Setting RequestBody properly of MockHttpServletRequestBuilder
提问by jlars62
I am simply trying to test a Spring controller method using a MockHttpServletRequestBuilder. The signature of the controller method looks like this:
我只是尝试使用MockHttpServletRequestBuilder. 控制器方法的签名如下所示：
@RequestMapping(value = "/assignTeamsToUsers", method = RequestMethod.POST)
public @ResponseBody String assignUsersToTeams(Model model, @RequestBody MultiValueMap<String, String> ids).
In my test case I have:
在我的测试用例中，我有：
MockMvc mockMvc = MockMvcBuilders.webAppContextSetup(applicationContext).build();
MockHttpServletRequestBuilder request = createRequest(uri, method);
//set up request object...Not sure how??
//My current attempt:
String body = "userIds[]=0&teamIds[]=0";
request.content(body);
request.accept(MediaType.ALL);
request.contentType(MediaType.APPLICATION_FORM_URLENCODED);
ResultActions resultActions = mockMvc.perform(request);
EDIT: Showing createRequest. method= "POST"
编辑：显示 createRequest。method= "发布"
private MockHttpServletRequestBuilder createRequest (String uri, String method) {
MockHttpServletRequestBuilder builder = null;
if("GET".equalsIgnoreCase(method))
builder = MockMvcRequestBuilders.get(uri);
else if("POST".equalsIgnoreCase(method))
builder = MockMvcRequestBuilders.post(uri);
else
Assert.fail("Unsupported method!");
//We always create requests for user Manager
builder.header("securityRole", Role.Manager.getDisplayName());
return builder;
}
I know the uri and method are correct. My problem is I am getting a 415error code from Spring. Basically, I do not know how to set up the requestobject to have the appropriate @RequestBodyfor the MultiValueMap. I have tried alot of variations of setting request.content, setting the request.accept, request.contentType, request.characterEncoding, and still every time I get a 415 error.
我知道 uri 和方法是正确的。我的问题是我从 Spring收到415错误代码。基本上，我不知道如何设置的request对象有适当@RequestBody的MultiValueMap。我已经尝试了很多设置 request.content、设置 request.accept、request.contentType、request.characterEncoding 的变体，但仍然每次出现 415 错误。
If it is any help, I can successfully Post to this endpoint using the web interface, and here is what the request looks like in chrome:
如果有任何帮助，我可以使用 Web 界面成功发布到此端点，这是请求在 chrome 中的样子：

I ended up solving this by doing the following:
我最终通过执行以下操作解决了这个问题：
MockHttpServletRequestBuilder request = MockMvcRequestBuilders.post("whatever url");
request.contentType(MediaType.APPLICATION_FORM_URLENCODED);
//set key value pairs
//also the keys do not have to be unique, two keys of the same value will both get added
request.param("key", "value");
MockMvc mockMvc = MockMvcBuilders.webAppContextSetup(applicationContext).build();
ResultActions resultActions = mockMvc.perform(request);
// make sure response is valid
Hope this can lead someone else in the right direction. Thanks
希望这可以引导其他人朝着正确的方向前进。谢谢
