我試圖使用Java Apache HttpClient發送多部分POST請求,以將某些測試數據導入到BigQuery表中,但我一直收到HTTP 400錯誤消息「Invalid Upload Request 」。我很確定我很好地遵循BigQuery教程來重現所需,但不起作用。有人可以看看這個請求,看看它是否有什麼問題嗎?POST中的「無效上傳請求」
String rawInput = "--xxx\n";
rawInput += "Content-Type: application/json; charset=UTF-8\n";
rawInput += "{\n";
rawInput += "'configuration': {\n";
rawInput += "'load': {\n";
rawInput += "'schema': {\n";
rawInput += "'fields': [\n";
rawInput += "{'name':'field1', 'type':'STRING'},\n";
rawInput += "{'name':'field2', 'type':'STRING'},\n";
rawInput += "{'name':'field3', 'type':'STRING'},\n";
rawInput += "{'name':'field4', 'type':'STRING'},\n";
rawInput += "]\n";
rawInput += "},\n";
rawInput += "'destinationTable': {\n";
rawInput += "'projectId': 'xxxxxxxxxxx [redacted]',\n";
rawInput += "'datasetId': 'test',\n";
rawInput += "'tableId': 'test'\n";
rawInput += "}\n";
rawInput += "createDisposition = CREATE_IF_NEEDED\n";
rawInput += "}\n";
rawInput += "}\n";
rawInput += "}\n";
rawInput += "--xxx\n";
rawInput += "Content-Type: application/octet-stream\n";
rawInput += "\n";
rawInput += "1,1234,11111111,1\n";
rawInput += "2,5678,11111111,1\n";
rawInput += "3,9101,11111111,1\n";
rawInput += "4,6543,11111111,1\n";
rawInput += "--xxx--";
請求,然後像這樣執行:
postRequest.addHeader("Content-Type", "multipart/related; boundary=xxx;");
postRequest.addHeader("Authorization", "OAuth " + credential.getAccessToken());
StringEntity input = new StringEntity(rawInput);
postRequest.setEntity(input);
HttpResponse response = httpClient.execute(postRequest);
另外,如果我改變的addHeader( 「Content-Type的」 ......)的addHeader來( 「內容類型:」 .. ),錯誤更改爲「Media type'text/plain'不支持。有效媒體類型:[application/octet-stream]」。
我在使用node.js執行多部分文章時遇到同樣的問題。你有沒有發現問題是什麼? – Gus
@Gus:不,不幸的是我沒有,而且我已經開始了另一個項目,所以我不再追求這個問題。我希望你找到/找到了解決方案! –
