Let's look at the error you are receiving.
让我们看看您收到的错误。
Expected BEGIN_OBJECT
预期 BEGIN_OBJECT
Your JSON is an object, and all JSON objects are enclosed in curly braces ({}). BEGIN_OBJECT is therefore {. And it's expecting it somewhere.
您的 JSON 是一个对象，所有 JSON 对象都包含在花括号 ({}) 中。因此 BEGIN_OBJECT 是 {。它正在某处期待它。
but was STRING
但是是STRING
But instead he found a string "Something". Still doesn't tell us where.
但相反，他发现了一个字符串“Something”。仍然没有告诉我们在哪里。
at line 1 column 1 path $
在第 1 行第 1 列路径 $
Ah, perfect. At line 1 column 1. Which is the start of the JSON. So you have forgotten to enclose the whole thing in {} (or at least you have forgotten the first one, but I bet you've forgotten them both).
啊，完美。在第 1 行第 1 列。这是 JSON 的开始。因此，您忘记将整个内容包含在 {} 中（或者至少您忘记了第一个，但我敢打赌您已经忘记了它们）。
