将表单数据上传到弹簧服务器时不受支持的媒体类型

我试图通过API将文件上传到远程弹簧服务器，并且即使我已经将数据转换为表单数据，我仍然收到不受支持的媒体类型错误（415）。

这里是快递http post请求：

var FormData = require('form-data');
var fs = require('fs');
var form = new FormData();

form.append('pid', params.pid);
form.append('deliveryAttachment', fs.createReadStream(params.deliveryAttachment.path));

var url = someDomain + '/proj/new/deliveryAttachment';
requestLib({
    url: url,
    method: "POST",
    jar: getJar(),
    form: form
},function (error, response, body){     
    console.log(body)
});

这里是Java Spring控制器的参考：

    @RequestMapping(value = "proj/new/deliveryAttachment", method = RequestMethod.POST, consumes = MediaType.MULTIPART_FORM_DATA_VALUE, produces = MediaType.TEXT_PLAIN_VALUE)
public String insertDeliveryAttachment(@RequestParam("pid") long pid,
        @RequestParam("deliveryAttachment") MultipartFile file) {
    try {
        DeliveryAttachment a = new DeliveryAttachment(file.getOriginalFilename(), pid);
        ps.insertDeliveryAttachment(a, file.getBytes());
        return String.valueOf(a.id);
    } catch (IOException e) {
        return "-1";
    }
}

这是表单数据控制台日志：

415回应：

{
  "timestamp": 1494671395688,
  "status": 415,
  "error": "Unsupported Media Type",
  "exception": "org.springframework.web.HttpMediaTypeNotSupportedException",
  "message": "Content type 'application/x-www-form-urlencoded' not supported",
  "path": "/proj/new/deliveryAttachment"
}

--UPDATE--

好的，我在阅读请求的文档后发现，如果您使用form作为数据的持有者，它会将数据视为application/x-www-form-urlencoded

例如; request.post({url:'http://service.com/upload', form: {key:'value'}}, function(err,httpResponse,body){ ... });

同时multipart/form-data的正确关键是formData

例如; request.post({url:'http://service.com/upload', formData: formData}, function optionalCallback(err, httpResponse, body) { ... });

我试过了，现在它给了我一个新的错误：

TypeError: Cannot read property 'name' of null at FormData._getContentDisposition

看起来你正在发送一个带有Content-Type: 'application/x-www-form-urlencoded'的POST请求Content-Type: 'application/x-www-form-urlencoded' ，你的SpringController的insertDeliveryAttachment() multipart/form-data MIME类型。

我建议您将insertDeliveryAttachment()方法上的消耗MIME类型更改为MediaType.APPLICATION_FORM_URLENCODED_VALUE

我解决了它。 我没有使用FormData，只是在一个对象中插入值并且工作。

var data = {
    pid: params.pid,
    deliveryAttachment: fs.createReadStream(params.deliveryAttachment[0].path)
};  

var url = wfDomain + '/proj/new/deliveryAttachment';
requestLib({
    url: url,
    method: "POST",
    headers: {
        'Content-Type': 'multipart/form-data'
    },  
    jar: getJar(),
    formData: data
},function (error, response, body){ ... });
