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'
