PHP NuSoap中的XML请求-“ HTTP / 1.1 400错误请求”

Question

我在PHP中使用NuSoap连接到API。

目前，我只是尝试发送由提供API的公司提供的XML字符串示例，但是我收到了HTTP/1.1 400 Bad Request错误。

我直接向公司查询，但是他们说，当他们使用提供的XML以及其他客户时，他们没有任何问题。

我尝试发送的XML是：

![CDATA[<?xml version="1.0" encoding="utf-8" ?>
<Service>
  <Name><![CDATA[Demo]]></Name>
  <Description><![CDATA[Demo Service]]></Description>
  <Version>1.0</Version>
  <Nodes>
    <Node NodeType="Start" NodeID="5" Description="">
      <!-- Comments can be included -->
      <MandatoryProperties>
        <Property Name="MaxLength" Value="0"/>
        <Property Name="EnableSpeedDial" Value="False"/>
      </MandatoryProperties>
     <OptionalSettings/>
      <Branches>
        <Branch Name="Continue" NodeID="20" Description=""/>
      </Branches>
      <DynamicBranches/>
      <DynamicProperties/>
    </Node>
    <Node NodeType="DeliverCall" NodeID="20" Description="Home Phone">
      <MandatoryProperties>
        <Property Name="DestinationNumber" Value="01132211444"/>
        <Property Name="RingDuration" Value="60"/>
      </MandatoryProperties>
      <OptionalSettings/>
      <Branches>
      </Branches>
      <DynamicBranches/>
      <DynamicProperties/>
    </Node>
  </Nodes>
</Service>]]

我得到的答复是：

Response:
HTTP/1.1 100 Continue

我已经使用http://www.validome.org/xml/validate/来验证XML，因为我对XML不熟悉，这是我不得不使用它的几次，所以我不会出现语法错误，但验证工具提供的错误是：

我检查了XML是否没有空格前后。

我注意到的是，在XML中，它将编码设置为utf-8 。 但是，我的请求中的编码似乎是ISO -尽管看起来好像XML字符串中没有任何特殊字符或任何东西。

请求数据：

POST /dev/aspapi/api.asmx HTTP/1.0

如果有人能发现任何问题，我将不胜感激！

完整的连接脚本：

<?php

require_once('./nusoap.php');

error_reporting(E_ALL);
ini_set("display_errors", true);

$client = new nusoap_client('http://xxx.xxx/api.asmx', 'wsdl');

$client->setCredentials('xxxxx', 'xxxxx'); 
$client->response_timeout = 120;

$err = $client->getError();

if($err) {
    echo 'ERROR<br /><pre>' . $err . '</pre><br />';
    exit;
} else {
    echo "<strong><em>Sucessfull connection</em></strong><br /><br />";
}

$proxy = $client->getProxy();

$proxy->setHeaders('<soap:Header><AuthenticationSoapHeader xmlns="https://www.xxxxx.com/aspapi"><Token>xxxxx</Token></AuthenticationSoapHeader></soap:Header>');

$xml = '
![CDATA[<?xml version="1.0" encoding="utf-8" ?>

        <Property Name="EnableSpeedDial" Value="False"/>
      </MandatoryProperties>
     <OptionalSettings/>
      <Branches>
        <Branch Name="Continue" NodeID="20" Description=""/>

    <Node NodeType="DeliverCall" NodeID="20" Description="Home Phone">

        <Property Name="RingDuration" Value="60"/>
      </MandatoryProperties>
      <OptionalSettings/>
      <Branches>
      </Branches>
      <DynamicBranches/>
      <DynamicProperties/>
    </Node>
  </Nodes>
</Service>]]';

$result = $proxy->call('ValidateService', array('serviceXML' => $xml));

$err = $proxy->getError();
if($err) {
    echo 'ERROR<br /><pre>' . $err . '</pre><br />';
    echo '<strong>Request:</strong>';
    echo '<pre>'; print_r($proxy->request); echo '</pre>';
    echo '<strong>Response:</strong>';
    echo '<pre>'; print_r($proxy->response); echo '</pre>';
    exit;
} else {
    echo "<strong><em>Sucessfull connection</em></strong><br /><br />";
}
?>

上面脚本的输出：

Sucessfull connection

附加信息

到目前为止还算不上好运，可以在http://pastebin.com/hF3DYGWP上找到调试字符串的输出。

问题出在标题上。

<soap:Header>开头和结尾标记导致HTTP Error 400 "Bad Request"

$proxy->setHeaders('<soap:Header><AuthenticationSoapHeader xmlns="https://www.xxxxx.com/aspapi"><Token>xxxxx</Token></AuthenticationSoapHeader></soap:Header>');

应该

$proxy->setHeaders('<AuthenticationSoapHeader xmlns="https://www.xxxxx.com/aspapi"><Token>xxxxx</Token></AuthenticationSoapHeader>');
