Status Code¶
Table 1 describes the status codes.
Status Code | Code | Status Code Description |
|---|---|---|
100 | Continue | The client continues sending the request. This provisional response informs the client that part of the request has been received and has not yet been rejected by the server. |
101 | Switching Protocols | Switching protocols. The target protocol must be more advanced than the source protocol. For example, the current HTTP protocol is switched to a later version of HTTP. |
200 | OK | The request has been fulfilled. |
201 | Created | The request for creating a resource has been fulfilled. |
202 | Accepted | The request has been accepted, but the processing has not been completed. |
203 | Non-Authoritative Information | Non-authoritative information. The request is successful. |
204 | NoContent | The request has been fulfilled, but the HTTP response does not contain a response body. The status code is returned in response to an HTTP OPTIONS request. |
205 | Reset Content | The server has fulfilled the request, but the requester is required to reset the content. |
206 | Partial Content | The server has successfully processed a part of the GET request. |
300 | Multiple Choices | There are multiple options for the location of the requested resource. The response contains a list of resource characteristics and addresses from which the user or user agent (such as a browser) can choose the most appropriate one. |
301 | Moved Permanently | The requested resource has been assigned a new permanent URI, and the new URI is contained in the response. |
302 | Found | The requested resource resides temporarily under a different URI. |
303 | See Other | The response to the request can be found under a different URI, and should be retrieved using a GET or POST method. |
304 | Not Modified | The requested resource has not been modified. When the server returns this status code, it does not return any resources. |
305 | Use Proxy | The requested resource must be accessed through a proxy. |
306 | Unused | The HTTP status code is no longer used. |
400 | BadRequest | The request is invalid. Do not retry the request before modification. |
401 | Unauthorized | The status code is returned after the client provides the authentication information, indicating that the authentication information is incorrect or invalid. |
402 | Payment Required | This status code is reserved for future use. |
403 | Forbidden | The request has been rejected. The server has received and understood the request; yet it refused to respond, because the request is set to deny access. Do not retry the request before modification. |
404 | NotFound | The requested resource cannot be found. Do not retry the request before modification. |
405 | MethodNotAllowed | The request contains one or more methods not supported for the resource. Do not retry the request before modification. |
406 | Not Acceptable | The server cannot fulfill the request according to the content characteristics of the request. |
407 | Proxy Authentication Required | This status code is similar to 401, but the client must first authenticate itself with the proxy. |
408 | Request Time-out | The request timed out. The client may repeat the request without modifications at any time later. |
409 | Conflict | The request could not be processed due to a conflict with the current state of the resource. This status code indicates that the resource that the client attempts to create already exits, or the requested update failed due to a conflict. |
410 | Gone | The requested resource is no longer available. The status code indicates that the requested resource has been deleted permanently. |
411 | Length Required | The server refuses to process the request without a defined Content-Length. |
412 | Precondition Failed | The server does not meet one of the preconditions that the requester puts on the request. |
413 | Request Entity Too Large | The request is larger than that a server is able to process. The server may close the connection to prevent the client from continuing the request. If the server cannot process the request temporarily, the response will contain a Retry-After header field. |
414 | Request-URI Too Large | The URI provided was too long for the server to process. |
415 | Unsupported Media Type | The server is unable to process the media format in the request. |
416 | Requested range not satisfiable | The requested range is invalid. |
417 | Expectation Failed | The server fails to meet the requirements of the Expect request-header field. |
422 | UnprocessableEntity | The request is well-formed but is unable to be processed due to semantic errors. |
429 | TooManyRequests | The client has sent excessive number of requests to the server within a given time (exceeding the limit on the access frequency of the client), or the server has received an excessive number of requests within a given time (beyond its processing capability). In this case, the client should resend the request after the time specified in the Retry-After header of the response has elapsed. |
500 | InternalServerError | The server is able to receive but unable to understand the request. |
501 | Not Implemented | The server does not support the requested function. |
502 | Bad Gateway | The server acting as a gateway or proxy has received an invalid request from a remote server. |
503 | ServiceUnavailable | The requested service is invalid. Do not retry the request before modification. |
