服务器端正在接收错误的内容类型(发送的旧报头)

Question

由于64位，我将afnetwork更新为2.0。我犯了一个错误，首先使用AFHTTPRequestSerializer，但服务器端只接受Json。令人担忧的是，即使我使用AFHTTPRequestSerializer，它对我来说也很好，所以我没有注意到这个问题，并将错误应用程序发布到公众。然后我不断收到用户抱怨，不知怎么的，我在我的设备上重建我的应用程序，本地服务器可以捕获我的错误内容类型(应用程序/x-www.form-urlencoded)。在我将AFHTTPRequestSerializer更新为AFJSONRequestSerializer之后，它并没有解决问题，但用户仍然不断向服务器发送错误的内容类型，即使他们更新了应用程序。新用户没有问题，只发生在老用户身上。

是否与缓存问题有关?

服务器日志:

我的代码是

 AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.requestSerializer = [AFJSONRequestSerializer serializer];
manager.responseSerializer = [AFJSONResponseSerializer serializer];
AFHTTPRequestOperation *operation = [manager POST:_url parameters:requestParams success:^(AFHTTPRequestOperation *operation, id responseObject) {
    NSLog(@"operation success: %@n %@", operation, responseObject);
    NSDictionary *decoded = [self processResponce:responseObject failureBlock:failureBlock];
                            if (!decoded) return;
                            BOOL containsError = [self checkErrorStatus:decoded failureBlock:failureBlock];
                            if (containsError) return;
                            successBlock(decoded[@"Data"]);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
        failureBlock(FailureTypeUnknown, [error localizedDescription]);
}];
[operation setUploadProgressBlock:^(NSUInteger bytesWritten, long long totalBytesWritten, long long totalBytesExpectedToWrite) {
progressBlock(bytesWritten,totalBytesWritten,totalBytesExpectedToWrite);
}];

根据您的回复，请设置您的经理的内容类型如下

manager.responseSerializer.acceptableContentTypes = [NSSet setWithObject:@"application/json"];
