Php AFNetworking正在接收尚未由服务器发送的状态代码

我有一个基本的php脚本代码，它接收JSON POST并发回http状态代码

PHP成功接收JSON并发送http 200状态代码，但在（200-299）中获得

预期状态代码，获得500

，在PHP脚本中我定义了500个状态代码，但我从未使用/发送该状态代码，我一直在一遍又一遍地寻找php脚本，没有它发送正确的代码

200

，但是AFNetworking接收到它的代码是

500

PHP:

IOS

错误：

Error: Error Domain=AFNetworkingErrorDomain Code=-1011 "Expected status code in (200-299), got 500" UserInfo=0x11c8c9d0 {NSLocalizedRecoverySuggestion="Event Deleted", AFNetworkingOperationFailingURLRequestErrorKey=<NSMutableURLRequest http://host.php>, NSErrorFailingURLKey=http://host.php, NSLocalizedDescription=Expected status code in (200-299), got 500, AFNetworkingOperationFailingURLResponseErrorKey=<NSHTTPURLResponse: 0xa9aba80>

Error:Error Domain=AFNetworkingErrorDomain code=-1011“预期状态代码在（200-299）中，获得500”UserInfo=0x11c8c9d0{nsLocalizedRecoverysSuggestion=“事件已删除”，AFNetworkingOperationFailingURLRequestErrorKey=，NSErrorFailingURLKey==http://host.php，NSLocalizedDescription=中的预期状态代码（200-299），获得500，AFNetworkingOperationFailingURLResponseErrorKey=

正如您在错误中看到的，它说的是

nsLocalizedRecoverysSuggestion=“Event Deleted”

，因此php确实发送了

200

我做错了什么？

500是内部服务器错误的HTTP状态代码。问题完全在于您的php脚本如何响应请求。

php/服务器日志中是否有关于响应的任何内容？另外，您是否能够在浏览器中测试请求？我在中找不到

sendResponse

。我有用curl测试它，它返回“Event Deleted”

curl-v-H“Accept:application/json”-H“Content type:application/json”-X POST-d'{“Event_id”：[“420”]}'  http://host.php

-v

还应显示响应标题。我假设您将返回

作为第一个响应行。您可以共享完整的curl输出吗？然后尝试更正我的php脚本，并在有响应行时发布我的解决方案
