java http 500错误怎么解决_java - HTTP POST请求中出现500内部错误

时间:2025-03-11 12:16:22

我正在使用以下代码通过HTTP POST上传文件,但是我从服务器收到500 Internal Server Error响应。

您能否看一下,让我知道哪个代码部分是罪魁祸首/缺失。 HTTPS连接中没有错误,我认为 header 中存在一些问题,因此服务器不接受此请求。// Check server address

url = new URL("");

String protocol = ();

String host = ();

String serviceRoot = ();

// Build POST request

HttpPost post = new HttpPost(new URI(protocol + "://" + host

+ serviceRoot));

("User-Agent", "Test");

("Content-type", "multipart/form-data");

("Accept", "image/jpg");

String authValue = "Basic "

+ Base64

.encodeBase64ToString(("username" + ":"

+ "password").getBytes()) + " " + "realm=\"\"";

if (authValue != null) {

("Authorization", authValue);

}

File file = new File("/sdcard/Download/");

FileBody data = new FileBody(file);

String file_type = "jpg" ;

String description = "Test";

MultipartEntity reqEntity = new MultipartEntity();

("file_name", new StringBody( () ) );

("description", new StringBody(description));

("file_type", new StringBody(file_type));

("data", data);

(reqEntity);

if (true) {

String trace = ">>> Send HTTP request:";

trace += "\n " + () + " "

+ ().getUri();

(trace);

}

if (true) {

String trace = "<<< Send HTTP request-->:";

trace += "\n" + ();

Header[] headers = ();

for (Header header : headers) {

trace += "\n" + () + " " + ();

}

(trace);

}

HttpClient httpClient = createHttpClient();

// replace with your url

// “Authorization”, “Basic ” + encodedUsernamePassword);

if (httpClient != null) {

response = (post);

if (true) {

String trace = "<<< Receive HTTP response:";

trace += "\n" + ().toString();

Header[] headers = ();

for (Header header : headers) {

trace += "\n" + () + " " + ();

}

(trace);

}

} else {

throw new IOException("HTTP client not found");

}

谢谢

最佳答案

500 Internal Server Error是服务器错误,即。问题出在服务器端,而不是客户端。您需要检查服务器日志以查看问题所在。

header 很好。如果标题错误,则会收到400 Bad Request或其他4xx错误。
