`request.raw` 属性是 Flask 中 `Request` 对象的一个属性,它返回一个类文件对象,可以用来读取请求主体中的原始数据。
例如,如果发送了一个 POST 请求,该请求包含一个 JSON 格式的主体,可以使用以下代码读取原始数据:
```python
from flask import Flask, request
app = Flask(__name__)
@app.route('/example', methods=['POST'])
def example():
raw_data = request.raw.read()
# 在这里对原始数据进行处理
return 'Success'
```
在上面的代码中,`request.raw.read()` 方法将返回一个字节串对象,包含请求主体中的原始数据。可以使用这个字节串对象来处理请求中的数据。

var body = pm.request.body.raw
As an AI language model, I cannot access the context of the request, so I cannot provide a specific answer. However, assuming that this code snippet is written in JavaScript, it is likely that `pm` refers to the Postman object, which is used to manage requests and responses in the Postman app or in a Postman collection.
The `request` object is a property of the `pm` object, and it contains information about the current request being sent. The `body` property of the `request` object contains the data that will be sent in the request body.
The `raw` property of the `body` object returns the raw content of the request body as a string. This can be useful if you need to manipulate the request body before sending the request, or if you want to inspect the content of the request body for debugging purposes.
So, `pm.request.body.raw` would be used to get the raw content of the request body in a Postman script.
request.request
request.Request类是Python中urllib库中的一个类,用于构建HTTP请求。它的作用是模拟浏览器发送请求,可以设置请求的URL、数据、请求方法、请求头等信息。在进行爬虫时,网站往往会有反爬虫机制,如果不使用request.Request类来伪装爬虫程序,网站可能会拒绝访问或发送假数据来迷惑爬虫。通过设置请求头,使用request.Request类可以将爬虫程序包装为一个浏览器,从而避免被网站阻碍访问。
在实际应用中,可以根据需要设置请求头的内容,包括User-Agent、Referer、Cookie等,以便更好地模拟浏览器行为。使用request.Request类可以实现更精准的爬取和数据提取。
