org.apache.http.client.methods.HttpPost的使用和坑
依赖的jar包:
<dependency>
<groupId>org.apache.httpcomponents</groupId>
<artifactId>httpclient</artifactId>
<version>4.3.2</version>
</dependency>
如何使用org.apache.http.client.methods.HttpPost 发送请求体呢?
httpPost.setHeader("Content-Type","application/json;charset=UTF-8");
httpPost.setEntity(new StringEntity(json,Constant.CHARSET_UTF));
注意:如果请求体是json,则一定要设置"Content-Type"
否则服务器无法读取到
