字符串格式错误

尝试了各种字符串格式，但未找到结果

msg.body = '''Dear admin, 

         You requested that your password be reset.
         Please visit the link below or copy and paste it into your browser to create a new password.%s''' \
                   %url_for('.get_resetpassword',token=token,_external=True)%'''

        Thank you,

builtins.TypeError TypeError：不是所有在格式化字符串期间转换的参数

Answer 1

稍后应使用字符串格式：

            for(int i=0;i<ja.length();i++){
                String proj_id = ja.getJSONObject(i).getString("project_id");

                Set<Object> sets = new HashSet<>(); 
                if (!(sets.contains(proj_id))) {
                   sets.add(proj_id);                       
                }                   

                Iterator<Object> itr=sets.iterator();  

                while(itr.hasNext())  {                                 
                    JSONArray jarr=new JSONArray();
                     for (int j=0;j<sets.size();j++) {
                         System.out.println("i="+i);
                         System.out.println("j="+j);

                        List emplist=empservice.getEmpByProjId(proj_id);
                        JSONObject finalobj=new JSONObject();           

                        finalobj.put("project_id", proj_id);  
                        finalobj.put("emp-proj", emplist);
                        jarr.put(finalobj);

                        itr.next();
                      } 
                    jsonObject.put("data", jarr);
                    System.out.println("list of jarr obj : "+jarr);         
                }

            }                                                                                       //for

因此您无需打扰任何事情。

或使用：

msg.body = '''Dear admin, 

         You requested that your password be reset.
         Please visit the link below or copy and paste it into your browser to create a new password.%s  

        Thank you,

        '''%url_for('.get_resetpassword',token=token,_external=True)

Answer 2

这可能有效。

url_for="YOUR INPUT"
a='''Dear admin, 

     You requested that your password be reset.
     Please visit the link below or copy and paste it into your browser to create a new password.%s

     Thank you,
     Team.'''% (url_for)
