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

我在PHP中使用NuSoap连接到API

目前，我只是简单地尝试发送一个由提供API的公司提供的示例XML字符串，但是我收到一个

HTTP/1.1400错误请求

我直接向该公司提出了这个问题，但他们说，当他们使用他们提供的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>]]

我曾经验证过XML，因为我没有XML方面的经验，这是我不得不使用它的少数几次之一，因此我不想在发现任何语法错误时大惊小怪，但验证工具提供的错误是：


我已经检查过XML上是否没有前导或尾随空格

我注意到，在XML中，它将编码设置为
utf-8
。然而，我的请求中的编码似乎是
ISO
——尽管看起来XML字符串中没有任何特殊字符或任何内容

请求数据：

POST /dev/aspapi/api.asmx HTTP/1.0
Host: www.xxxxx.com
User-Agent: NuSOAP/0.9.5 (1.123)
Content-Type: text/xml; charset=ISO-8859-1
SOAPAction: "https://www.xxxxx.com/ASPAPI/ValidateService"
Authorization: Basic bWVkaWFoYXdrOm1lZGlhaGF3aw==
Content-Length: 2127

如果有人能发现这有什么问题，我将不胜感激

完整连接脚本：

<?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 = '

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

$err = $proxy->getError();

    echo '<strong>Request:</strong>';

问题在于标题

打开和关闭标记导致HTTP错误400“错误请求”

$proxy->setHeaders（'xxxxx'）；

应该是

$proxy->setHeaders（'xxxxx'）；
尝试更改此
！[CDATA[
到此
并从xml末尾删除
]
，因为使用
！[CDATA[
开头和
]
结尾xml不太好-formed@elitechief21XML必须用
CDATA
包装（根据提供API的公司）API的创建者有一个测试门户，允许您验证XML字符串——当我将XML字符串放入他们门户中的验证工具时，它返回一个成功。因此，这肯定与我如何发送它有关。这听起来不太正确……您使用它来指定不应由xml解析器解析的文本数据。将
放在xml的根元素之外是格式不好的，也没有任何意义，因为你基本上是告诉解析器不要解析任何xml，不管xml的格式如何，你能发布你正在上传的代码吗？我在使用基于https的c#webservice时遇到了类似的问题。我收到HTTP错误：不支持的HTTP响应状态400错误请求。我想我也有头球问题，但根据你的解决方案，我没有代币。
