我在几个地方都看到过这样的问题，但是没有一个解决方案对我有用。我正在尝试使用nodeJs打一个api。
我必须传递两个名为image和data的文件：
let image =
{value: fs.createReadStream('tempdata/imageFile.jpg'),
options:
{filename: 'tempdata/imageFile.jpg',
contentType: null}};
const data =
{value: fs.createReadStream('tempdata/dataFile.json'),
options: {filename: 'tempdata/dataFile.json', contentType: null}};
let options = {
payload,
headers: {
'If-Match': '*',
'cache-control': 'no-cache',
'content-type': 'multipart/form-data; boundary=---------------------------13335242989826'
},
formData:
{
image: image,
data: data
}
};
return imageUploadClient.post(suffix, options).then((mutates) => {
request.log('Mutates is ', mutates);
})
.catch((err) => {
err.message = `ImageUploadService: ${err.message} - ${suffix}.`;
throw err;
});
这是我在将这些文件作为输入的java api中遇到的错误：

我正在传递边界值，我缺少什么吗？
可以正常运行的邮递员请求是：
var fs = require("fs");
var request = require("request");
var options = { method: 'POST',
url: 'http://localhost:10080/imageUpload',
headers:
{ 'postman-token': '73fae1f6-7829-ff79-1c8e-990e7c29875b',
'cache-control': 'no-cache',
'content-type': 'multipart/form-data; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW' },
formData:
{ file:
{ value: 'fs.createReadStream("/Users/df/Downloads/182753163.jpg")',
options:
{ filename: '/Users/df/Downloads/182753163.jpg',
contentType: null } },
json:
{ value: 'fs.createReadStream("/Users/df/Desktop/a.json")',
options: { filename: '/Users/df/Desktop/a.json', contentType: null } } } };
request(options, function (error, response, body) {
if (error) throw new Error(error);
console.log(body);
});
