一、問題現象

在使用rest-assured呼叫企業微信建立部門介面時，遇到如下問題：

java.lang.IllegalStateException: You can either send form parameters OR body content in POST, not both!

建立部門介面文件截圖：

可見，access_token沒有拼接到建立部門的URL後面

三、解決方案：

post請求的傳送修改成下面樣例

given().
        queryParam("name, "value").
        body(..).
when().
        post(..);

即param ()修改成queryParam()

四、官網解釋

Parameters

通常你指定這樣的引數：

given().
       param("param1", "value1").
       param("param2", "value2").
when().
       get("/something");

REST Assured 將根據 HTTP 方法自動嘗試確定哪種引數型別（即查詢或表單引數）。 在 GET 查詢引數的情況下將自動使用，在 POST 表單引數的情況下將使用。 在某些情況下，將 PUT 或 POST 中的表單和查詢引數分開是很重要的。 然後你可以這樣做：

given().
       formParam("formParamName", "value1").
       queryParam("queryParamName", "value2").
when().
       post("/something");

總結：在使用rest-assured傳送請求時，使用get方法，則使用param；而使用post或put時，則使用queryParam或formParam
