使用 STHTTPRequest 框架解析 Soap1.2 教程

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)

https://github.com/mattt/Ono

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
