【问题描述】：

我有这个用 python 编写的帖子请求，它工作得很好：

import requests

requests.request(
    "POST", 
     "http://locahost:8086/parse", 
     data={
        "names": ["name1", "name2"],
        "surnames": ["surname1", "surname2"]
     },
     files=[
        ("choices", ("choices-1", open("file1.txt", "rb"))),
        ("choices", ("choices-2", open("file2.txt", "rb"))),
        ("references", ("references-1", open("file3.txt", "rb"))),
        ("references", ("references-2", open("file4.txt", "rb"))),

     ] 
)

服务器应用端点写在快速API并具有以下结构：

@app.post("/test")
async def test_endpoint(
    names: List[str] = Form(...),
    surnames: List[str] = Form(...),
    references: List[UploadFile] = File(...),
    choices: List[UploadFile] = File(...)
):

我的问题是：如何使用 axios 在 Node.js 中使用此端点？

我尝试了以下内容：

const axios = require("axios");
const fs = require("fs");
const FormData = require("form-data");

const formData = new FormData();
formData.append("names", "name1");
formData.append("names", "name2");
formData.append("surnames", "surname1");
formData.append("surnames", "surname2");
formData.append("references", fs.createReadStream('file1.txt'));
formData.append("references", fs.createReadStream('file2.txt'));
formData.append("choices", fs.createReadStream('file3.txt'));
formData.append("choices", fs.createReadStream('file4.txt'));

axios.post("http://localhost:8086/parse", formData).then(response => {
    console.log(response.data);
}).catch(err => {
    console.log(err);
});

但是我遇到了 422 错误，我也尝试用 fs.readFileSync('file1.txt') 和 formData.append("names", '["name1", "name2"]') 替换 fs.createReadStream('file1.txt')，但效果不佳。有人可以帮我解决这个问题吗？

Obs：后端应该接受可变数量的names、surnames、references和choices，这就是为什么它的结构是这样的。我也在使用 axios 版本 0.21 和节点 10.19.0。

【解决方案1】：

const axios = require("axios");
const fs = require("fs");

const response = axios.request({
  method: "POST",
  url: "http://localhost:8086/parse",
  data: {
    names: ["name1", "name2"],
    surnames: ["surname1", "surname2"]
  },
  files: [
    {
      name: "choices",
      filename: "choices-1",
      file: fs.createReadStream("file1.txt")
    },
    {
      name: "choices",
      filename: "choices-2",
      file: fs.createReadStream("file2.txt")
    },
    {
      name: "references",
      filename: "references-1",
      file: fs.createReadStream("file3.txt")
    },
    {
      name: "references",
      filename: "references-2",
      file: fs.createReadStream("file4.txt")
    }
  ]
});

console.log(response.data);
