如何使用 python 访问 Gerrit Rest API

Question

首先，我对gerrit的了解有限。

我正在尝试使用 python 访问 Gerrit Rest API，但无法访问。我想获取与帐户相关的所有信息（提交、评论）。

from requests.auth import HTTPDigestAuth
from pygerrit2 import GerritRestAPI, HTTPBasicAuth
auth = HTTPBasicAuth('user', 'password')
from pygerrit2 import GerritRestAPI
rest = GerritRestAPI(url='https://xxx.xx.xxx.xxx.com/', auth = auth)
changes = rest.get("changes/?q=is:open&q=is:close&q=all&o=DETAILED_ACCOUNTS&o=ALL_REVISIONS&o=ALL_COMMITS&o=ALL_FILES&o=MESSAGES", headers={'Content-Type': 'application/json'})

我得到的错误是：

ConnectionError: HTTPSConnectionPool(host='xxx.xx.xxx.xxx.com', port=443): Max retries exceeded with url: /login/a/changes/?q=is:open&q=is:close&q=all&o=DETAILED_ACCOUNTS&o=ALL_REVISIONS&o=ALL_COMMITS&o=ALL_FILES&o=MESSAGES (Caused by NewConnectionError('<urllib3.connection.VerifiedHTTPSConnection object at 0x825bad0>: Failed to establish a new connection: [Errno 110] Connection timed out',))

如果我在 url 中复制粘贴查询，我可以获取信息，但不能通过 python。怎么做？如果问题不清楚，请发表评论/编辑。谢谢

您遇到来自请求库的连接错误（pygerrit2 是 dependent on requests) - it is occurring because your connection is timing out. To avoid this I recommend using a library like backoff。退避将捕获此连接错误并重试建立连接。这可以通过装饰器和导入轻松完成。

from requests.auth import HTTPDigestAuth
from pygerrit2 import GerritRestAPI, HTTPBasicAuth
import backoff
import requests

@backoff.on_exception(backoff.expo, 
                      requests.exceptions.ConnectionError,
                      max_time=10)
def makeGerritAPICall():
     auth = HTTPBasicAuth('user', 'password')
     rest = GerritRestAPI(url='https://xxx.xx.xxx.xxx.com/', auth = auth)
     changes = rest.get("changes/?q=is:open&q=is:close&q=all&o=DETAILED_ACCOUNTS&o=ALL_REVISIONS&o=ALL_COMMITS&o=ALL_FILES&o=MESSAGES", headers={'Content-Type': 'application/json'})

以下函数将在失败并引发 ConnectionError 之前重试发出任何遇到 ConnectionError 的请求 10 秒。

我建议访问退避 git README 文档，因为它们包含大量关于退避的有用信息。
