Question

我正在尝试使用JSON将图像发送到服务器。数据仍然正确，直到我设置我的字典以使用NSJSONSerialization进行编码：我使用的功能：

- (NSData*) getHTTPBody
{
    if ([NSJSONSerialization isValidJSONObject:jsonMessage])
    {
        NSError * error = Nil;
        NSData * jsonData = [NSJSONSerialization dataWithJSONObject:jsonMessage options:0 error:&error];
        NSString *jsonString = [[NSString alloc] initWithData:jsonData encoding:NSUTF8StringEncoding];
        return jsonData;
    }
    return Nil;
}

使用以下输入：

Printing description of self->jsonMessage:
{
    function = addattachment;
    variables =     {
        attachment =         {
            enddate = 1377475200000;

}

这似乎是正确的。事实上，我已经测试了Base64字符串并将其转换回在线解码器，它完美无瑕。

无论如何，生成了JSON NSData对象。从测试目的来看，我将它转换回NSString。这是结果：

原始base64中的所有斜杠（/）都是反斜杠（）转义。因此数据已损坏。有没有让JSONSerialization知道不能逃脱字符串的选项？

非常感谢提前。

这似乎是一个后端问题。

在搜索了两个字符串之后，似乎Base64字符串中有一些变化无法在客户端解析...客户端期望：输出==输入。

用NSJSONSerialization编码的Base64字符串是反斜杠转义的
