python requests post多层字典的方法
pyhton requests模块post方法传参为多层字典时,转换错误,
如,表单传参
{ “a”:1, “b”:{ “A”:2, “B”:3 } }
post请求后看到form data是:
a:1 b:A b:B
查看官方文档:
More complicated POST requests
Typically, you want to send some form-encoded data — much like an HTML form. To do this, simply pass a dictionary to the data argument. Your dictionary of data will automatically be form-encoded when the request is made:
payload = {‘key1': ‘value1', ‘key2': ‘value2'} r = requests.post(“http://httpbin.org/post“, data=payload) print(r.text) { … “form”: { “key2”: “value2”, “key1”: “value1” }, … }
这里说post传入的dict类型参数会被自动转化为form-encoded,查看请求后,这里的demo是一个一层的字典。多层字典传输的时候,确实会异常。
解决办法:
将第二层字典转化为json,json.dumps({“A”:2,”B”:3}),然后赋给b。
以上这篇python requests post多层字典的方法就是小编分享给大家的全部内容了,希望能给大家一个参考,也希望大家多多支持【听图阁-专注于Python设计】。
