1.STHTTPRequest框架地址
https://github.com/nst/STHTTPRequest
将 STHTTPRequest .h STHTTPRequest.m 文件拖入工程中引入头文件即可
2.Ono框架(解析XML用)
将 Ono 文件夹拖入到工程中引入头文件,链接到 libxml2.dylib ,在 Header Search Path 中 添加 /usr/include/libxml2

以下是 SOAP 1.2 请求和响应示例。所显示的占位符需替换为实际值。
http://webservice.webxml.com.cn/WebServices/MobileCodeWS.asmx?op=getMobileCodeInfo
POST /WebServices/MobileCodeWS.asmx HTTP/1.1
Host: webservice.webxml.com.cn
Content-Type: application/soap+xml; charset=utf-8
Content-Length: length <?xml version="1.0" encoding="utf-8"?>
<soap12:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap12="http://www.w3.org/2003/05/soap-envelope">
<soap12:Body>
<getMobileCodeInfo xmlns="http://WebXml.com.cn/">
<mobileCode>string</mobileCode>
<userID>string</userID>
</getMobileCodeInfo>
</soap12:Body>
</soap12:Envelope>
-------------------------------------------------------------------------------------------------------
//前期信息的准备
//请将XXXXXXXXXXX换成自己的电话号码,否则请求会失败
NSString *msgLength = [NSString stringWithFormat:@"%d",[@"XXXXXXXXXXX" length]];
NSString *serviceAddress = @"http://webservice.webxml.com.cn/WebServices/MobileCodeWS.asmx";
NSString *soapMsg = [NSString stringWithFormat:
@"<?xml version=\"1.0\" encoding=\"utf-8\"?>"
"<soap12:Envelope "
"xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" "
"xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" "
"xmlns:soap12=\"http://www.w3.org/2003/05/soap-envelope\">"
"<soap12:Body>"
"<getMobileCodeInfo xmlns=\"http://WebXml.com.cn/\">"
"<mobileCode>%@</mobileCode>"
"<userID>%@</userID>"
"</getMobileCodeInfo>"
"</soap12:Body>"
"</soap12:Envelope>", @"XXXXXXXXXXX", @""];
NSMutableDictionary *requestHeadersDic = [[NSMutableDictionary alloc] initWithObjectsAndKeys:
@"application/soap+xml; charset=utf-8", @"Content-Type" ,
msgLength, @"Content-Length",
nil]; //组织请求内容
STHTTPRequest *request = [STHTTPRequest requestWithURLString:serviceAddress];
request.HTTPMethod = @"POST";
request.requestHeaders = requestHeadersDic;
request.rawPOSTData = [soapMsg dataUsingEncoding:NSUTF8StringEncoding]; //注册block回调
request.completionBlock = ^(NSDictionary *headers, NSString *body) {
NSLog(@"%@", headers);
};
request.errorBlock = ^(NSError *error) {
NSLog(@"%@", error);
};
request.downloadProgressBlock = ^(NSData *data, NSInteger totalBytesReceived, NSInteger totalBytesExpectedToReceive) {
NSLog(@"%ld", (long)totalBytesReceived);
};
request.completionDataBlock = ^(NSDictionary *headers, NSData *body) {
ONOXMLDocument *document = [ONOXMLDocument XMLDocumentWithData:body error:nil];
NSLog(@"%@", document);
}; //开始异步请求
[request startAsynchronous];
分析:
请求分为3个部分:
1.请求的地址 http://webservice.webxml.com.cn/WebServices/MobileCodeWS.asmx ,此部分会被Request自动解析出 Host Post 地址
2.请求的头部 Content-Type Content-Length
3.请求的实体 (转换成了二进制文件)
4.得到的数据进行 XML 或者 JSON 解析
