这是我的代码:
string line;
ifstream toOpen;
toOpen.open("allfiles.txt", ios::in);
int fileCounter=0;
if(toOpen.is_open()){
while(!toOpen.eof()){
getline(toOpen,line);
string dl = "wget -q -E -O superman/" + href[0] + " " + line;
//cout << dl << endl;
fileCounter++;
system(dl);
}
toOpen.close();
}
其中allfiles.txt(内容):
http://www.xxx.com/index1.html
http://www.xxx.com/index2.html
href []的值类似于:{index1.html,index2.html,index3.html ...}
我的错误讯息:
file.cpp:XX: error: cannot convert ‘std::string’ to ‘const char*’ for argument ‘1’ to ‘int system(const char*)’
最佳答案
函数'system'接受'const char *'作为参数,但是您给了它一个std :: string。尝试
system(dl.c_str());
