我构建了一个带有http://sparkjava.com/的http服务器，用于验证文件是否有效。
代码非常简单：
post("/pdf", (req, res) -> {
if (req.headers("application/pdf") == null) {
res.status(400);
PdfState state = new PdfState();
state.SetIsValid(false);
return JsonUtil.toJson(state);
}
InputStream stream = new ByteArrayInputStream(req.bodyAsBytes());
PdfState state = pdf.validate(stream);
res.type("application/json");
return JsonUtil.toJson(state);
});
然后我想编写单元测试并选择http客户端库http://square.github.io/okhttp/。
测试功能如下：
public void IsPdfContentRequestValid_StreamValidPdfContent_ExpectJsonSuccess() throws Exception {
File file = new File("/Volumes/Dev/java/inspector/files/pass.pdf");
Request request = new Request.Builder()
.url("http://127.0.0.1:3000/pdf")
.addHeader("Content-type", "application/pdf")
.post(RequestBody.create(MEDIA_TYPE_MARKDOWN, file))
.build();
Response response = client.newCall(request).execute();
if (!response.isSuccessful()) throw new IOException("Unexpected code " + response);
System.out.println(response.body().string());
}
当我运行测试时，它会抱怨：
java.net.ConnectException: Failed to connect to /127.0.0.1:3000
OKClient有什么问题？
更新
这就是整个错误：
