[英]Why does my curl command not work with Java ProcessBuilder API
I want to execute following CURL command from Java: 我想从Java执行以下CURL命令:
curl -v -X PUT --data-binary "@configfile.json" -u username:password -D /tmp/grabbit_headers http:// server:port/grabbit/job
curl -v -X PUT --data-binary“@ configfile.json”-u username:password -D / tmp / grabbit_headers http:// server:port / grabbit / job
(The space between http:// and server... is inserted as per stack overflow guidelines but is not part of my code) (根据堆栈溢出指南插入http://和server ...之间的空格,但不是我的代码的一部分)
I have followed 我跟着
http://alvinalexander.com/java/java-exec-processbuilder-process-1 , process2 and process3 http://alvinalexander.com/java/java-exec-processbuilder-process-1,process2和process3
to create my java classes that use ProcessBuilder API to execute shell commands. 创建使用ProcessBuilder API执行shell命令的java类。
If I execute the CURL command directly on the shell, it works and produces expected results. 如果我直接在shell上执行CURL命令,它会工作并产生预期的结果。 If I use the exact same command via Java classes, it executes without any errors, with exitCode=0, but does not product intended result.
如果我通过Java类使用完全相同的命令,它执行没有任何错误,exitCode = 0,但不产生预期的结果。
Intended result here is to use Grabbit ( https://github.com/TWCable/grabbit ) to migrate content from one Adobe AEM instance to another. 这里的预期结果是使用Grabbit( https://github.com/TWCable/grabbit )将内容从一个Adobe AEM实例迁移到另一个实例。
Here are my primary methods: 这是我的主要方法:
public String processBuilderExample() throws IOException, InterruptedException
{
// build the system command we want to run
List<String> commands;
String result="";
/*
* CURL Commands:
* curl -v -X PUT --data-binary "@$configpath" -u $username:$password -D /tmp/grabbit_headers $client$GRABBIT_JOB > /tmp/grabbit
* */
String curl_command="curl -v -X PUT --data-binary \"@"+this.configpath+"\""+" -u "+this.username+":"+this.password+" -D /tmp/grabbit_headers "+this.client+this.GRABBIT_JOB;
commands = new ArrayList<String>(Arrays.asList(curl_command.split(" ")));
result=runCommand(commands);
return result;
}
//@Override
public String runCommand(List<String> commands) throws IOException, InterruptedException
{
// execute the command
SystemCommandExecutor commandExecutor = new SystemCommandExecutor(commands);
int result = commandExecutor.executeCommand();
// get the stdout and stderr from the command that was run
StringBuilder stdout = commandExecutor.getStandardOutputFromCommand();
StringBuilder stderr = commandExecutor.getStandardErrorFromCommand();
StringBuilder finalReturnString=new StringBuilder();
finalReturnString.append("<br/>STDOUT:<br/>");
finalReturnString.append(stdout.toString());
finalReturnString.append("<br/>STDERR:<br/>");
finalReturnString.append(stderr.toString());
return finalReturnString.toString();
}
Use ProcessBuilder to configure the redirect. 使用ProcessBuilder配置重定向。
">" redirect is part of the shell (sh/bash) and not a command. “>”redirect是shell(sh / bash)的一部分,而不是命令。
Refer to Runtime's exec() method is not redirecting the output on how to use process builder to redirect. 请参阅运行时的exec()方法不会重定向输出,以了解如何使用流程构建器进行重定向。
Refer to &> redirection not working correctly on why it doesn't work. 请参阅&>重定向无法正常工作的原因。
