我尝试提交POCO库演示文稿中给出的这个简单表格,但服务器没有收到任何获取或发布请求。
HTTPClientSession s("localhost");
HTTPRequest request(HTTPRequest::HTTP_POST, "/fileupload/upload_file.php");
HTMLForm form;
form.add("entry1", "value1");
form.prepareSubmit(request);
s.sendRequest(request);
Poco::Net::HTTPResponse res;
std::istream &is = s.receiveResponse(res);
Poco::StreamCopier::copyStream(is, std::cout);
答案 0 :(得分:3)
在尝试了一下后终于得到了答案。我在prepareSubmit语句之后缺少一个form.write语句。我的最终代码就是这样发送邮件请求和文件上传请求。
HTTPRequest request(HTTPRequest::HTTP_POST, "/fileupload/upload_file.php", HTTPMessage::HTTP_1_1); HTMLForm form; form.setEncoding(HTMLForm::ENCODING_MULTIPART); form.set("entry1", "value1"); form.set("entry2", "value2"); form.addPart("file", new FilePartSource("/home/abc/Pictures/sample.png")); form.prepareSubmit(request); HTTPClientSession *httpSession = new HTTPClientSession("localhost"); httpSession->setTimeout(Poco::Timespan(20, 0)); form.write(httpSession->sendRequest(request)); Poco::Net::HTTPResponse res; std::istream &is = httpSession->receiveResponse(res); Poco::StreamCopier::copyStream(is, std::cout);
相应的上传服务器使用标准PHP代码上传HTML表单文件。
