FormatException:输入的意外结束(在字符1处)

问题描述：

我正在尝试从json解析数据，但是出了点问题. 终端控制台说:

I'm trying to parse data from json but something is wrong. Terminal console says:

Performing hot restart...
Restarted application in 1.659ms.
I/flutter ( 9594): Load xd en
I/flutter ( 9594): Exception: FormatException: Unexpected end of input (at character 1)
I/flutter ( 9594):
I/flutter ( 9594): ^
I/flutter ( 9594): /0
I/flutter ( 9594): error: 0

可以在这里找到我的json:链接

My json can be found here: link

但是在这个链接上，当我尝试从json解析数据时，它可以工作，而且两个json看起来都一样. (在这一点上，我无权访问PHP文件)

But at this link it works when I try to parse data from json, and both json's looks same. ( at this one I do not have access to PHP file)

我像往常一样进行json打印，

I did json print as usually, like this:

$myJson = ['op'=>true,'msg'=>'','data'=>['pages'=>3538,'page'=>(int)$stranica,'news'=>$api]];
        print_r(json_encode($myJson));

关于此是否有任何窍门/技巧?我想念什么吗?

Is there any trick/hack about this? Am I missing something?

答

一直在努力解决同样的错误... 触发POST req有什么奇怪的地方，但是无论如何都抛出了异常.

been struggling wit the same error since yesterday... whats strange that POST req is fired, but the exception was thrown anyway..

在我的情况下，问题是返回响应的临时功能之一:

in my case, the problem was one of the temporary functions returning the response:

//      Response registerResponse = await dio.post(Strings.USER_REGISTER_URL, data: requestBody, options: new Options(contentType: ContentType("application", "json")));


//      print(TAG + registerResponse.toString());
//      print(TAG + registerResponse.data.toString());
//      Map<String, dynamic> parsedregisterResponse = jsonDecode(registerResponse.data);
//      print(TAG + "response: " + parsedregisterResponse.toString());

用于监视输出-将在今天晚上找出哪一个(可能是Map)，并告知您.同时，请重新检查您的响应类型并解码-就像我的情况一样，它肯定有问题.

used to monitor the output - will find out which one (probably Map) this evening and let u know. In the meantime recheck your response type and decoding -there must be something wrong with it just like in my case.
