Use Onvif protocol to obtain device snapshot in LiveNVR security streaming service_onvif windows c++ obtain snapshot
class=”markdown_views prism-atom-one-dark”> We know that snapshot information can be obtained from LiveNVR. The previous article also explained how LiveNVR captures snapshots. Here we use another method to capture snapshots Process Get device capabilitiesCapabilities Acquire the capabilities of the device, and can obtain the URI of Media and PTZ. Using the URI of Media, you can capture snapshots _tds__GetCapabilities* capabilities = soap_new__tds__GetCapabilities(proxyDevice, -1); tt__CapabilityCategory* category = new tt__CapabilityCategory; capabilities->Category = category; *(capabilities->Category) = tt__CapabilityCategory__All; _tds__GetCapabilitiesResponse* response = soap_new__tds__GetCapabilitiesResponse(proxyDevice, -1); if (SOAP_OK == proxyDevice->GetCapabilities(capabilities, response)) { if (response->Capabilities) { //Media URI: response->Capabilities->Media->XAddr; //PTZ URI: response->Capabilities->PTZ->XAddr; } } Get Media Profile Get Profile token to get the corresponding snapshot _trt__GetProfiles* getProfiles = soap_new__trt__GetProfiles(proxyMedia, -1); _trt__GetProfilesResponse* response = soap_new__trt__GetProfilesResponse(proxyMedia, -1); if (SOAP_OK == proxyMedia->GetProfiles(getProfiles, response)) { int size = response->__sizeProfiles; for (int i = 0; i Profiles[i]) { //Media Profile Token: response->Profiles[i]->token; //General equipment contains multiple Profile Tokens, including main code stream, sub-code stream, and third code stream. } } } Get snapshot access address The snapshot access address is usually an HTTP address, and the snapshot file can be GET through this HTTP address MediaBindingProxy* mediaProxy = new MediaBindingProxy; mediaProxy->soap_endpoint = mediaUrl.c_str(); if (!security(mediaProxy, username, password)) { delete mediaProxy; return result; } _trt__GetSnapshotUri*…
PHP web crawler practice: crawl Baidu search results and analyze the data structure_php statistics based on search results
Baidu’s search engine has an anti-crawler mechanism. I will try guzzle first. The code is as follows: true]); $ql = $client->request(‘GET’, ‘https://www.baidu.com’, [ ‘cookies’ => $jar ]); if($ql->getStatusCode()!=200){ echo ‘The website status is abnormal’;die; } echo $ql->getBody(); PHP Copy Baidu intercepted it directly and entered the jump page. I will try to add a browser header file and try again. The modified header is as follows: $ql = $client->request(‘GET’, ‘https://www.baidu.com’, [ ‘cookies’ => $jar, ‘headers’ => [ ‘Accept-Encoding’ => ‘gzip, deflate, br’, ‘Accept’ => ‘text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8’, ‘Accept-Language’ => ‘zh-CN,zh;q=0.9,en;q=0.8’, ‘Cache-Control’ => ‘no-cache’, ‘Connection’ => ‘keep-alive’, ‘User-Agent’ => ‘Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/69.0.3497.100 Safari/537.36’, ] ]); PHP Copy I tested it and the website opened. We continued, entered keywords, and searched, and found that it was intercepted by security, so I felt that I couldn’t do it directly with GuzzleHttp, so I continued with my artifacts: jaeger/querylist and jaeger/querylist-puppeteer. Installation steps: 1. Install dependencies Before this, you must enable the proc_open function of PHP, otherwise the complete installation will not be possible composer install jaeger/querylist composer install jaeger/querylist-puppeteer 2. Install nodejs yum install nodejs 3.Install npm 4. Install @nesk/puphpeteer npm install @nesk/puphpeteer 5.PHP enables proc_open The code…
Tree level-order traversal
class=”markdown_views prism-atom-one-dark”> The reason why I suddenly thought of writing this is that there was a hierarchical traversal of an n-ary tree in the daily question in April, and I was actually not skilled at doing it. I also thought that I had written about the level-order traversal of a binary tree before, so I thought of summarizing several topics together. It can be regarded as deepening the impression. There are four tree traversal methods: Pre-order traversal, in-order traversal, post-order traversal, and level-order traversal. The order in the first three methods refers to the traversal order of the root node, which is generally implemented using recursion (depth-first traversal). Layer-order traversal means starting from the top layer and traversing layer by layer from left to right, instead of left first then right or first right then left. The ideas of level-order traversal and breadth-first search are similar. To maintain a queue, first put the root node into the queue. When the node is dequeued, its child nodes are put into the queue. However, there will be no obvious layering, but only one array, so we also need to record the number of nodes in each layer to facilitate layering. Question 1:…
Does installing web.py_web.py in python 3.x support the python3.x version?
class=”markdown_views prism-atom-one-dark”> Install web.py in python 3.x Recently decided to move from python2.7 to 3.x. When using the database, I still chose web.py, which I was more interested in before. But there seemed to be various problems during installation. ImportError: No module named ‘utils’ ModuleNotFoundError: No module named ‘db’ Wait, it seems that no new solution has been found. Finally decided to try the dev version. pip install web.py==0.40.dev0 Finally found that the dev version of web.py works perfectly on python 3.x. I personally tested python 3.6 The code is as follows: import pymysql pymysql.install_as_MySQLdb() import web db = web.database(dbn=’mysql’, host=’db_host’, port=3306, user=’root’, pw=’password’, db=’db_name’, charset=’utf8′) results = db.query(‘select * from user where id = 1;’) for user in results: print(user.name) print(user.id_no) I hope this article can help students who are struggling to find web.py available on python 3.x.
