1.ASIHTTPRequest 对GET和POST请求简单封装

+(void)requestWithASIURL:(NSString *)urlString parmas:(NSMutableDictionary *)params httpMethod:(NSString *)method completeBlock:(RequestFinishBlock)block{
  //处理GET请求
  if ([[method uppercaseString] isEqualToString:@"GET"]) {
    NSArray *keys=[params allKeys];
    for (int i=0; i<keys.count; i++) {
      NSString *key=[keys objectAtIndex:i];
      NSString *values=[params valueForKey:key];
      urlString= [urlString stringByAppendingFormat:@"&%@=%@",key,values];
    }
    
  }
  NSURL *url=[NSURL URLWithString:urlString];
  ASIFormDataRequest *request=[ASIFormDataRequest requestWithURL:url];
  [request setRequestMethod:method];
  [request setTimeOutSeconds:10];
  //处理POST请求
  if ([[method uppercaseString] isEqualToString:@"POST"]) {
    NSArray *keys=[params allKeys];
    for (int i=0; i<keys.count; i++) {
      NSString *key=[keys objectAtIndex:i];
      NSString *value=[params objectForKey:key];
      if ([value isKindOfClass:[UIImage class]]) {
        //  NSString *filePath = [[NSBundle mainBundle] pathForResource:@"test4" ofType:@"gif"];
        //  NSData*  data=[NSData dataWithContentsOfFile:filePath];
        NSData *imageData=UIImageJPEGRepresentation(value, 1.0);
        [request addData:imageData forKey:key];
      }
      [request setPostValue:value forKey:key];
      
    }
  }

  [request setCompletionBlock:^{
    NSData *data=[request responseData];
    NSJSONSerialization *json=[NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableContainers error:nil];
    block(json);
  }];
  [request startAsynchronous];
  
}

2 .调用格式

NSString* urlString=@"http://192.168.1.101:8080/PengFu/jokController/getPhoneJok";
  NSMutableDictionary *params=[NSMutableDictionary dictionaryWithObject:@"1 " forKey:@"rows"];
    UIImage *image=[UIImage imageNamed:@"test3.gif"];
    [params setObject:image forKey:@"pic"];
    [params setObject:@"test gif image upload" forKey:@"status"];
    
    [DataService requestWithASIURL:urlString1 parmas:params httpMethod:@"POST" completeBlock:^(id result) {
    NSLog(@"%@",result);
    }];
