我试图将参数从 java 小程序页面传递到 php 页面，特别是在 theme-woocommerce.php 中。Java 页面将涉及将特定关键字发送到 theme-woocommerce.php 的过程。
例如：
用户将输入句子“我想买蓝色球衣”。用户将单击“发送”按钮 Java 部分将处理并获取关键字“Blue Jersey”
然后同时，“Blue Jersey”关键字将被发送到使用http-post的php页面。
我现在面临的问题是我真的不知道应该如何以及在哪里将 post 数组放在 php 页面中。
这是将参数传递给php页面的java部分：
try {
String data2 = URLEncoder.encode("keyword", "UTF-8") + "=" + URLEncoder.encode(system.askquestion(instring,outstring,getkeyword)[1], "UTF-8");
String data = data2 ;
String inLine;
URL u1 = new URL("http://localhost/echo.php");
URLConnection uc1 = u1.openConnection();
uc1.setDoOutput(true);
OutputStreamWriter out = new OutputStreamWriter(uc1.getOutputStream());
out.write(data);
out.flush();
BufferedReader in = new BufferedReader( new InputStreamReader( uc1.getInputStream() ) );
while ((inLine = in.readLine()) != null) {
System.out.println(inLine);
}
in.close();
}
catch( Exception E ) {
E.printStackTrace();
}
}
return false;
}
这个是theme-woocommerce.php 代码：
<form role="search" method="get" id="searchform" class="searchform" action="<?php echo home_url();?>">
<label class="screen-reader-text" for="s"><?php _e('Search for:', 'woothemes'); ?></label>
<input type="text" value="<?php the_search_query(); ?>" name="s" id="s" class="field s" placeholder="<?php _e('Search for products', 'woothemes'); ?>" />
<input type="image" class="submit btn" name="submit" value="<?php _e('Search', 'woothemes'); ?>" src="<?php echo get_template_directory_uri(); ?>/images/ico-search.png">
<?php if ($woo_options['woo_header_search_scope'] == 'products' ) { echo '<input type="hidden" name="post_type" value="product" />'; } else { echo '<input type="hidden" name="post_type" value="post" />'; } ?>
</form>
<div class="fix"></div>
这是我的问题：
- 我可以将参数传递给 theme-woocommerce.php
- 我应该如何以及在哪里将$_POST["keyword"]放入 theme-woocommerce.php
我是否可以使用从 java 页面接收输入的函数搜索。
public boolean handleEvent(Event e)
{ String instring, outstring,getkeyword = null ; if ((( e.target instanceof TextField ) || ( e.target instanceof Button )) && ( e.id == Event.ACTION_EVENT )) { instring = questions.getText();outstring = new String(); if ( instring.length() > 0 ) { answer.appendText("\nYou: " + instring + "\n" ); answer.appendText( "Faris: " + system.askquestion(instring,outstring,getkeyword) [0] + "\n" ); questions.setText(" "); } if ( e.target instanceof Button ) { questions.requestFocus(); } String truee = URLEncoder.encode(system.askquestion(instring , outstring, getkeyword)[1], "UTF-8"); String formURL = "http://localhost/echo.php"; // this should be whatever home_url() in PHP returns URL url = new URL(formURL + "?s=" + truee); // s because there is <input ... name="s"...> in the form InputStream inputStream = url.openStream(); try { // ... process the returned response } finally { inputStream.close(); }
