Question

我在使用RestKit时遇到了最奇怪的错误。这是错误的本地化描述 -

Expected content type {(
    "application/json",
    "text/html",
    "text/plain",
    "application/x-www-form-urlencoded"
)}, got {application/json}

如您所见，我期待“application / json”作为内容类型，并且服务器正在返回application / json。我不知道为什么我会收到这个错误！

更新 -

经过一些调试后，我发现问题在于我在响应中得到的“Content-Type”的值。正如您在上面的示例中所看到的，值为“{application/json, q=1000}”而不是“application/json”。出于某种原因，RestKit将其读作“{application/json”（省略逗号之后的内容，并注意起始括号），因此找不到与预期类型匹配的内容。

为了以肮脏的方式“解决”它，我添加了以下行（注意“application / json”之前的“{”）

[RKMIMETypeSerialization registerClass:[RKNSJSONSerialization class] forMIMEType:@"{application/json"];

但我们都知道它不是正确的方法。我不知道这里有什么问题，服务器发送的内容是不正确的？或者RestKit应该以不同的方式阅读它？

Answer 1

我无法找到服务器返回＆＃34;错误＆＃34;内容类型。服务器的开发人员否认它做错了什么。所以我最终使用了我的脏黑客并添加了一个＆＃34; {＆＃34;之前＆＃34; application / json＆＃34;。

[RKMIMETypeSerialization registerClass:[RKNSJSONSerialization class] forMIMEType:@"{application/json"];

RestKit - 预期的内容类型application / json
