根因分析

为整数字段提供的 JSON 值不是有效的整数，导致 protojson 解组失败。

English

The JSON value provided for an integer field is not a valid integer, causing protojson unmarshaling to fail.

解决方案

  1. 90% 成功率 
    // Ensure the JSON field is a number, not a string.
// If it's a string, parse it and set the field manually.
  2. 85% 成功率 
    opts := protojson.UnmarshalOptions{AllowPartial: true}
err := opts.Unmarshal(data, msg)

无效尝试

常见但无效的做法:

  1. 80% 失败

    Changing the type breaks compatibility and may not be semantically correct.

  2. 70% 失败

    Custom parsers are error-prone and don't integrate with protobuf well.
