Python3 value string interception

Interface return a json. json in turn contains a string, the string encoding and there, then how are we to intercept a variety of value you want it?

Gets a string from json returned interface in ways please refer here: https://www.cnblogs.com/Zhan-W/p/11876366.html

 Next on the record about how the results have been intercepted want to get out from a string of:

Objectives: args taken from this string value, but the value args comprising a plurality of values, while there are encoding

eg: https://www.xxxxxxx.com/new/#/register/h5?ProjectType=0&args=eyJ0ZW5hbnROYW1lIjoiV01TXzUyMF8zODk0Iiwic2hhcmVQYXJhbSI6Im4zNGdDLzR1RnpNTkY0RVl5eWhUY3U4SlNmQ3JCbTExZGpQeE9uQld0Z2wyQXFJQmdFSGpsUT09In0%3d

Steps are as follows:

1, the first decoding

# __*__coding:utf-8 __*__
import urllib.parse
import base64
import json

# The args string S is encoded in the 
S = " https://test.xxxxxx.com/new/#/register/h5?ProjectType=0&args=eyJ0ZW5hbnROYW1lIjoiV01TXzUyMF8zODk0Iiwic2hhcmVQYXJhbSI6Im4zNGdDLzR1RnpNTkY0RVl5eWhUY3U4SlNmQ3JCbTExZGpQeE9uQld0Z2wyQXFJQmdFSGpsUT09In0%3d " 
# to decode the string S 
= url_parameter_1 urllib.parse.unquote (S)
 Print ( " decoded url_parameter_1 values: " , url_parameter_1)

Decoded result is:

 

 

2, sliced

# To the decoded string S from the field "args =" slice by using a Split () 
url_parameter_2 = url_parameter_1.split ( " args = " )
 Print ( " sliced url_parameter_2 values: " , url_parameter_2)
 # viewing slices after url_parameter_2 type 
Print ( " url_parameter_2 value of type: " , of the type (url_parameter_2))    # is a list type

Results sections as follows:

 

 

3, the value

# Get the value of the sliced 
url_parameter_3 url_parameter_2 = [. 1 ]
 Print ( " url_parameter_3 values: " , url_parameter_3)

The value of the results:

 

 

To have been here this long list cents wanted to get out, but he bit through base64 encoded performs decode:

4, decoding

url_parameter_4 = base64.b64decode(url_parameter_3)

解码后的结果为：

 

 此时获取到的url_parameter_4的值类型为：bytes，其实是不便于我们获取shareParam这个值的，

5、转换类型

url_parameter_5 = json.loads(url_parameter_4)
print("转换类型后的url_parameter_5结果为：",url_parameter_5)

转换后的结果为 ：

 

 现在已经是个字典了 ，我们按照获取字典的值的方法去拿到shareParam的值

6、获取字典值

url_parameter_6 = url_parameter_5["shareParam"]
print(url_parameter_6)

获取的字典值为 ：

 

 这样就拿到了我最终想要的这个值，以供其他接口使用
