Shell借助curl调用接口结合Python解析Python案例

需求说明：

实现通过shell调用接口，并实现json的解析。

解决方法：

 本案例按照两步来实现：

1、借助curl命令调用接口，上传本地json文件

2、对json文件利用python进行解析，生成结构化文本

Step1：Shell通过curl调用接口

#!/bin/bash
input_file=/root/workbase/id_card.txt
output_folder=/root/workbase/curl

cat $input_file | while read myline
do 
 echo $myline
 token_wb=`curl --location 'http://192.168.56.2:7070/oauth/token?client_id=xw&client_secret=2w'  --header 'Content-Type: application/json' --data '{}'`
 token2=$(echo $token_wb| awk -F ':' '{print $2}' |awk -F ',' '{print $1}'| sed 's/\"//g')
 filename=`echo $myline | sed "s/[\']//g"`
 curl -X POST --location 'http://192.168.56.2:7070/service/api/q2/dataexchangeserver/apiPayload/fe2/qx?client_id=fc&access_token='$token2''  --header 'Content-Type: application/json;charset=utf-8' --header 'Accept: application/json;charset=utf-8' --data '{"messageSequence":"01","condition":"ID='$myline' and STATUS='\''有效'\''","maxReturnNum":100,"orderParafs":{"ID":"desc"}}'| cat > $output_folder/$filename.json
 ##echo $filename
 ###sleep `expr $RANDOM % 2 + 1`
done

Step2：Python对Json进行解析

def traverse_dir(path):
    try:
        files = glob.glob(os.path.join(path, "*"))
        for file in files:
            if os.path.isdir(file):
                print("文件夹：", file)
                traverse_dir(file)
            else:
                    f = open(file, 'r', encoding='UTF8')
                    data = json.load(f)
                    with open('D:/household.txt', 'a', encoding='utf-8') as fw:
                        for k,v in data['result'].items():
                            if k == 'data':
                                print(len(v['results']))
                                for i in range(len(v['results'])):
									data = v['results'][i]
									NAME = data.get('NAME')
									ID = data.get('ID')
									STATUS = data.get('STATUS')
									ADDR = data.get('ADDR')
									str = NAME + '\t' + ID + '\t' + STATUS + '\t' + ADDR
									fw.write(str + '\n')
    except KeyError as e:
        print("There are missing fields in the user object: ", e)
    except FileNotFoundError as e:
        print("File is not found: ",e)
    except Exception:
        print("Error file \t", file)
    finally:
        f.close()
        fw.close()


traverse_dir('D:\\household')

#JSON实例样例：

{
	"code": "0",
	"message": "查询成功",
	"result": {
		"status": 200,
		"msg": "正常",
		"messageSequence": "01",
		"data": {
			"totalRows": "1",
			"results": [
				{
					"NAME": "张三",
					"ID": "234513",
					"ADDR": "北京市创新大道1000号",
					"PERSON_STAT_NAME": "有效",
				}
			]
		},
		"qtime": 1200
	}
