iOS 通过 soap 请求调用地址为 asmx 或 wsdl 服务器上的接口

平时调接口都是直接用 AFN 把接口地址放到 post 方法中就可以获取到需要的数据，但如何调用 java或.net 的 webservice 接口，以登录方法为例：

地址是asmx的：

这时候需要通过 AFN 发送 soap 请求。

  1. 构建 soap 请求体
NSString *soapbody = [[NSString alloc] init];
    for(NSString *str in pratams.allKeys)
    {
        soapbody = [soapbody stringByAppendingString:[NSString stringWithFormat:@"<%@>%@</%@>\\",str,[pratams objectForKey:str],str]];
    }

2.根据后台soap格式，拼接 soap 字符串（命名空间可能需要修改 ）

    //使用命名空间： http://tempuri.org/
    NSString *soapStr = [NSString stringWithFormat:
                         @"<?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>\
                         <%@ xmlns=\"http://tempuri.org/\">\
                         %@\
                         </%@>\
                         </soap:Body>\
                         </soap:Envelope>",soapMethod,soapbody,soapMethod];
  1. 对 AFN 相关参数进行设置
AFHTTPSessionManager *manager = [ AppDelegate shareManager];
    manager.responseSerializer = [AFXMLParserResponseSerializer serializer];
    // 设置请求超时时间
    manager.requestSerializer.timeoutInterval = 10;
    // 返回NSData
    manager.responseSerializer = [AFHTTPResponseSerializer serializer];
    // 设置请求头，也可以不设置
    [manager.requestSerializer setValue:@"text/xml; charset=utf-8" forHTTPHeaderField:@"Content-Type"];
    [manager.requestSerializer setValue:[NSString stringWithFormat:@"%zd", soapStr.length] forHTTPHeaderField:@"Content-Length"];
    // 设置HTTPBody
    [manager.requestSerializer setQueryStringSerializationWithBlock:^NSString *(NSURLRequest *request, NSDictionary *parameters, NSError *__autoreleasing *error) {
        return soapStr;
    }];
  1. post 方法
 [manager POST:@"地址" parameters:soapStr progress:nil success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {
        // 把返回的二进制数据转为字符串
        NSString *result = [[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding];
        // 利用正则表达式取出<return></return>之间的字符串
        NSString *regularStr = [NSString stringWithFormat:@"(?<=%@Result\\>).*(?=</%@Result)",soapMethod,soapMethod];
        NSRegularExpression *regular = [[NSRegularExpression alloc] initWithPattern:regularStr options:NSRegularExpressionCaseInsensitive error:nil];
        NSDictionary *dict = [NSDictionary dictionary];
        for (NSTextCheckingResult *checkingResult in [regular matchesInString:result options:0 range:NSMakeRange(0, result.length)]) {
            // 得到字典
            dict = [NSJSONSerialization JSONObjectWithData:[[result substringWithRange:checkingResult.range] dataUsingEncoding:NSUTF8StringEncoding] options:NSJSONReadingMutableLeaves error:nil];
        }
       
        // 请求成功并且结果有值把结果传出去
        if (success && dict) {
            success(dict);
        }
    } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
        if (failure) {
            failure(error);

            //请求失败
        }
    }];

完整代码如下：

+ (void)SOAPData:(NSDictionary *)pratams soapMethod:(NSString *)soapMethod success:(void (^)(id))success failure:(void (^)(NSError *))failure
{

    NSString *soapbody = [[NSString alloc] init];
    for(NSString *str in pratams.allKeys)
    {
        soapbody = [soapbody stringByAppendingString:[NSString stringWithFormat:@"<%@>%@</%@>\\",str,[pratams objectForKey:str],str]];
    }
    //使用命名空间： http://tempuri.org/
    NSString *soapStr = [NSString stringWithFormat:
                         @"<?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>\
                         <%@ xmlns=\"http://tempuri.org/\">\
                         %@\
                         </%@>\
                         </soap:Body>\
                         </soap:Envelope>",soapMethod,soapbody,soapMethod];
    
    

    AFHTTPSessionManager *manager = [ AppDelegate shareManager];
    manager.responseSerializer = [AFXMLParserResponseSerializer serializer];
    // 设置请求超时时间
    manager.requestSerializer.timeoutInterval = 10;
    // 返回NSData
    manager.responseSerializer = [AFHTTPResponseSerializer serializer];
    // 设置请求头，也可以不设置
    [manager.requestSerializer setValue:@"text/xml; charset=utf-8" forHTTPHeaderField:@"Content-Type"];
    [manager.requestSerializer setValue:[NSString stringWithFormat:@"%zd", soapStr.length] forHTTPHeaderField:@"Content-Length"];
    // 设置HTTPBody
    [manager.requestSerializer setQueryStringSerializationWithBlock:^NSString *(NSURLRequest *request, NSDictionary *parameters, NSError *__autoreleasing *error) {
        return soapStr;
    }];
    

    [manager POST:@"地址" parameters:soapStr progress:nil success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {
        // 把返回的二进制数据转为字符串
        NSString *result = [[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding];
        // 利用正则表达式取出<return></return>之间的字符串
        NSString *regularStr = [NSString stringWithFormat:@"(?<=%@Result\\>).*(?=</%@Result)",soapMethod,soapMethod];
        NSRegularExpression *regular = [[NSRegularExpression alloc] initWithPattern:regularStr options:NSRegularExpressionCaseInsensitive error:nil];
        NSDictionary *dict = [NSDictionary dictionary];
        for (NSTextCheckingResult *checkingResult in [regular matchesInString:result options:0 range:NSMakeRange(0, result.length)]) {
            // 得到字典
            dict = [NSJSONSerialization JSONObjectWithData:[[result substringWithRange:checkingResult.range] dataUsingEncoding:NSUTF8StringEncoding] options:NSJSONReadingMutableLeaves error:nil];
        }
       
        // 请求成功并且结果有值把结果传出去
        if (success && dict) {
            success(dict);
        }
    } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
        if (failure) {
            failure(error);

            [[FunctionManager sharedHandel] showAlert:@"网络连接失败" duration:1.0];
        }
    }];
}

调用（比如登录）：

 NSDictionary * paramDict = @{@"userName":_nameTextField.text,@"passWord":_passwordTextField.text};
        
        [AFNwebManager SOAPData:paramDict soapMethod:@"getUserList" success:^(id responseObject) {
            
            NSLog(@"%@",responseObject);
            //获取到数据，进行操作
        } failure:^(NSError *error) {
            
            //获取失败
        }];

如果地址是wsdl的:

注意 soap 请求体的标签可能会不一样，可以下载并借助 soapUI （下载后将接口网址放上去，会生成对应的 soap 格式）

        soapbody = [soapbody stringByAppendingString:[NSString stringWithFormat:@"<%@>%@</%@>\\",str,[pratams objectForKey:str],str]];
    }
