iOS 应用程序调用重定向域

Question

我正在创建基于休息的应用程序，当我向服务器网址发出请求时:示例:107.XXX.XXX.XXX:8080/taxi - 它正在工作，返回 JSON。但是当我向转发到该 IP 的域发出请求时，我的应用程序向我显示了该异常:

2017-04-18 20:23:53.063 Project X[4121:301275] http://107.XXX.XXX.XXX:8080/taxi  2017-04-18 20:23:53.065 Project X[4121:301275] fireGetWebserviceCall finally  2017-04-18 20:23:53.252 Project X[4121:301275] Error: Error Domain=com.alamofire.error.serialization.response Code=-1011 "Request failed: not found (404)" UserInfo={NSUnderlyingError=0x600000240600 {Error Domain=com.alamofire.error.serialization.response Code=-1016 "Request failed: unacceptable content-type: text/html" UserInfo={com.alamofire.serialization.response.error.response= { URL: http://107.XXX.XXX.XXX:8080/taxi } { status code: 404, headers {    "Content-Language" = en;    "Content-Length" = 977;    "Content-Type" = "text/html;charset=utf-8";    Date = "Tue, 18 Apr 2017 17:23:51 GMT";    Server = "Apache-Coyote/1.1";} }

当我将该 URL 粘贴到浏览器中时，我得到正常的 JSON 响应。有人可以向我解释为什么返回的信息是 text/html 以及如何修复它吗？

Answer 1

我使用下面的代码来确保从 URL 返回 JSON 响应:

swift

        var request = URLRequest(url: self.url!)
        request.httpMethod = self.httpMethod
        request.httpBody = body
        request.addValue("application/json", forHTTPHeaderField: "Content-Type")
        request.addValue("application/json", forHTTPHeaderField: "Accept")
