如何在单个请求中将文本和图像数据上载到服务器Objective c++

// 创建请求URL
NSURL *url = [NSURL URLWithString:@"http://example.com/upload"];

// 创建请求体数据
NSMutableData *bodyData = [NSMutableData data];

// 添加文本数据
NSString *textData = @"Hello, World!";
[bodyData appendData:[textData dataUsingEncoding:NSUTF8StringEncoding]];

// 添加图像数据
UIImage *image = [UIImage imageNamed:@"image.jpg"];
NSData *imageData = UIImageJPEGRepresentation(image, 1.0);
[bodyData appendData:imageData];

// 创建请求对象
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
[request setHTTPMethod:@"POST"];

// 设置请求体的Content-Type
NSString *boundary = @"Boundary-7MA4YWxkTLLu0UIW"; // 自定义边界字符串
NSString *contentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@", boundary];
[request setValue:contentType forHTTPHeaderField:@"Content-Type"];

// 设置请求体
[request setHTTPBody:bodyData];

// 发送请求
NSURLSessionDataTask *task = [[NSURLSession sharedSession] dataTaskWithRequest:request completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
    // 处理响应
    if (error) {
        NSLog(@"Error: %@", error);
    } else {
        NSLog(@"Response: %@", response);
        NSLog(@"Data: %@", [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding]);
    }
}];
[task resume];
