我使用它在本地主机上完美运行的代码，但我试图在我的网络服务器上执行该代码，但在从字符串解析到 JSON 对象时解析其显示错误时没有出错

我的 JSON 解析器代码是

try {
    BufferedReader reader = new BufferedReader(new InputStreamReader(
        is, "utf-8"), 8);
    StringBuilder sb = new StringBuilder();
    String line = null;
    while ((line = reader.readLine()) != null) {
        sb.append(line + "\n");
    }
    is.close();
    json = sb.toString();
    Log.d("converted result", json);
} catch (Exception e) {
    Log.e("Buffer Error", "Error converting result " + e.toString());
}

// try parse the string to a JSON object
try {
    jObj = new JSONObject("{" + json +"}");
} catch (JSONException e) {
    Log.e("JSON Parser", "Error parsing data " + e.toString());
}

// return JSON String
return jObj;

正如错误明确指出的那样，您的 JSON 无效，因为connected它前面的单词。

你需要让你的服务器停止发送这个词。

你有这个 JSON：

{connected{"products":[{"pid":"406355","name":"852610 SOUTHCOUNTYMALL"},{"pid":"406356","name":"852611 SOUTHCOUNTYMALL"},{"pid":"406357","name":"852612 SOUTHCOUNTYMALL"}],"success":1}

这是无效的 JSON 格式，因为您在 JSON 的开头使用了错误的表达式“{connected”。也许，你应该得到这样的 JSON：

{"products":[{"pid":"406355","name":"852610 SOUTHCOUNTYMALL"},{"pid":"406356","name":"852611 SOUTHCOUNTYMALL"},{"pid":"406357","name":"852612 SOUTHCOUNTYMALL"}],"success":1}

或像这样：

{"connected":[VALUE], "products":[{"pid":"406355","name":"852610 SOUTHCOUNTYMALL"},{"pid":"406356","name":"852611 SOUTHCOUNTYMALL"},{"pid":"406357","name":"852612 SOUTHCOUNTYMALL"}],"success":1}

无论如何，我建议您使用 Gson 库来构建和获取 JSON。
