blocks|key|277535|text|例如，获取张贴的json字符串的最简单方法是读取'php://input‘的内容，然后对其进行解码。例如，我有一个简单的Zend路由：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|277536|'save-json'+=>+array(
'type'+=>+'Zend\Mvc\Router\Http\Segment',
++++++++++++'options'+=>+array(
++++++++++++++++'route'++++=>+'/save-json/',
++++++++++++++++'defaults'+=>+array(
++++++++++++++++++++'controller'+=>+'CDB\Controller\Index',
++++++++++++++++++++'action'+++++=>+'save-json',
++++++++++++++++),
++++++++++++),
++++++++),|code-block|syntax|javascript|277537|我想用Angular的$http.post向它发布数据。这篇文章很好，但Zend中的检索方法|277538|$this->params()->fromPost('paramname');+|277539|在这个案子里我什么都没拿到。所以我的解决方案是，在尝试了像$_POST和上面提到的其他方法之后，从“php://”中读取：|277540|$content+=+file_get_contents('php://input');
print_r(json_decode($content));|277541|我最终得到了我的json数组。希望这能有所帮助。|277542|entityMap^0|0|0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|S|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|T|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|U|8|@]|9|@]|A|$]]|$1|I|3|J|5|D|7|V|8|@]|9|@]|A|$E|F]]|$1|K|3|L|5|6|7|W|8|@]|9|@]|A|$]]|$1|M|3|N|5|D|7|X|8|@]|9|@]|A|$E|F]]|$1|O|3|P|5|6|7|Y|8|@]|9|@]|A|$]]|$1|Q|3|-4|5|6|7|Z|8|@]|9|@]|A|$]]]|R|$]]

The easisest way to get a posted json string, for example, is to read the contents of 'php://input' and then decode it. For example i had a simple Zend route:

<pre><code>'save-json' =&gt; array(
'type' =&gt; 'Zend\Mvc\Router\Http\Segment',
 'options' =&gt; array(
 'route' =&gt; '/save-json/',
 'defaults' =&gt; array(
 'controller' =&gt; 'CDB\Controller\Index',
 'action' =&gt; 'save-json',
 ),
 ),
 ),
</code></pre>

and i wanted to post data to it using Angular's $http.post. The post was fine but the retrive method in Zend 

<pre><code>$this-&gt;params()-&gt;fromPost('paramname'); 
</code></pre>

didn't get anything in this case. So my solution was, after trying all kinds of methods like $_POST and the other methods stated above, to read from 'php://':

<pre><code>$content = file_get_contents('php://input');
print_r(json_decode($content));
</code></pre>

I got my json array in the end. 
Hope this helps.

blocks|key|494435|text|如果您无法访问插件，例如在控制器之外，您可以从servicelocator获取参数，如下所示|type|unstyled|depth|inlineStyleRanges|entityRanges|data|494436|//from+POST
$foo+=+$this->serviceLocator->get('request')->getPost('foo');+
//from+GET
$foo+=+$this->serviceLocator->get('request')->getQuery()->foo;
//from+route
$foo+=+$this->serviceLocator->get('application')->getMvcEvent()->getRouteMatch()->getParam('foo');|code-block|syntax|javascript|494437|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

If You have no access to plugin for instance outside of controller You can get params from servicelocator like this

<pre><code>//from POST
$foo = $this-&gt;serviceLocator-&gt;get('request')-&gt;getPost('foo'); 
//from GET
$foo = $this-&gt;serviceLocator-&gt;get('request')-&gt;getQuery()-&gt;foo;
//from route
$foo = $this-&gt;serviceLocator-&gt;get('application')-&gt;getMvcEvent()-&gt;getRouteMatch()-&gt;getParam('foo');
</code></pre>

blocks|key|494466|text|如果你的内容类型是"application/-www-form-urlencoded“，上面的所有方法都可以很好地工作。但是，如果您的内容类型是"application/json“，那么您必须执行以下操作：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|494467|$params+=+json_decode(file_get_contents('php://input')，true)；print_r($params)；|494468|原因:参见https://www.toptal.com/php/10-most-common-mistakes-php-programmers-make中的#7|offset|length|494469|entityMap|0|LINK|mutability|MUTABLE|url|https://www.toptal.com/php/10-most-common-mistakes-php-programmers-make^0|0|0|5|1Z|0|0^^$0|@$1|2|3|4|5|6|7|P|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|Q|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|R|8|@]|9|@$F|S|G|T|1|U]]|A|$]]|$1|H|3|-4|5|6|7|V|8|@]|9|@]|A|$]]]|I|$J|$5|K|L|M|A|$N|O]]]]

All the above methods will work fine if your content-type is "application/-www-form-urlencoded".
But if your content-type is "application/json" then you will have to do the following:

$params = json_decode(file_get_contents('php://input'), true);
print_r($params);
