Question

是否可以从dict而非文件中加载凭证？这将使在云功能中使用短脚本更加容易，因为这样就无需上传文件了。通常，授权是这样的：

const fs = require('fs');
requ().then((result) => {
    //here result is the file's representing string
    const path = __dirname + '/tempFiles' + Date.now(); // a temporary file to send it 
    fs.writeFile(path, result, function(err) {
        if(err) throw err;
        return res.sendFile(path);
    })
});

如果凭据存储在这样的变量中：

import pygsheets
gc = pygsheets.authorize(service_file='client_secret.json')

是否可以用secret = { "type": "service_account", "project_id": "XXXXXXXXXX", "private_key_id": "XXXXXXXXXX", "private_key": "XXXXXXXXXX" "client_email": "XXXXXXXXXX", "client_id": "XXXXXXXXXX", "auth_uri": "https://accounts.google.com/o/oauth2/auth", "token_uri": "https://oauth2.googleapis.com/token", "auth_provider_x509_cert_url": "https://www.googleapis.com/oauth2/v1/certs", "client_x509_cert_url": "XXXXXXXXXX" }而不是custom_credentials加载它们？ docs除了使用“此选项将忽略任何其他参数”之外，没有提供任何使用说明。以下代码：

service_file

引发以下错误：

import pygsheets
gc = pygsheets.authorize(custom_credentials=secret)

还有另一种方法吗？例如，在AttributeError: 'dict' object has no attribute 'before_request'中，有以下选项：

gspread

有什么建议吗？谢谢!!!

就这样做了！因此，我们最终要做的是编写一个tempfile，然后加载进行授权。下面的工作示例：

import tempfile

def _google_creds_as_file():
    temp = tempfile.NamedTemporaryFile()
    temp.write(json.dumps({
        "type": "service_account",
        "project_id": "xxxx-yyy",
        "private_key_id": "xxxxxxx",
        "private_key": "-----BEGIN PRIVATE KEY----------END PRIVATE KEY-----\n",
        "client_email": "xxx@yyyy.iam.gserviceaccount.com",
        "client_id": "xxxxx",
        "auth_uri": "https://accounts.google.com/o/oauth2/auth",
        "token_uri": "https://oauth2.googleapis.com/token",
        "auth_provider_x509_cert_url": "https://www.googleapis.com/oauth2/v1/certs",
        "client_x509_cert_url": "https://www.googleapis.com/robot/v1/metadata/x509/xxxxx%40xxxx.iam.gserviceaccount.com"
    }))
    temp.flush()
    return temp

creds_file = _google_creds_as_file()
gc = pygsheets.authorize(service_account_file=creds_file.name)

感谢@kontinuity的建议。经过一番挖掘，我发现实际上已经有一个拉取请求： https://github.com/nithinmurali/pygsheets/pull/345

在authorization.py中有一个名为service_account_env_var的新选项。刚刚尝试过，效果很好。

Answer 3

custom_credentials应该是here中提到的凭据对象。如果您不想创建tmp文件，则可以直接从json创建对象。

SCOPES = ('https://www.googleapis.com/auth/spreadsheets', 'https://www.googleapis.com/auth/drive')
service_account_info = json.loads(secret)
my_credentials = service_account.Credentials.from_service_account_info(service_account_info, scopes=SCOPES)

pygsheets-从dict而不是从文件加载凭据
