使用POST將文件從Python腳本發送到PHP腳本

Question

import urllib,MultipartPostHandler,urllib2,cookielib
cookies = cookielib.CookieJar()
opener =     urllib2.build_opener(urllib2.HTTPCookieProcessor(cookies),MultipartPostHandler.MultipartPostHandler)
urllib2.install_opener(opener)
login = urllib.urlencode(dict(admin_user='admin',admin_pass='****'))
o=opener.open('http://some_domain_name/admin/index.php',login)
print o.read()

在上述代碼的幫助下，我能夠登錄到管理面板。 我應該在這里發布一些廣告（在這里，我要自動執行任務和涉及廣告標題，廣告描述以及主要是一系列圖像的字段（我想圖像列表是一個更好的名詞；））

HTML代碼段：

<form action="postad.php?cityid=15&subcatid=1" method="post" name="frmPost" enctype="multipart/form-data" 

 <!-- Some other code -->


<td><input name="showemail" type="radio" value="1" >&nbsp;</td>
<table class="postad" cellspacing="0" cellpadding="0" border="0" width="100%">

<tr>
    <td><b>Upload Pictures:</b><br>
    <span class="hint">Maximum filesize: 300KB</span><br>
                <input type="file" name="pic[]" size="69"><br>
        <img src="images/spacer.gif" height="2"><br>
                <input type="file" name="pic[]" size="69"><br>
        <img src="images/spacer.gif" height="2"><br>
                <input type="file" name="pic[]" size="69"><br>
        <img src="images/spacer.gif" height="2"><br>
                <input type="file" name="pic[]" size="69"><br>
        <img src="images/spacer.gif" height="2"><br>
                <input type="file" name="pic[]" size="69"><br>
        <img src="images/spacer.gif" height="2"><br>
            </td>
</tr>

</table>


<!-- some other code -->
<input name="do" type="hidden" id="do" value="post">
<button type="submit">Post Now</button>

所以解決這個問題，我使用的是這段代碼，但是每次我都無法附加圖像時。 你們能在這方面幫助我嗎？

raw_params={"adtitle":"sample title",
        "area":"sample area",
        "addesc":"<p>sample post</p>",
        "price":"2000",
        "x[1]":"2012",
        "email":"abc@def.com",
        "showemail":"2",
        "subcatid":"15",
    "do":"post",
        }

encoded_params=urllib.urlencode(raw_params)
target_page = 'http://some_domain_name/admin/postad.php?cityid=15&subcatid=15'
opener.open(target_page,encoded_params)

我忘了告訴你一件事，這是我從LIVEHTTPHeader（mozilla-plugin）獲得的日志

Content-Disposition: form-data; name="adtitle"

sample title

並請對此進行一些說明：filename =“ 3_d_flower.jpg

Answer 1

我絕對會為此推薦requests庫。 它使多部分POST 更加簡單 。 它還可以更簡單地處理Cookie 。

登錄代碼在請求中如下所示：

import requests
o = requests.get('http://some_domain_name/admin/index.php', 
                 data={admin_user: 'admin',
                       admin_pass: '****'})
print o.text
print o.cookies

Answer 2

import urllib,MultipartPostHandler,urllib2,cookielib

cookies = cookielib.CookieJar()
opener = urllib2.build_opener(urllib2.HTTPCookieProcessor(cookies),MultipartPostHandler.MultipartPostHandler)
urllib2.install_opener(opener)
login = urllib.urlencode(dict(admin_user='admin',admin_pass='****'))
o=opener.open('http://some_domain_name.com/admin/index.php',login)
print o.read()
