从iOS发送多部分POST并读取PHP$\u POST中的参数?

从iOS发送多部分POST并读取PHP$\u POST中的参数?,php,objective-c,ios,post,nsurlrequest,Php,Objective C,Ios,Post,Nsurlrequest,我试图将一篇多行文章从iPhone/iPad发送到php服务,问题是出于某种原因,文章内容类型似乎是application/x-www-form-urlengond,(我是通过Wireshark发现的) 这实际上是Wireshark POST数据包捕获的一个片段: **Content-Type: application/x-www-form-urlencoded\r\n** Content-Length: 324\r\n [Content length: 324]

我试图将一篇多行文章从iPhone/iPad发送到php服务,问题是出于某种原因,文章内容类型似乎是application/x-www-form-urlengond,(我是通过Wireshark发现的)

这实际上是Wireshark POST数据包捕获的一个片段:

    **Content-Type: application/x-www-form-urlencoded\r\n**
    Content-Length: 324\r\n
        [Content length: 324]
    Connection: keep-alive\r\n
    \r\n
    [Full request URI: http://my.server.com/mobile/tools/authentication]
Line-based text data: application/x-www-form-urlencoded
    --0xKhTmLbOuNdArY\r\n
    Content-Disposition: form-data; name="login"\r\n
    \r\n
    hello@hello.com\r\n
    --0xKhTmLbOuNdArY\r\n
    Content-Disposition: form-data; name="password"\r\n
    \r\n
    somepassword\r\n
    --0xKhTmLbOuNdArY\r\n
    \r\n
    --0xKhTmLbOuNdArY--\r\n
<FORM action="http://my.server.com/mobile/tools/authentication.php" method="post">
   <P>
   <LABEL for="login">E-mail: </LABEL>
             <INPUT type="text" name="login"><BR>
   <LABEL for="password">pass: </LABEL>
             <INPUT type="text" name="password"><BR>
   <INPUT type="submit" value="Send"> <INPUT type="reset">
   </P>
</FORM>
    [myMedRequest addValue:[NSString stringWithFormat:@"multipart/form-data; boundary=%@\r\n", POSTBoundary] forHTTPHeaderField:@"Content-Type"];
问题是,在服务器中,我试图从这个POST请求中读取登录名和密码变量,但这是不可能的,因为我认为php认为POST请求是
x-www-form-urlencoded
,因此如果我设置
authentication.php
来执行:

<?php
echo("<pre>")
print_r($_POST)
echo("</pre>")
?>
以及从
authentication.php中的
print\r($\u POST)
输出的文本

如你所见,一开始我是这样做的:

但是在以前的Wireshark跟踪日志中,POST数据包被视为内容类型:application/x-www-form-urlencoded,也许我做了其他错误的事情

谢谢:)


编辑:我想避免像ASIHTTPRequest这样的外部框架,顺便说一句,ASIHTTPRequest开发已经被首席开发人员放弃了,如前所述

好的,因为没有外部库我找不到解决方案,我修复了我的代码和它,以防有人想使用它

我发布的代码上的问题是\r\n行上的错误

把它拆了,一切都好了


希望这对其他人有所帮助:)

我能想到的唯一一件事是:为什么要手动编写http请求?这不是API的作用吗?NSMutableURLRequest是提供的“API”,有一些框架可以做到这一点,但我试图避免使用外部框架。更新。如何支持放置/删除/修补程序。:)谢谢我只是想试试。它能处理嵌套字典吗?我正在尝试发布一个图像,其中包括根级别的“条目”字典,然后是嵌套级别的描述、日志id和图片。不要这样认为,您可能会在Github上打开一个问题:)
