我想发送一个字符串＆＃34; hello world＆＃34;通过流到服务器。
到目前为止我做了：

</project>
但不确定我在哪里放置我要发送数据的服务器的IP和端口？
我把我想要发送的字符串放在哪里＆＃34; hello world＆＃34; ？
我在这种方法上遇到错误：

在网址上：无法解析符号网址
private void PostData() {
HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();
try {
urlConnection.setDoOutput(true);
urlConnection.setChunkedStreamingMode(0);
OutputStream out = new BufferedOutputStream(urlConnection.getOutputStream());
writeStream(out);
InputStream in = new BufferedInputStream(urlConnection.getInputStream());
readStream(in);
finally {
urlConnection.disconnect();
}
}
}
在urlConnection.getOutputStream（）未处理的异常。
开启
HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();
无法解析方法writeStream
readStream相同
最后终于：最后没有尝试
我从官方开发者android com：

您可以执行以下操作： -
from selenium.webdriver.chrome.webdriver import WebDriver
import io
csvdoc = "your_path/file.csv"
driver = WebDriver("your_path/chromedriver.exe")
driver.get("http://google.com")
element = driver.find_element_by_id("lst-ib")
with io.open(csvdoc, 'r') as csvfile:
csvcontent = csvfile.read()
print(csvcontent)
for l in csvcontent.splitlines():
line = l.split(',')
element.send_keys(line[0])
element.send_keys(line[1])
element.send_keys(line[2])

你是全新的，因为我可以看到，并且android链接在示例中有一些错误。对于每个＆＃34;网络＆＃34;为你的任务工作，你必须为android异步操作，你还必须为你的清单文件添加网络权限。
例如：
注意：writeStream和readStream是您希望他们完成的工作的自定义函数。
private void PostData() {
String IPPORT = "www.android.com"; // or example 192.168.1.5:80
URL url = new URL("http://"+IPPORT+"/");
HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();
try {
urlConnection.setDoOutput(true);
urlConnection.setChunkedStreamingMode(0);
OutputStream out = new BufferedOutputStream(urlConnection.getOutputStream());
writeStream(out);
InputStream in = new BufferedInputStream(urlConnection.getInputStream());
readStream(in);
}
finally {
urlConnection.disconnect();
}
}
writeStream函数示例
private void writeStream(OutputStream out){
String output = "Hello world";
out.write(output.getBytes());
out.flush();
}

好吧，我担心你必须定义变量“url”和方法“writeStream”和“readStream”。
“url”应该是一个网址对象，其中包含您要连接的地址（您在浏览器中输入的内容），请参阅here。
WriteStream是您将数据写入服务器的地方，也就是您编写“Hello World”的地方。
ReadStream将读取服务器的响应。遗憾的是，在这样的帖子中，阅读和提交数据并不容易解释，但有足够的教程可以帮助您。
答案 3 :(得分：0)
您应该阅读Java中的流，并记住您必须将网络操作放在Android中的单独线程中。
答案 4 :(得分：-1)
I had the same problem but with this code, I can solve
String userAgent = "Mozilla/5.0 (X11; Linux x86_64; rv:26.0) Gecko/20100101 Firefox/26.0";
String address = "http://localhost/form.php";
String forSending = "cadena";
String charset = "UTF-8";
String stringToSend = URLEncoder.encode(forSending, charset);
URL URL = new URL(address);
URLConnection connection = URL.openConnection();
connection.addRequestProperty("User-Agent", userAgent);
connection.setDoOutput(true);
OutputStreamWriter out = new OutputStreamWriter(
connection.getOutputStream());
out.write("nombre=" + stringToSend);
out.close();
BufferedReader in = new BufferedReader(
new InputStreamReader(
connection.getInputStream()));
String response;
while((response = in.readLine()) != null)
System.out.println(response);
in.close();
