我必须使用proxyHost和proxyPort设置代理以使用POST发送JSON。
public static final MediaType JSON = MediaType.parse("application/json; charset=utf-8");
Proxy proxyTest = new Proxy(Proxy.Type.HTTP,new InetSocketAddress("proxy", proxyPort));
OkHttpClient client = new OkHttpClient()
.proxy(proxyTest)
.build();
//OkHttpClient.Builder builder = new OkHttpClient.Builder();
//builder.proxy(proxySAP);
//client.setProxy(proxySAP)
//OkHttpClient client = builder.build();;
String post(String url, String json) throws IOException {
RequestBody body = RequestBody.create(JSON, json);
Request request = new Request.Builder()
.url(url)
.post(body)
.build();
try (Response response = client.newCall(request).execute()) {
return response.body().string();
}
}
当我尝试使用我在一些答案上看到的proxyTest时,它指出了一个错误:
OkHttpClient类型中的方法proxy()不适用于 参数(代理)
我使用OKHTTP 3.3.1(okhttp3)
我的问题是,我该怎么办?我做了一些像这样的测试:
OkHttpClient.Builder builder = new OkHttpClient.Builder();
builder.proxy(proxyTest);
client.setProxy(proxyTest)
OkHttpClient client = builder.build();
但到目前为止没有任何作用。
谢谢你的时间!

找到解决方案:
//OkHttpClient client = new OkHttpClient();
OkHttpClient.Builder builder = new OkHttpClient.Builder().proxy(proxyTest);
OkHttpClient client = builder.build();
//builder.proxy(proxyTest);
//client.setProxy(proxyTest)
//OkHttpClient client = builder.build();;
如果我们使用构建器输入代理,它将像charm = D
一样工作最诚挚的问候!

okhttp版本:3.11.0
。 SOCKS代理示例
String hostname = "localhost"/*127.0.0.1*/;
int port = 1080;
Proxy proxy = new Proxy(Proxy.Type.SOCKS,
new InetSocketAddress(hostname, port));
OkHttpClient client = new OkHttpClient.Builder()
.proxy(proxy)
.build();

SOCKS5身份验证示例
我认为这是最简单的工作解决方案。但是在我看来,它可能不是100%安全的。我从此代码from here中获取了此代码,并对其进行了修改,因为我的代理的RequestorType是SERVER。 实际上,java对于代理有一个奇怪的api,您应该通过系统env为代理设置auth(您可以从同一链接中看到它)
final int proxyPort = 1080; //your proxy port
final String proxyHost = "your proxy host";
final String username = "proxy username";
final String password = "proxy password";
InetSocketAddress proxyAddr = new InetSocketAddress(proxyHost, proxyPort);
Proxy proxy = new Proxy(Proxy.Type.SOCKS, proxyAddr);
Authenticator.setDefault(new Authenticator() {
@Override
protected PasswordAuthentication getPasswordAuthentication() {
if (getRequestingHost().equalsIgnoreCase(proxyHost)) {
if (proxyPort == getRequestingPort()) {
return new PasswordAuthentication(username, password.toCharArray());
}
}
return null;
}
});
OkHttpClient client = new OkHttpClient.Builder()
.proxy(proxy)
.build();
