create_product.php

if (isset($_POST['nameproducts'])) {

$name = $_POST['nameproducts'];

require_once('database.php');

$chuoi_sql = "INSERT INTO products(name) VALUES('$name')";
$pdo->setQuery($chuoi_sql) ;
$result = $pdo->execute(array('$name'));

}

我想要实现的目标：在我的开发PC上运行从Android应用程序到Apache Web服务器的简单POST请求，并显示发送表单的PHP脚本的POSTed数据。所以，为什么我不能＆＃34; POST＆＃34;到服务器，我使用warpserver。服务器或我的Android客户端出错？为什么HTTPCLIENT.execute()无法运行。

Answer 1

CreateNewProduct的第24行，

HttpPost httppost = new HttpPost(http://localhost:8080/Ten_project/create_product.php);

当您将网址作为字符串传递时，您需要将网址包装在双引号内。

其次，localhost在您的Android模拟器中无法使用。您需要使用10.0.2.2代替localhost。所以您应该使用

HttpPost httppost = new HttpPost("http://10.0.2.2:8080/Ten_project/create_product.php");

在您的logcat中，如果您设置了无效的uri，则会看到IllegalArgumentException。

注意：如果10.0.2.2对您不起作用，您可以随时使用本地IP.Just不要使用localhost或127.0.0.1。

我不能＆＃34; POST＆＃34;从android服务器PHP
