Question

java 怎么获取url接口json数据

Answer 1

String oParams = "Field1=10" ; //设置参数
String url = "/api/SimpleInfoDocumentByField";
HttpClient httpclient = new HttpClient();
httpclient.getHostConfiguration().setHost("192.168.0.231", 7000, "http");
String urlBody = null;
try {
GetMethod getMethod= new GetMethod(url + "?" + oParams);
getMethod.setRequestHeader("Content-type", "text/JSON; charset=UTF-8");

// 链接超时(单位毫秒)
httpclient.getHttpConnectionManager().getParams()
.setConnectionTimeout(3000);
// 读取超时(单位毫秒)
httpclient.getHttpConnectionManager().getParams()
.setSoTimeout(3000);

int statusCode = httpclient.executeMethod(getMethod);
if (statusCode == 200) {
urlBody = getMethod.getResponseBodyAsString();
}
getMethod.releaseConnection();
} catch(Exception e){
e.printStackTrace();
}

还有一种postMethod，自己百度吧。
