在nodejs的请求模块中发送大的xml

我有一个非常大的xml使用wsjs节点模块生成。 看起来像

当我发送这个请求使用node.js的请求模块

 request.post({ url: ctx.url, body: ctx.request, headers: { "SOAPAction": ctx.action, "Content-Type": ctx.contentType, "ContentLength": Buffer.byteLength(ctx.request), "MIME-Version": "1.0", "Connection": "Keep-Alive", "AcceptEncoding": "gzip" }, encoding: null, rejectUnauthorized: true, agentOptions: ctx.agentOptions }, function(error, response, body) { ctx.response = body if (response) { ctx.resp_headers = response.headers ctx.resp_contentType = response.headers["content-type"] } if (error) ctx.error = error else ctx.statusCode = response.statusCode callback(ctx) }) 

ctx.request中有整个XML作为1大string我总是得到授权失败的错误,因为端点是正确地拒绝我的请求。 但是,如果我把XML,并把它放在SOAPUI和格式xml然后我得到正确的结果。 所以我得出结论,因为我发送身体为1大xml的端点不喜欢我的要求。 什么是这个解决方法? 有没有其他可用的节点模块可以格式化xml或将其分解成小string?
