我发现，我对API的使用是不正确的。正确使用API是

curl -v \
-H 'Authorization: Bearer ya29.GlxSB9-EiDh1Mn2EqhCslHvkaGyOX-P4_yDR4MXOt-WdHYQdFfwUJNMfljAFzZfS-YrrATUU2MAKj3R4BcMyOSw55KjJOC0EekE_qusj8GXIxFF3uaGZxGMdlB0IlQ' \
-H 'Content-Type: application/json' \
-X PUT \
-d '{"range": "Sheet1!A1:D5","majorDimension": "ROWS","values": [["Item", "Cost", "Stocked", "Ship Date"], ["Wheel", "$20.50", "4", "3/1/2016"], ["Door", "$15", "2", "3/15/2016"], ["Engine", "$100", "1", "30/20/2016"], ["Totals", "=SUM(B2:B4)", "=SUM(C2:C4)", "=MAX(D2:D4)"]]}' \
https://sheets.googleapis.com/v4/spreadsheets/1mHrPXQILuprO4NdqTgrVKlGazvvzgCFqIphGdsmptD8/values/Sheet1!A1:D5?valueInputOption=USER_ENTERED

需要注意的要点是

• valueInputOption=USER_ENTERED。我不得不告诉API解析输入，这样USER_ENTERED就成为文档中的有效值
• 由于有效负载是有效的json内容，因此需要使用-H 'Content-Type: application/json'。
• 使用-d选项发送有效负载。
  更正后，我就可以点击API并获得响应

我收到以下错误

curl: (3) nested brace in URL position 8:

{查找所有事务处理文件{id文件名}}}'
好吧，这可能与您的服务器消息“POST body sent invalid JSON."相同，对吗？
现在，当你通过在外部使用双引号并转义内部的双引号来修复json数据时，它应该可以工作：

curl -v -d "{\"query\": \"{findAllTransactionFile {id fileName}}\"}" -H "Content-Type:application/json" http://localhost:8080/apis/graphql

如果您有带大括号的查询参数，则可以使用以下格式：

curl -X PUT \
https://sheets.googleapis.com/v4/spreadsheets/1mHrPXQILuprO4NdqTgrVKlGazvvzgCFqIphGdsmptD8/values/Sheet1\!A1:D5\ \
 --data-urlencode '{"range": "Sheet1!A1:D5","majorDimension": "ROWS","values": [["Item", "Cost", "Stocked", "Ship Date"], ["Wheel", "$20.50", "4", "3/1/2016"], ["Door", "$15", "2", "3/15/2016"], ["Engine", "$100", "1", "30/20/2016"], ["Totals", "=SUM(B2:B4)", "=SUM(C2:C4)", "=MAX(D2:D4)"]]}'

其中--data-urlencode告诉curl对URL进行编码，这样就不会有任何嵌套的大括号
