删除POST请求中的Transfer-Encoding：chunked？

我正在POST使用以下代码发送请求，但请求以组块（Transfer-Encoding:

chunked）的形式发送。我用谷歌搜索了这个问题，它说要包含，Content-Length但是在下面的代码中我不知道如何设置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;
}

回答：

您可以用来ResponseEntity显式设置标题。棘手的一点是弄清楚您的内容实际上有多长时间：

@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
