问题描述
我无法将数据发布到服务器，并显示错误消息.但是它在curl脚本中工作正常.
Iam unable to post the data to the server, getting error as . But it is working fine in curl script.
Error reading URL

iam在上述代码中做错了什么吗?我需要使用curl脚本发布数据吗?
Do iam doing anything wrong from the above code? DO i need to use curl script to post the data?
推荐答案
好，如 <代码>错误415 已在声明:
Well, as Error 415 is already stating:
415不支持的媒体类型
415 Unsupported Media Type
请求实体具有服务器或资源不支持的媒体类型.例如，客户端将图像上传为image/svg + xml，但是服务器要求图像使用其他格式.
The request entity has a media type which the server or resource does not support. For example, the client uploads an image as image/svg+xml, but the server requires that images use a different format.
在不知道服务器期望您发送给他的规范的情况下，很难说出您丢失了什么.似乎您似乎只想从服务器接收数据而不向他发送任何东西.
Without knowing the specifications of what the server is expecting of you to send him, it's hard to tell what you are missing. It though seems as if you only want to receive data from the server and not send him anything.
通过设置 uc.setRequestProperty("Content-Type"，"application/xml"); ，您可以告诉服务器
By setting uc.setRequestProperty("Content-Type", "application/xml"); you tell the server that you hand him over some XML data (which you don't) and he probably also wouldn't expect this, so he's giving you that error.
当您在POST数据中发送一些Urlencoded数据时，请尝试将其设置为:
As your sending some urlencoded data in your POST data, try setting this to:
uc.setRequestProperty("Content-Type", "application/x-www-form-urlencoded; charset=utf-8");
