简介

之前在写EmlogApp的时候有用到七牛云上传图片，简单记录一下

前端代码

insertImage() {
                const that = this;
                uni.chooseImage({
                    count: 1,
                    success: (res) => {
                        uni.showLoading({
                            title: '正在上传...'
                        });
                        uni.uploadFile({
                            url: '域名',
                            filePath: res.tempFilePaths[0],
                            name: 'file',
                            method:'POST',
                            fileType:"image",
                            formData: {
                                ak: ,//七牛云ak
                                sk: ,//七牛云sk
                                kj: ,//七牛云空间名
                                //ym: ,七牛绑定的域名，这个直接在PHP代码中修改
                            },
                            success: function(res) {
                                var data = JSON.parse(res.data)
                                console.log(data.data)
                                that.editorCtx.insertImage({
                                    src: data.data,
                                    alt: data.data,
                                    success: function() {
                                        that.cover.push(data.data)
                                        that.messageToggle('success', '上传成功');
                                        uni.hideLoading();
                                    }
                                })
                            },
                            fail: function() {
                                that.messageToggle('error', '上传失败');
                                uni.hideLoading();
                            }
                        })
                    }
                })
            },

PHP代码

    // 七牛云上传
    public function img(Request $request){
        $file = request() -> file('file'); //接收前端数据
        $filePath = $file-> getRealPath();//要上传图片的本地路径

        $ext = (md5(time()));//上传到七牛后保存的文件名
        $accessKey = $_POST['ak'];
        $secretKey = $_POST['sk'];
        $auth = new Auth($accessKey, $secretKey);//构建鉴权对象

        // $bucket = "hkiii";//要上传的空间
        $bucket = $_POST['kj'];
        //初始化UploadManager对象并进行文件的上传
        $uploadMgr = new UploadManager();          
        $token = $auth->uploadToken($bucket); //生成上传Token
        list($ret, $error) = $uploadMgr->putFile($token, $ext, $filePath);
        if ($ret) {
            return json(['code' => 200, 'msg' => '上传成功', 'data' => 'https://cdn.hkiii.cn/'.$ret['key']]);
        }
        }
