uniapp app外包开发要求接口地址是可以动态修改的,首先需要一个页面，用来配置接口地址和端口。

页面代码

<template>
	<view class="set-page">
		<view class="set-cell">
			<view class="set-cell_hd">服务器信息</view>
			<view class="set-row flex-center">
				<view class="flex_bd">
					<view class="url">http://{{ip}} <text v-if="port">:{{port}}</text>{{pageUrl}}</view>
				</view>
				<view class="btn-test" @click="testLink">点击测试网络</view>
			</view>
		</view>
		<view class="set-cell">
			<view class="set-cell_hd">IP地址</view>
			<view class="set-row">
				<u-input v-model="ip" input-align="center" :clearable="false" />
			</view>
		</view>
		<view class="set-cell">
			<view class="set-cell_hd">端口</view>
			<view class="set-row ">
				<u-input v-model="port" input-align="center" :clearable="false" />
			</view>
		</view>
		<!-- 		<view class="set-cell">
			<view class="set-cell_hd">URL</view>
			<view class="set-row ">
				<u-input v-model="pageUrl" input-align="center" :clearable="false" />
			</view>
		</view> -->
		<view class="form-footer">
			<u-button throttleTime='200' @click="submit" type="primary">提交</u-button>
		</view>
	</view>
</template>

<script>
	export default {
		data() {
			return {
				ip: '',
				port: '',
				pageUrl: '',
			}
		},
		onLoad() {
			if (uni.getStorageSync('ip')) {
				this.ip = uni.getStorageSync('ip')
			}
			if (uni.getStorageSync('port')) {
				this.port = uni.getStorageSync('port')
			}
		},
		methods: {
			testLink() {
				var url = 'http://' + this.ip + ':' + this.port + '/api/Comnon/Login'
				uni.request({
					url: url,
					method: "post",
					data: {},
					success: (res) => {
						uni.showToast({
							title: '测试连接成功',
							icon: 'none'
						})
					},
					fail: (res) => {
						uni.showToast({
							title: '测试连接失败',
							icon: 'none'
						})
					}

				})
			},
			submit() {
				uni.setStorageSync('ip', this.ip)
				uni.setStorageSync('port', this.port)
				uni.showToast({
					title: '设置成功',
					icon: 'none'
				})
			}
		}
	}
</script>

<style lang="scss">
	.set-page {
		padding: 60rpx 30rpx;
	}

	.set-cell {
		margin-bottom: 44rpx;

		.set-cell_hd {
			line-height: 1;
			font-weight: bold;
			font-size: 14px;
			line-height: 20px;
			color: #000000;
			margin-bottom: 24rpx;
		}
	}

	.set-row {
		/deep/ .u-input {
			height: 38px;
			background: #F4F6FA;
			border-radius: 8px;
			color: #646A73;
			padding: 0 15px !important;
		}
	}

	.set-group-row {
		/deep/ .u-input {
			flex: unset;
			width: 62px;
			padding: 0 !important;
			margin-right: 10px;
		}
	}

	.form-footer {
		padding-top: 60px;
	}

	.btn-test {
		width: 98px;
		height: 26px;
		background: #F4F6FA;
		font-size: 12px;
		line-height: 26px;
		color: #4876FF;
		text-align: center;
		border-radius: 8px;
	}
</style>

接口配置

其次是设置默认地址和端口，以及如果能够获取到缓存的地址和端口的话，则将地址和端口设置为缓存的地址和端口。

var ip = '默认ip'
var port = '默认端口'
if (uni.getStorageSync('ip')) {
	ip = uni.getStorageSync('ip')
}
if (uni.getStorageSync('port')) {
	port = uni.getStorageSync('port')
}
var url = 'http://' + ip + ':' + port
var configs = {
	baseUrl: url,
	baseUrl2: url,
	throttleTime: 3000,
	debounceTime: 500,
	uploadImage: url + '/api/Command/UpLoadImg',
	upload2: url + '/api/common/upload'
}

export default configs
