英文:
Set processOptions for doc ai ocr api request
问题
我们建议在我们的OCR处理器上激活一个标志以获得更好的结果，因为我们面临一些问题（比如 "I" 被解析为 "1"）。为了测试这个标志，我想使用Postman，但是在我的请求中添加选项会导致错误。
我的请求：
{
"skipHumanReview": true,
"processOptions": {
...
},
"rawDocument": {
"mimeType": "application/pdf",
"content": "..."
},
"fieldMask": "text,pages.blocks,pages.paragraphs,pages.formFields"
}
在没有 processOptions 部分的情况下，请求运行正常。但是 processOptions 未被识别。结果如下：
{
...
"message": "Invalid JSON payload received. Unknown name \"processOptions\": Cannot find field."
...
}
所使用的处理器版本是 pretrained-ocr-v1.2-2022-11-10。我不知道是否使用了错误的版本（我看到的是最新的版本），还是我的请求有问题（我没有找到带有此标志的示例）。在我们的应用程序中，我们不使用提供的包，而是使用自定义代码（APEX）构建请求，因此我使用那种方式也会遇到同样的问题。
更新：
我找到了一些示例，我确信我的请求是正确的。那么我猜这必须是版本的问题，但 pretrained-ocr-v1.2-2022-11-10 是我可以获取到的最新版本。
有人能解释为什么吗？
英文:
We are recommended to activate a flag on our OCR processor for better results because we face some problems (like "I" parsed as "1". To test the flag I want to use Postman, but adding the options to my requests results in an error.
My Request:
{
"skipHumanReview": true,
"processOptions": {
...
},
"rawDocument": {
"mimeType": "application/pdf",
"content": "..."
},
"fieldMask": "text,pages.blocks,pages.paragraphs,pages.formFields"
}
Without the processOptions part, the requests works fine. ProcessOptions is not recognized. The Result is:
{
...
"message": "Invalid JSON payload received. Unknown name "processOptions": Cannot find field."
...
}
The processor version used is pretrained-ocr-v1.2-2022-11-10
I don't know if I have a wrong version (the one used is the newest I see) or if my request is wrong (I didn't find an example with this flag).
In our application we don't use the provided packages, but build the requests with custom code (APEX), so I will have the same problem using that.
Update:
I found some examples and I am sure, that my request is correct. Then I guess it has to be the version, but pretrained-ocr-v1.2-2022-11-10 is the newset one I get offered
Can somebody explain why?

目前，只有在使用 v1beta3 终端时才能指定 ProcessOptions。 https://documentai.googleapis.com/v1beta3
此文档显示如何将该字段添加到 processRequest。
此 Python 示例显示如何向 ocr_config 添加一些选项，一旦这些选项添加到 v1 终端中，官方示例将会更新以包括此字段。

英文:
Currently, ProcessOptions can only be specified when using the v1beta3 endpoint. https://documentai.googleapis.com/v1beta3
This documentation shows how to add the field to the processRequest
This Python sample shows how to add some options to ocr_config the official samples will be updated to include this field once the options are added to the v1 endpoint.
