    这是一个创建于 2170 天前的主题,其中的信息可能已经有所发展或是发生改变。

    最近在看 Quasar 框架的文档,边看边用它写了一个只有登陆界面的 demo,但是写完浏览器调试时遇到了一些奇怪的问题。.vue 文件代码如下:

    <template>
        <q-layout view="hHh lpr lFr">
            <q-layout-header>
                <q-toolbar>
                    <q-btn flat dense round icon="menu" @click.native="checkStatus()"/>
                    <q-toolbar-title>登录</q-toolbar-title>
                </q-toolbar>
            </q-layout-header>
            <q-layout-drawer side="left" content-class="bg-grey-3" :content-style="{padding: '3px'}"
                             v-model="leftDrawerStatus">
                <q-list separator>
                    <q-list-header>当前用户名</q-list-header>
                    <q-item>
                        <q-item-side>
                            <q-icon name="school"/>
                        </q-item-side>
                        <q-item-main>
                            {{currentUserName}}
                        </q-item-main>
                    </q-item>
                </q-list>
            </q-layout-drawer>
            <q-page-container>
                <q-page padding class="row justify-center">
                    <q-field label="登录以获取信息" :error="loginHasError" orientation="vertical">
                        <q-input type="text" clearable autofocus suffix="@gmail.com" v-model="currentUserName"
                                 stack-label="用户名"/>
                        <q-input v-model="password" type="password" stack-label="密码"/>
                        <div class="row justify-center">
                            <q-btn label="登录" icon="info" color="secondary" outline size="md"
                                   @click="getInfo(currentUserName,password)" class="q-my-md"/>
                        </div>
                    </q-field>
                    <q-page-sticky position="bottom-right" :offset="[20,20]">
                        <q-fab color="primary" direction="up" icon="add" active-icon="close" persistent>
                            <q-fab-action
                                    color="secondary"
                                    @click="openURL('mailto:[email protected]')"
                                    icon="mail"
                            />
                            <q-fab-action

                                    @click="getInfo(currentUserName,password)"
                                    icon="cached"
                            />
                        </q-fab>

                QInput,

            },
            methods: {
                checkStatus() {
                    this.leftDrawerStatus = !this.leftDrawerStatus
                },
                openURL,
                getInfo(user, pass) {
                    fetch('http://localhost:8000/api/' + this.currentUserName + '/' + this.password, {
                        method: 'POST',
                        headers: {
                            "Content-Type": "application/json; charset=utf-8"
                        },
                        body: JSON.stringify({user, pass})
                    }).then(res => this.loginHasError = res.ok).then(response => response.json())
    
                }
            },
            data() {
                return {
                    leftDrawerStatus: false,
                    currentUserName: '',
                    password: '',
                    loginHasError: false
                };
            },
            computed: {}
        }
    
    
    </script>
    
    <style scoped>
    
    </style>
    

    问题主要有两个:

    1. <q-input>组件在 chrome 上没有 value 时会显示一个奇怪的竖线(见图 1 )
    2. <q-fab>弹出式按钮的图标显示位置有问题(见图 2 )

    图 1 Snipaste_2018-12-13_20-13-01.png

    图 2 Snipaste_2018-12-13_20-13-33.png

    问题 1 我验证过是 chrome 的问题,因为用 edge 浏览时不会出现这样的问题。我所使用的 chrome 版本为版本 72.0.3626.14 (正式版本) dev ( 64 位)

    问题 2 更加奇怪,在使用本地测试服务器npm run-script serve时图标定位异常,但在我运行npm run-script build并将编译好的文件上传到自己的服务器后再浏览就能正常显示图标。

    远程服务器环境为:

    nginx version: nginx/1.15.7
    built by gcc 6.4.0 (Alpine 6.4.0) 
    built with OpenSSL 1.1.1a  20 Nov 2018
    TLS SNI support enabled
    configure arguments: --prefix=/usr/local/nginx --with-cc-opt=-static --with-ld-opt=-static --with-threads --with-file-aio --with-http_ssl_module --with-http_v2_module --with-http_sub_module --with-http_gunzip_module --with-http_gzip_static_module --with-http_stub_status_module --with-openssl=../openssl-${OPENSSL_VER} --with-pcre=../pcre-${PCRE_VER} --with-pcre-jit --with-zlib=../zlib-${ZLIB_VER}
    

    nginx 配置如下:

    server {
        server_name ...;
        listen               443 ssl http2 reuseport fastopen=3;
        root /home/wwwroot/hexo;
        server_tokens        off;
        ssl_certificate      /etc/letsencrypt/live/.../fullchain.pem;

        ssl_session_cache          shared:SSL:50m;
        ssl_session_timeout        1d;
        ssl_session_tickets        on;
        ssl_stapling               on;
        ssl_stapling_verify        on;
        resolver                   8.8.8.8 8.8.4.4 valid=300s;
        resolver_timeout           10s;
        add_header    Strict-Transport-Security 'max-age=31536000; includeSubDomains; preload';
        index index.html;
        location / {
            expires 120s;
        }
        location ~ .*\.(gif|jpg|jpeg|png|bmp|swf|flv|ico)$ {
        expires 30d;
        access_log off;
        }
        location ~ .*\.(js|css)?$ {
        expires 7d;
        access_log off;
        }
    }
    

    请问可能是哪些方面的问题呢?问题 1 我觉得可能是 Quasar 本身的问题,问题 2 可能跟 chrome 处理本地页面中 webfont 的方式有关?谢谢!
