我有从一个字段获取文件路径的代码，并且我已将 cloudinary 与从 cloudinary 获取链接的另一图像字段集成。简而言之，我使用 multer 在数据库中保存文件路径和图像链接。因此，令我惊讶的是，一切都运行良好（或者简而言之），但数据库不断更新，除了 ObjectId 之外没有任何字段。
这是我的控制器
const fileUpload = async (req, res) => {
try {
const templateEntry = new Template();
if (req.files && req.files.length > 0) {
for (const file of req.files) {
const fileName = file.filename;
console.log("Processing file:", file.fieldname);
if (file.fieldname === "imageUrl") {
const result = await cloudinary.uploader.upload(file.path);
if (!result.secure_url) {
console.log("Cloudinary upload failed:", result);
} else {
console.log("Cloudinary upload successful. URL:", result.secure_url);
templateEntry.imageUrl = result.secure_url;
}
} else if (file.fieldname === "filePath") {
const fileEntryPath = path.join(
__dirname,
"uploads",
fileName
);
console.log("File path:", fileEntryPath); // Log the file path
templateEntry.filePath = fileEntryPath;
}
}
}
console.log("Template entry before saving:", templateEntry); // Log the template entry before saving
await templateEntry.save();
console.log("Template entry saved successfully");
res.status(200).json({
message: "Template has been saved successfully",
});
} catch (error) {
console.error("Error:", error); // Log the error for debugging
res.status(500).json({ error: error.message });
}
};
这是我的路线
const multer = require("multer");
const path = require("path");
const storage = multer.diskStorage({
destination: "./uploads",
filename: (req, file, cb) => {
const unique = Date.now() + "-" + Math.round(Math.random() * 1e9);
cb(null, unique + "-" + path.extname(file.originalname));
},
});
const upload = multer({ storage });
router.post(
"/template-upload",
upload.fields([
{ name: "filePath", maxCount: 1 },
{ name: "imageUrl", maxCount: 1 },
]),
fileUpload
);
很多改变是必要的，不确定我是否理解你的逻辑。检查这是否适合您的需求。
