来自GoLang中GetDocumentAnalysis的AWS Textract键值对

I am calling AWS Textract GetDocumentAnalysisRequest on a PDF document which I sent to Textract, which returns blocks of data. Then I am trying to convert the data into a key value map. The document was analyzed for FORM and TABLES. I was trying to port the example code provided in python into go to convert the blocks into KV Maps (https://github.com/awsdocs/aws-doc-sdk-examples/blob/master/python/example_code/textract/textract-python-kv-parser.py). It was working fine in python. In my code there are random spaces in the keys and values. I am assuming its due to this line in the code text = fmt.Sprintf("%s %s", text, *word.Text).

// Contains tells whether a contains x.
func Contains(a []*string, x string) bool {
    for _, n := range a {
        if x == *n {
            return true
        }
    }
    return false
}

    KeyMap   map[string]textract.Block

    keyMap := map[string]textract.Block{}

    for _, block := range blocks {
        blockID := block.Id
        blockMap[*blockID] = *block

        if *block.BlockType == textract.BlockTypeKeyValueSet {

            if Contains(block.EntityTypes, textract.EntityTypeKey) {
                keyMap[*blockID] = *block
            } else {
