我可以上传照片的邮递员，和在招摇。 我需要设置@{@"Content-Type":@"multipart/form-data"}在头。 但在OC程序，这是一些错误。 帮助！
NSString *urlString =@"http://192.168.1.1/upload";
UIImage *image = [UIImage imageNamed:@"camp.jpg"];
NSData *imageData = UIImageJPEGRepresentation(image, 1.0);
NSLog(@"上传图片的样子：%@", imageData);
NSDictionary *parameters = @{@"file":@"camp.jpg"};
AFHTTPSessionManager *manager1 = [AFHTTPSessionManager manager];
manager1.requestSerializer = [AFJSONRequestSerializer serializer]; // 请求JSON格式
manager1.responseSerializer = [AFJSONResponseSerializer serializer]; // 响应JSON格式
manager1.responseSerializer.acceptableContentTypes = [NSSet setWithObjects:@"application/json;charset=UTF-8", nil];
[manager1员额：urlString参数：参数的标题：@{@"Content-Type":@"multipart/form-data"}constructingBodyWithBlock:^(id_Nonnull formData){
[formData appendPartWithFileData:imageData name:@"file" fileName:@"camp.jpg" mimeType:@"image/jpeg"];
} progress:nil success:^(NSURLSessionDataTask * _Nonnull task, id _Nullable responseObject) {
NSLog(@"上传成功：%@", responseObject);
} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
NSLog(@"上传失败：%@", error);
}];
和错误是：
