服务器端接收到错误的内容类型（发送的旧标头）

Question

由于 64 位，我将 afnetwork 更新为 2.0。我一开始使用AFHTTPRequestSerializer时犯了一个错误，但是服务器端只接受Json。令人担忧的是，即使我使用了 AFHTTPRequestSerializer，它对我来说也能正常工作，所以我没有注意到这个问题并将错误应用程序发布给公众。然后我不断收到用户抱怨，不知何故我在我的设备上重建了我的应用程序，本地服务器可以捕获我错误的内容类型（应用程序/x-www.form-urlencoded）。在我将 AFHTTPRequestSerializer 更新为 AFJSONRequestSerializer 后，它并没有解决问题，但是即使他们更新了应用程序，用户仍然会不断向服务器发送错误的内容类型。新用户没有问题，只发生在老用户身上。

这与缓存问题有关吗？

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，请将您经理的内容类型设置如下

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