本文介绍了删除Transfer-Encoding:在POST请求中分块?的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我使用以下代码发送 POST
请求,但请求以chunked的形式发送( Transfer-Encoding:chunked
)。我用Google搜索了问题并说它包含了 Content-Length
但是在下面的代码中我无法弄清楚如何设置 Content-长度
:
I am sending a POST
request using the following code but the request is send in the form of chunked (Transfer-Encoding: chunked
). I googled about the problem and it says to include the Content-Length
but in the below code I could not figure out how could I set the Content-Length
:
@RequestMapping(value = "/contacts", method = RequestMethod.POST)
public Map<String, ContactInfo> addContactInfo(
@RequestBody Map<String, ContactInfo> ContactInfoDto) {
ContactInfo contactInfo = ContactInfoDto.get("contact");
if (contactInfo == null) {
throw new IllegalArgumentException("Contact not found.");
}
contactInfo = this.contactInfoManager.addNew(contactInfo);
Map<String, ContactInfo> map = new HashMap<>();
map.put("contact", contactInfo);
return map;
}
推荐答案
你可以使用 ResponseEntity
显式设置标头。棘手的一点是弄清楚你的内容实际有多长:
You can use ResponseEntity
to set headers explicitly. The tricky bit is figuring out how long your content actually is:
@RequestMapping(value = "/contacts", method = RequestMethod.POST)
public ResponseEntity<Map<String, ContactInfo>> addContactInfo(@RequestBody Map<String, ContactInfo> contactInfoDto) throws JsonProcessingException {
ContactInfo contactInfo = contactInfoDto.get("contact");
if (contactInfo == null) {
throw new IllegalArgumentException("Contact not found.");
}
contactInfo = this.contactInfoManager.addNew(contactInfo);
Map<String, ContactInfo> map = new HashMap<>();
map.put("contact", contactInfo);
HttpHeaders headers = new HttpHeaders();
headers.set(HttpHeaders.CONTENT_LENGTH, String.valueOf(new ObjectMapper().writeValueAsString(map).length()));
return new ResponseEntity<Map<String, ContactInfo>>(map, headers, HttpStatus.CREATED);
}
测试:
$ curl -v http://localhost:8080/contacts/ -X POST -d '{ "contact": { "name": "foo" } }' -H 'Content-Type: application/json' && echo
