【问题描述】：

我向这样的 url 发送 GET 请求：https://test.com/app/login?json="user":"[e-mail]","password":"test"

但返回此错误：

Error Domain=AFNetworkingErrorDomain Code=-1016 "Request failed: unacceptable content-type: text/plain" UserInfo=0x9ad3520 NSErrorFailingURLKey=https://test.com/app/login?json=%7B%22user%22:[e-mail]%22,%22password%22:%22test%22%7D, AFNetworkingOperationFailingURLResponseErrorKey=  URL: https://test.com/app/login?json=%7B%22user%22:[e-mail]%22,%22password%22:%22test%22%7D   status code: 200,

    "Set-Cookie" = "APP-SESSION-ID=xxxxxxxxxxxxxxxx; Path=/app/; HttpOnly, APP-ROUTE-ID=.app1_node2; path=/, API-ROUTE-ID=.app1_node2; path=/";
     

, NSLocalizedDescription=Request failed: unacceptable content-type: text/plain

这是我的代码，我使用 NSUTF8StringEncoding 添加了百分比转义。

manager = [AFHTTPRequestOperationManager manager];
manager.responseSerializer = [AFHTTPResponseSerializer serializer];
[manager GET:url parameters:nil success:^(AFHTTPRequestOperation *operation, id   responseObject) 

 failure:^(AFHTTPRequestOperation *operation, NSError *error) 

];

【问题讨论】：

将此作为答案并自己接受

@Lithu T.V 感谢您的提醒。

【参考方案1】：

我已经解决了这个问题。

manager.responseSerializer.acceptableContentTypes = [NSSet setWithObject:@"text/plain"]; 

参考：github.com/AFNetworking/AFNetworking/issues/1586

我使用了您的代码，并得到其他错误代码=3840。我检查的主机也有 api 响应 json 类型和文本类型。这会导致错误吗？谢谢
