json_decode 解析不了数据

[mahuatengBC]

代码大概如下，是通过流方式获取的json

string(342) "{"amount":1,"payChnl":"bank","orderNo":"15023608033500010018","signature":"b70f8689e00cbb2df9c943574ed6ade6","subject":"充值","openId":"","fee":0,"description":"","body":"充值","paidTime":1502360832854,"paySt":2,"orderDt":"20170810","appid":"0000005025","extra":"","mchntId":"0000002087","mchntOrderNo":"fd943fdd9d0e45c088a83c9b8a6d27d9"}"

dump 出来的数据是这样的，但是使用json_decode函数之后，一直返回空？

试过编码问题，还是不行，不知道哪里出了问题。求大神解答

不知道你要干什么？那些截图只表示你不知道如何将数组的字面表示保存到文件中去 print_r 和 var_export 的第二个参数为 true 时，返回的就是数组格式化后的字符串

[hongmei85]

估计问题出在ob_get_clean \ob_end_clean，这两函数把字符都搞没了， $result2 = ob_get_clean()，是ob_get_clean把字符搞没的 $result = json_encode($res)才是正常结果，别把几个变量$result、$result2、$res看花眼了

根据你贴的json,没问题。

$s = '{"amount":1,"payChnl":"bank","orderNo":"15023608033500010018","signature":"b70f8689e00cbb2df9c943574ed6ade6","subject":"充值","openId":"","fee":0,"description":"","body":"充值","paidTime":1502360832854,"paySt":2,"orderDt":"20170810","appid":"0000005025","extra":"","mchntId":"0000002087","mchntOrderNo":"fd943fdd9d0e45c088a83c9b8a6d27d9"}';
print_r(json_decode($s, true));

Array ( [amount] => 1 [payChnl] => bank [orderNo] => 15023608033500010018 [signature] => b70f8689e00cbb2df9c943574ed6ade6 [subject] => 充值 [openId] => [fee] => 0 [description] => [body] => 充值 [paidTime] => 1502360832854 [paySt] => 2 [orderDt] => 20170810 [appid] => 0000005025 [extra] => [mchntId] => 0000002087 [mchntOrderNo] => fd943fdd9d0e45c088a83c9b8a6d27d9 )

json_decode() 第二个 参数 为 true 才会返回数组

[mahuatengBC]

我把打印出来的json 用json格式化，也没问题啊，但是用json_decode 就不行啊。可能会是什么情况？ 有bom头？

[mahuatengBC]

现在是没有返回值，不是返回对象，还是数组的问题啊，是没有返回值啊！！！

[一起混吧]

json_decode 只支持utf-8编码，所以检查一下编码，还要确认无bom头

[xuzuning]

echo base64_encode($res); 或先写到文件，贴出结果！

[mahuatengBC]

已经写入文件了啊，json也贴出来了。关键是json_decode 之后没有值

引用 7 楼 xuzuning 的回复:

echo base64_encode($res); 或先写到文件，贴出结果！

我打印了 base64_encode($res); 结果如下 eyJhbW91bnQiOjEsInBheUNobmwiOiJiYW5rIiwib3JkZXJObyI6IjE1MDI0MjE4Nzg1MzMwMDEwMTc3Iiwic2lnbmF0dXJlIjoiMDdkYzdjMmVhNDVhMmVmNDJlOGI1YTFhNDMyYTU3OWMiLCJzdWJqZWN0Ijoi5YWF5YC8Iiwib3BlbklkIjoiIiwiZmVlIjowLCJkZXNjcmlwdGlvbiI6IiIsImJvZHkiOiLlhYXlgLwiLCJwYWlkVGltZSI6MTUwMjQyMTkwODI2NCwicGF5U3QiOjIsIm9yZGVyRHQiOiIyMDE3MDgxMSIsImFwcGlkIjoiMDAwMDAwNTAyNSIsImV4dHJhIjoiIiwibWNobnRJZCI6IjAwMDAwMDIwODciLCJtY2hudE9yZGVyTm8iOiI4OWZlZjdmNjYxZTE0OTYxOTlhMTMxYjk5YTJkY2ZiMyJ9 这个能看出啥？

并无任何问题，显然你是画蛇添足了

[mahuatengBC]

我就问 ，我json_decode 返回空，该怎么解释

[mahuatengBC]

试了三种方法，

打印出来的分别是这样的

直接 用 $result = json_decode(file_get_contents("选择读取文件的路径")) 这个 方法 试试 ~ 不要用 变量 接收 file_get_contents("") 的结果 在用 json_decode 转换， /*$res = file_get_contents(""); $resulet = json_decode($res);*/ 这个直接 合并 成 $result = json_decode(file_get_contents("选择读取文件的路径"))； 试试~~
