如何使用 org.jboss.resteasy.client.ClientRequest

Question

我需要维护一个旧版软件。我们如何上传文件？org.jboss.resteasy.client.ClientRequestorg.springframework.web.multipart.MultipartFile

简而言之，我想实现：使用.可以是任何文件作为字符串路径示例：.curl -X POST http://mydomain/upload?sender=mr_abc -F file=@${FILE}ClientRequest${FILE}/Users/mr_abc/mytarfile.tar

这是我拥有的：

request = new ClientRequest("http://mydomain/upload");

request.header("Content-Type","multipart/form-data");

request.queryParameter("sender", "mr_abc");

request.queryParameter("file", new File("/Users/mr_abc/mytarfile.tar"));

ClientResponse<String> response = request.post(String.class);

这导致错误Required request part 'file' is not present

我们需要添加：<dependency>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <groupId>org.jboss.resteasy</groupId>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <artifactId>resteasy-multipart-provider</artifactId>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <version>3.0.19.Final</version>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <scope>test</scope></dependency>我之前尝试过版本2.3.5.Final，但失败了，所以3.0.19似乎是一个更好的版本。而在java代码中将需要使用类MultiPartFormDataOutputFile file = new File("/Users/mr_abc/mytarfile.tar");MultipartFormDataOutput upload = new MultipartFormDataOutput();&nbsp; &nbsp; &nbsp; &nbsp; upload.addFormData("file", targetStream, MediaType.MULTIPART_FORM_DATA_TYPE, "mytarfile.tar");request = new ClientRequest("http://mydomain/upload");request.queryParameter("sender", "mr_abc");request.body(MediaType.MULTIPART_FORM_DATA_TYPE, upload);ClientResponse<String> response = request.post(String.class);
