|
|
|
|||
|
|
http接口可参考原文档：https://github.com/infiniflow/ragflow/blob/main/docs/references/http_api_reference.md

# 1. 依赖安装/密钥准备
|
|||
|
|
使用python调用API接口，需要安装`ragflow-sdk`依赖，可用pip进行安装：
|
|||
|
|
```python
|
|||
|
|
pip install ragflow-sdk
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
之后，需要在API菜单中，创建一个`API KEY`，复制该值，后续要用到。
|
|||
|
|
|
|||
|
|
# 2. 创建聊天(Create chat completion)
|
|||
|
|
通过OpenAI的API为选择助理进行聊天。
|
|||
|
|
|
|||
|
|
这里的示例需要修改三个值：
|
|||
|
|
- model：模型名称
|
|||
|
|
- api_key：替换成自己的api_key，后文同理
|
|||
|
|
- base_url：最后面一串为具体助手的`dialogId`，可直接从url中查看获取
|
|||
|
|
|
|||
|
|
可选参数：stream，用于指定是否采用流式输出
|
|||
|
|
|
|||
|
|
```python
|
|||
|
|
from openai import OpenAI
|
|||
|
|
|
|||
|
|
model = "deepseek-r1:1.5b"
|
|||
|
|
client = OpenAI(api_key="ragflow-I0NmRjMWNhMDk3ZDExZjA5NTA5MDI0Mm", base_url=f"http://localhost/api/v1/chats_openai/ec69b3f4fbeb11ef862c0242ac120002")
|
|||
|
|
|
|||
|
|
completion = client.chat.completions.create(
|
|||
|
|
model=model,
|
|||
|
|
messages=[
|
|||
|
|
{"role": "system", "content": "你是一个乐于助人的助手"},
|
|||
|
|
{"role": "user", "content": "你是谁？"},
|
|||
|
|
],
|
|||
|
|
stream=True
|
|||
|
|
)
|
|||
|
|
|
|||
|
|
stream = True
|
|||
|
|
if stream:
|
|||
|
|
for chunk in completion:
|
|||
|
|
print(chunk)
|
|||
|
|
else:
|
|||
|
|
print(completion.choices[0].message.content)
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
如果使用 `Infinity`，作为检索引擎，实测会发现遇到报错，等待官方后续完善支持。
|
|||
|
|

# 3. 知识库管理(DATASET MANAGEMENT)
|
|||
|
|
## 3.1 创建知识库(Create dataset)
|
|||
|
|
|
|||
|
|
创建一个名称为`kb_1`的知识库
|
|||
|
|
```python
|
|||
|
|
from ragflow_sdk import RAGFlow
|
|||
|
|
|
|||
|
|
api_key = "ragflow-I0NmRjMWNhMDk3ZDExZjA5NTA5MDI0Mm"
|
|||
|
|
base_url = "http://localhost:9380"
|
|||
|
|
|
|||
|
|
rag_object = RAGFlow(api_key=api_key, base_url=base_url)
|
|||
|
|
dataset = rag_object.create_dataset(name="kb_1")
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
|
|||
|
|
|
|||
|
|
|
|||
|
|
|
|||
|
|
|
|||
|
|
## 3.2 查询知识库(List datasets)
|
|||
|
|
根据名称，查询知识库信息
|
|||
|
|
```python
|
|||
|
|
from ragflow_sdk import RAGFlow
|
|||
|
|
|
|||
|
|
api_key = "ragflow-I0NmRjMWNhMDk3ZDExZjA5NTA5MDI0Mm"
|
|||
|
|
base_url = "http://localhost:9380"
|
|||
|
|
|
|||
|
|
rag_object = RAGFlow(api_key=api_key, base_url=base_url)
|
|||
|
|
|
|||
|
|
# 查询所有知识库
|
|||
|
|
for dataset in rag_object.list_datasets():
|
|||
|
|
print(dataset)
|
|||
|
|
# 根据name查询某一知识库
|
|||
|
|
dataset = rag_object.list_datasets(name = "kb_1")
|
|||
|
|
print(dataset[0])
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
## 3.3 删除知识库(Delete datasets)
|
|||
|
|
删除指定知识库
|
|||
|
|
|
|||
|
|
只能根据知识库id进行删除，无name接口，id通过上一步查询得到
|
|||
|
|
|
|||
|
|
```python
|
|||
|
|
from ragflow_sdk import RAGFlow
|
|||
|
|
|
|||
|
|
api_key = "ragflow-I0NmRjMWNhMDk3ZDExZjA5NTA5MDI0Mm"
|
|||
|
|
base_url = "http://localhost:9380"
|
|||
|
|
|
|||
|
|
rag_object = RAGFlow(api_key=api_key, base_url=base_url)
|
|||
|
|
rag_object.delete_datasets(ids = ["50f80d7c099111f0ad0e0242ac120006"])
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
## 3.4 更新知识库配置(Update dataset)
|
|||
|
|
更新已存在的知识库配置
|
|||
|
|
|
|||
|
|
这里原始文档给的示例存在小问题，`rag_object.list_datasets`返回的是一个list，因此需要取出list中第一项，对于该问题，我提交了一个PR：Fix: python_api_reference.md update dataset bug
|
|||
|
|
|
|||
|
|
PR链接：https://github.com/infiniflow/ragflow/pull/6527
|
|||
|
|
|
|||
|
|
官方响应还是挺快的，晚上提交的，第二天上午review，下午就merge了。
|
|||
|
|
|
|||
|
|
|
|||
|
|
```python
|
|||
|
|
from ragflow_sdk import RAGFlow
|
|||
|
|
|
|||
|
|
api_key = "ragflow-I0NmRjMWNhMDk3ZDExZjA5NTA5MDI0Mm"
|
|||
|
|
base_url = "http://localhost:9380"
|
|||
|
|
|
|||
|
|
rag_object = RAGFlow(api_key=api_key, base_url=base_url)
|
|||
|
|
dataset = rag_object.list_datasets(name="kb_1")
|
|||
|
|
dataset = dataset[0]
|
|||
|
|
dataset.update({"chunk_method":"manual"})
|
|||
|
|
```

# 4. 文件管理 (FILE MANAGEMENT WITHIN DATASET)
|
|||
|
|
|
|||
|
|
## 4.1 上传文件(Upload documents)
|
|||
|
|
上传文件进入到`kb_1`的知识库
|
|||
|
|
|
|||
|
|
两个主要参数：
|
|||
|
|
|
|||
|
|
- display_name：文件名
|
|||
|
|
- blob：文件的二进制内容
|
|||
|
|
|
|||
|
|
```python
|
|||
|
|
from ragflow_sdk import RAGFlow
|
|||
|
|
|
|||
|
|
api_key = "ragflow-I0NmRjMWNhMDk3ZDExZjA5NTA5MDI0Mm"
|
|||
|
|
base_url = "http://localhost:9380"
|
|||
|
|
|
|||
|
|
rag_object = RAGFlow(api_key=api_key, base_url=base_url)
|
|||
|
|
dataset = rag_object.list_datasets(name="kb_1")
|
|||
|
|
dataset = dataset[0]
|
|||
|
|
dataset.upload_documents([{"display_name": "1.txt", "blob": open('1.txt',"rb").read()}])
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
|
|||
|
|
## 4.2 更新文件配置(Upload documents)
|
|||
|
|
更新已有文件的配置信息
|
|||
|
|
|
|||
|
|
原文档这里也有个小错误：`doc.update`外层多一个list，这里直接进行修正。
|
|||
|
|
|
|||
|
|
```python
|
|||
|
|
from ragflow_sdk import RAGFlow
|
|||
|
|
|
|||
|
|
api_key = "ragflow-I0NmRjMWNhMDk3ZDExZjA5NTA5MDI0Mm"
|
|||
|
|
base_url = "http://localhost:9380"
|
|||
|
|
|
|||
|
|
rag_object = RAGFlow(api_key=api_key, base_url=base_url)
|
|||
|
|
dataset = rag_object.list_datasets(name="kb_1")
|
|||
|
|
dataset = dataset[0]
|
|||
|
|
doc = dataset.list_documents(id="7c5ea41409f811f0b9270242ac120006")
|
|||
|
|
doc = doc[0]
|
|||
|
|
doc.update({"parser_config": {"chunk_token_count": 256}})
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
## 4.3 下载文件(Download document)
|
|||
|
|
根据documents id，下载文件
|
|||
|
|
|
|||
|
|
```python
|
|||
|
|
from ragflow_sdk import RAGFlow
|
|||
|
|
|
|||
|
|
api_key = "ragflow-I0NmRjMWNhMDk3ZDExZjA5NTA5MDI0Mm"
|
|||
|
|
base_url = "http://localhost:9380"
|
|||
|
|
|
|||
|
|
rag_object = RAGFlow(api_key=api_key, base_url=base_url)
|
|||
|
|
dataset = rag_object.list_datasets(name="kb_1")
|
|||
|
|
dataset = dataset[0]
|
|||
|
|
doc = dataset.list_documents(id="7c5ea41409f811f0b9270242ac120006")
|
|||
|
|
doc = doc[0]
|
|||
|
|
open("ragflow.txt", "wb+").write(doc.download())
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
这是按照文档实现的方法，但存在问题，`doc.download()`返回的是json数据，而不是二进制数据，会导致写入失败，尚未修复。
|
|||
|
|
|
|||
|
|
## 4.4 删除文件(Delete documents)
|
|||
|
|
根据documents id，删除文件
|
|||
|
|
|
|||
|
|
```python
|
|||
|
|
from ragflow_sdk import RAGFlow
|
|||
|
|
|
|||
|
|
api_key = "ragflow-I0NmRjMWNhMDk3ZDExZjA5NTA5MDI0Mm"
|
|||
|
|
base_url = "http://localhost:9380"
|
|||
|
|
|
|||
|
|
rag_object = RAGFlow(api_key=api_key, base_url=base_url)
|
|||
|
|
dataset = rag_object.list_datasets(name="kb_1")
|
|||
|
|
dataset = dataset[0]
|
|||
|
|
dataset.delete_documents(ids=["7c5ea41409f811f0b9270242ac120006"])
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
|
|||
|
|
|
|||
|
|

|||
|
|
传入documents id，批量解析文件
|
|||
|
|
|
|||
|
|
```python
|

|
|||
|
|
base_url = "http://localhost:9380"
|
|||
|
|
|
|||
|
|
rag_object = RAGFlow(api_key=api_key, base_url=base_url)
|
