 +
 +
构造url
 +
 +
我们常常将http请求的参数以url的query string的形式进行发送，传统的做法是我们使用拼凑的方式构造这个url。例如我们需要构造以下这个url：
 +
 +
    http://httpbin.org/get?key1=value1&key2=value2
 +
 +
使用reqeuets，你可以方便地构造这个url，而不用手工拼凑。你只需要将这些参数和值构造一个字典，然后将这个字典传给params参数即可
 +
 +
传递一个字典给data参数
 +
 +
>>> import requests
 +
>>> payload={"key1":"value1","key2":"value2"}
 +
>>> r=requests.post("https://httpbin.org/post")
 +
>>> r1=requests.post("https://httpbin.org/post",data=payload)
 +
>>>
 +
 +
有没有参考的不同
 +

==requests模块-发送带参数的请求==
 +
1. url 中直接带参数
 +
2. 使用params 参数
 +
 +
返回值类型
 +
 +
    r.content：返回的是响应内容的二进制形式，类型为 bytes。这意味着它可以包含任何类型的数据，比如图片、音频、视频等二进制文件，也可以是文本数据。
 +
    r.text：返回的是响应内容的字符串形式，类型为 str。它会尝试根据响应的 Content-Type 头部信息或自动检测来对二进制数据进行解码。
 +
 +
2. 代码示例及区别展示
 +
 +
python
 +
 +
import requests
 +
 +
# 发送 HTTP 请求
 +
r = requests.get('https://www.example.com')
 +
 +
# 使用 r.content 获取二进制响应内容
 +
content = r.content
 +
print(type(content))  # 输出: <class 'bytes'>
 +
 +
# 使用 r.text 获取字符串响应内容
 +
text = r.text
 +
print(type(text))  # 输出: <class 'str'>

响应格式

content 返回是的二进制的内容，text返回是字符串格式的内容，json()返回的是序列化的内容。

post

构造url

我们常常将http请求的参数以url的query string的形式进行发送，传统的做法是我们使用拼凑的方式构造这个url。例如我们需要构造以下这个url：

    http://httpbin.org/get?key1=value1&key2=value2

使用reqeuets，你可以方便地构造这个url，而不用手工拼凑。你只需要将这些参数和值构造一个字典，然后将这个字典传给params参数即可

传递一个字典给data参数

>>> import requests 
>>> payload={"key1":"value1","key2":"value2"}
>>> r=requests.post("https://httpbin.org/post")
>>> r1=requests.post("https://httpbin.org/post",data=payload)
>>> 

有没有参考的不同
>>> r.text
'{\n  "args": {}, \n  "data": "", \n  "files": {}, \n  "form": {}, \n  "headers": {\n    "Accept": "*/*", \n    "Accept-Encoding": "gzip, deflate, br", \n    "Content-Length": "0", \n    "Host": "httpbin.org", \n    "User-Agent": "python-requests/2.28.1", \n    "X-Amzn-Trace-Id": "Root=1-671b4668-1f54cdbc43c5b947731a92b5"\n  }, \n  "json": null, \n  "origin": "146.190.165.134", \n  "url": "https://httpbin.org/post"\n}\n'
>>> r1.text 
'{\n  "args": {}, \n  "data": "", \n  "files": {}, \n  "form": {\n    "key1": "value1", \n    "key2": "value2"\n  }, \n  "headers": {\n    "Accept": "*/*", \n    "Accept-Encoding": "gzip, deflate, br", \n    "Content-Length": "23", \n    "Content-Type": "application/x-www-form-urlencoded", \n    "Host": "httpbin.org", \n    "User-Agent": "python-requests/2.28.1", \n    "X-Amzn-Trace-Id": "Root=1-671b46b8-2b9d0e294d20bcc104da3fb3"\n  }, \n  "json": null, \n  "origin": "146.190.165.134", \n  "url": "https://httpbin.org/post"\n}\n'

In [18]: with open('/tmp/i.jpg','wb') as fobj:
    ...:     fobj.write(r2.content)

requests模块-发送带参数的请求

1. url 中直接带参数 2. 使用params 参数

返回值类型 

   r.content：返回的是响应内容的二进制形式，类型为 bytes。这意味着它可以包含任何类型的数据，比如图片、音频、视频等二进制文件，也可以是文本数据。
   r.text：返回的是响应内容的字符串形式，类型为 str。它会尝试根据响应的 Content-Type 头部信息或自动检测来对二进制数据进行解码。

2. 代码示例及区别展示

python

import requests

  1. 发送 HTTP 请求

r = requests.get('https://www.example.com')

  1. 使用 r.content 获取二进制响应内容

content = r.content print(type(content)) # 输出: <class 'bytes'>

  1. 使用 r.text 获取字符串响应内容

text = r.text print(type(text)) # 输出: <class 'str'>

请输入您想翻译的内容：你好
↓
get_postdata() 发送请求
↓
API 返回 JSON（字节流）
↓
run() 接收数据，并调用 parse_data()
↓
parse_data() 解析 JSON，提取 `out`
↓
输出翻译结果：Hello
