在我的项目中,我需要将图像和字符串传输到服务器(服务器端使用php)。我完成了上传图片到服务器。唯一的问题是如何将字符串发送到服务器。有人能告诉我怎么做吗?
这里有一些代码可以为您指明正确的方向。
首先,在应用程序端使用如下代码:
Java:// generate your params:
String yourString = "This is the string you want to send";
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
nameValuePairs.add(new BasicNameValuePair("your_string", yourString));
// send them on their way
try {
DefaultHttpClient httpClient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost("http://xyz/your_php_script.php");
httpPost.setEntity(new UrlEncodedFormEntity(nameValueParams));
HttpResponse httpResponse = httpClient.execute(httpPost);
HttpEntity httpEntity = httpResponse.getEntity();
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
然后在你的服务器端(http://xyz/your_php_script.php):
)PHP:<?php
if (isset($_POST['your_string']) && $_POST['your_string'] != '') {
$your_string = $_POST['your_string'];
echo 'received the string: ' . $your_string;
} else {
echo 'empty';
}
?>
编辑,根据你的评论:
它更复杂,因为你必须使用OutputStream
和BufferedWriter
,所以我不知道为什么我的解决方案对你不起作用。通过谷歌,我找到了以下可能对你有帮助的答案:
