JSON.parse从Web API返回未定义

Question

当我尝试使用JSON.parse（）时不会返回任何内容。

fetch(
      "SOMEWEBSERIVCE!!!!!!!!!",
      {
        method: "POST",
        headers: new Headers({
          Accept: "application/json",
          "Content-type": "application/json" // <-- Specifying the Content-Type
        })
      }
    )
      .then(Response => Response.text())
      .then(x => {
        const str = x.substring(6);
        const str4 = str.substring(0, str.length - 2);
        const str5 = str4.replace(/\\/g, "");
        console.log("str5", str5);
        const dateFormat = /^\d{4}-\d{2}-\d{2}T\d{2}:\d{2}:\d{2}Z$/;
        function reviver  (value){
          if(typeof value==="string"&&dateFormat.test(value)){
            return new Date(value);

          }
          return value;
        }
        const str3 = JSON.parse(str5,reviver);

        console.log("str3", {str3});
        dispatch({ type: FETCH_CHECKLIST_SUCCESS, payload: str3 });
      })

str5 is returning string this output on console:

在解析此str5 str3之后，BUT返回未定义。
