[英]json Data with POST requests in Python doesn't arrive
I like to build a small REST Interface to connect PYTHON with PHP. 我喜欢构建一个小的REST接口以将PYTHON与PHP连接。 After some hours of google I ended with nearly copy&paste code from several discussion-boards:
Google几个小时后,我从几个讨论区中几乎复制并粘贴了代码:
import requests
import json
url = 'http://spidercontrol.ilumiweb.local/helge/voltage'
headers = {'Content-type': 'application/json', 'Accept': 'text/plain'}
data = {'value': '7.4', 'decay_time': '300'}
r = requests.post(url, data=json.dumps(data), headers=headers)
This should send the data as json via POST to the given url.This is where it's sended to: 这应该通过POST将数据作为json发送到给定的url。这是发送到的位置:
<?php
echo "Method: \t".$_SERVER['REQUEST_METHOD']."\r\n";
print_r(getallheaders());
echo "Post:";
print_r($_POST);
echo "Get:";
print_r($_GET);
exit;
?>
But there is nothing in the $_POST data: 但是$ _POST数据中没有任何内容:
Method: POST
Array
(
[Host] => spidercontrol.ilumiweb.local
[Content-Length] => 37
[Content-type] => application/json
[Accept-Encoding] => gzip, deflate, compress
[Accept] => text/plain
[User-Agent] => python-requests/2.2.1 CPython/2.7.6 Windows/7
)
Post:Array
(
)
Get:Array
(
)
If I use the same code, but remove the headers=headers information but data=data it works well. 如果我使用相同的代码,但删除headers = headers信息,但删除data = data则效果很好。 Did someone know why?
有人知道为什么吗?
In PHP $_POST
only contains form data ( application/x-www-form-urlencoded
or multipart/form-data
encoded POST bodies). 在PHP中,
$_POST
仅包含表单数据( application/x-www-form-urlencoded
或multipart/form-data
编码的POST正文)。
To get JSON data you'll need to read the request body directly using php://input
instead: 要获取JSON数据,您需要直接使用
php://input
来读取请求正文:
$json = json_decode(file_get_contents("php://input"));
