wx.compressImage的压缩问题，及电脑开发工具，跟安卓手机不一样等问题？
我发现用这个wx.compressImage方法来压缩jpg文件有很大的问题。
问题一，用‘微信开发者工具’（下面简称：电脑）跟手机‘开发版’上传同一张图片。压缩后的体积不一样。这里用了一张 1.47 MB= 1537177 Byte大小的图片。电脑上传的是
手机上传得到的是：
明显的看得出区别非常大，，，，，
还有一个问题，就是手机上传，用了压缩方法的比原来的图片还大！！
原来！264.01 KB= 270350 Byte
压缩后！296.56 KB= 303678 Byte
我很不解。。。。。
代码在这里：
//增加图片 选项图片
addImageTap(e) {
let that = this
let tempFiles = this.data.tempFiles
wx.chooseMedia({
count: 9,
sizeType: ['original', 'compressed'],
sourceType: ['album'],
success(res) {
console.log(res)
if (res.type == "video") {
wx.showToast({
title: '目前暂不支持上传视频。',
icon: 'none',
duration: 3000
})
return
}
console.log(res.tempFiles[0].tempFilePath)
wx.getImageInfo({
src: res.tempFiles[0].tempFilePath,
success(res) {
console.log(res,'1111')
}
})
that.uploadingImage(res.tempFiles[0].tempFilePath)//上传到云存储
wx.compressImage({
src: res.tempFiles[0].tempFilePath, // 图片路径
quality: 0, // 压缩质量
success(res) {
console.log(res)
that.uploadingImage(res.tempFilePath)
wx.getImageInfo({
src: res.tempFilePath,
success(res) {
console.log(res,'2222')
}
})
}
})
let arr = tempFiles.concat(res.tempFiles)
that.setData({
tempFiles: arr
})
}
})
},
备注：我手机有点原图，为了严谨。原图跟压缩图，我都一起上传到云存储，所以不存在数据不对的问题。。。

I found that with this Wx Compressimage method to compress JPG files has a big problem. Question 1: upload the same picture with the "wechat developer tool" (hereinafter referred to as "computer") and the "development version" of the mobile phone. The volume after compression is different. Here is a picture with the size of 1.47 MB = 1537177 bytes. What the computer uploads is from the mobile phone, and what you get is: obviously, there is a big difference. Another problem is that the mobile phone uploads, which uses the compression method, is larger than the original picture!! original! 264.01 KB = 270350 bytes after compression! 296.56 KB = 303678 byte I don't understand..... Here is the code: / / add the picture option picture addimagetap (E) {let that = this let tempfiles = this.data.tempfiles wx.choosemedia ({count: 9, sizetype: ['original ','compressed'], sourcetype: ['album '], success (RES) {console.log (RES) if (res.type = = "video") {wx.showtoast ({Title:' uploading video is not supported at present ', Icon:' none ', duration: 3000}) return} console log(res.tempFiles[0].tempFilePath) wx. getImageInfo({ src: res.tempFiles[0].tempFilePath, success(res) { console.log(res,'1111') } }) that. Uploadingimage (res.tempfiles [0]. Tempfilepath) / / upload to cloud storage Wx Compressimage ({SRC: res.tempfiles [0]. Tempfilepath, / / image path quality: 0, / / compression quality success (RES) {console.log (RES) that.uploadingimage (res.tempfilepath) wx.getimageinfo ({SRC: res.tempfilepath, success (RES) {console.log (RES, '2222')})}}) let arr = tempfiles concat(res.tempFiles) that. SetData ({tempfiles: arr})}}). Note: my mobile phone is a little original, for the sake of preciseness. The original image and compressed image are uploaded to cloud storage together, so there is no problem of wrong data... Byte
而且我还发现，用电脑压缩后的地址没有后缀。。。
