Question

我有一个简单的cli程序，它获取一个mac地址和机器名，创建一个包含此信息的post字符串，并尝试使用.net的WebBrowser.Naviate方法通过POST发送它。除了发送的POST数据外，一切似乎都在工作。每当我打印出PHP的Post数组的内容时，我得到一个空数组。我错过了某个地方的一步吗？

更新

我找到了apache的access.log文件并进行了一些实验。我找到了最初的POST请求：

"POST /test.php HTTP/1.1" 200 0 325 "-" "Mozilla/5.0 (Windows NT 6.1; WOW64; Trident/7.0; rv:11.0) like Gecko"

然后我从postData变量中删除了第二个get参数，以查看请求大小是否已更改，如下所示：

"POST /test.php HTTP/1.1" 200 0 296 "-" "Mozilla/5.0 (Windows NT 6.1; WOW64; Trident/7.0; rv:11.0) like Gecko"

所以我知道正在发出POST请求，并且POST数据包含在请求中。 apache解析字节数组会有问题吗？值得注意的是，每次发出POST请求时，都会立即发出额外的GET请求，之后我认为这很奇怪：

"POST /test.php HTTP/1.1" 200 0 325 "-" "Mozilla/5.0 (Windows NT 6.1; WOW64; Trident/7.0; rv:11.0) like Gecko"
"GET /test.php HTTP/1.1" 200 0 269 "-" "Mozilla/5.0 (Windows NT 6.1; WOW64; Trident/7.0; rv:11.0) like Gecko"

Answer 1

我认为你应该在?的开头丢失postData。

问号用于在GET请求中将路径与查询参数分开。

对于POST请求，特别是您正在使用的application/x-www-form-urlencoded，您只需传递URL编码的参数，形成key=value对，由&分隔。无需?。

另外，请尝试将最后一个参数更改为"Content-Type: application/x-www-form-urlencoded" + Environment.NewLine。

WebBrowser.Navigate将发布数据发送到PHP
