ios - AFJSONRequestOperation 在 200 response.statusCode 上命中失败 block

Question

我的 AFJSONRequestOperation 在 200 响应上遇到故障 block 。这是因为我有额外的 JSON 吗？

 [operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {
    NSDictionary *d = (NSDictionary *)responseObject;
    bool required = [d[@"payment_required"] boolValue];
    [self.delegate paymentRequired:required];
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    int statusCode = operation.response.statusCode;
    NSLog(@"status code: %d response: %@", statusCode, operation.responseString);
    if (operation.response.statusCode == 402) {
        [self.delegate paymentRequired:true];
        return ;
    }
    [self handleOperationFailed:operation action:^{
        [self determinePaymentRequired];
    }];
}];

控制台中的产量

status code: 200 response: {'payment_required':'false'}

为什么会这样？

根据我的经验，您需要满足 3 个条件才能成功:

1. 200响应代码
2. 响应中包含适当的JSON对象
3. 响应的 Content-Type 设置为 application/json

希望对您有所帮助。
