Wt :: WFileUpload文件太大

我想让用户上传多个大型的XML和文本文件进行进一步处理，但WFileUpload不允许超过128kb的任何东西，我无法找出一种方法来重写默认设置。在Xubuntu 16.04上安装wt 3.3.6。使用Firefox中的大多数默认设置访问0.0.0.0:8080处的wthttp服务器。Wt :: WFileUpload文件太大

我已经调查了file_dialog可执行--help设置，发现选项--max内存请求大小，但改变这似乎并没有帮助。我还编辑了/etc/wt/wt_config.xml以将最大内存请求大小更改为高于128kb的值，也无济于事。基于输出文件“file_dialog-output.txt”，我可以成功上传60kb文件，但2Mb文件失败。

我建立和运行，如.HPP文件指出下面的代码：

file_dialog.hpp

//Compile 
//g++ file_dialog.cpp -o file_dialog -lwt -lwthttp 
//Run 
//./file_dialog --docroot . --http-address 0.0.0.0 --http-port 8080 

//headers 
#include <Wt/WApplication> 
#include <Wt/WContainerWidget> 
#include <Wt/WFileUpload> 
#include <Wt/WPushButton> 
#include <Wt/WBreak> 

//FileApplication class definition, derived from WApplication 
class FileApplication : public Wt::WApplication 
{ 
    public: 
     FileApplication(const Wt::WEnvironment & env); 
     Wt::WContainerWidget * file_upload_dialog_container_widget; 
     Wt::WFileUpload * file_upload; 
     Wt::WPushButton * file_output_button; 
     std::ofstream fout; 
     void tooLargeBytes(long long int byte_size_1); 
     void warningFileTooLarge(void); 
     void infoFileUploaded(void); 
};

file_dialog.cpp

#include "file_dialog.hpp" 

//FileApplication constructer class; returns root with widget 
FileApplication::FileApplication(const Wt::WEnvironment& env) 
: Wt::WApplication(env) 
{ 
    setTitle("File Generation"); 

    this->requestTooLarge().connect(this, &FileApplication::tooLargeBytes); 

    Wt::WContainerWidget * upload_dialog_container_widget = new Wt::WContainerWidget(root()); 
    Wt::WFileUpload * file_upload = new Wt::WFileUpload(upload_dialog_container_widget); 
    file_upload->setMultiple(true); 
    new Wt::WBreak(upload_dialog_container_widget); 
    Wt::WPushButton * file_output_button = new Wt::WPushButton(upload_dialog_container_widget); 
    file_output_button->setText("Upload"); 

    file_upload->fileTooLarge().connect(this, &FileApplication::warningFileTooLarge); 
    file_upload->uploaded().connect(this, &FileApplication::infoFileUploaded); 
    file_output_button->clicked().connect(file_upload, &Wt::WFileUpload::upload); 
    file_output_button->clicked().connect(file_output_button, &Wt::WPushButton::disable); 
} 

//Application - File too large 
void FileApplication::tooLargeBytes(long long int byte_size_1) 
{ 
    std::ofstream fout ("file_dialog-output.txt"); 
    fout << "byte_size_1"; 
    fout << byte_size_1; 
    fout.close(); 
} 

//File too large 
void FileApplication::warningFileTooLarge(void) 
{ 
    std::ofstream fout ("file_dialog-output.txt"); 
    fout << "File too large"; 
    fout.close(); 
} 

//File successfully uploaded 
void FileApplication::infoFileUploaded(void) 
{ 
    std::ofstream fout ("file_dialog-output.txt"); 
    fout << "File uploaded"; 
    fout.close(); 
} 

//Application constructor function 
Wt::WApplication * createApplication(const Wt::WEnvironment& env) 
{ 
    return new FileApplication(env); 
} 

//Main function 
int main(int argc, char ** argv) 
{ 
    return Wt::WRun(argc, argv, &createApplication); 
}

任何帮助，非常感谢！
