这是一个悲伤的故事

昨天，我司的python开发小哥刚准备下班陪女友共进晚餐，满心期待地盼着女友的回复，却接到女友晚上要加班的电话，满满的失落感涌上心头~

还有比这空欢喜更让人伤心难过的事情嘛！emmm还真有

不一会儿，小哥哥的女友发来了一张自称在加班并将背景模糊的自拍照，故事从这儿就开始了：

如下 ↓ ↓ ↓

null 女友留言说道：亲爱的，今晚一个人也要好好的吃晚饭哦，么么哒。小哥哥满脸疑惑，顿时受宠若惊，小女友这是咋啦，平时的她可是如此的“趾高气昂”，今天的热情让他满脸疑惑😦

不就是一张自拍照吗？这事儿又是为何最终让人难过呢，难道这不是女友在安慰我们的python开发小哥哥吗？

老铁们，你们要是这么想，接下来文章内容一定要细细品味、好好学习、深入研究……

为何女友要背景虚化？为何要特意发照片？明明平常工作不加班呀？

面对重重疑惑，我们的python开发小哥哥心生疑虑，决心运用所学python知识对女友自拍照编写了一段代码进行分析，不遛弯了，结果却显示照片的拍摄地址为「X X酒店」

null

绿帽从天而降，小哥哥这绿帽子是戴的稳稳的了，好在及时止损了，不然天天为老板996，最终换来的却是女友的669😭

想知道小哥哥是如何捍卫自己男人的尊严的，快拿小本本记下来，快拿小本本记下来，快拿小本本记下来！！！

重要事情说三遍

第一步：编写python脚本分析照片

通过下载发来的照片原图，利用python来编写全文的脚本文件，由此读取照片中拍摄的详细地址（地址可以详细到具体的街道和酒店名称）

第二步：引入exifread模块

再安装python中的exifread模块，用于照片分析

pip install exifread 安装exfriead模块。

PS C:\WINDOWS\system32> pip install exifread
Collecting exifread
  Downloading ExifRead-2.3.2-py3-none-any.whl (38 kB)
Installing collected packages: exifread
Successfully installed exifread-2.3.2
PS C:\WINDOWS\system32> pip install json

第三步：读取GPS定位的经纬度信息
通过Python的exifread模块，可以读取照片中隐藏的经纬度信息（其实我们日常的照片中往往隐藏着很多的秘密，包括拍摄时间以及经纬度等）

#读取照片的GPS经纬度信息
def find_GPS_image(pic_path):
    GPS = {}
    date = ''
    with open(pic_path, 'rb') as f:
        tags = exifread.process_file(f)
        for tag, value in tags.items():
            #纬度
            if re.match('GPS GPSLatitudeRef', tag):
                GPS['GPSLatitudeRef'] = str(value)
            #经度
            elif re.match('GPS GPSLongitudeRef', tag):
                GPS['GPSLongitudeRef'] = str(value)
            #海拔
            elif re.match('GPS GPSAltitudeRef', tag):
                GPS['GPSAltitudeRef'] = str(value)
            elif re.match('GPS GPSLatitude', tag):
                try:
                    match_result = re.match('\[(\w*),(\w*),(\w.*)/(\w.*)\]', str(value)).groups()
                    GPS['GPSLatitude'] = int(match_result[0]), int(match_result[1]), int(match_result[2])
                except:
                    deg, min, sec = [x.replace(' ', '') for x in str(value)[1:-1].split(',')]
                    GPS['GPSLatitude'] = latitude_and_longitude_convert_to_decimal_system(deg, min, sec)
            elif re.match('GPS GPSLongitude', tag):
                try:
                    match_result = re.match('\[(\w*),(\w*),(\w.*)/(\w.*)\]', str(value)).groups()
                    GPS['GPSLongitude'] = int(match_result[0]), int(match_result[1]), int(match_result[2])
                except:
                    deg, min, sec = [x.replace(' ', '') for x in str(value)[1:-1].split(',')]
                    GPS['GPSLongitude'] = latitude_and_longitude_convert_to_decimal_system(deg, min, sec)
            elif re.match('GPS GPSAltitude', tag):
                GPS['GPSAltitude'] = str(value)
            elif re.match('.*Date.*', tag):
                date = str(value)
    return {'GPS_information': GPS, 'date_information': date}

第四步：利用百度API将GPS转地址
最后我们再通过调用百度的API接口，将获得的GPS经纬度信息转换为可定位读取的具体地址信息

def find_address_from_GPS(GPS):
    secret_key = 'zbLsuDDL4CS2U0M4KezOZZbGUY9iWtVf'
    if not GPS['GPS_information']:
        return '该照片无GPS信息'
    #经纬度信息
    lat, lng = GPS['GPS_information']['GPSLatitude'], GPS['GPS_information']['GPSLongitude']
    baidu_map_api = "http://api.map.baidu.com/geocoder/v2/?ak={0}&callback=renderReverse&location={1},{2}s&output=json&pois=0".format(
        secret_key, lat, lng)
    response = requests.get(baidu_map_api)
    #百度API转换成具体的地址
    content = response.text.replace("renderReverse&&renderReverse(", "")[:-1]
    print(content)
    baidu_map_address = json.loads(content)
    #将返回的json信息解析整理出来
    formatted_address = baidu_map_address["result"]["formatted_address"]
    province = baidu_map_address["result"]["addressComponent"]["province"]
    city = baidu_map_address["result"]["addressComponent"]["city"]
    district = baidu_map_address["result"]["addressComponent"]["district"]
    location = baidu_map_address["result"]["sematic_description"]
    return formatted_address,province,city,district,location

if __name__ == '__main__':
    GPS_info = find_GPS_image(pic_path='C:/女友自拍.jpg')
    address = find_address_from_GPS(GPS=GPS_info)
    print("拍摄时间：" + GPS_info.get("date_information"))
    print('照片拍摄地址:' + str(address))

接下来就静待开奖……
恭喜喜提绿帽一枚
