使用Python爬虫库requests发送表单数据和JSON数据
导入Python爬虫库Requests
importrequests
一、发送表单数据
要发送表单数据,只需要将一个字典传递给参数data
payload={'key1':'value1','key2':'value2'} r=requests.post("http://httpbin.org/post",data=payload) print(r.text)
{"args":{},"data":"","files":{},"form":{"key1":"value1","key2":"value2"},"headers":{"Accept":"*/*","Accept-Encoding":"gzip,deflate","Connection":"close","Content-Length":"23","Content-Type":"application/x-www-form-urlencoded","Host":"httpbin.org","User-Agent":"python-requests/2.14.2"},"json":null,"origin":"110.18.198.88","url":"http://httpbin.org/post"}
也可以将一个元组列表传递给参数data,这样可以实现多个value对应一个key的情况(字典的key必须唯一)
payload=(('key1','value1'),('key1','value2')) r=requests.post('http://httpbin.org/post',data=payload) print(r.text)
{"args":{},"data":"","files":{},"form":{"key1":["value1","value2"]},"headers":{"Accept":"*/*","Accept-Encoding":"gzip,deflate","Connection":"close","Content-Length":"23","Content-Type":"application/x-www-form-urlencoded","Host":"httpbin.org","User-Agent":"python-requests/2.14.2"},"json":null,"origin":"110.18.198.88","url":"http://httpbin.org/post"}
二、发送字符串(JSON)数据
将json字符串传递给参数data
importjson url='https://api.github.com/some/endpoint' payload={'some':'data'} r=requests.post(url,data=json.dumps(payload))
将字典传递给参数json
url='https://api.github.com/some/endpoint' payload={'some':'data'} r=requests.post(url,json=payload)
