用Quarkus处理多部分/表单数据

Question

我遇到了一个问题，我无法在我的资源中获取我的表单，变量总是为空

我的资源：

    @POST
    @Path("/upload-logo")
    @Consumes(MediaType.MULTIPART_FORM_DATA)
    @Produces(MediaType.TEXT_PLAIN)
    public String uploadLogo (@MultipartForm LogoMultipartForm logoMultipartForm) throws IOException {
        return this.companyService.uploadLogo(username, logoMultipartForm.logo);

    }

表单模型

public class LogoMultipartForm {

    @FormParam("logo")
    public byte[] logo;

    @FormParam("filename")
    @PartType("text/plain")
    public String fileName;
}

我的取货请求：

  uploadLogo: async (file: File) => {
    const form = new FormData();
    form.append("logo", file, "logo.png");
    form.append("filename", "test");

    const { query, abort } = HttpClient.POST(`${COMPANY_URL}/upload-logo`, form);
    let promise = query
      .then((res: any) => {
        console.log("Response", res);
        if (res.status === 200) {
          return res.text();
        } else {
          throw res;
        }
      })
      .then((url: any) => url);

    promise.cancel = abort;

    return promise;
  },

和我的HttpClient：

  POST: function (url: string, body: any, config?: any) {
    const controller = new AbortController();
    const signal = controller.signal;
    return { query: fetch(url, { signal, method: "POST", body, ...config }) as any, abort: () => controller.abort() };
  },

为了确保我正在使用代理进行测试并且请求实际上是好的：变量文件名和徽标始终为空。

这是我的绒球.xml：

    <dependency>
      <groupId>io.quarkus</groupId>
      <artifactId>quarkus-resteasy</artifactId>
    </dependency>

      <artifactId>quarkus-resteasy-multipart</artifactId>

  </dependencies>

我不知道问题出在哪里。

我已经看过了多部分的官方resteasy文档，看不出问题在哪里。我已经用MultipartFormDataInput测试过，所有部分都是空的。

提前感谢您的帮助！:)

您缺少依赖项：

<dependency>
    <groupId>org.jboss.resteasy</groupId>
    <artifactId>resteasy-multipart-provider</artifactId>
</dependency>

确保您的< code > @ part type(" text/plain ")继承自org.jboss.resteasy包！以及< code > @ multipart form (import org . JBoss . rest easy . annotations . providers . multipart . multipart form；)

有一个很好的例子是如何工作的：Quarkus教程。看看包装！
