iOS中发送xml给服务器

一、用URLSession请求

NSString *soapStr = [NSString stringWithFormat:@""1.0\" encoding=\"utf-8\"?>\
 "http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\"\
 xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\">\
 \
 \
 \
 "targetNameSpace地址/\">\
 test\
 test\
 \
 \
 "];
  
 NSURL *url=[NSURL URLWithString:@"你自己wsdl文档中对应的endpoint address"];
  
 NSMutableURLRequest *request=[NSMutableURLRequest requestWithURL:url];
  
 // 访问方式
 [request setHTTPMethod:@"POST"];
  
 // 设置请求头(请求头也可以不设置，前两个设不设置都一样，应该默认的，但是SOAPAction我怎么都设置不对，不设置也可以，干脆不设置了)
 // [request addValue:@"text/xml; charset=utf-8" forHTTPHeaderField:@"Content-Type"];
//  [request addValue:[NSString stringWithFormat:@"%zd", soapStr.length] forHTTPHeaderField:@"Content-Length"];
 //    [request addValue:@"nameSpace/methodName" forHTTPHeaderField:@"SOAPAction"];
  
 // body内容
 [request setHTTPBody:[soapStr dataUsingEncoding:NSUTF8StringEncoding]];
  
 NSURLSession *session = [NSURLSession sharedSession];
  
 NSURLSessionDataTask *task = [session dataTaskWithRequest:request completionHandler:^(NSData * _Nullable data, NSURLResponse * _Nullable response, NSError * _Nullable error) {
 NSString *result = [[NSString alloc] initWithData:data  encoding:NSUTF8StringEncoding];
  
 WJLog(@"进入成功回调Session-----结果：%@----请求地址：%@", result, response.URL);
  
 if (error) {
 WJLog(@"Session----失败----%@", error.localizedDescription);
 }
 }];
  
 [task resume];

二、用AFNetworking请求

一开始想用manager发请求，直接把XML当params发POST肯定是直接挂了，于是想要设置HTTPBody要不用AFHTTPRequestOperation？

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17

NSMutableURLRequest *request=[ NSMutableURLRequest requestWithURL:url]; [request setHTTPMethod:@ "POST" ]; [request setHTTPBody:[soapStr dataUsingEncoding: NSUTF8StringEncoding ]]; AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request]; // 设置返回数据格式 operation.responseSerializer = [AFHTTPResponseSerializer serializer]; [operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation * _Nonnull operation, id _Nonnull responseObject) { NSString *result = [[ NSString alloc] initWithData:responseObject encoding: NSUTF8StringEncoding ]; WJLog(@ "AFN--成功--结果：%@----返回数据%@" , result, responseObject); } failure:^(AFHTTPRequestOperation * _Nonnull operation, NSError * _Nonnull error) { WJLog(@ "AFN--失败--%@" , error.localizedDescription); }]; [operation start];

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17

NSMutableURLRequest *request=[ NSMutableURLRequest requestWithURL:url]; [request setHTTPMethod:@ "POST" ]; [request setHTTPBody:[soapStr dataUsingEncoding: NSUTF8StringEncoding ]]; AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request]; // 设置返回数据格式 operation.responseSerializer = [AFHTTPResponseSerializer serializer]; [operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation * _Nonnull operation, id _Nonnull responseObject) { NSString *result = [[ NSString alloc] initWithData:responseObject encoding: NSUTF8StringEncoding ]; WJLog(@ "AFN--成功--结果：%@----返回数据%@" , result, responseObject); } failure:^(AFHTTPRequestOperation * _Nonnull operation, NSError * _Nonnull error) { WJLog(@ "AFN--失败--%@" , error.localizedDescription); }]; [operation start];

这一看感觉和 NSURLSession 没多大差别，还是想用manager，关键问题就在于设置request的HTTBbody为XML，但是AFHTTPSessionManager已经把request封装了，默认用的params，怎么改？于是想改动或者添加AFN内部方法，但是总感觉这样不好，万一更新库了又要搞一遍。于是想能否拦截这个request，或者通过manager.requestSerializer设置HTTPBody，敲set浏览一下没有HTTPBody字眼的，用KVC也不行，那样还是相当于把XML当params传了，伤心绝望之时看到这个方法
[manager.requestSerializer setQueryStringSerializationWithBlock:^ NSString  *( NSURLRequest  *request,  NSDictionary  *parameters,  NSError  *__autoreleasing *error) {
   //
}]
一看里面有request 有 params 高兴了，说不定在这里能拦截，于是直接写
[manager.requestSerializer setQueryStringSerializationWithBlock:^ NSString  *( NSURLRequest  *request,  NSDictionary  *parameters,  NSError  *__autoreleasing *error) {
    return  soapStr;
}]，请求成功，高兴了。

接下来另一个问题了，简单封装一下，我收到的是二进制，所以把AFN封装成了个工具类，供大家参考，欢迎提出改进

/**
*  请求SOAP，返回NSData
*
*  @param url      请求地址
*  @param soapBody soap的XML中方法和参数段
*  @param success  成功block
*  @param failure  失败block
*/

+ ( void )SOAPData:( NSString  *)url soapBody:( NSString  *)soapBody success:( void  (^)( id  responseObject))success failure:( void (^)( NSError  *error))failure {

    NSString  *soapStr = [ NSString  stringWithFormat:
                         @"\
                         //www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\"\
                         xmlns:soap=\"http: //schemas.xmlsoap.org/soap/envelope/\">\
                         \
                         \
                         %@\
                         ",soapBody];

    AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
    manager.responseSerializer = [AFXMLParserResponseSerializer serializer];

    // 设置请求超时时间
    manager.requestSerializer.timeoutInterval = 30;

    // 返回NSData
    manager.responseSerializer = [AFHTTPResponseSerializer serializer];

    // 设置请求头，也可以不设置
    [manager.requestSerializer setValue:@ "application/soap+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:url parameters:soapStr success:^( NSURLSessionDataTask  * _Nonnull task,  id   _Nonnull 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之间的字符串
        NSRegularExpression  *regular = [[ NSRegularExpression  alloc] initWithPattern:@ "(?<=return\\>).*(?=  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);
        }
    }];
}
