在PHP中处理嵌套的JSON POST请求

问题描述：

I am trying to have a python client send a post request which contains nested JSON like such

{"nested":{"field1":"response1", "field2":"response2"}}

My python code is here

from urllib.parse import urlencode
from urllib.request import Request, urlopen

url="http://localhost/api/vscore.php"
post_fields={"nested":{"field1":"response1", "field2":"response2"}}

request = Request(url, urlencode(post_fields).encode())
json = urlopen(request).read().decode()
print(json)

PHP code:

print_r($_POST["nested"]);

returns

{'field2': 'response2', 'field1': 'response1'}

but when I try to access "field1" with $_POST["nested"]["field1"], it returns this:

instead of returning "response1". How can I get my code to return fields in nested JSON?

我试图让python客户端发送一个包含嵌套JSON的帖子请求 p> {“nested”：{“field1”：“response1”，“field2”：“response2”}} code> pre>

我的python 代码在这里 p>


  from urllib.parse import urlencode 
 from urllib.request import Request，urlopen 
 
url =“http：  //localhost/api/vscore.php"
post_fields={"nested":{"field1":"response1“，”field2“：”response2“}} 
 
request = Request（url，urlencode（post_fields）。  encode（））
json = urlopen（request）.read（）。decode（）
print（json）
  code>  pre> 
 
  PHP代码： p> 
  
 
 的print_r（$ _ POST [ “嵌套”]）; 
 代码>  PRE> 
 
 返回 p> 
 
 
  {'field2'：'response2'，'field1'：'response1'} 
  code>  pre> 
 
 但当我尝试使用$ _POST [“嵌套”访问“field1”时 “] [”field1“]，它返回： p> 
 
 
  {
  code>  pre> 
 
 而不是返回”response1“  。 如何让我的代码返回嵌套JSON中的字段？ p> 
  div>

答

If request is in json form then, you should json_decode it first and then try to access. nested key should be accessed as:

$nested = json_decode($_POST["nested"], true);
$field = $nested["field1"];
