iOS--对接soap协议接口

最近在对接soap协议接口,分别使用AFN和系统自带方法进行解析。soap协议具体是什么就不阐述了,可以自行百度。

说一下需要注意的地方:

1,iOS与soap协议接口对接,参数要传xml格式的字符串,具体格式看接口说明,务必保持一致;

2,soap1.1和soap1.2使用思路是一样的,但是设置的参数不一样,具体看代码;

3,soap协议的返回值也是xml格式的,需要进行xml解析,获取需要节点下的数据(这里强调一点,可以根据某个节点获取需要的数据,但是也可以不管xml的节点,直接通过根节点获取需要的数据,这个是看后台怎么返回的).

首先看一下要传递的参数格式:说白了就是一个请求体,只不过是xml格式的而已

NSString *soapMessage = [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:Body> \
                         <xiaoxi xmlns= \"http://tempuri.org/ \"> \
                         <typeValue>%@</typeValue> \
                        </xiaoxi> \
                         </soap:Body> \
                         </soap:Envelope>",@"147"];

用系统自带的方法进行解析:

#pragma mark - 用系统自带的
- (void)postWithSoapMessage:(NSString *)message {
    
    // url
    NSURL *url = [NSURL URLWithString:XMHTTPADDRESS];
    // request
    NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
    // 设置POST请求方式
    [request setHTTPMethod:@"POST"];
    // SOAPAction  soap1.1必须设置 soap1.2不设置
    [request addValue:@"http://tempuri.org/UserLogin" forHTTPHeaderField:@"SOAPAction"];
    /*
     * Content-Type
     * soap1.1  text/xml; charset=utf-8
     * soap1.2 application/soap+xml; charset=utf-8
     */
    [request addValue:@"text/xml; charset=utf-8" forHTTPHeaderField:@"Content-Type"];
    // 请求字节数
    [request addValue:[NSString stringWithFormat:@"%zd", message.length] forHTTPHeaderField:@"Content-Length"];
    // 设置请求体 utf-8编码
    [request setHTTPBody:[message dataUsingEncoding:NSUTF8StringEncoding]];
    // session
    NSURLSession *session = [NSURLSession sharedSession];
    // task
    NSURLSessionDataTask *task = [session dataTaskWithRequest:request completionHandler:^(NSData * _Nullable data, NSURLResponse * _Nullable response, NSError * _Nullable error) {
        // 结果
        NSString *result = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
        
        XMLog(@"result = %@",result);
    }];
    [task resume];
}

用AFN进行解析

//POST请求  这里稍微封装了下,便于自己使用,看主要的就可以....
- (void)postWithSoapAction:(NSString *)action parameters:(NSString *)soapMessage success:(Success)success failure:(Failure)failure {
    
    afnManager.responseSerializer = [AFHTTPResponseSerializer serializer];
    afnManager.requestSerializer = [AFHTTPRequestSerializer serializer];
    /*
     * 一般情况AFN请求参数只能传字典
     * 但是可以在这个方法里将请求参数变成字符串形式
     */
    [afnManager.requestSerializer setQueryStringSerializationWithBlock:^NSString * _Nonnull(NSURLRequest * _Nonnull request, id  _Nonnull parameters, NSError * _Nullable __autoreleasing * _Nullable error) {
        
        return soapMessage;
    }];
    // 请求设置
    [afnManager.requestSerializer setValue:@"text/xml; charset=utf-8" forHTTPHeaderField:@"Content-Type"];
    [afnManager.requestSerializer setValue:[NSString stringWithFormat:@"%zd", soapMessage.length] forHTTPHeaderField:@"Content-Length"];
    [afnManager.requestSerializer setValue:[NSString stringWithFormat:@"http://tempuri.org/%@",action] forHTTPHeaderField:@"SOAPAction"];
    
    // post请求
    [afnManager POST:XMHTTPADDRESS parameters:soapMessage progress:nil success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {
        [SVProgressHUD dismiss];
        if (responseObject) {
            
            NSString *response = [self getJsonStringWithData:responseObject];
            success(response);
        }else {
            XMLog(@"%@",@"请求失败");
        }
        
    } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
        
        failure(error);
    }];
}
