我无法让我的 POCO C++ 库在 Android 上发送请求,它只会抛出错误,因为找不到地址,下面是我的代码。为什么它不起作用?我一直将其用作参考,并且希望在 android 和 ios 上都可以使用。
int NetPoco::getJson(string url){
try
{
printnet("Prepare session");
// prepare session
URI uri("www.google.se");
HTTPClientSession session(uri.getHost(), uri.getPort());
// prepare path
printnet("Prepare path");
string path(uri.getPathAndQuery());
if (path.empty()) path = "/";
// send request
printnet("Prepare request for");
printnet(path.c_str());
HTTPRequest req(HTTPRequest::HTTP_GET, path, HTTPMessage::HTTP_1_1);
session.sendRequest(req);
// get response
printnet("Get response");
HTTPResponse res;
cout << res.getStatus() << " " << res.getReason() << endl;
// print response
printnet("Print response");
istream &is = session.receiveResponse(res);
StreamCopier::copyStream(is, cout);
printnet("RESULT");
}
catch (Exception &ex)
{
printnet(ex.displayText().c_str());
//cerr << ex.displayText() << endl;
return -1;
}
return 0;
}
在我的 Android 设备上运行时,我只得到:
