在swift3中通过Alamofire发出请求时出现404错误

首先,我们使用下面的代码,因为api只适用于移动设备,而不适用于浏览器。 "

$iPod = stripos($_SERVER['HTTP_USER_AGENT'], "iPod");
    $iPhone = stripos($_SERVER['HTTP_USER_AGENT'], "iPhone");
    $iPad = stripos($_SERVER['HTTP_USER_AGENT'], "iPad");
    $Android = stripos($_SERVER['HTTP_USER_AGENT'], "Android");

$json_data = json_decode(file_get_contents('php://input'));
if ($json_data) {
    $username_1 = $json_data->username;
    if ($Android || $iPad || $iPhone || $iPod) {}

其次,api正在使用AFNetworking在android(使用volley)和ios objective-c上工作。但是,现在我将项目移植到swift3,我正在使用" Alamofire"用于网络电话。

方法::(这是我发出POST请求的方式):

let headers : HTTPHeaders = [
            "Accept" : "application/json"
        ]

Alamofire.request("API URL", method: .post, parameters: parameters, encoding: JSONEncoding.default, headers: headers)
            .responseJSON{
                response in
                if let json = response.result.value{
                }

但是,我收到错误404,我们通常在浏览器中遇到api时会得到错误。 之后,我删除了后端检查,请求工作正常,得到了正确的响应。但是,我们无法删除该支票。所以请帮助我,如果我在其他方面的标题上犯了任何错误。

这是我在debugPrint(response)::

中得到的
{ status code: 200, headers {
    "Access-Control-Allow-Origin" = "*";
    "Cache-Control" = "no-store, no-cache, must-revalidate, post-check=0, pre-check=0";
    Connection = "Keep-Alive";
    "Content-Encoding" = gzip;
    "Content-Length" = 84;
    "Content-Type" = "text/html; charset=UTF-8";
    Date = "Thu, 14 Sep 2017 17:03:17 GMT";
    Expires = "Thu, 19 Nov 1981 08:52:00 GMT";
    "Keep-Alive" = "timeout=5";
    Pragma = "no-cache";
    Server = "Apache/2.4.25";
    Vary = "Accept-Encoding,User-Agent";
    "X-Powered-By" = "PHP/5.6.31";
} }
[Data]: 80 bytes
[Result]: SUCCESS: {
    "is_valid" = 0;
    status = 404;
    "status_message" = "access denied";
    success = 0;
}

1 个答案:

答案 0 :(得分:0)

Alomafire发送默认的标头参数User-Agent,但其值类似于此iOS Example/1.0 (com.alamofire.iOS-Example; build:1; iOS 10.0.0) Alamofire/4.0.0

这是他们的自述文件: enter image description here

您显然可以提供自己的自定义标题:

let headers: HTTPHeaders = [
  "User-Agent": "iPhone",
  "Accept": "application/json"
]

Alamofire.request("<Ypur URL>", headers: headers)
  .responseJSON { response in
  debugPrint(response)
}

或者,如果您想保留其他默认标头参数

var headers = Alamofire.SessionManager.defaultHTTPHeaders
headers["User-Agent"] = "iPhone"
