angular - 在 qt webview 中使用 mailto

Question

• Mailto 在所有浏览器中工作，但在 qtwebview 中无法打开默认邮件客户端

如果我直接在 html 中使用 mailto 链接，它工作正常，但在链接中添加正文和主题不起作用前发送电子邮件
这是代码

 mailpopup(){
             const userAgent = window.navigator.userAgent;
             alert(userAgent);
             if(this.model.firstName == undefined || this.model.firstName == null){
               this.model.firstName  = 'No comments';
               alert(this.model.firstName);
             }
             else{
               this.model.firstName;
               alert(this.model.firstName);
             }
           
             if(this.model.firstName2 == undefined || this.model.firstName2 == null){
               this.model.firstName2  = 'name@exp.com';
               alert(this.model.firstName2);
             }
             else{
               this.model.firstName2;
               alert(this.model.firstName2);
             }
             var maillen = JSON.parse(sessionStorage.getItem('log Data'));
             if (maillen.length > 1) {
               if (environment.production == false) {
                 var  a
                 if(userAgent.includes('Firefox/')){
                   a = maillen.slice(-7);
                 }
                 else{
                 a = maillen.slice(-2);
                 }
                 
               }
               else {
                 if(userAgent.includes('Firefox/')){
                   a = maillen.slice(-10);
                 }
                 else{
                 a = maillen.slice(-2);
                 }
               }
               var testmail = JSON.stringify(a);
               alert(testmail);
             }
             var bodyText = 'userAgent Details: ' + userAgent + '%0D%0A' + "Device Details: " + localStorage.getItem('devicedetails') + '%0D%0A' + 'User Comments: ' + this.model.firstName + '%0D%0A' +'%0D%0A' + [testmail.replace(/\},/g, "%0D%0A")];
             const text = `mailto:${this.model.firstName2}?&subject=Error
   Logs&body=${bodyText}`
             alert(text);
             var mail = document.createElement("a");
             mail.href = text;
             mail.target = "_self"
             mail.click();
           }
