I modified the example project hello_world,also couldn't use
request().get(string const&) method correctly.
void my_hello_world::main(std::string /*url*/)
{
cppcms::http::request & r = request();
std::string str = r.get("ok");
response().out()<<
"<html>\n"
"<body>\n"
" <h1>Hello World</h1>\n"
"</body>\n"
"</html>\n";
}
Got some error messages:
/usr/local/src/cppcms-0.99.10/examples/hello_world $ make
g++ -O2 -Wall -g hello.cpp -o hello -lcppcms -lbooster
hello.cpp: In member function ‘virtual void
my_hello_world::main(std::string)’:
hello.cpp:19:21: error: invalid use of incomplete type ‘struct
cppcms::http::request’
/usr/local/include/cppcms/application.h:52:9: error: forward declaration of

hello.cpp:19:14: warning: unused variable ‘str’ [-Wunused-variable]

I figured out the real reason. We have one old cppcms version installed in our computer.After removed them,everything is OK. 陈抒 Best regards http://blog.csdn.net/sheismylife On Sat, Sep 10, 2011 at 2:02 PM, 刘怀宇 <mys...@gm...> wrote: > Hello Artyom , I try JSON_RPC over JSONP by the sample you proposed! > > cppcms::http::request& r = request(); > string name = "method"; > r.get(name); > > But I met a serious error. > > > > > 2011/9/9 <cpp...@li...> > >> Send Cppcms-users mailing list submissions to >> cpp...@li... >> >> To subscribe or unsubscribe via the World Wide Web, visit >> https://lists.sourceforge.net/lists/listinfo/cppcms-users >> or, via email, send a message with subject or body 'help' to >> cpp...@li... >> >> You can reach the person managing the list at >> cpp...@li... >> >> When replying, please edit your Subject line so it is more specific >> than "Re: Contents of Cppcms-users digest..." >> >> >> Today's Topics: >> >> 1.

親愛的 刘怀宇, If you are going to participate in this list's discussion, I think it would be helpful to everyone if you did not subscribe to the daily digest. Your email subject lines "Cppcms-users Digest, Vol 26, Issue 11" does not help future readers going through the archives in deciding what the content of the email would be. Please, subscribe to receive individual mails. Also, you don't need to include the whole daily digest in your email. Snip appropriately the emails you reply to in order to keep a small citation that would be enough to give some context to your email. Thankfully, Artyom takes the extra trouble or replying to you by redacting a new email with an appropriate subject line. I trust your English is good enough to understand what I wrote. If you have troubles understanding, let me know and I'll translate it all in Chinese. 謝謝你的合作。 Blessings, Augustin. |
