如何从 php 中调用的 java 文件中获取返回值

我在PHP中使用HttpURLConnection来调用Java文件。在 JAVA 中如何返回字段内容(字符串(，在 PHP 中如何接收它们？谢谢。对任何可以提供帮助的人都很棒。哈哈。

示例代码：

爪哇岛：

   @Controller
@RequestMapping("/rest")
public class ProjectController {

    @RequestMapping(value = "/ediresponceback", method = RequestMethod.POST)
    public String ediResponceBack(HttpServletRequest webRequest) throws FileNotFoundException, IOException {
        ParseEDI271 myParser = new ParseEDI271();
        if (webRequest.getParameter("edistring") != null) {
            myParser.setEDI271(webRequest.getParameter("edistring"));
        } else {
            myParser.setEDI271("Responce not found");
        }
        try {
            myParser.parseEDI();
        } catch (FormatException e) {
            e.printStackTrace();
        }
        String ediTextMessage = myParser.getEdiTextMessage();
        return ediTextMessage;
    }
}file?
        con.disconnect();
    }

我最近参加了同样的事情。我花了一段时间才弄清楚，但这就是最终奏效的方法。

JS FILE (AJAX Request) --> PHP SHELL SCRIPT --> JS FILE我将它们称为 A、B 和 C

A 看起来像这样：

function verify(){
        $.ajax({
        url:"scripts/shell.php", //the page containing php script
        type: "post", //request type,
        dataType: 'json',
        data: {data1: "hi", data2: "hello", data3: "bye"}, //OPTIONAL, Used as arguments for js file down the road. 
        success:function(result){
         console.log(result.abc);
       }
     });
    }

相当标准的AJAX要求

B 看起来像这样：

<?php  
$EH= $_POST['data1'];
$EHH = $_POST['data2'];
$EHHH = $_POST['data3'];
echo json_encode(array("abc" => shell_exec("...PATH-TO-JS/file.js 2>&1 $EH $EHHH $EHHH")));
?>

注意这个 shell 脚本echo 的，并将结果encodes回数组abc如 A 末尾所述。

C 看起来像这样：

var system = require('system')
var H = system.args[1]
var Hi = system.args[2]
var Hii = system.args[3]
if(1 > 2){
 console.log("Passing Result Back") // OR true
}

然后，该结果将传递回 shell，后者进行编码并传递回调用它的原始 js 文件。

希望这有帮助。

以下是用于将字符串发送到 Java 应用程序的 PHP 代码，并将获得字符串格式的响应：

<?php
// The data to send to the API
$postData = array(
    'data' => 'Test'
);
//echo json_encode($postData);
// Create the context for the request
$context = stream_context_create(array(
    'http' => array(
        'method' => 'POST',
        'header' => "Content-Type: application/jsonrn",
        'content' => json_encode($postData)
    )
));

// Send the request
$response = file_get_contents('http://localhost:8080/EDI271Parser/rest/ediresponceback/', FALSE, $context);
// Check for errors
if($response === FALSE){
    die('Error');
}

// Print the date from the response
echo $response;
?>
