(PHP Extension) REST with Query ParamsSee more REST ExamplesDemonstrates how to add query params for a REST request.
<?php // The version number (9_5_0) should match version of the Chilkat extension used, omitting the micro-version number. // For example, if using Chilkat v9.5.0.48, then include as shown here: include("chilkat_9_5_0.php"); // This example requires the Chilkat API to have been previously unlocked. // See Global Unlock Sample for sample code. // Let's say we want to send a GET request to // https://example.com/search?query=hello%20world&category=books&sortBy=price&filterBy=inStock // Notice that the query parameter values must be URL encoded. // Let's also explain the parts of the above URL: // Scheme: https // The scheme specifies the protocol used to access the resource. // In this case, it is "https," which indicates that the resource is accessed using the Hypertext Transfer Protocol Secure (HTTPS). // // Host: example.com // The host part of the URL identifies the domain name or IP address of the server hosting the resource. In this case, "example.com" is the host. // // Path: /search // The path is the specific location or resource on the server that the client wants to access. // In this URL, the path is "/search," indicating that the client is requesting the "search" resource on the server. // // Query Parameters: // Query parameters are used to send additional data to the server as key-value pairs. // They are separated from the path by a question mark ? and each parameter is separated by an ampersand &. // // The above URL has four query parameters: // query=hello%20world: The "query" parameter with the value "hello world". The %20 represents the URL-encoded space character in the value. // category=books: The "category" parameter with the value "books". // sortBy=price: The "sortBy" parameter with the value "price". // filterBy=inStock: The "filterBy" parameter with the value "inStock". $rest = new CkRest(); // Connect to the REST server. // The Host part of the URL is passed in the 1st argument. // The Scheme part of the URL ("https") is indicated by the 2nd and 3rd arguments (port and bTls). $bTls = true; $port = 443; $bAutoReconnect = true; $success = $rest->Connect('example.com',$port,$bTls,$bAutoReconnect); // There are 3 ways to send the above GET request. // 1) Send the request with path and query params pre-built, where the query param values are URL encoded. $responseJson = $rest->fullRequestNoBody('GET','/search?query=hello%20world&category=books&sortBy=price&filterBy=inStock'); if ($rest->get_LastMethodSuccess() != true) { print $rest->lastErrorText() . "\n"; exit; } // 2) Pass only the Path part of the URL, and specify the query params separately by calling AddQueryParams beforehand. // Again, the query params must be already URL encoded when passed to AddQueryParams $rest->ClearAllQueryParams(); $rest->AddQueryParams('query=hello%20world&category=books&sortBy=price&filterBy=inStock'); $responseJson = $rest->fullRequestNoBody('GET','/search'); // ... // ... // 3) Pass each query parameter separately by calling AddQueryParam. In this case, the query param value should be passed without URL encoding. // (ClearAllQueryParams ensures any params set for previous request are cleared.) $rest->ClearAllQueryParams(); $rest->AddQueryParam('query','hello world'); $rest->AddQueryParam('category','books'); $rest->AddQueryParam('sortBy','price'); $rest->AddQueryParam('filterBy','inStock'); $responseJson = $rest->fullRequestNoBody('GET','/search'); // ... // ... ?> |
