最近在工作中需要请求第三方的一个java版的接口，起初是使用数组进行传参，代码写完之后发现接口死活调试不通，总是提示传参为空，纠结了很久之后，决定尝试使用字符串传参的方式来请求接口，没想到这次居然调试成功了，这让我有了研究这两者究竟有何区别的兴趣。

本地的测试代码如下：
curl.php

<span><span><?php</span><span><span>function</span><span>curl_post</span><span>(<span>$url</span>, <span>$data</span>)</span>{</span><span>$ch</span> = curl_init();
     curl_setopt(<span>$ch</span>, CURLOPT_URL, <span>$url</span>);
     curl_setopt(<span>$ch</span>, CURLOPT_RETURNTRANSFER, <span>1</span>);
     curl_setopt(<span>$ch</span>, CURLOPT_POST, <span>1</span>);
     curl_setopt(<span>$ch</span>, CURLOPT_POSTFIELDS, <span>$data</span>);
     <span>$output</span> = curl_exec(<span>$ch</span>);
     curl_close(<span>$ch</span>);
     <span>return</span><span>$output</span>;
}

<span>$params</span> = <span>array</span>();
<span>$params</span>[<span>'username'</span>] = <span>'ben'</span>;
<span>$params</span>[<span>'password'</span>] = <span>'lalala'</span>;
print_r(curl_post(<span>'http://localhost/curl/post.php'</span>, <span>$params</span>));

<span>$params</span> = <span>array</span>();
<span>$params</span>[<span>'username'</span>] = urlencode(<span>'ben'</span>);
<span>$params</span>[<span>'password'</span>] = urlencode(<span>'lalala'</span>);
<span>$paramsStr</span> = <span>"username={$params['username']}&password={$params['password']}"</span>;
print_r(curl_post(<span>'http://localhost/curl/post.php'</span>, <span>$paramsStr</span>));

<span>?></span></span>

登录后复制

post.php

<span><?php</span><span>echo</span><span>"-------php://input-----<br/>"</span>;
var_dump(@file_get_contents(<span>'php://input'</span>));
<span>echo</span><span>"-------post-----<br/>"</span>;
var_dump(<span>$_POST</span>);
<span>echo</span><span>"-------server-----<br/>"</span>;
var_dump(<span>$_SERVER</span>);

登录后复制

执行结果可以参照如下截图：
