# Google cloud storage file 集成

> 使用 LangChain Python 集成 Google cloud storage file 文档加载器

> [Google Cloud Storage](https://en.wikipedia.org/wiki/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。

```python theme={null}
pip install -qU  langchain-google-community[gcs]
```

```python theme={null}
from langchain_google_community import GCSFileLoader
```

```python theme={null}
loader = GCSFileLoader(project_name="aist", bucket="testing-hwc", blob="fake.docx")
```

```python theme={null}
loader.load()
```

```text theme={null}
/Users/harrisonchase/workplace/langchain/.venv/lib/python3.10/site-packages/google/auth/_default.py:83: UserWarning: Your application has authenticated using end user credentials from Google Cloud SDK without a quota project. 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/
  warnings.warn(_CLOUD_SDK_CREDENTIALS_WARNING)
```

```python theme={null}
[Document(page_content='Lorem ipsum dolor sit amet.', lookup_str='', metadata={'source': '/var/folders/y6/8_bzdg295ld6s1_97_12m4lr0000gn/T/tmp3srlf8n8/fake.docx'}, lookup_index=0)]
```

如果您想使用其他加载器，可以提供一个自定义函数，例如：

> [!WARNING]
>
> `langchain-community`包已不再维护。从`langchain_community`导入的示例可能过时或无法使用。请谨慎使用。

```python theme={null}
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
)
```
