[英]Spring RestTemplate: getting 403 forbidden for multipart/form-data but working with curl
我正在使用 spring rest-template 来发布 1 个文件和 1 个字符串参数的请求form-data
,这里是代码:
HttpHeaders headers = new HttpHeaders();
headers.set("Authorization", "Bearer ...");
httpHeaders.setContentType(MediaType.MULTIPART_FORM_DATA);
File file=new File("src\main\resources\test.json");
BufferedInputStream in = new BufferedInputStream(new FileInputStream(file));
byte[] fileBytes = toByteArray(in);
MultiValueMap<String, String> fileMap = new LinkedMultiValueMap<>();
ContentDisposition contentDisposition = ContentDisposition
.builder("form-data")
.name("file")
.filename("test.json")
.build();
fileMap.add(HttpHeaders.CONTENT_DISPOSITION, contentDisposition.toString());
fileMap.add(HttpHeaders.CONTENT_TYPE, MediaType.APPLICATION_JSON_VALUE);
org.springframework.http.HttpEntity<byte[]> fileEntity =
new org.springframework.http.HttpEntity<>(fileBytes, fileMap);
MultiValueMap< String, Object > body = new LinkedMultiValueMap<>();
body.add("stringFormInput", "xyz");
body.add("file", fileEntity);
org.springframework.http.HttpEntity< MultiValueMap< String, Object > > entity =
new org.springframework.http.HttpEntity<>(body, httpHeaders);
ResponseEntity< JsonNode > responseEntity =
restTemplate.postForEntity("https://uploadFile", entity, JsonNode.class);
但我收到403 FORBIDDEN
响应
但是,如果我使用下面的 curl 命令,它会成功执行
curl --location --request POST 'https://uploadFile' \
--header 'Content-Type: multipart/form-data' \
--header 'Authorization: Bearer ...' \
--form 'file=@/D:/resources/test.json' \
--form 'stringFormInput=xyz' \
我也试过httpClient
,仍然是 403 没有任何原因消息
HttpPost post = new HttpPost("https://uploadFile");
post.setHeader(HttpHeaders.CONTENT_TYPE, MediaType.MULTIPART_FORM_DATA_VALUE);
post.setHeader(HttpHeaders.AUTHORIZATION, "Bearer ...");
File file=new File("src\main\resources\test.json");
MultipartEntityBuilder builder = MultipartEntityBuilder.create();
builder.setMode(HttpMultipartMode.BROWSER_COMPATIBLE);
builder.addBinaryBody("file", file, ContentType.DEFAULT_BINARY, "test.json");
builder.addTextBody("stringFormInput", "xyz", ContentType.DEFAULT_BINARY);
HttpEntity entity = builder.build();
post.setEntity(entity);
HttpClient httpClient = HttpClientBuilder.create().build();
HttpResponse response = httpClient.execute(post);
编辑
现在我通过从 JAVA 执行 curl 做了一个解决方法
File file=new File("src\main\resources\test.json");
String[] command = {"curl", "--location",
"--request", "POST", "https://uploadFile",
"--header", "Content-Type: multipart/form-data",
"--header", "Authorization: Bearer ...",
"-F", "file=" + "@"+file.getPath(),
"--form", "stringFormInput=xyz"};
ProcessBuilder builder = new ProcessBuilder(command);
builder.redirectErrorStream(true);
String curlResult = "";
String line = "";
try {
Process process = builder.start();
BufferedReader r = new BufferedReader(new InputStreamReader(process.getInputStream()));
while (true) {
line = r.readLine();
if (line == null) {
break;
}
curlResult = curlResult + line;
}
} catch (Exception e) {
e.printStackTrace();
}
所以我遇到了一个类似的问题,cURL 执行正常,但 Spring 代码给出了 403。问题在于接收此请求的目标。 很少有像 Nginx 这样的 web 服务器默认需要像“User-Agent”这样的强制标头,可以禁用。
默认情况下,Spring 不会传递任何额外的 header。 如果目标正在使用 Ngnix,请尝试添加“User-Agent”,或者找到他们正在使用的 web 服务器。
分享我的代码以供参考。
此代码给出了 403
HttpHeaders httpHeaders = new HttpHeaders(); httpHeaders.setContentType(MediaType.MULTIPART_FORM_DATA);
这段代码运行良好。
HttpHeaders httpHeaders = new HttpHeaders(); httpHeaders.setContentType(MediaType.MULTIPART_FORM_DATA); httpHeaders.add("用户代理", "PostmanRuntime/7.26.3");
