This time I will show you how the WeChat applet can upload picturesto the server. What are theprecautionsfor the WeChat applet to upload pictures to the server. The following is a practical case. Let’s take a look.

-wxml     /**选择图片 */ choose: function () { var that = this wx.chooseImage({ count: 1, sizeType: ['original', 'compressed'], // 可以指定是原图还是压缩图，默认二者都有 sourceType: ['album', 'camera'], // 可以指定来源是相册还是相机，默认二者都有 success: function (res) { var tempFilePaths = res.tempFilePaths that.setData({ tempFilePaths: res.tempFilePaths }) console.log(res.tempFilePaths) wx.setStorage({ key: "card", data: tempFilePaths[0] }) } }) },

2. Use wx.uploadFile to upload the image just uploaded to the server

formSubmit2: function (e) { var that = this var card = wx.getStorageSync('card') wx.uploadFile({ url: app.globalData.create_funds, filePath: card, name: 'card', formData: { 'user_id': app.globalData.user_id, 'person': e.detail.value.person, 'company': e.detail.value.company, }, success: function (res) { console.log(res) } }) } } },

1. Key points
