ios - 获取操作时的 REstkit 错误

Question

我正在执行 Restkit GET 操作，但 Restkit 出现错误。我在 Chrome 上使用 REST 控制台尝试了相同的操作，它有效:

GET 操作的细节是:网址:https://www.ez-point.com/ezpoints操作:GET授权 header :xxxxxxxxxxxxxxxxxxxxxx

借助 Chrome REST 控制台，它可以正常工作，我得到了 JSON 格式的正确响应。

对于 Restkit，它不起作用。这些是我的 Restkit 代码:

//trying restkit
    NSURL *endpoint = [NSURL URLWithString:@"https://www.ez-point.com/"];
    RKObjectManager* objectManager = [RKObjectManager managerWithBaseURL:endpoint];
    [objectManager.HTTPClient setAuthorizationHeaderWithToken:@"xxxxxxxxxxxxxxxxxxx"];
    [objectManager getObjectsAtPath:@"ezpoints" parameters:nil success:^(RKObjectRequestOperation *operation, RKMappingResult *mappingResult) {
        NSLog(@"Success");
       //NSLog(mappingResult);
    } failure:^(RKObjectRequestOperation *operation, NSError *error) {
        NSLog(@"Failure");
        //NSLog(operation);
        //NSLog(error);
    }];

我收到这个错误:

有什么建议吗？

错误已经给出了提示:它默认不接受“text/xml”作为内容类型。现在，它接受

• 应用程序/x-www-form-urlencoded
• 应用程序/json

您可以使用 RKMIMETypeSerialization 注册它，并将“text/xml”添加到接受的内容类型之一:

[RKMIMETypeSerialization registerClass:[RKXMLReaderSerialization class] forMIMEType:RKMIMETypeTextXML];
[objectManager setAcceptHeaderWithMIMEType:@"text/xml"];
