为 cool-admin(midway4.x 版)添加一个支持七牛云 KODO 的插件

该插件以预签名 token 给前台使用上传文件

安装 npm i @cool-midway/qiniu

先去后台的插件管理中,添加完相关参数（AK,SK,Region 之类的）后

在上传前先 Post 请求 dev/admin/base/comm/upload 参数 fileName 文件名 folder 文件夹

该接口返回 uploadUrl , publicUrl 以及 uploadData uploadUrl用来 PUT 请求上传 COS 所用的预签名地址 publicUrl是对应的上传后公开访问的地址,一般是和 CDN 拼起来的地址 uploadData包含了 key,token,以及 fileKey。 fileKey 是交由前台明确把上传的文件作为哪个变量名去上传使用的

另外，还需要修改一下前台工程中src\cool\modules\upload\components\index.vue:466中的相关代码

		// 重设上传请求
		async httpRequest(req) {
			const mode = await this.uploadMode();

			// 多种上传请求
			const upload = (file) => {
				let fileName = file.name;
				// 是否以 uuid 重新命名
				if (this._rename) {
					fileName = uuidv4() + "." + last((file.name || "").split("."));
				}
				return new Promise((resolve, reject) => {
					const next = (res) => {
						let headers = {};
						let updateData;
						let uploadUrl;
						let uploadMethod = "POST";
						//如果返回的数据中已经包含了uploadUrl，说明是预签名上传，就直接传文件就好了
						if (res.uploadUrl) {
							uploadUrl = res.uploadUrl;
							if(res.uploadData){
								const data = new FormData();
								for (const i in res.uploadData) {
									if (i != "fileKey") {
										data.append(i, res.uploadData[i]);
									}
								}
								data.append(res.uploadData.fileKey||"file", file);
								headers = {
									"Content-Type": "multipart/form-data"
								};
								updateData = data;

							}else{
								updateData = file;
							}
							uploadMethod = res.method || uploadMethod;
						} else {
							uploadUrl = res.host;
							const data = new FormData();
							for (const i in res) {
								if (i != "host") {
									data.append(i, res[i]);
								}
							}

							data.append("key", `app/${fileName}`);
							data.append("file", file);
							headers = {
								"Content-Type": "multipart/form-data"
							};
							updateData = data;
						}

						// 上传
						this.service.base.common
							.request({
								url: uploadUrl,
								method: uploadMethod,
								headers,
								data: updateData,
								onUploadProgress: (e) => {
									if (this.onProgress) {
										e.percent = parseInt((e.loaded / e.total) * 100);
										this.onProgress(e, req.file);
									}
								}
							})
							.then((url) => {
								if (mode === "local") {
									resolve(url);
								} else {
									//如果前边的upload接口返回里包含了publicUrl,就优先使用publicUrl
									resolve(res.publicUrl || `${res.host}/app/${fileName}`);
								}
							})
							.catch((err) => {
								reject(err);
							});
					};

					if (mode == "local") {
						next({
							host: "/upload"
						});
					} else {
						this.service.base.common
							.upload({ fileName: fileName, folder: "/upload" })
							.then((res) => {
								next(res);
							})
							.catch(reject);
					}
				});
			};

			this.loading = true;

			await upload(req.file)
				.then((url) => {
					this._onSuccess({ data: url }, { raw: req.file });
				})
				.catch((err) => {
					console.error("upload error", err);
					this.$message.error(err);

					// 	文件上传失败时的钩子
					if (this.onError) {
						this.onError(err, req.file);
					}
				});

			this.loading = false;
		},

以及src\service\request.ts:95行的相关代码，针对外站的响应处理应该忽略

// Response
axios.interceptors.response.use(
	(res: any) => {
		NProgress.done();
		const { code, data, message } = res.data;

		try {
			if (new URL(res?.config?.url).host != new URL(location.href).host) {
				return res;
			}
		} catch (err) { }

		if (!res.data) {
			return res;
		}

		switch (code) {
			case 1000:
				return data;
			default:
				return Promise.reject(message);
		}
	},
	async (error) => {
		NProgress.done();

		if (error.response) {
			const { status, config } = error.response;


			if (new URL(error.response.config.url).host != new URL(location.href).host) {
				return Promise.reject(error.message);;
			}

			switch (status) {
				case 401:
					await store.dispatch("userRemove");
					href("/login");
					break;

				case 403:
					if (isDev) {
						ElMessage.error(`${config.url} 无权限访问！！`);
					} else {
						href("/403");
					}
					break;

				case 404:
					break;

				case 500:
					if (!isDev) {
						href("/500");
					}
					break;

				case 502:
					if (isDev) {
						ElMessage.error(`${config.url} 服务异常！！`);
					} else {
						href("/502");
					}
					break;

				default:
					console.error(status, config.url);
			}
		}

		return Promise.reject(error.message);
	}
);
