首先第一次跟.net后臺(tái)配合,一個(gè)很簡(jiǎn)單的傳圖片給后臺(tái)

之前都是java后臺(tái), 要求傳圖片都是 將圖片轉(zhuǎn)String類型,然后拼接參數(shù)穿給后臺(tái),這個(gè)沒(méi)啥說(shuō)的

這次后臺(tái)要直接傳NSData類型,用了如下方法,后臺(tái)說(shuō)接收到了但是數(shù)據(jù)不對(duì),讓我去掉name,filename, mimeType這三個(gè)字段,于是繼續(xù)找別的方法:

+ (void)uploadHeadImage:(NSData *)imageData back:(void(^)(NSDictionary * dic))block
{
    NSString *headUrl = [NSString stringWithFormat:@"%@%@",CommonUrl,UploadHeadImage];
    NSDictionary *params = @{@"userId":UserInfo(User_user_id)};
    dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
        AFHTTPSessionManager *manager = [[AFHTTPSessionManager alloc]initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];
        manager.responseSerializer = [AFJSONResponseSerializer serializer];
        [manager.requestSerializer setCachePolicy:NSURLRequestReloadIgnoringLocalCacheData];
        manager.responseSerializer.acceptableContentTypes =[NSSet setWithObjects:@"text/html",@"application/json",@"image/png",nil];
        [manager POST:headUrl parameters:params constructingBodyWithBlock:^(id<AFMultipartFormData>  _Nonnull formData) {
            [formData appendPartWithFileData:imageData
                                        name:@"file"
                                    fileName:@"file.png"
                                    mimeType:@"png"];
        } progress:^(NSProgress * _Nonnull uploadProgress) {
            //            NSLog(@"%@",uploadProgress);
        } success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {
            block(responseObject);
            if (responseObject && [responseObject[@"status"] isEqualToString:@"1"]) {
                
            }else {
            }
        } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
            NSLog(@"%@", error);
        }];
    });
    
}

下面是我最后解決的方法, 在網(wǎng)上沒(méi)有找到類似的, 所以貼出來(lái),粘貼就可以用,原諒我的學(xué)藝不精

  NSString *urlStr = [NSString stringWithFormat:@"你的拼接好的URL"];
    NSLog(@"打印輸出URL===%@", urlStr);
  NSString *resultUrl = [urlStr stringByAddingPercentEncodingWithAllowedCharacters:[NSCharacterSet URLQueryAllowedCharacterSet]];
    NSURL *url = [NSURL URLWithString:resultUrl];
    
    NSMutableURLRequest *request=[NSMutableURLRequest requestWithURL:url cachePolicy:1 timeoutInterval:2.0f];
    request.HTTPMethod=@"POST";//設(shè)置請(qǐng)求方法是POST
    request.timeoutInterval=15.0;//設(shè)置請(qǐng)求超時(shí)
//    NSData *imageData = UIImagePNGRepresentation(self.photoImage);
    

    NSData *imageData = UIImageJPEGRepresentation(imageV, 0.5);
    //聲明myRequestData，用來(lái)放入http body
    NSMutableData *myRequestData=[NSMutableData data];
    
    //將image的data加入
    [myRequestData appendData:imageData];
    
    //設(shè)置HTTPHeader中Content-Type的值
    NSString *content=[[NSString alloc]initWithFormat:@"text?;"];
    
    //設(shè)置HTTPHeader
    [request setValue:content forHTTPHeaderField:@"Content-Type"];
    
    //設(shè)置Content-Length
    [request setValue:[NSString stringWithFormat:@"%lu", (unsigned long)[myRequestData length]] forHTTPHeaderField:@"Content-Length"];
    
    //設(shè)置http body
    [request setHTTPBody:myRequestData];
    
    NSURLSession *session=[NSURLSession sharedSession];
    NSURLSessionDataTask *dataTask=[session dataTaskWithRequest:request completionHandler:^(NSData * _Nullable data, NSURLResponse * _Nullable response, NSError * _Nullable error) {
        
        id result=[NSJSONSerialization JSONObjectWithData:data options:0 error:nil];
        NSLog(@"post==%@",result);
       
        
        NSString *tips = result[@"tips"];
        if ([tips isEqualToString:@"上傳成功"]) {
   
   
        }
  
    }];
