【问题描述】：

我正在尝试为我的应用程序创建忘记密码脚本。当我运行我的 apk 并尝试恢复我的密码时，我收到错误消息说 Use JsonReader.setLenient(true) to accept malformed JSON at line 1 column 1 path $错误，在我的 apk 中一切正常，我可以登录并注销或注册，但是当我重置密码时，出现 JsonReader.setLenient(true) 错误。我的 apk json 正在工作并且是正确的。请帮我。我正在分享我的代码。

{
   "operation":"resPassReq",
   "user":{
       "email":"name@example.com"

   }
}

如果请求成功，响应将类似于，

{
  "result": "success",
  "message": "Check your mail for reset password code."
}

为了完成密码重置过程，请求类似于，

{
   "operation":"resPass",
   "user":{
       "email":"name@example.com",
       "code":"bcfqa3",
       "password":"rjamalw"

   }
}

如果请求成功，响应将类似于，

{
  "result": "success",
  "message": "Password Changed Successfully"
}

【问题讨论】：

  • 欢迎来到 Stack Overflow！为了给您一个很好的答案，如果您还没有看过How to Ask，它可能会对我们有所帮助。如果您可以提供minimal reproducible example，它可能也很有用。
  • 你应该分享你得到的错误。您可以通过在 onFailure 回调中将 Log.d(Constants.TAG,"failed"); 替换为 Log.d(Constants.TAG,"failed",t); 来打印它。您可能还想输出call 对象包含的任何相关信息。
  • 我收到此错误 - JsonReader.setLenient(true) 在第 1 行第 1 列路径 $ 错误接受格式错误的 JSON
  • 嗯，很明显，当您重置密码时，API 没有返回 json
  • 请告诉我如何解决它..

【解决方案1】：

解决此错误，以便在 android:JsonReader.setLenient(true) 中使用 Retrofit 2 上传图像以在第 1 行第 1 列路径 $ 错误接受格式错误的 JSON

@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
    if (requestCode ==10) {
        if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
            Intent intent = new Intent(Intent.ACTION_PICK);
            intent.setType("image/*");
            startActivityForResult(intent.createChooser(intent, "Select Image"), 10);
        } else {
            Toast.makeText(this, "you have dont Permisson", Toast.LENGTH_SHORT).show();
        }
        return;
    }
    super.onRequestPermissionsResult(requestCode, permissions, grantResults);
}

    【解决方案2】：

    我遇到过这个问题，终于解决了。

    你必须让你的 API 中的所有 $row 与数据库表中的同名，像这样

        "book_chalet_id" => $row['book_chalet_id'],

    所以表中必须有book_chalet_id列。

    【讨论】：

    • 编辑后我得到另一个错误-> java.lang.IllegalStateException: Expected BEGIN_OBJECT but was STRING at line 1 column 1 path $
    • 在问题中也提供 ServerResponse 类代码。现在，这是 json 解析错误。
    • 您在哪个函数中收到此错误应为 BEGIN_OBJECT 但在第 1 行第 1 列路径 $ 为 STRING，响应是什么
    • 尝试使用 POSTMAN REST API 客户端检查 API。在那里，您将了解您输入的输入和响应。根据这一点，您将了解代码中需要更改的内容。
    • 评论不用于扩展讨论；这个对话是moved to chat。
