$data['thirdSkus'] 不是一个json 不能json_decode
报错：json_decode() expects parameter 1 to be string, array given

@锦瑟_华年: 把 $data打印下呢？

@Cheney.Zhong.ZCY: array(6) {
["thirdSpuId"] => string(5) "10077"

}

@锦瑟_华年:
改为直接赋值

@Cheney.Zhong.ZCY:
直接赋值之后 这个双引号就不见了
"saleAttributes":[{"aid":"10748","vid":"121619","aName":"\u590d\u5370\u7eb8\u89c4\u683c","vName":"B5"}]}

但是
thirdSkus 是还string类型

@锦瑟_华年:
$data["thirdSkus"] 的结构应该如下：

$data["thirdSkus"] = array(
            'thirdSkuId' => '10077',
            'skuName' => '河南鼎铧科贸商品测试新增3',
            'sellPrice' => '163.00',
            'marketPrice' => 195.6,
            'skuType' => 1,
            'primaryImage' => 'https://img14.360buyimg.com/n0/jfs/t1/63929/37/643/505682/5cecf5beEbebd72c6/ff6968ffc1256f4f.jpg',
            'otherImage' => 'https://img14.360buyimg.com/n0/jfs/t1/63929/37/643/505682/5cecf5beEbebd72c6/ff6968ffc1256f4f.jpg',
            'saleAttributes' => array(array(
                'aid' => '10748',
                'vid' => '121619',
                'aName' => '复印纸规格',
                'vName' => 'B5',
            ))
        );
var_dump(json_encode($data['thirdSkus']));

另外：

aid, vid, thirdSkuId 等，如果 java 定义的不是 string， 还是无法解析。

你需要把 aid, vid 等转成 int, price 转成 float 后再调用 json_encode

@Cheney.Zhong.ZCY: 打印出还是string的类型
打印信息如下：
string(513) "{"thirdSkuId":"10077","skuName":"\u6cb3\u5357\u9f0e\u94e7\u79d1\u8d38\u5546\u54c1\u6d4b\u8bd5\u65b0\u589e3","sellPrice":"163.00","marketPrice":195.6,"skuType":1,"primaryImage":"https://img14.360buyimg.com/n0/jfs/t1/63929/37/643/505682/5cecf5beEbebd72c6/ff6968ffc1256f4f.jpg","otherImage":"https://img14.360buyimg.com/n0/jfs/t1/63929/37/643/505682/5cecf5beEbebd72c6/ff6968ffc1256f4f.jpg","saleAttributes":[{"aid":"10748","vid":"121619","aName":"\u590d\u5370\u7eb8\u89c4\u683c","vName":"B5"}]}"
array(4) {
["success"] => bool(false)
["resultCode"] => string(2) "99"
["resultMsg"] => string(479) "JSON parse error: Cannot deserialize instance of java.util.ArrayList out of START_OBJECT token; nested exception is com.fasterxml.jackson.databind.exc.MismatchedInputException: Cannot deserialize instance of java.util.ArrayList out of START_OBJECT token

["result"] => NULL
}

@Cheney.Zhong.ZCY: 你打印出来的是对的吗？是不是我的数组里面的数据类型不对。我打印看一下

已经解决 谢谢你
