AFHTTPRequestOperationManager 获取请求失败，错误域=AFNetworkingErrorDomain Code=-1016

Question

我向这样的 url 发送 GET 请求：https://test.com/app/login?json={"user":"test@gmail.com","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:%22test@gmail.com%22,%22password%22:%22test%22%7D, AFNetworkingOperationFailingURLResponseErrorKey= { URL: https://test.com/app/login?json=%7B%22user%22:%22test@gmail.com%22,%22password%22:%22test%22%7D } { status code: 200, 

    headers {
    "Cache-Control" = "max-age=900";
    Connection = "Keep-Alive";
    "Content-Length" = 6116;
    "Content-Type" = "text/plain; charset=UTF-8";
    Date = "Wed, 15 Jan 2014 09:14:22 GMT";
    Expires = "Wed, 15 Jan 2014 09:29:22 GMT";
    "Keep-Alive" = "timeout=2, max=100";
    Server = "Apache-Coyote/1.1";
    "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) {

}];

我已经解决了这个问题。

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