无法在PHP中接收JSON POST请求 [英] Unable to receive JSON POST request in PHP
问题描述
我将一个JOSN对象从Java传递给PHP。我正在使用jdk 1.8 ang WAMP服务器。
下面是Java代码。
I am passing a JOSN object from Java to PHP. I am using jdk 1.8 ang WAMP server. Below is the Java code.
import java.io.IOException;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClientBuilder;
import org.json.simple.JSONObject;
/**
*
* @author PReeeT Dash
*/
public class FromJava
{
public static void main(String[] args) throws IOException
{
JSONObject json = new JSONObject();
json.put("someKey", "someValue");
CloseableHttpClient httpClient = HttpClientBuilder.create().build();
try
{
HttpPost request = new HttpPost("http://localhost/PGP/JSONReq/tophp.php");
StringEntity params = new StringEntity(json.toString());
request.addHeader("content-type", "application/json");
request.setEntity(params);
httpClient.execute(request);
// handle response here...
} catch (Exception ex)
{
System.out.println("Error: Cannot Estabilish Connection");
}
finally
{
httpClient.close();
}
}
}
PHP脚本:
$data = json_decode(file_get_contents("php://input"));
echo($data);
当我运行PHP文件时,它总是显示一个空页面。任何人都可以帮助我理解为什么它不起作用。
When I run the PHP file it always shows an Empty page. Can anyone please help me understand why is it not working.
当我运行以下PHP代码时,它总是执行else条件。
When I run the following PHP code it always executes the else condition.
if ($_SERVER['REQUEST_METHOD'] == 'POST')
{
$data = json_decode(file_get_contents("php://input"));
echo($data);
}
else
{
echo "XXXXXX";
}
推荐答案
获取您的组织的响应正文.apache.http.client实例接收和例如发送到System.out
Fetch the response body your org.apache.http.client instance receives and e.g. send it to System.out
CloseableHttpResponse response = httpClient.execute(request);
IOUtils.copy(response.getEntity().getContent(), System.out);
对于IOUtils,使用 import org.apache.commons.io.IOUtils;
如果您正在使用maven,则依赖性为
For IOUtils use import org.apache.commons.io.IOUtils;
In case you're using maven the dependency is
<dependency>
<groupId>commons-io</groupId>
<artifactId>commons-io</artifactId>
<version>2.4</version>
</dependency>
您很可能获得输出
Catchable fatal error<: Object of class stdClass could not be converted to string
因为 echo($ data)
不起作用。 json_decode(...)返回一个stdClass。
尝试
because echo($data)
doesn't work. json_decode(...) returns a stdClass.
Try
<?php
if ($_SERVER['REQUEST_METHOD'] == 'POST')
{
// json_decode(..., true) will return an array instead of a stdClass
$data = json_decode(file_get_contents("php://input"), true);
var_export($data);
}
else
{
var_export($_SERVER['REQUEST_METHOD']);
}
而不是。
