如何使用AFNetworking上传大容量文件

// 导入AFNetworking库
#import <AFNetworking/AFNetworking.h>

// 创建AFHTTPSessionManager对象
AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];

// 设置请求参数
NSString *urlString = @"http://example.com/upload";
NSDictionary *parameters = @{@"key": @"value"};

// 创建上传任务
[manager POST:urlString parameters:parameters constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
    // 将要上传的文件添加到请求体中
    NSURL *fileURL = [NSURL fileURLWithPath:@"path/to/file"];
    [formData appendPartWithFileURL:fileURL name:@"file" error:nil];
} progress:^(NSProgress *uploadProgress) {
    // 监听上传进度
    NSLog(@"Upload Progress: %@", uploadProgress);
} success:^(NSURLSessionDataTask *task, id responseObject) {
    // 处理上传成功的回调
    NSLog(@"Upload Success: %@", responseObject);
} failure:^(NSURLSessionDataTask *task, NSError *error) {
    // 处理上传失败的回调
    NSLog(@"Upload Failure: %@", error);
}];
