wx.request是小程序客户端与服务器端交互的接口
HTTPS 请求
一个微信小程序,只能同时(同时不能大于5个)有5个网络请求
发起网络请求
url
data
header
method
dataType
wx.request({
url: 'test.php', //仅为示例,并非真实的接口地址
data: {
x: '' ,
y: ''
},
header: {
'content-type': 'application/json' // 默认值
},
success: function(res) {
console.log(res.data)
}
})
四种网络请求:
(wx.request)
(wx.uploadFile)
(wx.downloadFile)
(wx.connectSocket)
var request = {
url: '',
data: {},
method: '',
success: function (res) {
},
fail: function () {
},
complete: function () {
}
}
wx.openSetting 来跳转到设置授权界面
/* index.js */
// 若有用户信息存在则继续
Page({
onLoad () {
wx.getStorage({
key: 'userinfo',
success: (res) => {
this.setUserinfo(res)
},
fail: (res) => {
api.login().then((res) => {
this.setUserinfo(res)
}).catch(e => {
if (e.errMsg && e.errMsg === 'getUserInfo:fail auth deny') {
this.setData({
isauth: false
})
}
})
}
})
},
toSetting() {
wx.openSetting({
success: (res) => {
this.setData({
isauth: res.authSetting['scope.userInfo']
})
if (res.authSetting['scope.userInfo']) {
api.login().then((res) => {
this.setUserinfo(res)
})
}
}
})
}
})
// setUserinfo 就是对用户信息做一下处理 不具体展开了
/* index.wxml */
<view class="unauth" wx:if="{{!isauth}}">
<image class="unauth-img" src="../../images/auth.png"></image>
<text class="unauth-text">检查到您没打开授权</text>
<button class="color-button unauth-button" bindtap="toSetting">去设置</button>
</view>
<view class="container" wx:else>
...
</view>
function queryRequest(data){
wx.request({
url:"https://example.com/api/",
data:data,
header:{
// "Content-Type":"application/json"
},
success:function(res){
console.log(res.data)
},
fail:function(err){
console.log(err)
}
})
}
服务器设置:
// Content-type为multipart/form-data
function uploadFile(file,data) {
wx.uploadFile({
url: 'http://example.com/upload',
filePath: file,
name: 'file',
formData:data,
success:function(res){
console.log(res.data)
},
fail:function(err){
console.log(err)
}
})
}
function downloadFile(url,typ,success){
wx.downloadFile({
url:url,
type:type,
success:function(res){
if(success){
success(res.tempFilePath)
}
},
fail:function(err){
console.log(err)
}
})
}
function svaeFile(tempFile,success){
wx.saveFile({
tempFilePath:tempFile,
success:function(res){
var svaedFile=res.savedFilePath
if(success){
success(svaeFile)
}
}
})
}
