我正在努力解决这段代码而我无法理解它。 所以我设法从JSON中的api返回。我在String Client中收到回复。但我无法从这个字符串中获取任何数据。我已经检查了我的代码几个小时但没有接近。这里出了什么问题？
我的JSON代码是：

我的ESP8266代码是：

Serial.println("==========");
Serial.println("closing connection");
digitalWrite(gpio13Led, LOW);
json = json + line;
Serial.print("json");
Serial.println(json);
}
// Reading JSON
DynamicJsonBuffer jsonBuffer(10833);
JsonObject& root = jsonBuffer.parseObject(json);
Serial.print("JsonObject: ");
JsonObject& thermoStat = root["devices"]["thermostats"]["e97ayjdpIOkPa4vZFxHggZMXiHKfhsyU"];
const char* hvacState = thermoStat["hvac_state"]; // "heating"
Serial.println("hvac");
Serial.print(hvacState);
//compare hvacState
if (hvacState == "off") {
Serial.print("Off");
}
if (hvacState == "heating"){
Serial.print("On");
}
}
我的串口输出是：
reply was:

==========
closing connection
json
JsonObject: hvac
类似的代码mentioned here 确实有效。但是我在使用const char *，而现在我从字符串中得到了api的响应。我不知道如何以不同的方式做到这一点。
在答案中提出一些建议之后，我尝试使用以下代码来获取相同的JSON代码：
#include <ArduinoJson.h>
void setup() {
Serial.begin(115200);
Serial.println("TEST START");
//Serial.println("Buffer" + bufferSize);
const char* json = "{\blanked oUT}}";
Serial.println(json);
DynamicJsonBuffer jsonBuffer(10833);
JsonObject& root = jsonBuffer.parseObject(json);
//Serial.print("JsonObject: ");
//Serial.println((int)root["devices"]["thermostats"]["e97ayjdpIOkPa4vZFxHggZMXiHKfhsyU"]);
JsonObject& thermostat = root["devices"]["thermostats"]["e97ayjdpIOkPa4vZFxHggZMXiHKfhsyU"];
const char* hvacState = thermostat["hvac_state"]; // "heating"
Serial.println("hvac:");
Serial.println(hvacState);
if (hvacState == "off") {
Serial.print("Uit");
}
if (hvacState == "heating"){
Serial.print("Aan");
}
}
void loop() {
// put your main code here, to run repeatedly:
}
然后是：
TEST START
{"devices":{all blanked out}}
hvac:
off
正如您所看到的，除了IF()之外，其他一切都有效。但是，如果我将const char*更改为String代码无法正常工作。不幸的是我需要解析一个字符串才能让我的完整代码工作。
答案 0 :(得分：0)
可能值得使用您传递给JSON对象的硬编码JSON字符串进行单独测试，以确保解析按预期工作。
ArduinoJSON Assistant应该有助于存根JSON解析。
根据您的评论和JSON content on your other question，您可能会感到不完整或混乱。
这是JSON响应的手动格式化版本。请记住，最后一部分只是确保使用有效的JSON对象：
{

{
"thermostats":

有了这个，ArduinoJson助手可以生成解析代码：
const size_t bufferSize = 3*JSON_OBJECT_SIZE(1) + JSON_OBJECT_SIZE(3) + JSON_OBJECT_SIZE(37) + 1100;
DynamicJsonBuffer jsonBuffer(bufferSize);

回到你的问题：＆＃34; hvac_state＆＃34;此数据中不存在，因此这可能是您尝试无效的原因之一。
此外，如评论中所述，测试ESP外的api响应（计算机上的普通请求）以确保按预期工作。如果是，请调试传递给Arduino / ESP代码中的JSON对象的字符串如何连接（如果所有数据都以正确的顺序排列等）。
答案 1 :(得分：0)
好的，我找到了问题的答案。有点.. 最后，我注意到api的响应从未完成。 所以解析可能从来没有奏效。
