Php 如何使用Python将键值对和二进制信息一起发送到服务器

这个过程是我向服务器发送一个票证，服务器将响应我需要的信息。比如说,

import requests
URL = "https://ssl.XXX.com/sql_v5i.php"
Ticket = {"A":"1","B":"2"}  # a dictionary
ticket_post = requests.post(URL, data=Ticket)
print ticket__post.text

但是如何同时发送带有

“A”：“1”、“B”：“2”

和二进制数据（只有数据，没有密钥）的票据

要完成此任务，有以下几项php工作：

<?php

$BASE_SERVER_URL="https://ssl.XXX.com/sql_v5i.php"
$TICKET = array(
          'fn' => 'ticket',
          'testid' => '2'
          ... # And many other key-value pair in the TICKET array
          );    

class DataStreamer{
  private $data;
  private $pos;

function __construct($data) {
  $this->data = $data;
  $this->pos = 0;
}

function stream_function($handle, $fd, $count){
$res = substr($this->data, $this->pos, $count);
$this->pos += strlen($res);
return $res;
}
}

function sendTicketToServer($data) {
global $TICKET, $BASE_SERVER_URL; # TICKET is an array stores ticket           
                                  #  information in php
$ret = array(true);  
$postFields = "";
foreach ($TICKET as $name => $val)
    $postFields = (empty($postFields) ? "" :  "${postFields}&") ."${name}=" . urlencode($val); 

$ch = curl_init(); 

curl_setopt( $ch, CURLOPT_POST, true );  
curl_setopt( $ch, CURLOPT_URL, "${BASE_SERVER_URL}?" . $postFields );  
                                        # add key-value pairs
curl_setopt( $ch, CURLOPT_VERBOSE, false );
curl_setopt( $ch, CURLOPT_RETURNTRANSFER, true );
curl_setopt( $ch, CURLOPT_SSL_VERIFYPEER, FALSE );
curl_setopt( $ch, CURLOPT_SSL_VERIFYHOST, FALSE );

 if (!empty($data)) { # data is the binary string , add binary string
    curl_setopt( $ch, CURLOPT_BINARYTRANSFER, true); 
    curl_setopt( $ch, CURLOPT_HEADER, true); 
    curl_setopt( $ch, CURLOPT_HTTPHEADER, array('Content-type: application/octet-stream', 'Content-length: ' . strlen($data))); 
    curl_setopt( $ch, CURLOPT_READFUNCTION, array(new DataStreamer($data), "stream_function")); 
    } else {
    curl_setopt( $ch, CURLOPT_HTTPHEADER, array('Content-type: application/octet-stream', 'Content-length: 0')); 
}

$resp = curl_exec($ch);
$code=curl_getinfo($ch, CURLINFO_HTTP_CODE);
if( $resp === FALSE || $code !== 200 ) {
    echo "!!!!! Failed to get connection from the server. Code:    $code\n";
    return array(ERR_NO_SERVER_CONNECTION."000");
}

curl_close($ch); 
return $ret;

PHP
示例不以
POST
数据的形式发送
Ticket
，而是以
GET
数据的形式发送-它的意思是在url中

https://ssl.XXX.com/sql_v5i.php?A=1&B=2

您可以使用
params=Ticket
在
请求中执行相同操作。然后可以使用
data=
或
files=
发送二进制数据

我使用特殊的门户来测试请求，但您的门户可能需要更多的工作

import requests

url = "http://httpbin.org/post"
ticket = {"A":"1","B":"2"}
binary_data = b'hello world'

headers = {
    'Content-type': 'application/octet-stream',
}

r = requests.post(url, params=ticket, data=binary_data, headers=headers)

print('--- requests ---')
print(r.url)
print(r.request.headers)
print(r.request.body)

print('--- response ---')
print(r.text)

结果:

--- requests ---
http://httpbin.org/post?B=2&A=1
{'Content-type': 'application/octet-stream', 'Accept-Encoding': 'gzip, deflate', 'Content-Length': '11', 'User-Agent': 'python-requests/2.12.1', 'Connection': 'keep-alive', 'Accept': '*/*'}
b'hello world'
--- response ---
{
  "args": {
    "A": "1", 
    "B": "2"
  }, 
  "data": "hello world", 
  "files": {}, 
  "form": {}, 
  "headers": {
    "Accept": "*/*", 
    "Accept-Encoding": "gzip, deflate", 
    "Content-Length": "11", 
    "Content-Type": "application/octet-stream", 
    "Host": "httpbin.org", 
    "User-Agent": "python-requests/2.12.1"
  }, 
  "json": null, 
  "origin": "xxx.xxx.xxx.xxx", 
  "url": "http://httpbin.org/post?B=2&A=1"
}


您还可以使用本地代理服务器（ie）来比较PHP请求和Python请求

PHP:

Python:

proxy = {
    'http': '127.0.0.1:8888',
    'https': '127.0.0.1:8888',
}

r = requests.post(url, params=ticket, data=binary_data, 
                    headers=headers, proxies=proxy)

Pyghon是某种类型的库吗？
PHP
不发送
票证
作为POST数据，而是在url中-请参见
“${BASE\u SERVER\u url}？”$postFields
-因此它使用url
https://ssl.XXX.com/sql_v5i.php?A=1&B=2
。您可以在
requests
中使用
params=Ticket
执行相同的操作。然后你可以让我们
data=
发送二进制数据。谢谢。这很有帮助。在这个例子中，binary_data=b'hello world'。但在我的例子中，二进制_数据=”����5UU��ǚ���������H�v�������������������........������������������������������"  （太长了，无法全部放在注释部分）。当我运行代码时，在文件的第X行（二进制字符串行）显示“SyntaxError:非ASCII字符'\xef'，但没有声明编码；有关详细信息，请参阅。如何将此“二进制数据”发送到服务器？
proxy = {
    'http': '127.0.0.1:8888',
    'https': '127.0.0.1:8888',
}

r = requests.post(url, params=ticket, data=binary_data, 
                    headers=headers, proxies=proxy)
