Question

我正在尝试创建一个博客网站，但我仍然坚持创建单个“帖子”视图页面。当我从href获取/发布/ id页面时一切正常但当我手动刷新页面或共享链接时，我得到这样的页面：

{"_id":"56fa7443c1542bdc3bdb3857","user":{"_id":"56fa6b0cc83017643c50c5ad",

已经坚持了几天，我该如何解决这个问题？

快递代码（./app/backend/routes/post.js）

router.get('/:id', function (req, res) {
    Model.findById(req.params.id, function(err, post){
        return res.status(200).send(post);
    })
    .populate('user');
});

Angular PostCtrl代码（./app/frontend/js/controller/post.js）

$http.get('/post/'+$routeParams.id).success(function (post) {
    post.text = $sce.trustAsHtml(post.text);
    $scope.post = post;

}).error(function (error, status) {
    $scope.errorMessage = error + ' (code:' + status + ')';
});

路线（./app/frontend/js/app.js）

$routeProvider
.when('/', {
  templateUrl: 'views/main.html',
  controller: 'MainCtrl'
})
.when('/post/:id', {
  templateUrl: 'views/post.html',
  controller: 'PostCtrl'
})

我修好了。我必须将Angular路由从.when('/blog/:id'更改为/blog/:id，并将href更改为/post/:id。

似乎角度和快速路由不能相同。 Express似乎仍然将数据发送到/blog/:id，而angular从那里获取数据并立即将其显示给/post/:id。刷新页面后，一切似乎都正常。只需要立即隐藏/post/:id中的敏感数据，或找到用户可以访问/**********ASSING A PROTOCOL TO A SOCKET (BIND)************/ if(bind(sock_dest, (struct sockaddr *)&server,sizeof (server))<0) { printf("Bind failed\n"); return 1; } /**********************************************************/ /*************** LISTEN FOR CONNECTIONS ********************/ listen(sock_dest,6); printf("Waiting for connections\n"); /**********************************************************/ /****ACCEPT CONNECTION AND MAKE ATHREAD FOR EVERY CLIENT***/ c = sizeof ( struct sockaddr_in); pthread_t thread_id; pthread_attr_t attr; pthread_attr_init(&attr); pthread_attr_setdetachstate(&attr,PTHREAD_CREATE_DETACHED); while( ( client_socket = accept( sock_dest, ( struct sockaddr *)&client, (socklen_t *) &c)) ) { printf("Connection accepted.\n"); if(client_socket < 0) { printf("Accepting connection failed.\n"); return 1; } if(pthread_create( &thread_id, &attr, connection_handler, (void*) &client_socket ) < 0) { printf("Couldn't create a thread for the new client.\n"); return 1; } else printf("Handler assigned\n"); } return 0; } void *connection_handler (void *socket_dest) { char *dest_file_name; char buffer[300]; int sock = *( int *) socket_dest; char *exit_signal="EXIT"; if((dest_file_name=create_random_name())==NULL) { printf("Generating a random name failed\n"); return NULL; } int i=0; while(1) { while(i<299) { recv(sock,buffer+i,1,0); if(buffer[i]=='\n') { i=0; // setting i to 0 because next time when we read a path(string) it need to be stored from 0 pozition in array. break; } ++i; } if((strcmp(buffer,exit_signal))==0) { printf("Exit signal received.\n"); return NULL; } if((write_line_in_file(buffer,dest_file_name))==1) { printf("Failed to write one of the lines in %s\n",dest_file_name); } printf("Linie primita:%s\n",buffer); bzero(buffer,256); // put all bytes to 0 from buffer } return 0; } char *create_random_name(void) { const char charset[] = "abcdefghijklmnopqrstuvwxyz"; char *file_name; int i=0; int key; struct stat stbuf; time_t t; while(1) { srand((unsigned) time(&t)); if((file_name = malloc(16 * sizeof ( char )) ) == NULL) { printf("Failed to alloc memory space\n"); return NULL; } strcpy(file_name,"__ft_"); for(i=5 ; i<11 ; i++) { key = rand() % (int)(sizeof(charset)-1); file_name[i]=charset[key]; } strcat(file_name,".txt"); file_name[15] = '\0'; if(stat(file_name,&stbuf)==-1) { break; } } return file_name; } /************* RETURN 0 IF SUCCES AND 1 IF FAILS ***********/ int write_line_in_file(char *line,char *file_name) { FILE *file; if((file=fopen(file_name, "a")) == NULL) { printf("Can't open %s.\n"); return 1; } fprintf(file,"%s",line); fclose(file); return 0; }的方式。

我正在尝试理解您的代码，这就是我能想到的

// this is how the route should be using populate
router.get('/post/:id', function (req, res) {
  Model.findOne({_id: req.params.id}).populate('user').exec(function (error, post) { 
    if (post) {
      res.status(200).json(post);
    } else {  
      // handle error here...
    }
  })
});

其他一切看起来还不错。

我希望这会有所帮助。
