ios - EWS GetStreamingEvents. Response is received only by timeout -
in ios app i'm trying streaming events ews following this manual. first subscribe notifications, receive subscription id , perform getstreamingevents request. subscription process successful, getting streaming events not. receive response timeout. yes, contain notifications, no problems expect receive response once event has occurred not when request time up.
so launched charles , examined traffic of mac mail app. can see receives 1 response right after making getstreamingevents request , receives responses every time event has occurred expected. made xml mac mail app's still no luck.
this subscribe xml:
<?xml version="1.0" encoding="utf-8"?> <soap:envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:t="http://schemas.microsoft.com/exchange/services/2006/types"> <soap:header> <t:requestedserverversion version="exchange2010_sp2" /> </soap:header> <soap:body> <m:subscribe xmlns:m="http://schemas.microsoft.com/exchange/services/2006/messages"> <m:streamingsubscriptionrequest subscribetoallfolders="true"> <t:eventtypes> <t:eventtype>copiedevent</t:eventtype> <t:eventtype>createdevent</t:eventtype> <t:eventtype>deletedevent</t:eventtype> <t:eventtype>modifiedevent</t:eventtype> <t:eventtype>movedevent</t:eventtype> <t:eventtype>newmailevent</t:eventtype> <t:eventtype>freebusychangedevent</t:eventtype> </t:eventtypes> </m:streamingsubscriptionrequest> </m:subscribe> </soap:body> </soap:envelope> and getstreamingevents xml:

update:
this how build subscription:
bcstring subscriberequestmessage::buildsoaprequest() const { xml_document<> doc; xml_node<>* decl = doc.allocate_node(node_declaration); decl->append_attribute(doc.allocate_attribute("version", "1.0")); decl->append_attribute(doc.allocate_attribute("encoding", "utf-8")); doc.append_node(decl); // envelope xml_node<>* envelope = doc.allocate_node(node_element, "soap:envelope"); envelope->append_attribute(doc.allocate_attribute("xmlns:soap", "http://schemas.xmlsoap.org/soap/envelope/")); envelope->append_attribute(doc.allocate_attribute("xmlns:t", "http://schemas.microsoft.com/exchange/services/2006/types")); doc.append_node(envelope); { // header xml_node<>* header = doc.allocate_node(node_element, "soap:header"); { xml_node<>* reqserverversion = doc.allocate_node(node_element, "t:requestedserverversion"); xml_attribute<>* serverversionattribute = doc.allocate_attribute("version", m_requestedserverversion.c_str()); reqserverversion->append_attribute(serverversionattribute); header->append_node(reqserverversion); } envelope->append_node(header); // body xml_node<>* body = doc.allocate_node(node_element, "soap:body"); { xml_node<>* subscribe = doc.allocate_node(node_element, "m:subscribe"); { subscribe->append_attribute(doc.allocate_attribute("xmlns:m", "http://schemas.microsoft.com/exchange/services/2006/messages")); xml_node<>* streamingsubscriptionrequest = doc.allocate_node(node_element, "m:streamingsubscriptionrequest"); { if (m_folderids.size() > 0) { xml_node<>* folderids = doc.allocate_node(node_element, "t:folderids"); { (const bcstring& folderid : m_folderids) { xml_node<>* folderidnode = doc.allocate_node(node_element, "t:folderid"); folderidnode->append_attribute(doc.allocate_attribute("id", folderid.c_str())); folderids->append_node(folderidnode); } } streamingsubscriptionrequest->append_node(folderids); } else { xml_attribute<>* subscribetoall = doc.allocate_attribute("subscribetoallfolders", "true"); streamingsubscriptionrequest->append_attribute(subscribetoall); } xml_node<>* eventtypes = doc.allocate_node(node_element, "t:eventtypes"); { (const bcstring& eventtype : m_eventtypes) { xml_node<>* eventtypenode = doc.allocate_node(node_element, "t:eventtype"); xml_node<>* eventtypevaluenode = doc.allocate_node(node_data, "", eventtype.c_str()); eventtypenode->append_node(eventtypevaluenode); eventtypes->append_node(eventtypenode); } } streamingsubscriptionrequest->append_node(eventtypes); } subscribe->append_node(streamingsubscriptionrequest); } body->append_node(subscribe); } envelope->append_node(body); } bcstring retval; print(std::back_inserter(retval), doc, print_no_indenting); return retval; } and how build streaming xml:

i ran problem once, don't know if same you. using ews on http chunked transfer encoding , received responses @ timeout. turned out terminating 0 chunk sent @ timeout, not after each response, therefore waiting more data until timeout.
note not bad have low timeout since might want use multiple subscriptions in single getevents request , can't add or remove subscriptions running getevents request.
