Question

我刚接触PHP Nusoap，我试图运行我的程序，当我print_r($client)时，我遇到了这种错误。这是错误：

错误：在第1行解析SOAP有效内容时出现XML错误：文档结束无效

我在google中发现一些相关的主题，文章和问题，但是如果有答案则无法帮助或解决我的问题我还打印了我的请求并在此处回复了详细信息：

代码：

webservice_server.php

<?php 
require_once('lib/nusoap.php');

$server = new soap_server();

$server->configureWSDL('Database Data Insertion', 'urn:Insert');
//$server->soap_defencoding = 'utf-8';
$server->register('InsertData',
    array(
        'data' => 'xsd:data',       
        'data1' => 'xsd:data1',
        'data2'  => 'xsd:data2',
        'data3'  => 'xsd:data3',
        'data4' => 'xsd:data4',
    ),
    array(
        'return' => 'xsd:string'        
    ),
    'urn:Insert',
    'urn:Insertwsdl#InsertData',
    'rpc',
    'literal',
    'Retrieve data from  the database'
    );

    function InsertData($data, $data1, $data2, $data3, $data4){

        $db_host = '127.0.0.1';
        $db_username = 'sample';
        $db_password = '' ;
        $db_name = 'sample';

        $conn = new mysqli($db_host, $db_username, $db_password, $db_name);

        if ($conn->connect_error) {
            trigger_error('Database connection failed: ', $conn->connect_error, E_USER_ERROR);
        }

        $sql = "SELECT * FROM sample_transaction ";

        $query = $conn->query($sql);

        if ($query->num_rows > 0) {
            while ($row = $query->fetch_assoc()) {
                echo "<br /> Data : " .$row['data'];
                echo "<br /> Data1 : " .$row['data1'];
                echo "<br /> Data2 : "  .$row['data2'];
            }

        } else {
            echo "0 Results";
        }
    }

    $HTTP_RAW_POST_DATA = isset($HTTP_RAW_POST_DATA)? $HTTP_RAW_POST_DATA : '' ;
    $server->service($HTTP_RAW_POST_DATA);
?>

webservice_client.php

<?php
require_once('lib/nusoap.php');

$data = json_decode(file_get_contents("php://input"), true);


$data = $data['data'];
$data1 = $data['data1'];
$data2 = $data['data2'];
$data3= $data['data3'];
$data4 = $data['data4'];
$client = new nusoap_client('http://sampleserver:8544/Nusoap/webservice_server.php?wsdl', true);

$datas = array(
     'data' => $data,
    'data1' => $data1,
    'data2'=> $data2,
    'data3' => $data3,
    'data4' => $data4,  
    );

$result= $client->call('InsertData', $datas);

print_r($result);

echo "<br /><pre>" .$client. "</pre>";
echo "<h2>Request</h2>";
echo "<pre>" .htmlspecialchars($client->request, ENT_QUOTES). "</pre>";
echo "<h2>Response</h2>";
echo "<pre>" .htmlspecialchars($client->response, ENT_QUOTES). "</pre>";
?>

我只是评论$server->soap_defencoding，因为如果没有注释，响应将会有text/xml charset=utf-8之类的内容类型。如果我没有相同的内容类型，我的意思是字符集，这也是一个问题吗？根据我上面发布的代码，我如何解决这个问题，因为我一直在寻找2天的解决方案。有人可以指出我哪里出错了，我该如何解决这个问题？顺便说一句，代码只会从数据库中选择，它只从数据库中检索少量数据并得到该错误。任何帮助表示赞赏。非常感谢。

Answer 1

请保持

$server->soap_defencoding = 'utf-8';

添加

$client->soap_defencoding = 'utf-8'; 
$client->encode_utf8 = false;
$client->decode_utf8 = false;

如果错误仍然存在，请添加

$server->encode_utf8 = false;
$server->decode_utf8 = false;

Answer 2

我在通过https发布xml时遇到此错误。通过http传递它是好的。经过几天的谷歌搜索并试图改变我的php.ini上的一些东西，我弄乱了整个文件，所以我选择重新安装php5，它工作。

我使用以下命令重新安装php

apt-get install libapache2-mod-php5

Answer 3

我有同样的错误。我试着解决它一天。不幸的是，我没有解决方案。在追踪我的php代码之后，我在config.php文件中看到了CREATE PROC MyCriticalWork(@MyParam INT) AS DECLARE @LockRequestResult INT SET @LockRequestResult=0 DECLARE @MyTimeoutMiliseconds INT SET @MyTimeoutMiliseconds=5000--Wait only five seconds max then timeouit BEGIN TRAN EXEC @LockRequestResult=SP_GETAPPLOCK 'MyCriticalWork','Exclusive','Transaction',@MyTimeoutMiliseconds IF(@LockRequestResult>=0)BEGIN /* DO YOUR CRITICAL READS AND WRITES HERE */ --Release the lock COMMIT TRAN END ELSE ROLLBACK TRAN。如果您只删除该行或将其更改为ini_set('display_errors', 1);，它将像魅力一样工作。

我希望这有助于其他人在他们的SOAP（nusoap）项目库或文件中克服这个问题。

度过美好的一天。
