使用AppEngine发送具有相同名称的多个POST数据项 [英] Sending multiple POST data items with the same name, using AppEngine
问题描述
我尝试使用AppEngine中的urlfetch将POST数据发送到服务器。其中一些POST数据项具有相同的名称,但具有不同的值。
I try to send POST data to a server using urlfetch in AppEngine. Some of these POST-data items has the same name, but with different values.
form_fields = {
"data": "foo",
"data": "bar"
}
form_data = urllib.urlencode(form_fields)
result = urlfetch.fetch(url="http://www.foo.com/", payload=form_data, method=urlfetch.POST, headers={'Content-Type': 'application/x-www-form-urlencoded'})
但是,在本例中,服务器似乎只接收一个名为 data $ c的项$ c>,值为
bar
。如何解决这个问题?
However, in this example, the server seems to receieve only one item named data
, with the value bar
. How could I solve this problem?
推荐答案
修改您的 form_fields
字典将具有相同名称的字段转换为列表,并使用 doseq
参数指向 urllib.urlencode
:
Modify your form_fields
dictionary so that fields with the same name are turned into lists, and use the doseq
argument to urllib.urlencode
:
form_fields = {
"data": ["foo","bar"]
}
form_data = urllib.urlencode(form_fields, doseq=True)
此时, code> form_data 是'data = foo& data = bar'
,这是我认为您需要的。
At this point, form_data
is 'data=foo&data=bar'
, which is what I think you need.
