问题描述
在PHP中构建一个HTTP POST查询我可以用一个叫做简单的方法：http_build_query将返回基于传递给函数在阵列上以下内容：
简单数组：
阵列
（
[0] =＆GT;富
[1] =＆GT;酒吧
[2] =＆GT;巴兹
[3] =＆GT;繁荣
[牛] =＆GT;牛奶
[PHP] =＆GT;超文本处理器
）
返回：
<$p$p><$c$c>flags_0=foo&flags_1=bar&flags_2=baz&flags_3=boom&cow=milk&php=hypertext+processor有点更复杂的数组：
阵列
（
[用户] =＆GT;排列
（
[名] =＆GT;鲍勃·史密斯
[年龄] =＆GT; 47
[性爱] =＆GT;中号
[DOB] =＆GT; 1956年5月12日
）[消遣] =＆GT;排列
（
[0] =＆GT;高尔夫球
[1] =＆GT;歌剧
[2] =＆GT;扑克
[3] =＆GT;敲击
）[儿童] =＆GT;排列
（
[鲍比] =＆GT;排列
（
[年龄] =＆GT; 12
[性爱] =＆GT;中号
） [出击] =＆GT;排列
（
[年龄] =＆GT; 8
[性爱] =＆GT; F
） ）[0] =＆GT; CEO
）
返回：
<$p$p><$c$c>user%5Bname%5D=Bob+Smith&user%5Bage%5D=47&user%5Bsex%5D=M&user%5Bdob%5D=5%2F12%2F1956&pastimes%5B0%5D=golf&pastimes%5B1%5D=opera&pastimes%5B2%5D=poker&pastimes%5B3%5D=rap&children%5Bbobby%5D%5Bage%5D=12&children%5Bbobby%5D%5Bsex%5D=M&children%5Bsally%5D%5Bage%5D=8&children%5Bsally%5D%5Bsex%5D=F&flags_0=CEO什么我问的是，有没有什么办法来创建的Java / Android的后者实体格式？我已尝试以下没有任何运气：
列表＆LT;＆的NameValuePair GT; namevaluepairs中=新的ArrayList＆LT;＆的NameValuePair GT;（3）;
nameValuePairs.add（新BasicNameValuePair（用户，NULL））;
nameValuePairs.add（新BasicNameValuePair（名字，管理员））;
nameValuePairs.add（新BasicNameValuePair（姓氏，管理员））;
httppost.setEntity（新UrlEn codedFormEntity（namevaluepairs中））;
希望有人知道如何做到这一点:)
亲切的问候，

编辑：
基本上我需要的是产品在Java中对应的PHP的：
$ PARAMS =阵列（'用户'=＆GT;阵列（
'名字'=＆GT; 鲍勃·史密斯，
'姓氏'=＆GT; 强生
））;
这是JSON格式相同的请求：
{用户：{名字：鲍勃·史密斯，姓氏：强生}}
我只需要在Java相当于应用程序/ x-WWW的形式urlen codeD格式）
BTW。非常感谢回答须藤code，真的appriciate它！
我知道了。这里的样本code：
字符串数据= EntityUtils.toString（新UrlEn codedFormEntity（namevaluepairs中，UTF-8））;
数据=放大器; + data.replaceAll（％5B0％5D，[0]）;
StringEntity本身=新StringEntity（数据，UTF-8）;
se.setContentType（应用程序/ x-WWW的形式urlen codeD）;
se.setContentEncoding（UTF-8）;
httppost.setEntity（SE）;
一个有点讨厌，但它的工作。您可能想要得到它更通用的一点 - 这是只有1个元素的数组
When building a HTTP POST Query in PHP I can use a simple method called: http_build_query which will return the following based on the array passed to function:
Simple array:
Array
(
[0] => foo
[1] => bar
[2] => baz
[3] => boom
[cow] => milk
[php] => hypertext processor
)
Returns:
flags_0=foo&flags_1=bar&flags_2=baz&flags_3=boom&cow=milk&php=hypertext+processor
A Bit more complex array:
Array
(
[user] => Array
(
[name] => Bob Smith
[age] => 47
[sex] => M
[dob] => 5/12/1956
)
[pastimes] => Array
(
[0] => golf
[1] => opera
[2] => poker
[3] => rap
)
[children] => Array
(
[bobby] => Array
(
[age] => 12
[sex] => M
)
[sally] => Array
(
[age] => 8
[sex] => F
)
)
[0] => CEO
)
Returns:
user%5Bname%5D=Bob+Smith&user%5Bage%5D=47&user%5Bsex%5D=M&user%5Bdob%5D=5%2F12%2F1956&pastimes%5B0%5D=golf&pastimes%5B1%5D=opera&pastimes%5B2%5D=poker&pastimes%5B3%5D=rap&children%5Bbobby%5D%5Bage%5D=12&children%5Bbobby%5D%5Bsex%5D=M&children%5Bsally%5D%5Bage%5D=8&children%5Bsally%5D%5Bsex%5D=F&flags_0=CEO
What I'm asking is, is there any way to create the latter entity format in Java/Android? I've tried the following without any luck:
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(3);
nameValuePairs.add(new BasicNameValuePair("user", null));
nameValuePairs.add(new BasicNameValuePair("firstname", "admin"));
nameValuePairs.add(new BasicNameValuePair("lastname", "admin"));
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
Hopefully someone know how to achieve this :)Kind regards,Morten
EDIT:
Basically what i need is to to product the Java equivalent of this PHP:
$params = array('user' => array(
'firstname' => 'Bob Smith',
'lastname' => 'Johnson'
));
And this is the same request in JSON format:
{"user":{"firstname":"Bob Smith","lastname":"Johnson"}}
I just need the Java equivalent in application/x-www-form-urlencoded format ;)
BTW. Thanks alot for answering sudocode, really appriciate it!
I've got it. Here's the sample code:
String data = EntityUtils.toString(new UrlEncodedFormEntity(nameValuePairs,"UTF-8"));
data = "&" + data.replaceAll("%5B0%5D", "[0]");
StringEntity se = new StringEntity(data, "UTF-8");
se.setContentType("application/x-www-form-urlencoded");
se.setContentEncoding("UTF-8");
httppost.setEntity(se);
A bit nasty, but it's working. You may want to get it a bit more generic - this is for 1-element array only.
