我有一个带有 http GET 请求的 android 客户端,它在服务器上调用一个 php 脚本。我的服务器上有一个 php 脚本,它查询数据库并回显结果行。现在,我如何将 blob 文件和其他字段从响应??我觉得php代码搞砸了..如果你指出我正确的方向会很有帮助..谢谢!
My android code:
HttpClient httpClient = new DefaultHttpClient();
StringBuilder uriBuilder = new StringBuilder("http://192.168.x.x/file_download.php");
HttpGet request = new HttpGet(uriBuilder.toString());
HttpResponse response = httpClient.execute(request);
int status = response.getStatusLine().getStatusCode();
Log.i("Http Get",response.getStatusLine().toString());
// we assume that the response body contains the error message
if (status != HttpStatus.SC_OK) {
ByteArrayOutputStream ostream = new ByteArrayOutputStream();
response.getEntity().writeTo(ostream);
Log.e("HTTP CLIENT", ostream.toString());
} else {
// InputStream content = response.getEntity().getContent();
// <consume response>
String type = response.getEntity().toString();
content.close(); // this will also close the connection
}
我的PHP代码:
<?php
$conn = mysql_connect("localhost", "root", "root");
if (!$conn) {
echo "Unable to connect to DB: " . mysql_error();
exit;
}
if (!mysql_select_db("MYDB")) {
echo "Unable to select mydbname: " . mysql_error();
exit;
}
$sql = "SELECT title, filetype, mode, data, time, application, entity_id
FROM table
WHERE id=(select max(id) from file)";
$result = mysql_query($sql);
if (!$result) {
echo "Could not successfully run query ($sql) from DB: " . mysql_error();
exit;
}
if (mysql_num_rows($result) == 0) {
echo "No rows found, nothing to print so am exiting";
exit;
}
$rows = array();
while ($row = mysql_fetch_array($result, MYSQL_NUM)) {
$rows[]=$row;
}
echo $rows;
mysql_free_result($result);
?>
