1.在pages创建一个main文件夹 
2.在main文件夹下创建一个miain.js文件。 
添加代码：

1. const constant = require('../../utils/constant.js')
2. const app = getApp()
3. const recorderManager = wx.getRecorderManager()
4. const innerAudioContext = wx.createInnerAudioContext()
5.  
6. Page({
7. data:{
8. money:"0.00",
9. userInfo: {},
10. hasUserInfo: false,
11. canIUse: wx.canIUse('button.open-type.getUserInfo'),
12. },
13. onLoad: function () {
14. if (app.globalData.userInfo) {
15. this.setData({
16. userInfo: app.globalData.userInfo,
17. hasUserInfo: true
18. })
19. } else if (this.data.canIUse){
20. // 由于 getUserInfo 是网络请求，可能会在 Page.onLoad 之后才返回
21. // 所以此处加入 callback 以防止这种情况
22. app.userInfoReadyCallback = res => {
23.  
24. this.setData({
25. userInfo: res.userInfo,
26. hasUserInfo: true
27. })
28. }
29. } else {
30. // 在没有 open-type=getUserInfo 版本的兼容处理
31. wx.getUserInfo({
32. success: res => {
33. app.globalData.userInfo = res.userInfo
34. this.setData({
35. userInfo: res.userInfo,
36. hasUserInfo: true
37. })
38. }
39. })
40. }
41. },
42. getlocat:function(){
43. wx.authorize({
44. scope: 'scope.record',
45. success() {
46. // 用户已经同意小程序使用录音功能，后续调用 wx.startRecord 接口不会弹窗询问
47. const options = {
48. duration: 600000,
49. sampleRate: 44100,
50. numberOfChannels: 1,
51. encodeBitRate: 192000,
52. format: 'mp3',
53. frameSize: 50
54. }
55.  
56.  
57. recorderManager.start(options)
58.  
59. recorderManager.onStart(() => {
60. console.log('recorder start')
61. })
62. recorderManager.onError((res) => {
63. console.log(res);
64. })
65. }
66. })
67. // console.log(app)
68. },
69.  
70. strop:function(){
71. recorderManager.stop()
72. recorderManager.onStop((res) => {
73. console.log('recorder stop', res)
74. const { tempFilePath } = res
75. console.log(tempFilePath)
76. this.tempFilePath = tempFilePath
77. })
78. },
79. //播放声音
80. play: function () {
81. innerAudioContext.autoplay = true
82. innerAudioContext.src = this.tempFilePath;
83. innerAudioContext.onPlay(() => {
84. console.log('开始播放')
85. })
86. innerAudioContext.onError((res) => {
87. console.log(res.errMsg)
88. console.log(res.errCode)
89. })
90.  
91. },
92. })

3.新建一个main.wxml文件  添加代码如下

1. <view>
2. <button bindtap='getlocat'>测试</button>
3. <button bindtap='strop'>测sss试</button>
4. <button bindtap="play" >播放录音</button>
5. </view>
