uni-app提交form表单的两种方式
方式1：form表单元素较少
比如用户登录，如下图
前端代码举例
此处省略了部分多余代码
<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>后端代码举例
/**
* 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
}方式1：form表单元素较多
上面的方法在form表单元素较多时处理起来就比较费事了，一般像新增用户、商品之类的form表单少则十几个，多则几十个。如下图：
如果按照上面的写法，不仅前端写起来费事不雅观，后台接受也要一个字段一个字段的接收也煞是费劲，这个时候我们可以定义一个对象formData，将数据保存到里面提交时直接提交JSON字符串到后端，后端接收到JSON字符串后转成JSON对象，然后再进行自己的业务逻辑处理
前端代码举例：

driverTel: '', // 司机电话
idNumber: '', // 身份证号码
idNumberValidUntil:'请选择证件有效期', // 身份证有效期
idPhotoPositive: 'https://www.zzwlnet.com/files/images/upload_identity_card_front.png', // 身份证正面（个人信息面）

// 第二步

methods: {
submit: function() {
uni.request({
url: _self.server_host + '/api',
method: 'POST',
header: {'content-type' : "application/x-www-form-urlencoded"},
data: {
// 传参方式一：以JSON字符串的形式提交form表单数据
formData: JSON.stringify(_self.formData),
// 传参方式二：将form表单数据以对象形式传递
// formData: _self.formData,

success: res => {
// 服务器返回数据，后续业务逻辑处理
},
fail: () => {
uni.showToast({ title: "服务器响应失败，请稍后再试！", icon : "none"});
},
complete: () => {}
});
}
}
}
</script>后端java代码举例
// 针对传参方式一：后台以String的方式接收
public Result add(String formData){
// 将JSON字符串转换成JSONObject
JSONObject jsonObject= JSONObject.parseObject(formData);
// 继续后续业务逻辑处理
return Results.success();
}
// 针对传参方式二：后台以Object的方式接收
public Result add(Object driverObj){
// 继续后续业务逻辑处理
return Results.success();
