我正在尝试使用 Mule ESB 发布多部分/表单数据，但无法使其正常工作。我通过我的休息客户端和 cURL 成功完成了相同的请求。

curl -i -X POST \
-H "Authorization:bearer xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx" \
-H "X-ANYPNT-ORG-ID:xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx" \
-H "X-ANYPNT-ENV-ID:xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx" \
-H "Content-Type:multipart/form-data" \
-F "artifactName=test" \
-F "targetId=xxxxxx" \
-F "file=@\"./test-1.0.0-SNAPSHOT.zip\";type=application/x-zip-compressed;filename=\"test-1.0.0-SNAPSHOT.zip\"" \ 'https://anypoint.mulesoft.com/hybrid/api/v1/applications'

我正在使用 Transformer 添加出站附件；

message.setPayload(NullPayload.getInstance());
message.addOutboundAttachment("artifactName", AttachmentHelper.getStringAttachment("artifactName", artifactName));
message.addOutboundAttachment("targetId", AttachmentHelper.getStringAttachment("targetId", targetId.toString()));
message.addOutboundAttachment("file", AttachmentHelper.getURLAttachment("file", file));

public class AttachmentHelper {
  public static DataHandler getStringAttachment(String name, String value) {
    logger.info("Adding string attachment " + name + ": " + value);
    byte[] bytes = value.getBytes();
    return new DataHandler(new ByteArrayDataSource(bytes, "text/plain", name));
  }

  public static DataHandler getURLAttachment(String name, String value) throws Exception {
    InputStream is = new URL(value).openStream();
    byte[] bytes = IOUtils.toByteArray(is);
    return new DataHandler(new ByteArrayDataSource(bytes, "application/x-zip-compressed", name));
  }
}

然后只需拨打服务电话；

<http:request method="POST" path="/hybrid/api/v1/applications" config-ref="http_request_mule" doc:name="POST Deploy Application Call">
        <http:request-builder>
            <http:header headerName="Authorization" value="bearer #[sessionVars.token]" />
            <http:header headerName="X-ANYPNT-ORG-ID" value="#[sessionVars.orgId]" />
            <http:header headerName="X-ANYPNT-ENV-ID" value="#[sessionVars.envId]" />
            <http:header headerName="Content-Type" value="multipart/form-data" />
        </http:request-builder>
    </http:request>

我得到了一个 HTTP 状态 400，当我注释掉 HTTP 调用时，我可以看到请求的格式不正确；

Unexpected character (-) at position 0.
--null
Content-Type: application/x-zip-compressed

C:\DEV\zips\test-1.0.0-SNAPSHOT.zip (byte content removed for post)
--null
Content-Type: text/plain

xxxxxx (value correct here just masked)
--null
Content-Type: text/plain

test
--null--

似乎无法添加内容配置、附件名称和文件名。

我几乎尝试了所有内容，阅读了几乎所有内容，但不知所措。有任何想法吗？

解决了！我必须做的唯一改变是添加文件名；

message.addOutboundAttachment("file", AttachmentHelper.getURLAttachment(FilenameUtils.getName(file), file));
