ESP32 HTTP Client 报错 今天在使用ESP32中的esp_http_client_init如下 Copy//结构体 typedef struct { char url[256]; } config_t; //主要代码 strncpy(config.url, "http://xxx/xxx", sizeof(config.url) - 1); config.url[sizeof(config.url) - 1] = '\0'; // 确保字符串以空字符结尾 ...

esp_http_client_init():要使用HTTP客户端,我们必须做的第一件事就是esp_http_client通过esp_http_client_config_t配置在此函数中创建一个pass 。我们未定义哪些配置值,该库将使用默认值。 esp_http_client_perform():esp_http_client需要使用init函数创建的参数。此函数执行esp_http_client的所有操作,从打开连接...

Re: esp_http_client.h: No such file or directory PostbySprite»Tue Oct 19, 2021 10:52 am Sorry, but that doesn't answer any of the questions I asked... Can you specifically post the contents of the CMakeLists.txt in the component where you are trying to use esp_http_client?
WiFiClient client; if (!client.connect(serverIP, serverPort)) { Serial.println("Connection failed"); return; } client.print("GET /data HTTP/1.1\r\n"); client.print("Host: "); client.print(serverIP); client.print("\r\n");
The esp_http_client_config_t has a buffer_size attribute (that defaults to DEFAULT_HTTP_BUF_SIZE = 512). Larger responses lead to multiple HTTP_EVENT_ON_DATA. I thought there was only one HTTP_EVENT_ON_DATA for non-chunked HTTP requests, which is not the case. ...
