Пакетная загрузка фото ArcOnline - Python Ошибка имени

0 голосов
/ 21 января 2020

Я пытаюсь загрузить фотографии из слоя ArcOnline. Я хотел бы определить те, где атрибут Creator = значение Speci c, а затем сохранить все фотографии из одной точки в одной папке с objectid в качестве заголовка этой папки, а затем со значениями атрибутов objectid и asset_type в качестве фотографии имя "objid_assettype".

Я сталкиваюсь с ошибкой NameEr. Вот код, над которым я работаю, за исключением информации о слое и имени пользователя. 

import requests import json import os import sys

# ARCGIS ONLINE USERNAME AND PASSWORD def get_new_sh():
    username = ""
    password = ""
    config = {'username': username, 'password': password}
    #token = securityhandlerhelper.securityhandlerhelper(config)

    token = ''
    #sh = arcrest.AGOLTokenSecurityHandler()
    return token

def get_objectid_ID(objID, token):
    # LAYER SERVICE URL
    base_url = ''
    # BUDILING COMPLETE URL
    query_url = base_url + str(objID) + '?token=' + str(token) + '&f=json'
    # ISSUING THE REST REQUEST
    r = requests.get(query_url)
    # loading the response into a dictionary
    response_dic = json.loads(r.content)
    return (response_dic['feature']['attributes']['OBJECTID'], response_dic['feature']['attributes']['Asset_Type'], response_dic['feature']['attributes']['Creator'])



def save_pics(objID, attachment_list, OBJECTID, Asset_Type, token, results_file):

    cwd = os.getcwd()
    Asset_Type = str(Asset_Type).replace('/','_')
    Asset_Type = str(Asset_Type).replace(' ', '_')
    new_cwd = cwd + '\\' + str(OBJECTID) + '_' + str(Asset_Type)

    if os.path.exists(new_cwd):
        print('skipped:' + new_cwd)
        results_file.write('skipped:' + new_cwd + ",objid: " + str(objID) + "\n")
        return
    os.makedirs(new_cwd)
    print('pulled:' + new_cwd)
    results_file.write('pulled:' + new_cwd + ",objid: " + str(objID) + "\n")

    base_url = ''
    query_url = base_url + str(objID) + '/attachment/'

    pic_count = 1
    for pic in attachment_list:

        name = str(objID) + '_' + str(pic['name'])

        complete_name = new_cwd + '\\' + name
        pic_url = query_url + str(pic['id']) + '?token=' + str(token)
        r = requests.post(pic_url, stream=True)
        with open(complete_name, 'wb') as f:
            for chunk in r.iter_content(1024):
                f.write(chunk)
        del r
        pic_count += 1
