Question

我正在尝试通过Google App Engine进行HTTPRequest发布。这就是我到目前为止所拥有的

URL url = new URL("http://myurl.com/myfile.php");
HTTPRequest request = new HTTPRequest(url, HTTPMethod.POST);
request.setPayload(########);
HTTPResponse response = URLFetchServiceFactory.getURLFetchService().fetch(request);

这里我需要设置一些配对值（即“email”，“hi @ example.com”等）由于setPayload接受byte []，我不知道如何转换我的配对值进入字节。

我搜索了其他帖子，但我很困难。

编辑：我已经改变了，但它仍然无法正常工作

byte[] data = ("EMAIL=bo0@gmail.com&amp;TITLE=evolution&amp;COMMENT=comments&amp;PRICE=5000;").getBytes();
try {
URL url = new URL("http://www.bo.x10.mx/nPost.php");
HTTPRequest request = new HTTPRequest(url, HTTPMethod.POST);
request.setPayload(data);
HTTPResponse response = URLFetchServiceFactory.getURLFetchService().fetch(request);

这是我在php网站上的内容。

<?php
include "path/conf.php"; //logging into database works
$tb_name = 'Post';
$EMAIL=$_POST['EMAIL'];
$TITLE =$_POST['TITLE'];
$COMMENT =$_POST['COMMENT'];
$PRICE =$_POST['PRICE'];
if(!isset($EMAIL) || !isset($TITLE ) || !isset($PRICE )|| !isset($COMMENT)){
header('HTTP/1.0 412 Precondition Failed', true, 412);
die('Bad data');
}
$sql="INSERT INTO $tb_name(EMAIL, TITLE, COMMENT, PRICE) VALUES ('$EMAIL', '$TITLE ', '$COMMENT ', '$PRICE ')";
$result=mysql_query($sql);
if($result==TRUE){
echo "successfully inserted into table!";}
else{
echo "error in inserting into table!";
header('HTTP/1.0 500 Internal Server Error', true, 500);}
ob_end_flush();
exit();
?>

EDIT2：这是一个有效的代码

try{
byte[] data = ("EMAIL=bo0@gmail.com&TITLE=evolution&COMMENT=comments&PRICE=5000").getBytes("UTF-8");
URL url = new URL("http://www.box.com/nost.php");
HTTPRequest request = new HTTPRequest(url, HTTPMethod.POST);
request.setPayload(data);
HTTPResponse response = URLFetchServiceFactory.getURLFetchService().fetch(request);
}

我的数据库字符串字段的类型为UTF-8

使用请求正文创建String，然后获取字节数组。例如，我们有：

URL url = new URL("http://myurl.com/myfile.php");
HTTPRequest request = new HTTPRequest(url, HTTPMethod.POST);
String body = "email=" + email + "&mpla=" + mpla;
request.setPayload(body.getBytes("UTF-8"));
HTTPResponse response = URLFetchServiceFactory.getURLFetchService().fetch(request);

希望这有帮助！

在谷歌应用引擎中使用HTTP请求设置Payload
