从web api 2获取值时出现Json Parse错误(Json Parse Error when getting value from web api 2)
我开发了一个简单的WebAPI 2应用程序，其中包含此get方法：
public HttpResponseMessage Get(int id) { var x = db.TESTS.ToList(); var formatter = new JsonMediaTypeFormatter(); return Request.CreateResponse(HttpStatusCode.OK, x, formatter); }我检查了。 它返回Json值。 我也在Fiddler检查了它。
但是当我想在一个简单的html文件中检索它时，我得到解析错误。 我的Web服务发布在localhost中。
网站服务网址： http ： //192.168.5.154/mobileapi/api/values/2正在返回
[{"ID":2.0,"TEXT":"test 2"},{"ID":1.0,"TEXT":"test"}]这是代码。
<!doctype html> <html lang="en"> <head> <meta charset="utf-8"> <title>Get Json value from WebAPI url</title> <script src="https://code.jquery.com/jquery-1.10.2.js"></script> </head> <body> <script type="text/javascript"> jQuery(document).ready(function ($) { jQuery.ajax({ type: "GET", url: "http://192.168.5.154/mobileapi/api/values/2?callback=?", contentType: "application/json; charset=utf-8", dataType: "json", success: function (data, status, jqXHR) { alert("data is available"); }, error: function (jqXHR, status) { alert(status); } }); }); </script> </body> </html>I have developed a simple WebAPI 2 application which include this get method:
public HttpResponseMessage Get(int id) { var x = db.TESTS.ToList(); var formatter = new JsonMediaTypeFormatter(); return Request.CreateResponse(HttpStatusCode.OK, x, formatter); }I checked. It is returning Json value. I also checked it in Fiddler.
But when I want to retrieve this in a simple html file, I am getting parse error. My Web Service is published in localhost.
Web service url: http://192.168.5.154/mobileapi/api/values/2 is returning
[{"ID":2.0,"TEXT":"test 2"},{"ID":1.0,"TEXT":"test"}]Here's the code.

最满意答案
琐碎但不便携的方式：
subprocess.call(["/bin/sh","-c","cat File | grepcidr -f file.name >>output.file"])它需要
/bin/sh，如果依赖cat，这应该不是问题。 我认为可以自己构建一个合作子进程系列：你必须做/bin/sh对管道和重定向的处理，但是在python中。Trivial but non-portable way:
subprocess.call(["/bin/sh","-c","cat File | grepcidr -f file.name >>output.file"])It requires
/bin/sh, which should not be a problem if you rely oncatanyway. I think it's possible to build a family of cooperating subprocesses yourself: you'd have to do what/bin/shdoes with pipes and redirections, but in python.
