Question

我在php脚本中收到一个有趣格式化的$ _POST提交，其格式为：

{"receipt-data":"MILGDgYJKoZIhvcNAQcCoILF..."}

如果我打印$ _POST变量，我得到一个Array（），有时候空的时候包含一个字典“receipt-data”：“....”（我还是不明白为什么有时候它是空的，有时候不）。在它开始空无一人之前，我尝试打印第一个元素，但没有任何有趣的东西。

简单来说，拦截此类发布并获取与收据数据相对应的值的正确方法是什么？

这是（相当长的）发布数据，我为了保持最大消息限额而取消了一些块：

解析时使用：

$json=json_encode($_POST);
$data=json_decode($json, TRUE);

$ data采用以下形式：

这是执行objective-c代码的结果：

NSMutableURLRequest *theRequest = [NSMutableURLRequest requestWithURL:storeURL];
    [theRequest setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];
    NSError *error;
    NSDictionary *requestContents = @{
                                  @"receipt-data": [self.receipt base64EncodedStringWithOptions:0]
                                  };
     NSData *requestData = [NSJSONSerialization dataWithJSONObject:requestContents
                                                      options:0
                                                        error:&error];
    [theRequest setHTTPMethod:@"POST"];
    [theRequest setHTTPBody:requestData];
    NSOperationQueue *queue = [[NSOperationQueue alloc] init];
    [NSURLConnection sendAsynchronousRequest:theRequest queue:queue
                       completionHandler:^(NSURLResponse *response, NSData *data, NSError *connectionError) {
       [...]

通过查看创建请求的代码，我们可以看到它正在发送格式化为JSON的数据，因此您首先要通过json_decode运行它，例如

$data=json_decode($_POST[0], TRUE);

您首先不需要通过json_encode运行它，因为它已经作为JSON发送给您。

然后对于“收据数据”值本身，我们可以看到objective-c代码将其编码为base64，因此您需要使用base64_decode对其进行解码：

$data['receipt-data'] = base64_decode($data['receipt-data']);

解析在PHP中格式化为数组的$ _POST
