将 .jpeg 和 .png 上传到 Java GraphQL 服务器时不支持内容类型 multipart

Question

我正在关注这个answer 来实现graphql 文件上传。

compile group: 'commons-fileupload', name: 'commons-fileupload', version: '1.4'

Application.yml

spring.servlet.multipart.enabled=true

Spring Boot 应用类

@EnableAutoConfiguration(exclude={MultipartAutoConfiguration.class})

然后在你的@Configuration 中添加一个@Bean

@Bean(name = "multipartResolver")
public CommonsMultipartResolver multipartResolver() {
    CommonsMultipartResolver multipartResolver = new CommonsMultipartResolver();
    multipartResolver.setMaxUploadSize(100000);
    return multipartResolver;
}

但我不断得到

Content type 'multipart/form-data;boundary=----WebKitFormBoundarygiGMuLecC2onH3UB' not supported

痕迹是

我正在做的前端

import {useDropzone} from 'react-dropzone'

const DragDrop = ({mutate}: { mutate: any }) => {
  const onDrop = useCallback((acceptedFiles: any) => {
    console.log(acceptedFiles)
    // Do something with the files
    mutate({variables: {file: acceptedFiles[0]}})
  }, []);
  const {getRootProps, getInputProps, isDragActive} = useDropzone({onDrop});
  return (

    <div {...getRootProps()}>
      <input {...getInputProps()} />
      {
        isDragActive ?
          <p>Drop the files here ...</p> :
          <p>Drag 'n' drop some files here, or click to select files</p>
      }
    </div>
  )
};

const UploadFiles = () => {
    return (
      <Mutation mutation={gql` mutation($file: Upload!) { uploadFile(file: $file) } `}>
        {(mutate: any) => { return (<DragDrop mutate={mutate}/>); }}
      </Mutation>
    );
};

Answer 1

由于声誉低，无法发表评论。根据日志，看起来甚至多部分数据也被视为内容类型。实际值应该只是“多部分/表单数据”，但在这种情况下，即使上传的文件内容似乎也是内容类型的一部分标题
