iOS 与webService

前几日做了一个小项目,后台是web服务,之前没接触过,后来找了很多资料最终解决,链接web服务不想链接webAPI,给个链接就行了,web服务需要拼接请求报文,其中要拼接头部

如 

 "Content-Length" = 421;//包体长度    "Content-Type" = "text/xml; charset=utf-8";//类型    Host = "www.XXXXXXXX.com";//主机链接    soapAction = "http://tempuri.org/IAppService/DataOperate";//调用的方法

这个是请求的head

接下来就是拼接body里的内容

<?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:Body><DataOperate xmlns="http://tempuri.org/"><span style="color:#ff9900;"><strjson></span><span style="color:#ff0000;">{"funCode":"1101","funParams":"{\"pushNumber\":0,\"userId\":\"4A2D8F8FE0A84532A60EA31B8CB8ABE5\"}"}</span></strjson></DataOperate></soap:Body></soap:Envelope> 是不是很奇怪这串红色的内容,其实就是需要拼接参数,这个和其他的webservice的请求不太一样,这里是要给服务器拼接一串json字符串,当时搞了很久才弄好,<pre name="code" class="objc"><span style="color:#ff9900;"><strjson>是参数便签</span>

<span style="color:#ff9900;"></span>

这些弄好后就需要请求了,使用第三方AF和苹果自带的都行,下面我贴出我的请求代码

        //任意一个控制器内请求

    [arr addObject:[NSDictionary dictionaryWithObjectsAndKeys:[NSString stringWithFormat: @"{\"funCode\":\"1101\",\"funParams\":\"{%@:%d,%@:%@}\"}",@"\\\"pushNumber\\\"",0,@"\\\"userId\\\"",@"\\\"4A2D8F8FE0A84532A60EA31B8CB8ABE5\\\""] ,@"strjson", nil]];    NSString *soapMsg=[SoapHelper arrayToDefaultSoapMessage:arr methodName:@"DataOperate"];    [helper asyncServiceMethod:@"DataOperate" soapMessage:soapMsg];
