C++；RESTSDK POST表单数据json < C++ > REST SDK（卡萨布兰卡）是否可以发布“表单数据”？我有一个给定的web服务，它在“表单数据”中查找post数据，而不是在正文中 这是C++代码： http_client client(L"http://localhost/posttest/jsontest.php"); // Manually build up an HTTP request with header and request URI. http_request request(methods::POST); request.headers().add(L"Content-Type", L"application/json"); request.headers().add(L"Content-Length", L"100"); request.headers().add(L"Host", L"example.com"); request.headers().add(L"X-Requested-With", L"XMLHttpRequest"); request.set_body(obj); return client.request(request).then([id](http_response response) { if (response.status_code() == status_codes::OK) { return response.extract_json(); } else { /* Print bad status code */ wcout << L"Server returned returned status code " << response.status_code() << L'.' << std::endl; } return pplx::task_from_result(json::value()); })

（这只是一个PHP代码示例，我用于测试）

就是这样：

utility::string_t Lreq = L"code=" + Lcode;

http_client client(L"http://localhost/posttest/jsontest.php");

// Manually build up an HTTP request with header and request URI.

http_request request(methods::POST);
request.headers().add(L"Content-Type", L"application/x-www-form-urlencoded; charset=UTF-8");
request.headers().add(L"Content-Length", L"100");
request.headers().add(L"Host", L"testhost.com");
request.headers().add(L"X-Requested-With", L"XMLHttpRequest");
request.set_body(Lreq);

utility::string_t Lreq = L"code=" + Lcode;

http_client client(L"http://localhost/posttest/jsontest.php");

// Manually build up an HTTP request with header and request URI.

http_request request(methods::POST);
request.headers().add(L"Content-Type", L"application/x-www-form-urlencoded; charset=UTF-8");
request.headers().add(L"Content-Length", L"100");
request.headers().add(L"Host", L"testhost.com");
request.headers().add(L"X-Requested-With", L"XMLHttpRequest");
request.set_body(Lreq);
