微信小程序服务器开小差了,微信小程序wx.request请求封装
微信小程序 wx.request
RequestTask wx.request(Object object)發(fā)起 HTTPS 網(wǎng)絡(luò)請求。
示例代碼
wx.request({
url: 'test.php', //僅為示例，并非真實的接口地址
data: {
x: '',
y: ''
},
header: {
'content-type': 'application/json' // 默認(rèn)值
},
success (res) {
console.log(res.data)
}
})
wx.request 不進(jìn)行二次封裝確實不太好用 分享下我這邊wx.request的封裝
api.js
const app = getApp()
const request = (url, options) => {
return new Promise((resolve, reject) => {
wx.request({
url: `${app.globalData.host}${url}`,
method: options.method,
data: options.data,
header: {
'Content-Type': 'application/json; charset=UTF-8',
'Authorization': app.globalData.accessToken
},
timeout: 10000,
success(request) {
if (request.statusCode === 200) {
resolve(request.data)
} else if (request.statusCode === 401) {
wx.navigateTo({
url: '/pages/login/login'
})
reject(request.data)
} else if (request.statusCode === 500) {
wx.showModal({
title: '系統(tǒng)錯誤',
content: request.data.errmsg,
})
reject(request.data)
} else {
reject(request.data)
}
},
fail(error) {
wx.showModal({
title: '系統(tǒng)錯誤',
content: '服務(wù)器正在開小差',
})
reject(error.data)
},
complete: function (res) {}
})
})
}
// 把需要Loading的方法進(jìn)行封裝，減少不必要代碼
const requestWithLoading = (url, options) => {
return new Promise((resolve, reject) => {
wx.showLoading({
title: '加載中',
})
wx.request({
url: `${app.globalData.host}${url}`,
method: options.method,
data: options.data,
header: {
'Content-Type': 'application/json; charset=UTF-8',
'Authorization': app.globalData.accessToken
},
timeout: 10000,
success(request) {
if (request.statusCode === 200) {
resolve(request.data)
} else if (request.statusCode === 401) {
wx.navigateTo({
url: '/pages/login/login'
})
reject(request.data)
} else if (request.statusCode === 500) {
wx.showModal({
title: '系統(tǒng)錯誤',
content: request.data.errmsg,
})
reject(request.data)
} else {
reject(request.data)
}
},
fail(error) {
wx.showModal({
title: '系統(tǒng)錯誤',
content: '服務(wù)器正在開小差',
})
reject(error.data)
},
complete: function (res) {
wx.hideLoading()
}
})
})
}
const get = (url, options = {}) => {
return request(url, {
method: 'GET',
data: options
})
}
const getWithLoading = (url, options = {}) => {
return requestWithLoading(url, {
method: 'GET',
data: options
})
}
const post = (url, options) => {
return request(url, {
method: 'POST',
data: options
})
}
const postWithLoading = (url, options) => {
return requestWithLoading(url, {
method: 'POST',
data: options
})
}
const put = (url, options) => {
return request(url, {
method: 'PUT',
data: options
})
}
const putWithLoading = (url, options) => {
return requestWithLoading(url, {
method: 'PUT',
data: options
})
}
// 不能聲明DELETE(關(guān)鍵字)
const remove = (url, options) => {
return request(url, {
method: 'DELETE',
data: options
})
}
const removeWithLoading = (url, options) => {
return requestWithLoading(url, {
method: 'DELETE',
data: options
})
}
module.exports = {
get,
getWithLoading,
post,
postWithLoading,
put,
putWithLoading,
remove,
removeWithLoading
}
使用方式
const api = require('../../api/api')
Page()前引入
api.post(login, {
data: ''
}).then(res => {
if(){}
}).catch(err => {
wx.showToast({
title: err.message,
icon: 'none'
})
})
data 參數(shù)說明
最終發(fā)送給服務(wù)器的數(shù)據(jù)是 String 類型，如果傳入的 data 不是 String 類型，會被轉(zhuǎn)換成 String 。轉(zhuǎn)換規(guī)則如下：
對于 GET 方法的數(shù)據(jù)，會將數(shù)據(jù)轉(zhuǎn)換成 query string(encodeURIComponent(k)=encodeURIComponent(v)&encodeURIComponent(k)=encodeURIComponent(v)…)
對于 POST 方法且 header[‘content-type’] 為 application/json 的數(shù)據(jù)，會對數(shù)據(jù)進(jìn)行 JSON 序列化
對于 POST 方法且 header[‘content-type’] 為 application/x-www-form-urlencoded 的數(shù)據(jù)，會將數(shù)據(jù)轉(zhuǎn)換成 query string (encodeURIComponent(k)=encodeURIComponent(v)&encodeURIComponent(k)=encodeURIComponent(v)…)
總結(jié)
