HTTP响应显示Accept=multipart/form数据，但未设置此标头并设置AcceptContentType“application/json”

Question

我不是在请求中设置Accept=multipart/form数据，而是设置交换。getIn（）。setHeader（“CamelAcceptContentType”、“application/json”）；交换。getIn（）。setHeader（“内容类型”、“应用程序/json”）；

响应为Accept=multipart/form data CamelHttpMethod=POST、CamelHttpResponseCode=415、CamelHttpResponseText=Unsupported媒体类型

服务器似乎告诉我它正在向我发送一个多部分表单数据媒体类型，但是，我告诉它我正在寻找应用程序/json。

我没有在请求中发送多部分表单数据。有人能解释一下这是怎么回事吗？非常感谢。服务器是否正在设置此选项？

StringBuilder authHeader = new StringBuilder("Bearer ");
authHeader.append(token);
LOG.info("Authorization: " + authHeader.toString());

exchange.setProperty("CamelCharsetName", "UTF-8");  //"CamelCharsetName" Exchange.CHARSET_NAME
exchange.getIn().setHeader("CamelHttpCharacterEncoding", "UTF-8");   //"CamelHttpCharacterEncoding" Exchange.HTTP_CHARACTER_ENCODING
exchange.getIn().setHeader("CamelAcceptContentType", "application/json");  //"CamelAcceptContentType" Exchange.ACCEPT_CONTENT_TYPE
exchange.getIn().setHeader("CamelHttpUri", uploadUrl);  //"CamelHttpUri" Exchange.HTTP_URI
exchange.getIn().setHeader("CamelHttpMethod", "POST");  //"CamelHttpMethod" Exchange.HTTP_METHOD
exchange.getIn().setHeader("x-ge-csvformat", "ODB");
exchange.getIn().setHeader("Tenant", tenant);
exchange.getIn().setHeader("Content-Type", "application/json"); // for JSON ONLY comment for CSV
exchange.getIn().setHeader("Authorization", authHeader.toString());

我想问题应该是为什么我会得到一个带有Accept=multipart/form数据的响应头？当我没有设置或使用多部分/表单数据时？

这里是超文本传输协议发布请求。

这里是服务器响应——请注意响应消息开头的Accept=multipart/form=data。

Answer 1

好的，这就是云环境配置的机制。

服务器URL有2个endpoint，1个用于多部分表单数据，1个用于JSON。我发布到CSV多部分表格数据。

https://apm-ts-ingestion-svc-prod.app-api.aws-usw02-pr.px.io/v2/ts/upload-CSV多部分https://apm-ts-ingestion-svc-prod.app-api.aws-usw02-pr.px.io/v2/ts-JSON

因此，答案是肯定的，因为服务器的响应让我知道它期望或能够用什么进行通信。学习很有趣-谢谢！！
