xcode - iOS端想用ASIHttpRequest上传一个文件，却一直传不上去

Question

想用ASIHttpRequest上传一个.stl的文件，几十K到70M之间的文件，用的下面这段代码
[uploadFile removeObjectAtIndex:0];//删除mac文件下的默认的.DS_Store

        NSString *upFilePath = [NSString stringWithFormat:@"%@/%@",filePath,uploadFile[0]];//上传的文件全路径
        ASIFormDataRequest *request=[ASIFormDataRequest requestWithURL:[NSURL URLWithString:@"xxxxx"]];
        [request setRequestMethod:@"Post"];
        [request addRequestHeader:DownLoad_TOKEN value:@"X-Auth-Token"];
        [request setFile:filePath  forKey:@"file"];
        [request setDelegate:self];
        [request startAsynchronous];
        

然后试了很多次我去看自己上传的空间没有东西，并且我也不知道哪个代理可以监视文件是否已经开始上传或或者伤处啊能成功与否，求大神解救！！！

最後我每使用ASIHttpRequest，用NSURLSessionDataTask建立連結發送請求了。

//上传文件方法
- (void)uploadFile
{
    
    
    // 要上传的文件的文件名
    NSString *folder = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject];
    NSString *fileName = [folder stringByAppendingPathComponent:@"update测试/deer_head_reshaped-v3.6.0.STL"];
    NSLog(@"Post filename is %@", fileName);
    
    
    // 接收文件上传的地址
    NSString *urlString = @"http://test.3dker.cn/api/upload/uploadp";
    
    // 服务器端上传表单项的名称，一定与服务器端接收文件的名一致
    NSString *uploadInputFieldName = @"file";

    // 要传递的POST的参数，其中file对应上传文件的文件名
    NSDictionary *params = @{
                             uploadInputFieldName: fileName,
                             @"key1": @"Value1"                 // 其他要POST传递的参数
                             };
    
    
    
    
    /*********************以上按需要修改，下面的代码为固定代码，一般不需要修改*************************/
    
    
    //分界线的标识符
    NSString *TWITTERFON_FORM_BOUNDARY = @"AaB03x";
    //根据url初始化request
    NSMutableURLRequest* request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:urlString]
                                                           cachePolicy:NSURLRequestReloadIgnoringLocalCacheData
                                                       timeoutInterval:10];
    //设置登陆用户的X-Auth-Token
    [request setValue:DownLoad_TOKEN forHTTPHeaderField:@"X-Auth-Token"];//若无则不需要
    //分界线 --AaB03x

    NSString *imageFileName = [params objectForKey:uploadInputFieldName];
    
    //得到图片的data
    NSData* data = [NSData dataWithContentsOfFile:imageFileName];
    
    //http body的字符串
    NSMutableString *body=[[NSMutableString alloc]init];
    //参数的集合的所有key的集合
    NSArray *keys= [params allKeys];
    
    //遍历keys
    for(int i=0;i<[keys count];i++)
    {
        //得到当前key
        NSString *key=[keys objectAtIndex:i];
        //如果key不是pic，说明value是字符类型，比如name：Boris
        if(![key isEqualToString:uploadInputFieldName])
        {
            //添加分界线，换行
            [body appendFormat:@"%@\r\n",MPboundary];

    NSMutableData *myRequestData=[NSMutableData data];
    //将body字符串转化为UTF8格式的二进制
    [myRequestData appendData:[body dataUsingEncoding:NSUTF8StringEncoding]];
    //将上传文件的data加入
    [myRequestData appendData:data];
    //加入结束符--AaB03x--

你是上傳一張圖片給的麼？ 為什麼不去試試AFNetWorking? 以前培訓學習的時候用過ASI上傳不過好像沒你這麼複雜。下面是我上傳頭像外帶參數的程式碼，你可以看看（AFNetwork寫的。。不過應該差不多把。）

+(void)postAddActive:(NSString *)url : (NSMutableDictionary *) params: (NSData *) imageData: (void (^)(id t)) success{

    AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
    [manager.requestSerializer setTimeoutInterval:45];
    [SVProgressHUD showWithStatus:@"请稍等上传中..."];

    
    
    [manager POST:url  parameters:params constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
        
       
       // NSData *data = UIImageJPEGRepresentation(imageTo, 0.7);
        if(imageData !=nil){
        
          [formData appendPartWithFileData:imageData name:[NSString stringWithFormat:@"file"] fileName:[NSString stringWithFormat:@"UploadeFile.png"] mimeType:@"image/png"];
        }

        
        
    } success:^(AFHTTPRequestOperation *operation,id responseObject) {
        
        success(responseObject);
       [SVProgressHUD showSuccessWithStatus:@"上传成功"];
        [SVProgressHUD dismiss];
        
        
    } failure:^(AFHTTPRequestOperation *operation,NSError *error) {
        if (![operation isCancelled]) {
            [SVProgressHUD showErrorWithStatus:@"上传失败"];
            [SVProgressHUD dismiss];
        }
    }];
    

}

ASIHttpRequest已經停止更新維護了，建議使用AF
