php - AFNetworking 发布错误

Question

我正在尝试发送一个 POST 请求，其中有 2 个参数，然后会返回一个 json 对象。我正在使用 AFNetworking，每次都会收到此错误:

Error: Error Domain=com.alamofire.error.serialization.response Code=-1011 "Request failed: not found (404)" UserInfo=0x16d93980 {com.alamofire.serialization.response.error.response=  <NSHTTPURLResponse: 0x16d8f0d0> { URL: http://LINK } { status code: 404, headers {
    Connection = "Keep-Alive";
    "Content-Length" = 285;
    "Content-Type" = "text/html; charset=iso-8859-1";
    Date = "Fri, 11 Jul 2014 16:43:42 GMT";
    "Keep-Alive" = "timeout=5, max=99";
    Server = "Apache/2.4.9 (Ubuntu)";
} }, NSErrorFailingURLKey=http://LINK, NSLocalizedDescription=Request failed: not found (404),     NSUnderlyingError=0x16d8f880 "Request failed: unacceptable content-type: text/html"}

POST Objective-c 请求

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
[manager POST:@"LINK"

   parameters:@{@"number": storeID, @"udid" : [UIDevice currentDevice].identifierForVendor.UUIDString}
      success:^(AFHTTPRequestOperation *operation, id responseObject) {
          NSLog(@"JSON: %@", responseObject);
      } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
          NSLog(@"Error: %@", error);
      }];


NSLog(@"%@ = %@", storeID, [UIDevice currentDevice].identifierForVendor.UUIDString);

用于测试的php脚本

    $var = $_POST["number"];
    $udid = $_POST["udid"];

     echo '{"match": 1}';

您的 AFHTTPRequestOperationManager 序列化程序需要 json 内容类型。但你的 PHP 同行将其响应为 html。

在 PHP 中尝试一下:

$var = $_POST["number"];
$udid = $_POST["udid"];

header('Content-Type: application/json');
echo '{"match": 1}';

或者，您可以为您的管理器设置其他序列化程序并手动解析响应:

manager.responseSerializer = [AFHTTPResponseSerializer serializer];
