iOS:PHP使用SOAP的web服务在调用时返回null

创建了一个扩展名为.php的web服务，我正在通过soap传递参数。但它的回报超出了我的理解。我还使用正确的输入检查RestClient，然后返回实际输出。这在代码中是不正确的。可能出了什么问题

我的输入xml结构是

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
 <soap:Header>
 </soap:Header>
 <soap:Body>
   <getUpdates>
  <user_location></user_location>
  <application_type>FC</application_type>
  <last_updated_date>2014-11-25</last_updated_date>
  <platform>Android</platform>
  </getUpdates>
 </soap:Body>
</soap:Envelope>

尝试添加

[request addRequestHeader:@"Accept" value:@"text/xml"];

到您的Web服务请求。您正在调用的REST服务默认为json。许多人通常会根据请求返回XML。

您将得到JSON。这对于REST服务来说是相当正常的。听起来你的PHP服务没有返回XML.ohh，我明白了。让我查一查。

"SOAP-ENV:Envelope" =     {
        "SOAP-ENV:Body" =         {
            "ns1:getUpdatesResponse" =             {
                return =                 {
                    "SOAP-ENC:arrayType" = "xsd:anyType[0]";
                    "xsi:type" = "SOAP-ENC:Array";
                };
                "xmlns:ns1" = "http://schemas.xmlsoap.org/soap/envelope/";
            };
        };
        "SOAP-ENV:encodingStyle" = "http://schemas.xmlsoap.org/soap/encoding/";
        "xmlns:SOAP-ENC" = "http://schemas.xmlsoap.org/soap/encoding/";
        "xmlns:SOAP-ENV" = "http://schemas.xmlsoap.org/soap/envelope/";
        "xmlns:xsd" = "http://www.w3.org/2001/XMLSchema";
        "xmlns:xsi" = "http://www.w3.org/2001/XMLSchema-instance";
    };

[request addRequestHeader:@"Accept" value:@"text/xml"];
