我使用谷歌自然語言來檢測實體情緒,發送Ajax調用https://language.googleapis.com/v1/documents:analyzeEntitySentiment總是返回錯誤400,我的Ajax調用如下,Google自然語言REST API返回錯誤400收到無效的JSON有效內容。未知名「文件」:「
{
APIKEY = '**********************';
$.ajax({
type : "POST",
url : "https://language.googleapis.com/v1/documents:analyzeEntitySentiment?key="+APIKEY,
ContentType : "application/json",
data : {
"document": JSON.stringify(
{ "type":"PLAIN_TEXT",
"content":"Nature is so beautiful"
}),
"encodingType":"UTF8"
},
success : function(_result){
if (_result) {
alert('SUCCESS');
}else{
alert('ERROR');
}
},
error : function(_result){
alert(_result);
}
});
和錯誤:如在實況提到
"code": 400,
"message": "Invalid JSON payload received. Unknown name \"document\": Cannot bind query parameter. 'document' is a message type. Parameters can only be bound to primitive types.",
"status": "INVALID_ARGUMENT",
"details": [
{
"@type": "type.googleapis.com/google.rpc.BadRequest",
"fieldViolations": [
{
"description": "Invalid JSON payload received. Unknown name \"document\": Cannot bind query parameter. 'document' is a message type. Parameters can only be bound to primitive types."
}
]
}
]
應使用「文檔」作爲請求主體數據。
提前致謝!
