php url查询嵌套数组没有索引 [英] php url query nested array with no index

问题描述

我正在使用第三方API，它接收几个必须编码的参数，如下所示：

  text [] =你好％20World&安培;文本[] =％如何％20顷&20you放大器; HTML [] =< p为H.仅有％20fine，％20thank％20you< / p为H. 
  

正如你所看到的，这个API可以接受多个文本参数，也可以接受HTML（不在示例调用）。

我已经使用http_build_query为其他API正确构建了一个查询字符串

  $ params ['text'] [] ='Hello World'; 
 $ params ['text'] [] ='你好吗？'; 
 $ params ['html'] [] ='< p>很好，谢谢< / p>'; 
 
 $ http_query = http_build_query（$ params）; 
  

这种方法的问题在于它会用数字索引构建一个查询字符串：

text [0] = Hello％20World& text [1] =％20如何％20you？& html [0] =< p> Just ％20fine，％20thank％20you< / p>

不幸的是，我正在使用的API不喜欢数字索引， 。

是否有任何php函数/类方法可以帮助我快速构建查询？

谢谢

解决方案

似乎没有办法通过 http_build_query 。抱歉。在文档页面上，有人有这样的：

$ p $ function cr_post（$ a，$ b = 0，$ c = 0） {
if（！is_array（$ a））return false;
foreach（（array）$ a as $ k => $ v）{
if（$ c）$ k = $ b。[]; elseif（is_int（$ k））$ k = $ b。$ k;
if（is_array（$ v）|| is_object（$ v））{
$ r [] = cr_post（$ v，$ k，1）; continue;
}
$ r [] = urlencode（$ k）。=.urlencode（$ v）;
}
return implode（&，$ r）;
}


$ params ['text'] [] ='Hello World';
$ params ['text'] [] ='你好吗？';
$ params ['html'] [] ='< p>很好，谢谢< / p>';

$ str = cr_post（$ params）;
echo $ str;


我没有测试过它。如果它不起作用，那么你将不得不推出自己的。也许你可以发布github的要点，以便其他人可以使用它！

I'm working with a third party API that receives several parameters which must be encoded like this:

text[]=Hello%20World&text[]=How%20are%20you?&html[]=<p>Just%20fine,%20thank%20you</p>

As you can see this API can accept multiple parameters for text, and also for HTML (not in the sample call).

I have used http_build_query to correctly build a query string for other APIs

$params['text'][] = 'Hello World';
$params['text'][] = 'How are you?';
$params['html'][] = '<p>Just fine, thank you</p>';

$http_query = http_build_query($params);

The problem with this approach is that it will build a query string with the numeric index:

text[0]=Hello%20World&text[1]=How%20are%20you?&html[0]=<p>Just%20fine,%20thank%20you</p>

unfortunately the API I'm working with doesn't like the numeric index and fails.

Is there any php function/class-method that can help me build a query like this quickly?

Thank you

解决方案

There doesn't seem to be a way to do this with http_build_query. Sorry. On the docs page though, someone has this:

function cr_post($a,$b=0,$c=0){
    if (!is_array($a)) return false;
    foreach ((array)$a as $k=>$v){
        if ($c) $k=$b."[]"; elseif (is_int($k)) $k=$b.$k;
        if (is_array($v)||is_object($v)) {
            $r[]=cr_post($v,$k,1);continue;
        }
        $r[]=urlencode($k)."=" .urlencode($v);    
    }
    return implode("&",$r);
}


$params['text'][] = 'Hello World';
$params['text'][] = 'How are you?';
$params['html'][] = '<p>Just fine, thank you</p>';

$str = cr_post($params);
echo $str;

I haven't tested it. If it doesn't work then you're going to have to roll your own. Maybe you can publish a github gist so other people can use it!
