通过 REST 控制器上传文本文件

Question

我尝试将 form/multipart-data 发送到我的其余控制器端点，但它总是抛出错误。

我认为最重要的是错误行：

Required argument [CompletedFileUpload uploadFiles] not specified

我在控制台中看到文件中的文本已传递，但方法参数不满足。

邮递员的测试请求：

curl -X POST \
  http://localhost:8080/v1/staff/code \
  -H 'Accept: */*' \
  -H 'Accept-Encoding: gzip, deflate' \
  -H 'Authorization: Bearer eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiJXQUs4ODY2NDQyMjAwIiwibmFtZSI6IkpvaG4gRG9lIiwiaWF0IjoxNTE2MjM5MDIyLCJleHAiOjI1MTYyMzkwMjJ9.7l_WP6tYT3hv-oQc4iIboFUqStjbP04WiyHPYJ-EqYc' \

  -H 'content-type: multipart/form-data; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW' \
  -F emails=@/C:/Users/ondra/Desktop/emails.txt

我的休息控制器

 @Post(consumes = MediaType.MULTIPART_FORM_DATA)
 public HttpResponse sendCodesToEmails(CompletedFileUpload uploadFile) {}

Answer 1

参数名称必须与部分名称匹配，否则使用@Part注释。

CompletedFileUpload uploadFile -> CompletedFileUpload emails

或

@Part("emails") CompletedFileUpload uploadFile
