Mysql json read data into the flask frame format API

Research for a day because of the need to get data from the database and then converted into json format out to expose API

Found a piece of data is easy, two more than I actually do for so long at any rate out first posted about the update later

mysql of the operation is relatively easy https://pynative.com/python-mysql-select-query-to-fetch-data/

flask also a lot easier to reference

Mysql extraction field name but is the least seen - " https://www.jianshu.com/p/057a784febb9

= cur.description Fields                # to get the field name in the query results column, SQL is used aliases If the query shown here aliases.       
cur.close () 
conn.Close () 

# the Main 
the column_list = []                         # define a list of field names 
for I in Fields: 
    column_list.append (I [0])　　   # extract field names, append to the list 
# Print # listing the column_list display results: [ 'id', 'NAME ', 'LOCAL', 'mobile', 'CreateTime']

select out of the list and the field names combined to form a dict

for row in Result:
         # define Python Dictionary 
        Data = {}
         # The row each element, is added to the dictionary. 
        for I in Range (len (the column_list)): 
            Data [the column_list [I]] = Row [I]
         # Data [the column_list [0]] = Row [0] 
        # # the Python field format and json field format conversion 
        # Data [the column_list [. 1]] = STR (Row [. 1]) 
        # Data [the column_list [2]] = STR (Row [2]) 
        # Data [the column_list [. 3]] = STR (Row [. 3])

A lot of people refer to code

https://www.cnblogs.com/yufeihlf/p/6004124.html - but this one's own header to knock too much trouble

# Converting the data into a tuple list of types, each type of data element dictionary is: [{ 'field 1': 'value field 1', '2 field': 'field value of 2', ..., ' field N: field value N '}, {} the second data, ..., N-th data {}] 
        for Row in data:   
            Result = {} 
            Result [ ' nm ' ] = Row [0]   
            Result [ ' DC ' ] = Row [. 1 ]   
            Result [ ' IU ' ] = Row [2 ]   
            Result [ ' IT ' ] = STR (Row [. 3 ])    
            Result [ ' OG '] = str(row[4])   
            result['mt'] = str(row[5])   
            result['pn'] = row[6]  
            result['du'] = row[7]  
            result['am'] = row[8]  
            result['mc'] = str(row[9]) 
            result['vc'] = str(row[10]) 
            result['vn'] = row[11]  
            result[''sm] = Row [12 is ] 
            Result [ ' SE ' ] = STR (Row [13 is ]) 
            Result [ ' AO ' ] = STR (Row [14 ])     
            jsonData.append (Result) 
            Print U ' into a list of raw data dictionaries : ' , jsonData

My ultimate goal is Call http://127.0.0.1:5000/north/getSpace time to return json value of my space

But not optimized to fully realize my request. . One day come up pretty well limited level
