Azure java函数post方法,发送formdata
我在这里学习了这个教程 functions-create-first-java-maven
除此之外,我正试图做的只是拥有一个post方法,并在请求体中传递表单数据
这是我的函数代码
@FunctionName("create-request")
public HttpResponseMessage run(@HttpTrigger(name = "req", methods = { HttpMethod.POST }, authLevel = AuthorizationLevel.ANONYMOUS) final HttpRequestMessage<Optional<String>> request,
final ExecutionContext context) {
context.getLogger().info("Java HTTP trigger processed a request.");
context.getLogger().info("RequestBody:- " + request.getBody());
final int keyIndex = request.getBody().toString().indexOf("request");
if (keyIndex != -1) {
final String restString = request.getBody().toString().substring(keyIndex);
return request.createResponseBuilder(HttpStatus.OK).body("Hello, " + restString).build();
}
return request.createResponseBuilder(HttpStatus.BAD_REQUEST).body("Please pass a name on the query string or in the request body").build();
}
没有响应,但我的本地控制台显示了大量异常
这似乎是这里的主要问题

但是,有趣的是,当我传递与x-www-form-urlencoded相同的数据时,它工作得很好
因此,我想知道是否需要修改@HttpTrigger参数并传递一些其他配置来指定函数应该支持的、表单数据以及URL编码方式?因为,我更喜欢将数据作为表单数据传递,而不是作为URL编码传递。 欢迎提出任何建议

Httptrigger函数目前似乎不支持
form-data
内容类型我的解决办法是我们可以添加逻辑来处理它
我们可以从请求头中获取内容类型,然后自己处理该值
下面是演示代码
