遍历 Rocket.Chat API

Question

Python 3.7.2 PyCharm

我对 Python 和 API 交互还很陌生；我正在尝试遍历 Rocket Chat 的 API，特别是拉出用户电子邮件地址。与我能找到的几乎所有示例不同，Rocket Chat 不使用任何类型的构造，如 "Next" - 它使用计数和偏移量，我实际上虽然可能会让这更容易。我已经设法完成了这项工作的第一部分，遍历 JSON 并获取电子邮件。我需要做的是遍历 API 端点 - 这就是我运行遇到的一些问题。
我看过这个答案因为它似乎非常接近我想要的，但我无法让它正常工作。

下面的代码是我现在拥有的；显然，这还没有对 API 端点进行任何循环，它只是对返回的 json.

进行循环

import os
import csv
import requests
import json

url = "https://rocketchat.internal.net"
login = "/api/v1/login"
rocketchatusers = "/api/v1/users.list"
#offset = "?count=500&offset=0"


class API:

    def userlist(self, userid, token):
        headers = {'X-Auth-Token': token, 'X-User-Id': userid}
        rocketusers = requests.get(url + rocketchatusers, headers=headers, verify=False)
        print('Status Code:' + str(rocketusers.status_code))
        print('Content Type:' + rocketusers.headers['content-type'])
        userlist = json.loads(rocketusers.text)
        x = 0
        y = 0
        emails = open('emails', 'w')
        while y == 0:
            try:
                for i in userlist:
                    print(userlist['users'][x]['emails'][0]['address'], file=emails)
                    # print(userlist['users'][x]['emails'][0]['address'])
                    x += 1
            except KeyError:
                print("This user has no email address", file=emails)
                x += 1
            except IndexError:
                print("End of List")
                emails.close()
                y += 1

我尝试过的和我想做的是简单的 FOR 循环。实际上可能有很多方法可以做我想做的事情，我只是不知道它们。

像这样：

import os
import csv
import requests
import json

url = "https://rocketchat.internal.net"
login = "/api/v1/login"
rocketchatusers = "/api/v1/users.list"
offset = "?count=500&offset="+p
p = 0

class API:

    def userlist(self, userid, token):
        headers = {'X-Auth-Token': token, 'X-User-Id': userid}
        rocketusers = requests.get(url + rocketchatusers+offset, headers=headers, verify=False)

        for r in rocketusers:
            print('Status Code:' + str(rocketusers.status_code))
            print('Content Type:' + rocketusers.headers['content-type'])
            userlist = json.loads(rocketusers.text)
            x = 0
            y = 0
            emails = open('emails', 'w')
            while y == 0:
                try:
                    for i in userlist:
                        print(userlist['users'][x]['emails'][0]['address'], file=emails)
                        # print(userlist['users'][x]['emails'][0]['address'])
                        x += 1
                except KeyError:
                    print("This user has no email address", file=emails)
                    x += 1
                except IndexError:
                    print("End of List")
                    emails.close()
                    y += 1
        p += 500

现在，显然这行不通，否则我不会 posting，但问题是它为何行不通。获取报告的错误是我无法连接 INT，而应该是 STR。好的。当我尝试类似的事情时：

str(p = 0) 我收到类型错误。我也尝试了很多其他的东西，其中很多都是愚蠢的，比如 p = []、p = {} 和其他更激进的想法。

URL，如果不是所有的变量和连接看起来像这样：

https://rocketchat.internal.net/api/v1/users.list?count=500&offset=0
https://rocketchat.internal.net/api/v1/users.list?count=500&offset=500
https://rocketchat.internal.net/api/v1/users.list?count=500&offset=1000
https://rocketchat.internal.net/api/v1/users.list?count=500&offset=1500

我觉得我缺少了一些非常简单的东西。我有理由相信答案就在对我列出的 post 的回应中，但我无法让它工作。

所以，在四处询问之后，我发现我一直在正确的道路上解决这个问题，我只是在错误的地方尝试了。这是我最终得到的结果：

def userlist(self, userid, token):
    p = 0
    while p <= 7500:
        if not os.path.exists('./emails'):
            headers = {'X-Auth-Token': token, 'X-User-Id': userid}
            rocketusers = requests.get(url + rocketchatusers + offset + str(p), headers=headers, verify=False)
            print('Status Code:' + str(rocketusers.status_code))
            print('Content Type:' + rocketusers.headers['content-type'])
            print('Creating the file "emails" to use to compare against list of regulated users.')
            print(url + rocketchatusers + offset + str(p))
            userlist = json.loads(rocketusers.text)
            x = 0
            y = 0
            emails = open('emails', 'a+')
            while y == 0:
                try:
                    for i in userlist:
                        #print(userlist['users'][x]['emails'][0]['address'], file=emails)
                        print(userlist['users'][x]['ldap'], file=emails)
                        print(userlist['users'][x]['username'], file=emails)
                        x += 1
                except KeyError:
                    x += 1
                except IndexError:
                    print("End of List")
                    emails.close()
                    p += 50
                    y += 1
        else:
            headers = {'X-Auth-Token': token, 'X-User-Id': userid}
            rocketusers = requests.get(url + rocketchatusers + offset + str(p), headers=headers, verify=False)
            print('Status Code:' + str(rocketusers.status_code))
            print('Content Type:' + rocketusers.headers['content-type'])
            print('Populating file "emails" - this takes a few moments, please be patient.')
            print(url + rocketchatusers + offset + str(p))
            userlist = json.loads(rocketusers.text)
            x = 0
            z = 0
            emails = open('emails', 'a+')
            while z == 0:
                try:
                    for i in userlist:
                        #print(userlist['users'][x]['emails'][0]['address'], file=emails)
                        print(userlist['users'][x]['ldap'], file=emails)
                        print(userlist['users'][x]['username'], file=emails)
                        x += 1
                except KeyError:
                    x += 1
                except IndexError:
                    print("End of List")
                    emails.close()
                    p += 50
                    z += 1

这项工作仍在进行中，不幸的是，这不是协作的途径，稍后我可能 post 将它发送到 GitHub 以便其他人可以看到它。
