Php 本地主机(在自定义端口)在POST请求后返回空数据
我试图使用PHP从本地服务器Php 本地主机(在自定义端口)在POST请求后返回空数据,php,post,localhost,Php,Post,Localhost,我试图使用PHP从本地服务器localhost读取数据,但似乎没有返回任何数据。这是我的完整剧本 <?php $address = "localhost"; echo "Attempting to open the socket at ".$address."...\n"; $fp = fsockopen($address, 49801, $errno, $errstr, 10); echo "Error number is "; echo $errno; echo ".\
localhost
读取数据,但似乎没有返回任何数据。这是我的完整剧本
<?php
$address = "localhost";
echo "Attempting to open the socket at ".$address."...\n";
$fp = fsockopen($address, 49801, $errno, $errstr, 10);
echo "Error number is "; echo $errno; echo ".\n";
echo "Error string is ".$errstr.".\n";
echo "Attempt complete.\n";
if ($fp) {
print "Socket in now open.\n";
syslog(LOG_INFO, "socket.php: Reaching the specified address...");
print "Writing requests...\n"; //Hangs for about 1-2 minutes
fwrite($fp, "POST / HTTP/1.0\r\nUser-Agent: PHP XMLRPC 1.0\r\nHost: ".$address."Content-Type: text/xml\r\nContent-Length: ".strlen($payload)."\r\n\r\n");
$msg = "";
while($data = fread($fp, 32768)) {
$msg= $msg.$data;
}
if (strlen($msg) != 0) {
print "Final message: ***".$msg."***\n";
} else {
print "There is no data received from '".$address."'\n";
}
fclose($fp);
} else {
print "Error\n";
}
?>
如上面的脚本所述,最后一行Writing requests…
挂起约1或2分钟,然后追加一个空字符串
我认为这很奇怪,因为这个脚本在HTTP的端口80或SSH的端口22上运行良好。我限制了对localhost:49801
配置的访问,因此无法对服务器的配置进行任何更改
然而,我想知道服务器的配置是否有问题,这样我就不必再为下一天而烦恼了
顺便说一下,我正在CentOS 7上运行PHP5.4
编辑“Content Length:111”中的“111”是一个任意数字,它取决于有效负载的字符串长度
谢谢你的帮助 您的服务器没有回复,因为他正在等待您发送的111字节数据 如果您向服务器发送正确数量的数据,他将相应地作出响应 下面是我将内容长度更改为9的工作示例 然后我使用写入发送9位数据:
<?php
$address = "localhost";
$payload = "Some data";
echo "Attempting to open the socket at ".$address."...\n";
$fp = fsockopen($address, 49801, $errno, $errstr, 10);
echo "Error number is "; echo $errno; echo ".\n";
echo "Error string is ".$errstr.".\n";
echo "Attempt complete.\n";
if ($fp) {
print "Socket in now open.\n";
syslog(LOG_INFO, "socket.php: Reaching the specified address...");
print "Writing requests...\n";
fwrite($fp, "POST / HTTP/1.0\r\nUser-Agent: PHP XMLRPC 1.0\r\nHost: ".$address.
"\r\nContent-Type: text/xml\r\nContent-Length: ". strlen($payload) ."\r\n\r\n");
//We send the data to the server
fwrite($fp, $payload);
$msg = "";
while($data = fread($fp, 32768)) {
$msg= $msg.$data;
}
if (strlen($msg) != 0) {
print "Final message: ***".$msg."***\n";
} else {
print "There is no data received from '".$address."'\n";
}
fclose($fp);
} else {
print "Error\n";
}
?>
为什么不使用标准的HTTP方法而不是使用C套接字API?另外,您告诉HTTP服务器希望有111字节的正文,但不发送它。嗯,我不确定我是否理解您所说的“C套接字API”是什么意思,而且我忘了提到111只是一个任意数字,根据负载的不同而有所不同。我将更新帖子。如果您搜索如何从PHP发布HTTP,我可以向您保证,您的结果几乎不会涉及fsockopen()
。尝试使用curl,甚至只使用steamfile\u put\u contents()
。您的编辑不会改变您在标题后不发送任何内容。谢谢您的回答。我刚刚在终端中尝试了这段代码,但当运行实际的应用程序时(它有相同的代码,但在您的示例中不是像111或9这样的数字,而是strlen($payload),它总是不同于0),它不是:D。您认为服务器是否期望一定大小的数据,只是没有响应?如果是这样的话,您是否认为有可能找到一种读取服务器期望的数据大小的方法?谢天谢地,我的大脑非常慢,我知道strlen(“一些数据”)=9,所以是的。。。但我觉得很奇怪,它与strlen($payload)不起作用,这正是我在之前的评论中所说的。我认为问题出在服务器端。如果是的话,我会接受你的回答。我只是改变我的回答以反映你的评论。当我尝试它时,它起作用了,所以我真的不明白你的问题是什么。你能告诉我上面的例子是否适合你吗?如果没有,我将需要与您正在处理的代码完全相同的代码来查看问题所在。是的,谢谢,我忘了说代码在终端上工作正常,但在实际应用程序上没有,但应用程序由于Python问题而挂起-_-
