所以我使用Axios将文件从一台服务器发送到另一台服务器,一个是应用程序后端,另一个是区块链服务器。
我将文件发送到哪里:
router.post("/acme/:id", auth, async (req, res) => {
var formData = new FormData();
console.log(req.files.file)
formData.append("image", req.files.file.data);
var Response;
try {
Response = await axios.post(BC_SERVER + "acmeDataFileUpload", {
id: req.params.id,
data: formData,
headers: {
'Content-Type': 'multipart/form-data'
}
});
} catch (error) {
console.log("Error BlockChain");
}
try {
res.status(201).send("ok");
} catch (e) {
res.status(500).send(e);
}
});
Axios 发送它的位置:
app.post('/acmeDataFileUpload', async (req, res) => {
const id_owner = req.body.id;
console.log(req.body)
const file = req.body.data;
const fileName = id_owner;
const filePath = 'files/' + fileName;
console.log(fileName);
file.mv(filePath, async (err) => {
try {
const fileHash = await addFile(fileName, filePath);
fs.unlink(filePath, (err) => {
if (err) console.log(err);
});
const json = '{"dataType": "Object" , "local": "'+localServer+fileHash+'",' +'"ipfsServer": "'+ipfsServer+fileHash+'"}';
console.log(json);
const obj = JSON.parse(json);
res.status(201).send(obj);
} catch (err) {
console.log('Error : failed to download file');
console.log(err);
return res.status(500).send(err);
}
});
});
基本上我在这里发送缓冲区,因为FormData不接受文件并告诉我source.on不是一个函数,我宁愿我的图像被发送到而不是,Axios真的让我感到困惑。req.filesreq.body
