[英]Unable to send JSON string through java Runtime.getRuntime.exec();
I'm trying to send a JSON string using CURL command and Runtime.getRuntime.exec() function. 我正在尝试使用CURL命令和Runtime.getRuntime.exec()函数发送JSON字符串。
My JSON string is something like: 我的JSON字符串类似于:
String jsonString = "{\"object\":[\"something\",\"another something\"]}"
I'm trying to send this string using the following function: 我正在尝试使用以下功能发送此字符串:
Process p;
p = Runtime.getRuntime().exec(new String[] {"curl","someURL","-H","Content-Type:application/json","-d",jsonString,"-u","something:something"}
Once I execute the following lines and parse the output, I get an error saying that the JSON document is not valid. 一旦执行以下行并解析了输出,就会收到一条错误消息,指出JSON文档无效。 When I try the same command using command line, it works just fine.
当我使用命令行尝试相同的命令时,它工作正常。 I think the problem is with the JSON string as the escape characters are also being send as a part of the JOSN data and hence the invalid JSON data output.
我认为问题在于JSON字符串,因为转义字符也作为JOSN数据的一部分发送,因此无效的JSON数据输出也已发送。
Is there anything that I have done wrong or is there any other way that I have to execute the command. 是否有我做错的事情,或者我必须执行命令的其他方式。
Just tried like with a modification and worked 只是尝试像修改并工作
String jsonString = "{\"object\":[\"something\",\"another something\"]}";
ProcessBuilder ps = new ProcessBuilder(new String[] { "curl", "http://localhost:8338", "-H",
"Content-Type:application/json", "-d", jsonString, "-u", "something:something" });
ps.redirectErrorStream(true);
Process pr = ps.start();
BufferedReader in = new BufferedReader(new
InputStreamReader(pr.getInputStream()));
String line;
while ((line = in.readLine()) != null) {
System.out.println(line);
}
pr.waitFor();
in.close();
System.exit(0);
For server side I used Pippo webframework and it returned me an OK string 对于服务器端,我使用了Pippo webframework,它返回了一个OK字符串

OK
Server side code: 服务器端代码:
public class PippoApplication extends Application {
private final static Logger log = LoggerFactory.getLogger(PippoApplication.class);
@Override
protected void onInit() {
POST("/", new RouteHandler() {
@Override
public void handle(RouteContext routeContext) {
System.out.println(routeContext.getRequest().getBody());
routeContext.send("OK");
}
});
}
} }
