType:12},"jsxm":{dataType:12},"xnd":{dataType:12},"resource_id":{dataType:12},"jxbpm":{dataType:12},"jd":{dataType:12},"kch":{dataType:12},"kcywmc":{dataType:12},"kcmc":{dataType:12},"khfs":{dataType:12},"cjlcId":{dataType:12},"xf":{dataType:12},"kclb":{dataType:12},"zpcj":{dataType:12}},rowSet:{primary:[{"jxbpm":"79\/93","bzw":"00","cjzt":"2","cjlcId":"11895237815","kcywmc":"Mobile Information Engineering Training:Intermediate ","jxbh":"46000092161002","zpcj":"90","resource_id":"11895237815","xnd":"2016-2017","xq":"1","kch":"46000092","kcmc":"移动信息工程实训（中级）","kclb":"11","xf":"3.0","xs":"72.0","zzcj":"90","jd":"4.0","sftg":"1","xh":"14353379","njzypm":"304\/403","class":"class com.neusoft.education.sysu.xscj.xscjcx.model.KccjModel"},{"jxbpm":"74\/128","bzw":"00","cjzt":"2","cjlcId":"12825792491","kcywmc":"Database Systems Lab","jxbh":"46000085161003","jsxm":"桑应朋","khfs":"03","zpcj":"94","resource_id":"12825792491","xnd":"2016-2017","xq":"1","kch":"46000085","kcmc":"数据库系统实验","kclb":"21","xf":"1.0","xs":"36.0","zzcj":"94","jd":"4.4","sftg":"1","xh":"14353379","njzypm":"157\/403","class":"class com.neusoft.education.sysu.xscj.xscjcx.model.KccjModel"},{"jxbpm":"20\/167","bzw":"00","cjzt":"2","cjlcId":"12825622928","kcywmc":"Database Systems","jxbh":"46000084161001","jsxm":"桑应朋","khfs":"01","zpcj":"87","resource_id":"12825622928","xnd":"2016-2017","xq":"1","kch":"46000084","kcmc":"数据库系统","kclb":"21","xf":"2.0","xs":"36.0","zzcj":"87","jd":"3.7","sftg":"1","xh":"14353379","njzypm":"34\/403","class":"class com.neusoft.education.sysu.xscj.xscjcx.model.KccjModel"}]}}}}}

Here是指向w3json引用的链接。你知道吗

Here是一个JSON格式化程序/验证程序。你知道吗
