Integrating Core Code

Introduce the required JavaScript framework. In the following example, the jQuery component needs to be introduced. The reference version is jQuery 3.4.1. If the co-browsing function is required, introduce the cobrowse.js and cobrowseCommon.js components or release the cobrowse plugin for use. (For details about the development of the plugin, see section 3.1 "Guide to the Development and Usage of the cobrowse Plugin.") Introduce the cobrowse.js and cobrowseCommon.js components in CDN mode. Replace ip:port with the IP address and port number of the CEC, or directly with the domain name of theCEC, for example, https://www.test.com/service-cloud/resource.root/cobrowse/sdk/cobrowse.js. Figure 1 shows an example of the code.

Figure 1 JavaScript framework reference example

1. Co-browsing operations cannot be performed on a new tab page.

2. When the cobrowse.js and cobrowseCommon.js components for co-browsing are introduced and the third-party page contains nested iFrames, co-browsing operations can be performed only in the iFrame where the JavaScript components are introduced. If an iFrame has a parent iFrame, co-browsing operations cannot be performed in the parent iFrame.
Generate the authorization signature on the server by following the instructions provided in Developing an Authorization Signature Generation Mechanism.

On the frontend of the enterprise system, send an Ajax request to obtain the authorization signature generated on the server.

function testAjax() {
     let timestamp = new Date().getTime();
     let serviceUrl = "authorizationService";
     let thirdUserData = {};
     thirdUserData['thirdUserName'] = userName;
     thirdUserData['thirdUserId'] = userId;
     thirdUserData['tenantSpaceId'] = tenantSpaceId; 
     thirdUserData['channelConfigId'] = configId;
     thirdUserData['locale'] = locale;
     thirdUserData['mapService'] = tencent; 
     thirdUserData['timestamp'] = timestamp;
     var request = $.ajax({
         url: serviceUrl,
         method: "POST",
         contentType: "application/json",
         data: JSON.stringify(thirdUserData),
     });
     request.done(function(message){
         if(message){
             thirdUserData['thirdPartAuthorization'] = message;
             thirdValidate(thirdUserData);
         }
         return  message;
     });

After obtaining the signature, use the Ajax to request the JavaScript script to be integrated.

const $ContextPath = "https://ip:port/service-cloud"; 
function thirdValidate(thirdUserData) {
  let timestamp = new Date().getTime();
  let serviceUrl = $ContextPath + "/webclient/chat_client/js/newThirdPartyClient.js?"+"&t=" + timestamp;
      var request = $.ajax({ 
         url: serviceUrl,
         method: "POST",
         data: JSON.stringify( ),
         crossDomain: true,
         dataType:"text",
         xhrFields: {withCredentials: true},
         error: function (XMLHttpRequest, textStatus, errorThrown)
              { console.log(XMLHttpRequest.status); console.log(XMLHttpRequest.readyState); console.log(textStatus); },
         success: function (data) {
             importScript(data)
         }    
});
