stringToBuffer(text) { let enc = new TextEncoder(); console.log("enc", enc.encode(text)); return enc.encode(text); }, concatenate(...arrays) { let length = 0; for (let i = 0; i < arrays.length; i++) { arrays[i] = new Uint8Array(arrays[i]) //全部转成Uint8Array length += arrays[i].length; } let result = new Uint8Array(length); let offset = 0; for (let array of arrays) { result.set(array, offset); offset += array.length; } return result.buffer; }, y应该是stringToBuffer
wx.getFileSystemManager().readFile在开发者工具有效 在微信无效?if (this.data.imageUrls.length > 0) { this.data.imageUrls.forEach((element) => { console.log(element.url, '单图片') wx.getFileSystemManager().readFile({ filePath: element.url, success(res) { let boundary = "----abcdefg"; let boundarystart = that.stringToBuffer(`--${boundary}\r\n`); let boundaryend = that.stringToBuffer(`\r\n--${boundary}--\r\n`); let fileheader = that.stringToBuffer(`Content-Disposition: form-data; name="files";filename="123.jpg";\r\nContent-Type:image/jpeg;\r\n\r\n`); let buffers = that.concatenate(boundarystart, fileheader, res.data, boundaryend); wx.request({ data: buffers, url: 'https://www.baolegebei.com/api/lygim/upload_images', header: { 'Authorization': wx.getStorageSync(cache.token), 'content-type': `multipart/form-data; boundary=${boundary}` }, method: 'post', success(res) { if (res.data.success) { // console.log('上传成功', res.data.data[0]) let imgs = that.data.imgs; imgs.push(res.data.data[0]) that.setData({ imgs }, () => { console.log(that.data.imgs) }) } else { wx.showToast({ title: '有非法图片,禁止上传', icon: 'error', duration: 2000 }) } }, fail(error) { console.log(error); wx.showToast({ title: '上传失败', icon: 'error', duration: 2000 }) } }) }, fail(error) {} }); }) } b背景: 小程序图片需要校验才能上线,wx.getFileSystemManager().readFile读取图片信息,后台校验。 w为什么读取在开发者工具 跟 微信小程序环境不一致呢, r如下截图 [图片][图片] 两种环境下, 图片读取的url不太一样, wx.getFileSystemManager().readFile貌似好像只能读取http://tmp/yGi0tYkuQcq8400b11db0f30e52a74b8da68f34ad42c.jpg, 不能读取 wxfile://tpm_2e23rewfwefdfvdf 这种类型图片地址 望大佬指点,谢谢
