Google cloud storage file 集成 - AI 开发中文文档

Google Cloud Storage 是一个托管服务，用于存储非结构化数据。

这涵盖了如何从 Google Cloud Storage (GCS) file object (blob) 加载文档对象。

pip install -qU  langchain-google-community[gcs]

from langchain_google_community import GCSFileLoader

loader = GCSFileLoader(project_name="aist", bucket="testing-hwc", blob="fake.docx")

loader.load()

You might receive a "quota exceeded" or "API not enabled" error. We recommend you rerun `gcloud auth application-default login` and make sure a quota project is added. Or you can use service accounts instead. For more information about service accounts, see https://cloud.google.com/docs/authentication/

如果您想使用其他加载器，可以提供一个自定义函数，例如：

from langchain_community.document_loaders import PyPDFLoader


def load_pdf(file_path):
    return PyPDFLoader(file_path)


loader = GCSFileLoader(
    project_name="aist", bucket="testing-hwc", blob="fake.pdf", loader_func=load_pdf
)
