Bagaimana untuk menyerahkan borang dalam apl uni? Artikel berikut akan berkongsi dengan anda dua cara untuk menyerahkan borang dalam aplikasi uni. Saya harap ia akan membantu anda!
Kaedah 1: Elemen borang ialah lebih kecil Kurang
Sebagai contoh, log masuk pengguna, seperti yang ditunjukkan di bawah
Contoh kod bahagian hadapan
Ini Beberapa kod berlebihan telah ditinggalkan
<template> <view style="padding:50rpx;"> <view style="margin-top:60rpx;"> <form @submit="submit"> <view class="gui-border-b gui-form-item" style="margin-top:80rpx;"> <view class="gui-form-body"> <input type="number" class="gui-form-input" v-model="driverTel" name="driverTel" placeholder="手机号" placeholder-style="color:#CACED0"/> </view> </view> <view class="gui-border-b gui-form-item" style="margin-top:30rpx;"> <view class="gui-form-body"> <input type="password" class="gui-form-input" v-if="isPwd" v-model="password" name="password" placeholder="密码" placeholder-style="color:#CACED0"/> <input type="text" class="gui-form-input" v-if="!isPwd" :disabled="true" v-model="password" name="password" placeholder="密码" placeholder-style="color:#CACED0"/> </view> <text class="gui-form-icon gui-icons gui-text-center" @click="changePwdType" :style="{color:isPwd?'#999999':'#008AFF'}"></text> </view> <view style="margin-top:50rpx;"> <button type="default" class="gui-button gui-bg-blue msgBtn" formType="submit" style="border-radius:50rpx;"> <text class="gui-color-white gui-button-text-max">登录</text> </button> </view> </form> </view> </view> </template> <script> uni.request({ url: _self.server_host + "/app/driver/login/password", method:'POST', header:{'content-type' : "application/x-www-form-urlencoded"}, data:{ // 对于上面的form表单提交,我们可以直接在uni.request的data属性中直接提交就行了 driverTel: _self.driverTel, password: _self.password }, success: (res) => { // 服务器返回结果 } }) </script>
Contoh kod belakang
/** * 这里可以以一个实体类来接收,实体类必须包含前端传参参数的对应字段 */ @PostMapping("/password") public Result loginByPassword(LoginUserVO loginUserVO) { // 处理业务逻辑 } /** * 也可以按照字段名来接收 */ @PostMapping("/password") public Result loginByPassword(String username, String passsword) { // 处理业务逻辑 }
Kaedah 1: bentuk Terdapat banyak unsur bentuk
Kaedah di atas lebih menyusahkan untuk diproses apabila terdapat banyak unsur bentuk Secara umumnya, terdapat sekurang-kurangnya sedozen bentuk bentuk seperti menambah pengguna dan produk baru sebanyak berpuluh-puluh. Seperti yang ditunjukkan di bawah:
Jika anda mengikuti kaedah penulisan di atas, bukan sahaja bahagian hadapannya menyusahkan dan tidak sedap dipandang, malah penerimaan latar belakang juga memerlukan penerimaan medan demi medan pada masa ini , kita boleh mentakrifkan objek formData
, simpan data di dalamnya dan serahkan rentetan JSON terus ke hujung belakang apabila menyerahkan rentetan JSON dan menukarnya menjadi objek JSON, dan kemudian melaksanakan pemprosesan logik perniagaannya sendiri <.>
Contoh kod hadapan:
