如何将AFNetworking服务调用转换为使用AFHTTPSessionManager [英] How to convert AFNetworking service invoke to use AFHTTPSessionManager

问题描述

这是我当前对（asmx）SOAP Web服务的调用：

  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> 
<保存xmlns = \http://www.myapp.com/\> 
< par1>％i< / par1> 
< par2>％@< / par2> 
< par3>％@< / par3> 
< / Save> 
< / soap：Body> 
< / soap：Envelope>，par1，par2，par3 
]; 
 NSURL * url = [NSURL URLWithString：@http：//....asmx]; 
 NSMutableURLRequest * request = [NSMutableURLRequest requestWithURL：url]; 
 
 NSString * msgLength = [NSString stringWithFormat：@％lu，（unsigned long）[soapMessage length]]; 
 
 [请求addValue：@text / xml; charset = utf-8forHTTPHeaderField：@Content-Type]; 
 [请求addValue：msgLength forHTTPHeaderField：@Content-Length]; 
 
 [请求setHTTPMethod：@POST]; 
 [request setHTTPBody：[soapMessage dataUsingEncoding：NSUTF8StringEncoding]]; 
 
 AFHTTPRequestOperation * operation = [[AFHTTPRequestOperation alloc] initWithRequest：request]; 
 operation.responseSerializer = [AFXMLParserResponseSerializer serializer]; 
 [操作setCompletionBlockWithSuccess：^（AFHTTPRequestOperation * operation，id responseObject）{
 if（[self.delegate respondsToSelector：@selector（myAppHTTPClientDelegate：didUpdateWithWeather :)）] {
 [self.delegate myAppHTTPClientDelegate ：self didUpdateWithWeather：responseObject]; 
} 
}失败：^（AFHTTPRequestOperation *操作，NSError *错误）{
 if（[self.delegate respondsToSelector：@selector（myAppHTTPClientDelegate：self：didFailWithError :)]）{
 [self.delegate myAppHTTPClientDelegate：self didFailWithError：error]; 
} 
}]; 
 
 [操作开始]; 
  

但我需要更改此项以使用 AFHTTPSessionManager 。

我想我需要使用它：

  [操作POST：<＃ （NSString *）＃>参数：其中＃（ID）＃> constructBodyWithBlock：<＃^（id< AFMultipartFormData> formData）block＃>成功：<＃^（NSURLSessionDataTask * task，id responseObject）成功＃>失败：<＃^（NSURLSessionDataTask *任务，NSError *错误）失败＃>] 
  

但是我不清楚应该设置什么参数？

更新

  NSDictionary * s_request = @ {@par1：[NSString stringWithFormat：@％i，par1]，@par2：par2，@par3：par3，@par4 ：[NSString stringWithFormat：@％i，par4]，@par5：par5}; 
 
 AFHTTPSessionManager * s_manager = [[AFHTTPSessionManager alloc] init]; 
 
 [s_manager POST：@http://192.168.10.26/mywebservice/myservice.asmx?op=MethodName参数：s_request成功：^（NSURLSessionDataTask * task，id responseObject）{
 NSLog（@DONE！）; 
}失败：^（NSURLSessionDataTask *任务，NSError *错误）{
 NSLog（@FAILED％@，％@，[error localizedDescription]，[error localizedFailureReason]）; 
}]; 
  

此代码始终失败。获取错误 500 。我只需要添加方法URL，或者我需要在某处添加完整的soap消息。我想念的是什么？

解决方案

您需要在Dictionary中传递参数，如下例所示：

  NSDictionary * request = @ {@email：self.email.text，@password：self.password.text}; 
 [经理POST：登录参数：请求成功：^（AFHTTPRequestOperation *操作，id responseObject）{
 NSLog（@DONE！）; 
}失败：^（AFHTTPRequestOperation *操作，NSError *错误）{
 NSLog（@登录失败：％@，operation.responseString）; 
}]; 
  

This is my current call to (asmx) SOAP web service:

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>"
     "<Save xmlns=\"http://www.myapp.com/\">"
     "<par1>%i</par1>"
     "<par2>%@</par2>"
     "<par3>%@</par3>"
     "</Save>"
     "</soap:Body>"
     "</soap:Envelope>", par1, par2, par3
     ];
NSURL *url = [NSURL URLWithString:@"http://....asmx"];
    NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];

    NSString *msgLength = [NSString stringWithFormat:@"%lu", (unsigned long)[soapMessage length]];

    [request addValue: @"text/xml; charset=utf-8" forHTTPHeaderField:@"Content-Type"];
    [request addValue: msgLength forHTTPHeaderField:@"Content-Length"];

    [request setHTTPMethod:@"POST"];
    [request setHTTPBody: [soapMessage dataUsingEncoding:NSUTF8StringEncoding]];

AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request];
operation.responseSerializer = [AFXMLParserResponseSerializer serializer];
[operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {
        if([self.delegate respondsToSelector:@selector(myAppHTTPClientDelegate:didUpdateWithWeather:)]){
            [self.delegate myAppHTTPClientDelegate:self didUpdateWithWeather:responseObject];
        }         
    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {            
        if([self.delegate respondsToSelector:@selector(myAppHTTPClientDelegate:self:didFailWithError:)]){
            [self.delegate myAppHTTPClientDelegate:self didFailWithError:error];
        }
    }];

    [operation start];

But I need to change this to use AFHTTPSessionManager.
I suppose that I need to use this:

[operation POST:<#(NSString *)#> parameters:<#(id)#> constructingBodyWithBlock:<#^(id<AFMultipartFormData> formData)block#> success:<#^(NSURLSessionDataTask *task, id responseObject)success#> failure:<#^(NSURLSessionDataTask *task, NSError *error)failure#>]

But I am not clear about what parameters should I set?

UPDATE

NSDictionary *s_request = @{@"par1": [NSString stringWithFormat:@"%i", par1], @"par2": par2, @"par3": par3, @"par4": [NSString stringWithFormat:@"%i", par4], @"par5": par5};

    AFHTTPSessionManager* s_manager = [[AFHTTPSessionManager alloc] init];

    [s_manager POST:@"http://192.168.10.26/mywebservice/myservice.asmx?op=MethodName" parameters:s_request success:^(NSURLSessionDataTask *task, id responseObject) {
        NSLog(@"DONE!");
    } failure:^(NSURLSessionDataTask *task, NSError *error) {
        NSLog(@"FAILED %@, %@", [error localizedDescription], [error localizedFailureReason]);
    }];

This code always fail. Getting error 500. Do I just need to add method URL or I need to add complete soap message somewhere. What I miss here?

解决方案

You need to pass parameter in Dictionary like in the following example:

NSDictionary *request = @{@"email": self.email.text, @"password": self.password.text};
[manager POST:login parameters:request success:^(AFHTTPRequestOperation *operation, id responseObject) {
  NSLog(@"DONE!");
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    NSLog(@"Failed to log in: %@", operation.responseString);
}];
