java - 如何为所有请求设置默认标题？

我有很多要求。如何为所有请求设置默认标题？请给我例子

现在，我的代码如下所示：

    HttpPost request = new HttpPost(url);
    StringEntity params = null;
    try {
        params = new StringEntity(o.writeValueAsString(auth));
    } catch (UnsupportedEncodingException e) {
        e.printStackTrace();
    }
    request.addHeader("content-type", "application/json");
    request.setEntity(params);
    try {
        client = HttpClientBuilder.create().build();
        HttpResponse response = client.execute(request);
    } catch (IOException e) {
        e.printStackTrace();
    }

所以我有很多这样的要求

最佳答案

由于您正在使用HttpClientBuilder，为什么不尝试使用其setDefaultHeaders()方法？

HttpClientBuilder client = HttpClientBuilder.create();
Header header = new BasicHeader(HttpHeaders.CONTENT_TYPE, "application/json");
client.setDefaultHeaders(header);
HttpPost request = new HttpPost(url);
StringEntity params = null;
try {
    params = new StringEntity(o.writeValueAsString(auth));
} catch (UnsupportedEncodingException e) {
    e.printStackTrace();
}
request.setEntity(params);
try {
    client.build();
    HttpResponse response = client.execute(request);
} catch (IOException e) {
    e.printStackTrace();
}

希望有帮助！
