我在IOS中使用ASIHTTPRequest。我有一个wsdl/soap web服务。当我调用我的web serives时,我收到了错误400坏请求。我使用的是这个代码:
NSData *xmlData = // I construct the soap message witk soapui
NSURL *url = [NSURL URLWithString:@"https:myUrlWSDL"];
self.currentRequest = [ASIFormDataRequest requestWithURL:url];
[self.currentRequest appendPostData:xmlData];
[self.currentRequest setDelegate:self];
[self.currentRequest startAsynchronous];
[[currentRequest requestHeaders] description];
NSLog(@"Headers %@",[currentRequest requestHeaders]);
NSLog向我显示:headers(null)。
我的第一个问题,为什么Headers为null?这正常吗??
在控制台中,我收到了400个错误的请求。在代表中,我做:
- (void)requestFinished:(ASIHTTPRequest *)request
{
NSLog(@"headers: %@", [self.currentRequest responseHeaders]);
}
它向我显示:
"Cache-Control" = "no-store, no-cache, must-revalidate, post-check=0, pre-check=0";
Connection = close;
"Content-Encoding" = gzip;
"Content-Length" = 285;
"Content-Type" = "text/xml; charset=utf-8";
Date = "Fri, 10 Jun 2011 01:25:40 GMT";
Expires = "Thu, 19 Nov 1981 08:52:00 GMT";
Pragma = "no-cache";
Server = Apache;
"Set-Cookie" = "symfony=...4; path=/";
Vary = "Accept-Encoding,User-Agent";
"X-Powered-By" = "PHP/5.3.3";
我的问题是:为什么400坏请求会出错?我的请求有什么问题?或者问题出在我的肥皂上?
谢谢你的回答。
据我所知,在发出SOAP/WSDL请求时,您需要在请求中设置一些标头
Content-Type: text/xml
Content-Length: length of your message in bytes
SOAPAction: your SOAPAction goes here
ASIHTTPRequest设置内容长度本身(不确定内容类型)。不过,您必须自己添加SOAPAction标头。
