如何在Multipart superagent请求中发送对象以及附加文件？ [英] How do I send an Object along with an attached File in a Multipart superagent request?

问题描述

我正在尝试使用superagent向我的API发出多部分POST请求。

I am trying to make a multipart POST request to my API using superagent.

我的代码：

superagent
  .post(apiUrl + '/api/company/profile/edit')
  .field("profileData", profileData)
  .attach('company_logo', logoFile )
  .set('Accept', 'application/json')
  .end(function(err, res){
    if(err){
      dispatch(updateProfileStatusAction("error", res));
    } else {
      dispatch(updateProfileStatusAction("success", res));
    }
  });

我遇到的问题是 profileData 是嵌套的对象。当我在API中收到请求时，我看到 profileData 的值为字符串 [Object，Object]

The problem I am having is that profileData is an object that is nested. When I get the request in the API I see the value of profileData as the string [Object, Object]

当我查看带有superagent的多部分请求的文档 .field（）只是键，值对而不是对象。然后我尝试使用.send（{profileData：profileData}）而不是字段，但是当我这样做时，我得到一个错误，说.attach和.send不能在同一个请求中一起使用。

When I look at the documentation for multipart request with superagent https://visionmedia.github.io/superagent/#multipart-requests it appears like the .field() is meant to be just a key, value pair rather then an object. I then tried to use .send({profileData: profileData}) instead of field, but when I do that I get an error saying that .attach and .send can not be used together in the same request.

推荐答案

我认为使用 JSON.stringify（）将JS_Object转换为一个JSON字符串。

I think it should be enough to use JSON.stringify() to convert the JS_Object to a JSON string.

superagent
 .post(apiUrl + '/api/company/profile/edit')
 .field("profileData", JSON.stringify(profileData))
 .attach('company_logo', logoFile )
 ...
