Question

嗨我正在尝试使用axios在我的反应应用程序中发布多部分数据，但它不会被发布并且在花了很长时间差不多5分钟之后给我错误＆＃34;（失败了）net ::: err_CONNECTION_RESET，我不知道这里出了什么问题，下面是代码片段

制作请求的功能：

handleClick(event){
let self = this;
    if(this.state.filesToBeSent.length>0){
            const formData = new FormData();
            formData.append('file',this.state.filesToBeSent[0][0]);
            let jsonObject = new Object;
        jsonObject.itemId="1262";
        jsonObject.module="Breakfix";
        jsonObject.filename=("yyyyy");
        jsonObject.filepath="c:\\abc\\";
        jsonObject.createdOn=Math.round(new Date().getTime()/1000.0);
        jsonObject.createdBy="3";

            formData.append("attachment", JSON.stringify(jsonObject));
        let filesArray = this.state.filesToBeSent;
    axios.post(GLOBAL.uploadFile,
            formData
);
}
else{
 alert("Please upload some files first");
}
}
**code written on express to route the post to the actual API** : 
function uploadFiles(request, response) {
let payload = request.signedCookies['access_token'];
payload.apikey = "d2c-234";
const secret = 'my-secret';
const signed = jwt.sign(payload, secret, {
algorithm: 'HS256',
expiresIn: '7d'
});
let config = {
headers: {'x-auth-token': signed
}
};
let data={}
if(!_.isEmpty(request.body)) {
data = request.body;
}
axios.post("https://abc-myapp.net/serviceManagement/rest/uploadBreakfixImage/",data,config)
 .then(uploadResponse => {
    response.status(200).json(uploadResponse);
 }).catch(function(error) {
   console.error(error.stack);
 });
}
 when putting console on the express side it seems request doesn't have the payload, what am i doing wrong here ??

您无法将JSON数据与文件或任何其他附件一起发布。您可以将其作为表单数据发布到后端。表单数据作为多部分数据传递给具有相关边界的服务器。这是一个示例代码供您参考。您可以将json数据与formData一起作为键值对传递。

let data = new FormData();

data.append('itemId', '1262');
data.append('module', 'Breakfix');
data.append('filename', 'yyyyy');
data.append('filepath', 'c:\\abc\\');
data.append('upload', fileData, fileName)


axios.post(url, data)
    .then(response => console.log(response))
    .catch(errors => console.log(errors));

希望这会有所帮助。快乐的编码！
