Http 415不支持的媒体类型错误与JSON
我正在使用JSON请求调用REST服务,它给出了Http 415不支持的媒体类型错误。
I am calling REST service with JSON request and it gives Http 415 "Unsupported Media Type" error.
请求内容类型设置为(Content-Type,application / json; charset = utf8)。
Request content type is set to ("Content-Type", "application/json; charset=utf8").
如果我在请求中不包含Json对象,它可以正常工作。我正在为json使用google-gson-2.2.4库。
It works fine if I don't include Json object in the request. I am using google-gson-2.2.4 library for json.
我尝试使用几个不同的库,但没有区别。
I tried using a couple of different libraries but it made no difference.
任何人都可以帮我解决这个?
Can anybody please help me to resolve this?
这是我的代码:
public static void main(String[] args) throws Exception
{
JsonObject requestJson = new JsonObject();
String url = "xxx";
//method call for generating json
requestJson = generateJSON();
URL myurl = new URL(url);
HttpURLConnection con = (HttpURLConnection)myurl.openConnection();
con.setDoOutput(true);
con.setDoInput(true);
con.setRequestProperty("Content-Type", "application/json; charset=utf8");
con.setRequestProperty("Accept", "application/json");
con.setRequestProperty("Method", "POST");
OutputStream os = con.getOutputStream();
os.write(requestJson.toString().getBytes("UTF-8"));
os.close();
StringBuilder sb = new StringBuilder();
int HttpResult =con.getResponseCode();
if(HttpResult ==HttpURLConnection.HTTP_OK){
BufferedReader br = new BufferedReader(new InputStreamReader(con.getInputStream(),"utf-8"));
String line = null;
while ((line = br.readLine()) != null) {
sb.append(line + "\n");
}
br.close();
System.out.println(""+sb.toString());
}else{
System.out.println(con.getResponseCode());
System.out.println(con.getResponseMessage());
}
}
public static JsonObject generateJSON () throws MalformedURLException
{
String s = "http://www.abc.com";
s.replaceAll("/", "\\/");
JsonObject reqparam=new JsonObject();
reqparam.addProperty("type", "arl");
reqparam.addProperty("action", "remove");
reqparam.addProperty("domain", "staging");
reqparam.addProperty("objects", s);
return reqparam;
}
}
requestJson.toString的值是:
Value of requestJson.toString is :
{type:arl,action:remove,domain:staging,objects: http://www.abc.com }
{"type":"arl","action":"remove","domain":"staging","objects":"http://www.abc.com"}
不确定原因,但从 con.setRequestProperty删除行
解决了这个问题。 charset = utf8
(Content-Type,application / json; charset = utf8 )
Not sure about the reason but Removing lines charset=utf8
from con.setRequestProperty("Content-Type", "application/json; charset=utf8")
resolved the issue.
