英文:
Getting 415 error from POST to download file
问题
以下是您提供的内容的翻译：
我正在使用Spring Rest来下载一个zip文件，其内容由一系列文档ID确定。
我的控制器如下所示：
@RestController
@RequestMapping("api/zip-documents")
public class DocumentsRestController {
@Autowired
private DocumentDownloadService documentDownloadService;
@PostMapping(produces = {"application/zip"}, consumes = {"application/json"})
public ResponseEntity<Resource> downloadZip(@RequestBody List<String> documentIds) throws IOException {
// 将文档压缩到文件中
ByteArrayOutputStream outputStream = documentDownloadService.downloadZip(documentIds);
ByteArrayResource resource = new ByteArrayResource(outputStream.toByteArray());
return ResponseEntity.ok().header("Content-Disposition", "attachment; filename=\"file.zip\"")
.contentLength(outputStream.size()).body(resource);
}
}
我的测试使用Mockito如下，运行应用程序时也遇到相同的问题：
@Test
public void downloadZip_sunnyDayUseCase_contentTypeIsZip() throws Exception {
Mockito.when(documentDownloadService.downloadZip(Matchers.anyListOf(String.class)))
.thenReturn(new ByteArrayOutputStream());
mockMvc
.perform(post("/api/zip-documents")
.content("{ \"documentIds\": [\"123123\"] }"))
.andExpect(status().isOk())
.andExpect(content().contentType("application/zip"));
}
我得到了一个HttpStatus 415的响应。这似乎是请求头的问题，因为我无法在restcontroler中设置断点。
英文:
I am using Spring Rest to download a zip file, then contents of which are determined by a list of document ids.
My Controller is like so
@RestController
@RequestMapping("api/zip-documents")
public class DocumentsRestController {
@Autowired
private DocumentDownloadService documentDownloadService;
@PostMapping(produces = {"application/zip"}, consumes = {"application/json"})
public ResponseEntity<Resource> downloadZip(@RequestBody List<String> documentIds) throws IOException {
// Zip the documents into a file
ByteArrayOutputStream outputStream = documentDownloadService.downloadZip(documentIds);
ByteArrayResource resource = new ByteArrayResource(outputStream.toByteArray());
return ResponseEntity.ok().header("Content-Disposition", "attachment; filename=\"file.zip\"")
.contentLength(outputStream.size()).body(resource);
}
}
My test, using Mockito is as follows, and I also get the same issue when running the app:
@Test
public void downloadZip_sunnyDayUseCase_contentTypeIsZip() throws Exception {
Mockito.when(documentDownloadService.downloadZip(Matchers.anyListOf(String.class)))
.thenReturn(new ByteArrayOutputStream());
mockMvc
.perform(post("/api/zip-documents")
.content("{ \"documentIds\": [\"123123\"] }"))
.andExpect(status().isOk())
.andExpect(content().contentType("application/zip"));
}
I'm getting a HttpStatus 415 response. This seems to be an issue with the request header, as I cannot hit a breakpoint in the restcontroler.

HTTP状态码415代表不支持的媒体类型。由于您正试图向端点发布JSON数据，您可能希望在POST请求中的某个位置添加Content-Type: application/json头部。
因此，在您的mockMvc中，我猜您可以尝试以下操作：
mockMvc
.perform(post("/api/zip-documents")
.header("Content-Type", "application/json")
.content("{ \"documentIds\": [\"123123\"] }"))
.andExpect(status().isOk())
.andExpect(content().contentType("application/zip"));
英文:
HTTP Status Code 415 stands for Unsupported Media Type. Since you are trying to post JSON data to the endpoint, you probably want a Content-Type: application/json header somewhere in your POST.
So, in your mockMvc, I guess try the following:
mockMvc
.perform(post("/api/zip-documents")
.header("Content-Type", "application/json")
.content("{ \"documentIds\": [\"123123\"] }"))
.andExpect(status().isOk())
.andExpect(content().contentType("application/zip"));
